How to Send a Complete Pipe Fitting RFQ

A piping fitting RFQ needs more than an alloy name and nominal size. This guide organizes geometry, product route, connecting pipe dimensions, schedule or wall, end preparation, dimensional basis, quantity, inspection, documentation, marking, packing, and destination details so elbows, tees, reducers, caps, stub ends, and forged fittings can be reviewed against the intended piping requirement.

Working method

Use the checklist to create a technical record before issuing the RFQ.

Working method

Four controls before technical quotation.

01

Name the fitting

State elbow, tee, reducing tee, concentric reducer, eccentric reducer, cap, stub end, or forged fitting.

02

Define the geometry

Include NPS, OD, schedule or wall, centre-to-end or drawing dimension, reducer orientation, and end preparation.

03

Set the material route

State grade, UNS, ASTM or ASME material standard, dimensional standard, and project requirement.

04

Plan inspection and logistics

List PMI, MTC, dimensional report, marking, packing, destination, documents, and target delivery.

Technical checklist

What to make explicit in the order.

Fitting form

State the exact component, including equal or reducing tee and concentric or eccentric reducer.

Fit-up data

Confirm NPS, OD, wall or schedule, bore, bevel, socket weld, threaded, or drawing-controlled ends.

Dimensional route

State ASME B16.9, ASME B16.11, or the project drawing rather than assuming equivalent geometry.

Quality evidence

Name any PMI, IGC, NACE, NDE, MTC, TPI, marking, and release-document requirements.

Document controls

Release evidence should match the order.

Dimensional report

Request it when centre-to-end, wall, bevel, bore, reducer orientation, or drawing dimensions require evidence.

Certificate reconciliation

Match the certificate grade, product form, standard, test results, and heat number to finished item markings.

Packing instruction

Define protection for bevels or machined surfaces, segregation, crate marking, and destination documentation.

Buyer questions

Frequently asked questions.

What schedule should be given for a buttweld fitting?

State the matching pipe schedule or exact wall and bore required by the drawing or piping class.

Why is reducer orientation important?

Concentric and eccentric reducers serve different fit-up and drainage or gas-handling conditions, so the required orientation must be specified.

Can a drawing replace a standard?

A drawing can control a custom component, but the RFQ should clarify whether it supplements or replaces the normal dimensional standard.

Ready to define an order?

Prepare a technical quotation request.

Use the advanced RFQ to capture the component, material, standards, dimensions, inspection, documents, packing, and destination requirements in one reviewable form.
