Seamless vs Welded Steel Pipe: Prepare the Right Enquiry

Seamless and welded describe different pipe manufacturing routes. Choosing a pipe requires more than selecting one of those labels. Begin with the governing project specification.

Identify the standard and service

State the required material standard, grade and service conditions. If the project specifies a particular manufacturing route, include it in the enquiry. A general claim that one pipe type is always better is not a substitute for the approved specification.

Define the dimensions

Give outside diameter and wall thickness, or an unambiguous nominal size and schedule. Add length, dimensional tolerances, end preparation and surface requirements.

Include inspection requirements

Confirm which tests, inspection documents and traceability details are required. Ensure these appear in the quotation so the offer can be checked against the purchase specification.

Ask about delivery

List quantity by size, packing, destination and desired schedule. Shanghai Qijian accepts separate seamless and welded pipe enquiries and confirms the offered specification with the buyer.
