How to prepare a steel pipe RFQ

Start with the governing documents

A material list is useful, but it rarely contains every purchase requirement. Include the piping or pipeline specification, data sheets, approved-vendor rules, inspection requirements and any project notes that override the base standard.

Describe every line item unambiguously

For pipe, identify the standard, grade, size, wall thickness or schedule, manufacturing route where mandatory, quantity, length, end finish and delivery condition. Add coating, lining, supplementary tests and special tolerances.

Define certification and inspection before pricing

State whether EN 10204 type 3.1 or 3.2 certification is required, whether third-party inspection applies and which activities are hold or witness points. Use the MTC 3.1 and 3.2 guide to define the certificate route before the order is placed.

Give logistics enough information

Provide the delivery destination, required date, preferred Incoterm if known, site or port constraints and whether split shipments are acceptable.

Invite a controlled clarification

Ask suppliers to list deviations, exclusions and assumptions in a structured form. A clear deviation register makes comparison faster.

Procurement note

This article is general guidance. The project specification, current standard edition and qualified engineering review remain controlling.
