Forged Pipe Fittings Procurement Guide: Key Trends and Best Practices for EPC Buyers

Request a material test report (MTR) that lists chemical composition and mechanical properties for each heat number.

Inspection Documents You Must Request

Reliable suppliers provide the following documentation:

• Material Test Report (MTR) per EN 10204 3.1 or 3.2
• Certificate of Conformance (if MTR is not available)
• Dimensional inspection report confirming tolerances per relevant standard
• NDE reports (ultrasonic, magnetic particle, liquid penetrant) if specified in the purchase order
• Heat treatment chart for fittings requiring normalizing, quenching, or tempering

RFQ Checklist for Forged Fittings

Include these details in your request for quotation to avoid mismatches:

• Material grade (e.g., A105, F304, F316L)
• Standard and class (e.g., ASME B16.11 Class 3000)
• Type (elbow, tee, coupling, cap, bushing, etc.)
• Size and schedule (e.g., 2" Sch 80)
• End connections (socket weld, threaded, or NPT)
• Quantity per size/type
• Coating/packaging requirements (e.g., galvanized, epoxy, or oiled for rust prevention)
• Third-party inspection requirement (e.g., Lloyds, DNV, or BV)
• Delivery location and incoterms

Common Quality Risks and How to Avoid Them

1. Incorrect chemical composition – Always request MTR and verify traceability.
2. Dimensional deviations – Request sealing dimensions (socket depth, shoulder width) and perform random checks.
3. Surface defects (cracks, laps) – Specify that fittings be free of defects per ASTM visual acceptance criteria.
4. Inadequate heat treatment – Confirm temperature and holding time records when required by the standard.
5. Mixed material – Insist on color coding or stamping of grade on each fitting.

Mitigate risks by conducting supplier audits and requesting a pre-shipment inspection (PSI) report.

What to Send Before Quotation

To receive accurate pricing and lead times, provide:

• A clear RFQ with full specifications (use the checklist above)
• Expected order volume and delivery schedule
• Any special material requirements (e.g., impact test at -50°C)
• Preferred third-party inspection agency, if any
