Forged Fittings RFQ Document Checklist

Prepare your forged fittings RFQ with clear sizes, end connections, material requirements and supporting documents. Use this checklist for socket-weld and threaded fittings to reduce clarification rounds before quotation.

1. Start with the fitting item list

Use one line for each fitting configuration. Separate elbows, tees, couplings, caps, plugs and bushings, even when the nominal size and material are the same. Give every line an item number that also appears on drawings and document requests.

2. Identify every connection

For socket-weld fittings, identify the mating pipe size and wall thickness or schedule. Attach a drawing when the bore, socket geometry or other dimensions differ from the specified standard. Keep special machining requirements visible in the item description.

For threaded fittings, state the thread standard and designation, not simply “threaded.” Identify male or female connections at every port and distinguish tapered from parallel threads where relevant. Do not assume that connections with similar names or nominal sizes will mate.

For reducing tees and other multi-port items, label the run and branch sizes on a sketch. For mixed-end fittings, map each end separately. If requesting a union or a replacement union component, provide its governing specification, drawing and mating-part details; do not assume components from different designs are interchangeable.

3. Separate class, material and service requirements

ASME B16.11 covers forged socket-welding and threaded fittings. Its class designations include 2000, 3000 and 6000 for threaded ends, and 3000, 6000 and 9000 for socket-weld ends. Specify the applicable fitting type and connection together with the class, where the standard assigns one. Class and size availability depend on the fitting type; do not apply one class list to every product. For plugs, bushings and other items with different designation rules, state the exact product and governing standard, and ask the supplier to confirm the applicable rating basis.

A class number alone is not a complete statement of allowable service pressure. Include the project piping specification and any design pressure, design temperature or fluid-service requirements that affect selection. The project designer should confirm suitability under the applicable piping code.

Keep the material specification separate from the fitting standard. ASTM A105/A105M concerns carbon steel forgings for piping applications; ASTM A182/A182M covers alloy and stainless steel piping components including forged fittings. For a graded specification, state the complete grade rather than only “stainless steel” or “alloy steel.” Identify required heat treatment and supplementary requirements explicitly.

4. Attach the project documents that apply

• Item list or material take-off with revision number and quantities.
• Piping material specification and applicable standard editions.
• Drawings for reducing, mixed-end, nonstandard or replacement items.
• Inspection and test requirements, including witness or hold points.
• Marking, preservation, packing and shipping instructions.

Highlight any conflict between the item list and the project specification. State which document takes precedence and ask for deviations to be listed separately in the quotation. If a requirement is undecided, mark it “to be confirmed” instead of leaving it open to interpretation.

5. Define inspection and traceability requirements

Specify the required inspection certificate or material test report and the traceability expected between the fittings, packaging and records. If the project requires positive material identification (PMI), hardness testing, impact testing or additional examination, identify the applicable procedure or specification, scope and acceptance criteria.

Clarify any third-party inspection, approval steps and document review periods before quotation. Include special marking and end-protection requirements. Refer to our quality and inspection information when preparing the enquiry, and list the project-specific requirements in the RFQ.

6. Know which documents belong at each stage

A sample certificate can help agree the document format, but it is not the certificate for the supplied goods. Final records should correspond to the actual supply and the requirements agreed in the purchase order.

Example completed item

Item F-01: forged 90-degree elbow; NPS 1; female NPT threads at both ports to ASME B1.20.1; ASME B16.11 Class 3000; ASTM A105; 20 pieces; EN 10204 type 3.1 inspection certificate; thread protection and traceable packing. Quote FCA at the named dispatch location. Standard editions, heat-treatment requirements, project service conditions and requested delivery date to be confirmed against the attached specification.

For a mixed-end item, describe each connection separately, for example: “Port A: NPS 1 female NPT; Port B: NPS 1 socket-weld, mating pipe wall as specified.” Attach a sketch and request confirmation of the applicable design and rating.

Illustrative RFQ example only. Confirm suitability, standard editions and all project-specific requirements before ordering.

8. Check before sending

• Every port has a size and connection type.
• Thread details and mating-pipe information are included where needed.
• The fitting standard, applicable class and material specification are separate fields.
• Drawings and specifications use consistent item numbers and revisions.
• Inspection, certification and approval requirements are stated.
• Quantities, destination and requested delivery date are clear.

9. Send your forged fittings RFQ

Send your item list and applicable project documents. Mark unresolved details for clarification during quotation review.
