Production-route guidance
Engineering pipe route, inspection and document checkpoints
This explains the checkpoints a buyer should verify. It does not claim that KeelGauge manufactures the product or that every supplier uses the same route.
- 01
Select a seamless, ERW, LSAW, SSAW, or other project-approved production route.
- 02
Verify grade, PSL, service condition, plate, coil, or billet traceability.
- 03
Complete piercing and rolling or forming and welding according to the selected route.
- 04
Apply heat treatment, sizing, straightening, end preparation, or threading as required.
- 05
Complete chemistry, mechanical, hydrostatic, NDT, dimensional, and witness checks.
- 06
Apply FBE, 3PE, 3LPP, paint, end protection, marking, and document-controlled packing.

Buyer questions
Oil & Engineering Pipe RFQ FAQ
Answers are procurement guidance. Final compliance depends on the selected supplier, product scope, documents, and contract.
What service information is needed for oil or engineering pipe sourcing?
Identify whether the requirement is line pipe, casing, tubing, process piping, pressure equipment or general engineering use. Provide fluid, design pressure and temperature, corrosion or sour-service conditions, dimensions, grade, product standard, PSL or supplementary requirements, ends, coating, inspection, quantity and destination.
How should API, PED or project certificates be verified?
Check the legal manufacturer and factory, certificate number and validity, applicable product and grade scope, standard edition, quality-system scope and any notified-body or licensing limits. The selected batch documents must remain traceable to the quoted manufacturing route; a general company certificate does not prove every pipe complies.
When should third-party inspection be added to an engineering pipe RFQ?
Add it before quotation whenever the contract, end user or risk level requires witness, hold or document-review points. Define the agency, inspection and test plan, notice period, acceptance documents, reinspection responsibility and cost allocation so suppliers can quote time and cost consistently.
Supplier evidence is matched to the final route
Standards, listings, MTCs, coating records, inspection reports, and project references must belong to the applicable selected supplier and product scope.
