What to confirm before requesting pipe and fittings quotation

Pipe quotations depend on process route, standard, OD, WT, length, end finish, coating, testing, marking, and bundling.

Inquiry parameters

  • Confirm pipe or fitting type, standard, grade, OD, WT, SCH, length, and tolerance.
  • Confirm end finish such as plain end, beveled end, threaded end, coupling, or grooved end.
  • State coating, galvanizing, painting, marking, hydro test, NDT, or API inspection requirements.
  • Share quantity, bundle weight, packing method, destination port, and certificate requirements.

Packing and documents

  • Use hexagonal bundles, steel straps, plastic caps, waterproof wrapping, or wooden cases for fittings.
  • Confirm MTC, hydro test record, inspection certificate, packing list, invoice, and shipping marks.
  • For OCTG or API line pipe, confirm color bands, stencil marking, and traceability requirements.

Quality checks

  • Check OD, WT, length, ovality, straightness, and end finish before shipment.
  • Use hydro test, NDT, flattening, bending, or drift tests according to standard and application.
  • Confirm heat number, pipe marking, bundle tags, and MTC consistency.

Procurement FAQ

Common sourcing questions

What information is needed for a steel pipe quotation?

Please provide standard, grade, OD, wall thickness, length, end finish, quantity, coating, testing, marking, packing, and destination port.

Can seamless pipe, welded pipe, and fittings be quoted together?

Yes. A combined pipe package can be reviewed when each item has clear size, standard, grade, quantity, end finish, and testing requirements.

Which tests are common for pressure or line pipe orders?

Common checks include hydro test, NDT, dimensional inspection, visual inspection, mechanical tests, and MTC review according to the requested standard.
