API 6A Wellhead Equipment Forgings — Casing Head, Tubing Head, Christmas Tree Component Forgings
Shivam Forge manufactures forgings to API 6A (Specification for Wellhead and Christmas Tree Equipment) — casing head, tubing head, and Christmas tree valve body and flange forgings — in PSL (Product Specification Level) 1 through PSL 4 material grades, PR (Performance Requirement) 1 and 2, for onshore and offshore oil and gas wellhead applications. NACE MR0175 sour service compliance, EN 10204 3.1/3.2 certification. Rajkot, India. Call +91-9265772827.
API 6A governs the material, design, and testing requirements for wellhead and Christmas tree equipment — the pressure-containing components sitting at the top of an oil or gas well, controlling and monitoring flow between the reservoir and surface production facilities. Given wellhead equipment's role as the primary pressure barrier between a potentially high-pressure hydrocarbon reservoir and the surface environment, API 6A's requirements are structured around a tiered system reflecting increasing criticality: Product Specification Levels (PSL 1 through PSL 4) define progressively more rigorous testing and documentation requirements, while Performance Requirements (PR1 and PR2) define design validation testing rigor. Understanding and correctly applying this tiered specification framework — rather than treating API 6A as a single uniform standard — is fundamental to supplying wellhead component forgings that genuinely meet project requirements rather than merely referencing the standard's name.
Forged casing head body components, the wellhead's base component providing the connection and seal for the well's outermost casing string, engineered per API 6A material and dimensional requirements for the specific pressure rating and PSL the well design requires.
Forged tubing head body components sitting above the casing head, providing the connection and seal for the production tubing string, per API 6A specification requirements matched to well pressure and service conditions.
Forged valve body components for Christmas tree assemblies (the valve arrangement controlling flow at the wellhead), engineered for the pressure containment and flow control function these critical wellhead components provide.
Forged adapter flange and spool components connecting different wellhead assembly sections, per API 6A dimensional and material requirements ensuring compatibility across the complete wellhead assembly.
Material and testing documentation matched to the specific Product Specification Level a project requires — PSL 1 (basic requirements) through PSL 4 (most rigorous, including full traceability and enhanced NDT), since PSL selection directly determines the testing rigor and documentation package a given wellhead component order requires.
Design and material documentation supporting PR1 (standard) or PR2 (validated design with additional testing) performance requirement compliance as specified by the project or end customer.
Material qualification compliant with NACE MR0175 / ISO 15156 sulphide stress cracking resistance requirements for wellhead components specified into sour (H2S-containing) service applications.
Complete material traceability and certification per EN 10204 3.1, with 3.2 third-party witnessed certification available, matched to the documentation rigor the specified PSL requires.
API 6A's role as the defining specification for wellhead and Christmas tree equipment reflects the genuinely critical safety and pressure-containment function this equipment category serves: wellhead components sit at the literal boundary between a potentially high-pressure hydrocarbon reservoir and the surface environment, making them among the most safety-consequential pressure-containing equipment in the entire oil and gas production chain. This criticality is precisely why API 6A structures its requirements through a tiered system rather than a single uniform specification — recognizing that not every wellhead application carries identical risk, and that appropriately matching testing and documentation rigor to actual application criticality serves the industry better than either under-specifying critical applications or over-specifying routine ones.
The Product Specification Level (PSL) framework, running from PSL 1 through PSL 4, captures this risk-tiered approach directly: PSL 1 establishes baseline material and testing requirements suitable for less demanding applications, while PSL 4 imposes the most comprehensive testing and full material traceability requirements, typically specified for high-pressure, high-temperature, or otherwise particularly demanding well applications where component failure consequence is most severe. Genuinely understanding which PSL a specific wellhead component order requires — rather than defaulting to a single testing package regardless of application — is fundamental to both meeting project specification correctly and avoiding unnecessary cost from over-testing components where the application doesn't warrant the highest PSL tier.
Performance Requirements (PR1 and PR2) add a further dimension to API 6A compliance, addressing design validation rather than material testing specifically: PR2 requires additional validated design testing demonstrating the wellhead component design itself has been proven through testing beyond PR1's standard requirements, a distinction that matters for genuinely novel or particularly demanding wellhead designs where design validation, not merely material quality, represents a meaningful project risk consideration.
For wellhead equipment manufacturers and oil and gas operators sourcing API 6A compliant forged casing head, tubing head, or Christmas tree components, Shivam Forge offers PSL and PR-matched documentation with NACE MR0175 sour service compliance support.

PSL (Product Specification Level) defines the tier of testing and documentation rigor required, from PSL 1 (basic requirements) through PSL 4 (most rigorous, including full material traceability and enhanced non-destructive testing). Higher PSL requirements apply to more critical wellhead applications where component failure consequence is more severe, such as high-pressure or sour service wells.
PR1 and PR2 (Performance Requirements) define the design validation testing rigor for wellhead equipment — PR2 requires additional validated design testing beyond PR1's standard requirements, typically specified for more demanding or critical service applications.
Yes. Material qualification compliant with NACE MR0175 / ISO 15156 sulphide stress cracking resistance requirements for wellhead components specified into sour (H2S-containing) service applications.
