What is a Frac Head (Goat Head) & Its Main Role in Wellhead Christmas Tree?

A goat head wellhead forging, also known as a forging frac head or fracturing head, it is a mission-critical, precision-forged flow control component of the wellhead Christmas tree and frac tree assembly. Installed as the connection of the frac tree, this engineered flow cross serves as the primary interface between high-pressure treating iron and the wellbore, where pressurized fracturing fluid, proppant, and treatment chemicals enter the frac tree to execute hydraulic fracturing operations.

Our industry-leading forged goat heads has an improved 45-degree angled inlet design, validated via CFD flow field simulation, which maximizes turbulent-free fluid flow rate, minimizes proppant erosion and pressure drop, while reducing the overall size and weight of the wellhead assembly. We provide both studded and flanged end connections that are made to fit with the interfaces of existing wellhead Christmas trees, and all our products can meet the installation needs of both onshore and offshore projects.


Why Choose Forged Frac Heads? Main Performance Advantages

The parts that used in hydraulic fracturing must be very strong to handle stress and have structural integrity. Open die forging is the best production processing for frac heads and goat heads. It is safer and works better than cast components:

Superior Structural Integrity

Our forging process uses a minimum 3:1 forging ratio to refine the steel grain structure, eliminating internal porosity, shrinkage, and inclusions common in cast parts. This process can reduce the risk of catastrophic failure under 10000-20000psi cyclic high pressure, which is a critical safety requirement for wellhead operations.

Enhanced Mechanical Performance

Forged frac heads are stronger in tension by 30-40 percent, which can affect resistance, and they last longer than cast parts. The material properties are the same throughout the entire forging.  Our controlled heat treatment process gives you the perfect balance of hardness (22–32 HRC) and toughness at low temperatures, making it great for use in the Arctic and in deep water.

Superior Corrosion & Erosion Resistance

Uniform, refined grain structure from forging improves resistance to sulfide stress corrosion cracking (SSCC) in sour gas environments and proppant erosion during continuous fracturing operations. Compared to standard designs, our CFD-optimized inlet design cuts erosion rates by another 30%.

Complete Material Traceability

Our forged frac heads have 100% batch traceability from raw steel melting to final inspection, according to API 6A PSL1-PSL4 requirements for offshore and critical well applications. We provide complete EN10204 3.1/3.2 Mill Test Certificates (MTC) with every order.

Four Forging Frac Head Series: Matched to Your Well Conditions

The Three Ways a Frac Head Fails in the Field — And How Forging Stops All Three

Most pages for products will only show their certifications. We think our clients should know exactly what threatens their frac head at 2:00 AM during a multi-stage completion job and why the metallurgical choices we made at the forging press get rid of those threats at the source. Based on 25 years of feedback from the field, our engineering team has looked at these three ways that things can go wrong and how our forging process stops each one.

⚡

Failure Mode 1 — Proppant Erosion & Hydraulic Gouging

The most common failure mode in high-cycle, high-rate fracturing operations

⚠ Root Mechanism During multi-stage fracturing, proppant-laden slurry (typically 2–8 ppg sand concentration) accelerates through the frac head at flow rates exceeding 60–100 bbl/min. At every directional change — particularly at the 45° inlet elbow and the flow cross bore transition — kinetic energy converts to localized impact pressure. In cast components, dendritic grain boundaries and micro-porosity (typical in sand cast or investment cast parts) act as stress concentrators, initiating micro-crack networks that propagate under cyclic hydraulic loading. The result: a component that appears intact but has lost 40–60% of its wall thickness internally before any external indication appears.
✓ How We Stop It Our minimum 3:1 forging ratio mechanically breaks down the as-cast dendritic structure into a continuous, directionally aligned grain flow that follows the component contour. This closes micro-porosity and eliminates the stress riser network that erosion exploits. We additionally validate inlet geometry via Computational Fluid Dynamics (CFD) simulation for each new design, improving the inlet angle and bore transition radius to reduce localized fluid velocity peaks by up to 25%. In repeated field measurements across Permian Basin customers, our forged bodies show erosion rates 30–35% lower than cast alternatives at equivalent operating conditions after 100+ fracturing stages.
🛡

Failure Mode 2 — Sulfide Stress Corrosion Cracking (SSCC)

The silent failure: no warning signs until catastrophic fracture

⚠ Root Mechanism SSCC is a form of hydrogen embrittlement. In the presence of H₂S (even at partial pressures as low as 0.0003 MPa per NACE MR0175 threshold), atomic hydrogen generated by the cathodic corrosion reaction diffuses into the steel lattice and accumulates at microstructural defects — grain boundaries, non-metallic inclusions, dislocation pile-ups, and regions of residual tensile stress from welding or improper heat treatment. Under sustained tensile loading from wellhead pressure, these hydrogen-enriched zones initiate brittle transgranular or intergranular cracks with zero plastic deformation, no ductile warning. Components commonly fail at stress levels well below their rated yield strength. The failure is particularly dangerous at high-hardness zones (HRC >22) and near inclusions, both of which are amplified in castings with poor material cleanliness.
✓ How We Stop It For sour service frac heads, our response is systemic, not cosmetic. First, we specify EFVD or ESR melted steel with verified inclusion content that meet ASTM E45 Method D, Chart 1, Level ≤1.0 — this eliminates the hydrogen traps at the microstructural level. Second, our heat treatment process controls final hardness to ≤22 HRC per NACE MR0175/ISO 15156 Table 1, verified on each forging by calibrated Rockwell hardness tester with documented records. Third, we apply controlled tempering to minimize residual stress and maximize tempered martensite uniformity, which dramatically reduces local hydrogen activity coefficients. The result: no SSCC-related field failures in our 14 approved sour gas well supply projects across the UAE and Saudi Arabia over a combined service period exceeding 45 well-years.
📈

Failure Mode 3 — High-Cycle Pressure Fatigue Cracking

Invisible cumulative damage from pressure cycling across thousands of fracturing stages

⚠ Root Mechanism Modern multi-stage completions subject the frac head to thousands of pressure cycles — pressure build-up to treating pressure (often 10,000–15,000psi), hold, then pressure bleed-down between stages. Each cycle imposes a mean stress plus alternating stress on the body wall, inlet bosses, and flange ligaments. Per Basquin's law for high-cycle fatigue, crack initiation life decreases exponentially with stress amplitude. In components with surface defects, subsurface shrinkage voids, or non-metallic stringer inclusions (all common in castings), crack nucleation can begin at 10–20% of the theoretical fatigue life. The highest-risk zones are the inner bore transition radius, the stud hole ligaments, and any weld repair areas — locations where stress concentration factors (Kt) can reach 2.0–3.5.
✓ How We Stop It Our forging process generates compressive residual stresses at the component surface through the die forging and controlled cooling sequence — the exact opposite of the tensile residual stresses that accelerate fatigue crack initiation. The refined, equiaxed grain structure produced by our controlled heat treatment (normalized + quench + temper with computer-logged thermal profiles) has consistent Charpy V-notch impact energy exceeding 60J at −46°C across the entire forging cross-section, verified per batch to ASTM E23. We machine inner bore transition radii to drawing-specified fillets (typically R≥3mm minimum) and verify surface finish to Ra ≤0.8µm on all sealing and high-stress surfaces, removing the micro-notch surface defects that used as fatigue crack nucleation sites. High-pressure series frac heads undergo additional in-house cyclic pressure testing at 1.25× rated pressure for 500 cycles as a standard qualification step.

Field-Proven Performance: Real Project Case Studies

It's easy to write numbers on a product page. The following are real supply cases from our 25 years of field work, each with a real engineering problem, a specific solution we came up with, and a measurable result that our clients confirmed in writing.

Permian Basin, USA

High-Cycle Fatigue Challenge in 1,500-Well Multi-Stage Completion Program

📋 The Problem

An independent E&P operator running a 1,500-well pad drilling program in the Midland Basin was experiencing frac head body fatigue cracking at the inlet boss root radius after an average of 180 fracturing stages per well — well below their 250-stage design target. Post-failure metallurgical analysis by their third-party lab confirmed crack initiation at subsurface shrinkage microporosity in their existing cast supplier's components. Their completion schedule was at risk.

⚙ Our Engineering Solution

We redesigned the inlet boss geometry by using FEA (Finite Element Analysis) to reduce the stress concentration factor Kt from 2.8 to 1.6 by increasing the transition fillet radius. We specified AISI 4340 (EFVD) forged at 4.5:1 forging ratio — 50% above our standard minimum — to completely eliminate subsurface micro-porosity. Final heat treatment achieved 26–29 HRC with Charpy impact energy of 85J at −29°C, which exceeding the client's 60J specification by 42%.

📈 Measured Result 6,000+ sets supplied to 1,500+ wells with zero fatigue failures across 270+ stages average per well — exceeding the 250-stage design target by 8% and delivering a confirmed 35% longer service life versus the previous cast supplier.
North Sea, Norway

PSL4 Deepwater Goat Head for Extreme Cold & Corrosion Environment

📋 The Problem

A Norwegian company is working on a deepwater gas field in the Barents Sea. They needed PSL4 goat heads for their subsea Christmas tree, which is 350 meters deep in the water. The parts had to resolve three problems: the seabed temperature was −2°C, which could cause low-temperature embrittlement; the H₂S partial pressure was 0.002 MPa, which required following NACE MR0175 standard; and the NORSOK M-650 material requirements had to be met for all materials. Their current European supplier couldn't make the 14-week delivery window.

⚙ Our Engineering Solution

We chose A182 F53 (2507 Super Duplex Stainless Steel) with ESR melting, which gave us a measured PREN (Pitting Resistance Equivalent Number) of 43.2, which is much higher than the 40.0 minimum needed for seawater service. The forged body was 28 HRC hard (meeting both PSL4 and NACE MR0175 standards) and had a Charpy V-notch of 72J at −46°C (Temperature Class K), as verified by Bureau Veritas in 3.2 witness tests. We got all the NORSOK M-650 material compliance paperwork we needed.

📈 Measured Result 8+ years of continuous subsea service across 8+ deepwater projects with no performance degradation reported. Delivery completed in 11 weeks — 3 weeks ahead of the client's critical path deadline.
Sichuan Basin, China

HTHP Sour Gas Frac Head for 7,000m Ultra-Deep Shale Wells

📋 The Problem

A major Chinese NOC drilling ultra-deep shale gas wells in the Sichuan Basin (target depth 6,500–7,200m) required fracturing heads capable of 15,000psi working pressure and bottomhole temperatures of 160°C at surface. The reservoir contained 3–6% H₂S by volume. Standard material grades available from domestic suppliers could not simultaneously satisfy the high-pressure rating, NACE MR0175 sour service standard, and high-temperature mechanical property retention required.

⚙ Our Engineering Solution

We made a custom modified AISI 4130 alloy forging with controlled amounts of Mo and V. It was then processed through EFVD + ESR double refining. The heat treatment protocol — austenitize at 870°C, water quench, dual temper at 650°C and 600°C — achieved a unique combination: tensile strength 862 MPa, yield strength 758 MPa, hardness 21.5 HRC (below NACE cap), and Charpy energy 95J at −20°C. The material retained full strength at production temperature of 160°C per high-temperature tensile testing to ASTM A370.

📈 Measured Result 4,000+

custom frac heads provided to 350+ ultra-deep shale wells in the Sichuan Basin. No SSCC failures across all H₂S-service wells. The measured life cycle is 40% longer than that of the previous supplier's standard product. Now we became a qualified supplier for the client's next 500-well program.

Technical Glossary: Oil & Gas Wellhead Forging Terminology Explained

This glossary is written for procurement engineers and project managers who need to communicate with technical teams, review supplier quotations, and evaluate specifications — not just for metallurgists. Each definition includes the practical implication for your purchasing decision.

Frac Head / Fracturing Head / Goat Head Three names for the same component: the forged flow cross installed at the top of the frac tree to connect high-pressure treating iron to the wellbore during hydraulic fracturing. "Goat head" refers to the characteristic 45° angled inlets that resemble horns. Procurement note: specify by rated pressure, bore size, and connection type — the name alone is insufficient.
API Spec 6A The American Petroleum Institute standard governing the design, materials, manufacturing, testing, and marking of wellhead and Christmas tree equipment. The current version is the 20th Edition. All frac heads and goat heads must comply with this standard. Procurement note: always verify which edition your supplier's product was designed and tested to — older editions had less stringent requirements.
PSL (Product Specification Level) A way to rank the quality of API 6A. PSL1 is the minimum standard for onshore wells. PSL2 adds written quality programs. PSL3 needs more testing of materials and NDE. Gas testing is added by PSL3G. PSL4 is the strictest standard. It is required for offshore and sour service applications that are critical to safety. It requires full material traceability, third-party witness testing, and production performance testing. When asking for something, be sure to include the PSL level in your request. It has a direct effect on the cost of materials, the time it takes to get them, and the paperwork that needs to be done.
NACE MR0175 / ISO 15156 The international standard for material selection in H₂S-containing oilfield environments (sour service). It defines maximum hardness limits, approved materials, and heat treatment requirements to prevent sulfide stress corrosion cracking (SSCC). Procurement note: any well with H₂S partial pressure ≥0.0003 MPa (0.05 psia) requires NACE-compliant materials — verify your reservoir data before specifying.
SSCC (Sulfide Stress Corrosion Cracking) A brittle fracture mechanism caused by atomic hydrogen (generated by H₂S corrosion reactions) diffusing into steel and accumulating at microstructural defects. SSCC occurs without visible deformation or warning, and is accelerated by high hardness, tensile residual stress, and high-strength steels. Procurement note: never use high-hardness components (HRC >22) in sour service — always verify according to NACE MR0175.
HIC (Hydrogen Induced Cracking) A form of hydrogen damage where atomic hydrogen accumulates at non-metallic inclusions (particularly manganese sulfide MnS stringers), generating enough internal pressure to initiate stepwise cracks parallel to the component surface. Unlike SSCC, HIC does not require applied stress. Procurement note: HIC resistance requires low sulfur steel (<0.002% S) with calcium treatment — always specify in sour service datasheets.
Christmas Tree / Frac Tree The assembly of valves, spools, and fittings installed at the surface of a completed well to control wellbore flow. A "frac tree" is a Christmas tree specifically configured for hydraulic fracturing operations, with additional pressure ratings and inlet connections for treating iron. The frac head (goat head) sits at the very top of the frac tree.
Open Die Forging A hot metalworking process where a heated steel billet is shaped by progressive hammering between flat or simple-contour dies without completely enclosing the workpiece. The process refines grain structure, closes internal porosity, and aligns grain flow to the component shape — the main reason forged frac heads outperform cast alternatives. Note for procurement: Always ask the supplier for the forging ratio. For important wellhead parts, the ratio must be at least 3:1.
EFVD (Electric Furnace + Vacuum Degassing) A two-stage steel production process: primary melting in an electric arc furnace (EAF), followed by secondary refining under vacuum to remove dissolved gases (particularly hydrogen and oxygen) and reduce sulfur content. EFVD steel has significantly fewer non-metallic inclusions and better cleanliness than standard EAF steel — the minimum requirement for API 6A PSL2+ components.
ESR / VAR / VIM High-end remelting methods for making steel that is very clean. Electro Slag Remelting (ESR) passes the steel through a pool of molten slag to get rid of non-metallic parts. VAR (Vacuum Arc Remelting) remelts in a vacuum to get rid of dissolved gases and make macro-segregation less likely. VIM, or Vacuum Induction Melting, melts and combines metals in a vacuum. This is the standard for nickel superalloys. For sour service, use "EFVD + ESR" and for Inconel parts, use "VIM + VAR."
EN10204 3.1 / 3.2 MTC European standard for material inspection documents. Type 3.1 is a Mill Test Certificate (MTC) provided by the manufacturer's own Quality Control department, which certifies that the material meets the specified requirements. Type 3.2 requires additional validation by an independent third-party inspector or the client's representative. Procurement note: offshore and PSL3/PSL4 projects typically require EN10204 3.2 — specify this in your PO to avoid delay.
ITP (Inspection and Test Plan) A document issued before production begins that identifies every inspection and testing activity, the acceptance criteria, the responsible party, and whether the activity requires client witness ("W"), hold ("H"), or review ("R"). The ITP is the master quality control roadmap for the order. Procurement note: always request an ITP — it protects you against discovering a problem after delivery.

Frequently Asked Questions (FAQ) | Forging Frac Head & Goat Heads

In the oil and gas industry, the terms "frac head," "fracturing head," and "goat head" are all used to mean the same thing: the important flow cross component that is put on top of the frac tree/Christmas tree for hydraulic fracturing operations. The term "goat head" comes from the fact that the part has a unique 45-degree angled inlet design that looks like a goat's horns.

API Spec 6A (Specification for Wellhead and Christmas Tree Equipment) is the international standard for oil and gas wellhead equipment. Wellhead frac heads and goat heads are made to this standard. Our products are completely according to the latest API Spec 6A 20th Edition. We offer PSL1-PSL4 levels to meet the needs of different projects.

Our standard forged frac heads can handle pressures between 10,000 and 15,000 psi. For ultra-deep well and high-pressure hydraulic fracturing, we can make custom high-pressure solutions that can handle up to 20,000 psi.

We specialize in custom open die forging solutions. We can manufacture frac heads, goat heads, and other wellhead Christmas tree components 100% according to your custom drawings, material specifications, and project requirements, we provide free engineering support and drawing review throughout the process.

We recommend using modified low alloy steel (AISI 4130/4140 with EFVD melting and hardness ≤22 HRC), duplex stainless steel (A182 F51/F53), or nickel-based super alloys (Inconel 625/718) for sour service wells with H₂S and CO₂ content. These materials are good for very sour environments. Based on the conditions of your well and the H₂S partial pressure data, our engineering team will help you choose the right materials for free.

Standard lead time is 25–30 working days which start from drawing approval and purchase order confirmation. For urgent oilfield workover and well intervention projects, we provide an expedited 15 working-day delivery track — available for selected material grades and standard configurations subject to forge capacity scheduling. Please tell us your urgent requirements at the time of inquiry so we can confirm expedited availability before you commit to a delivery schedule with your client.

Yes, we can support witness inspection and testing by client-nominated TPI agencies. We usually provide  third-party inspection from Bureau Veritas, SGS, Intertek, TÜV SÜD, DNV GL, Lloyd's Register, and RINA, among others. An Inspection and Test Plan (ITP) which identifying all hold points ("H") and witness points ("W") is prepared and submitted to the client and TPI agency before production begins. TPI coordination does not impact our standard delivery schedule for orders with normal TPI advance notice (>3 working days per hold point).

Every order is delivered with a complete Mill Record Book (MRB) containing: EN10204 3.1 (or 3.2 with TPI witness) Mill Test Certificates (MTC) and Certified Material Test Reports (CMTR) for all raw materials; complete chemical composition reports; mechanical test reports (tensile, hardness, Charpy impact); heat treatment records with temperature charts; NDT reports (UT, MT/PT, dimensional); hydrostatic test records where applicable; dimensional inspection report with CMM data; and Certificate of Conformance (CoC) signed by our QC Manager. PSL4 orders additionally include full heat/lot traceability dossiers from raw steel melt to finished forging identification marking.

We can accept both single pieces for new project qualification and production runs of more than 500 units. But for very small orders (1–5 pieces) that need complicated materials (like ESR-melted nickel alloys), we may charge a setup cost recovery fee to cover the minimums for getting the raw materials. Our sales team will be honest with you when they give you a quote.

We have different surface treatment ways to meet the needs of storage, operation, and corrosion protection. For example, we use phosphating (zinc or manganese) to protect items stored indoors, Xylan® (PTFE-based fluoropolymer) coating to protect threaded connections from corrosion and galling, hot-dip galvanizing for outdoor storage in humid or marine environments, spray metallizing (zinc or aluminum) for long-term storage in harsh environments, and bare machined surfaces with VCI (Volatile Corrosion Inhibitor) wrap for standard export packaging.  All surface treatments are applied after final inspection and dimensional verification.

We machine all major oilfield and industrial thread and connection standards: API 6B and API 6BX flanged connections (standard for wellhead and Christmas tree equipment); NPT (National Pipe Taper) and NPT Hammer Union connections for treating iron and manifold integration; BSP (British Standard Pipe) for international markets; BSPT (British Standard Pipe Taper); Weld Neck (WN) for butt-welded pipeline connections; and different proprietary premium thread connections on request. Connection standard is specified by the client in the drawing or purchase order.

Standard payment terms are 30% advance payment with purchase order confirmation, and 70% balance payment against a copy of the bill of lading (or before shipment for first-time clients). We also accept payment via confirmed Letter of Credit (L/C) at sight — all required documents for L/C compliance (commercial invoice, packing list, bill of lading, certificate of origin, MTC copies) are provided within 24 hours of vessel departure. Available incoterms include: FOB Shanghai (or Tianjin / Qingdao upon request), CIF to any named destination port, and DDP (Delivered Duty Paid) to main global ports upon arrangement.
