What is the difference between stainless pipe and stainless tube orders?

Pipe orders are often specified by NPS and schedule for pressure or fluid service, while tube orders are often specified by outside diameter, wall thickness, surface and dimensional tolerance.

Which ASTM standards are common for stainless pipe and tube?

ASTM A312 is commonly used for seamless and welded austenitic stainless pipe, ASTM A269 for general service stainless tubing, ASTM A213 for boiler, superheater and heat exchanger tubing, and ASTM A554 for welded mechanical tubing.

Size confirmationPipe orders often use NPS and schedule; tube orders usually confirm outside diameter, wall thickness, length, tolerance and surface finish.

Surface and testingAnnealed and pickled, pickled, bright annealed, brushed, polished or passivated surface; PMI, hydrotest, eddy current, flattening or intergranular corrosion test by order.

Order detailsConfirm standard, grade, seamless or welded route, NPS or OD, wall or schedule, length, surface, test, MTC, packing and destination port.

Typical Applications

Where stainless pipe and tube is specified

Process and fluid linesChemical, water treatment, food service, brewery, pharmaceutical and general corrosion-resistant process lines.

Heat and equipment tubingHeat exchanger, boiler, condenser, instrument, mechanical and equipment tubing where grade and testing are controlled.

Decoration and fabricationArchitectural railings, furniture, frames, visible tube, square tube assemblies and polished stainless fabrication.

Pipe versus tube note

State whether the order is NPS/schedule pipe or OD/wall tube. This affects dimensional language, tolerance, inspection and quotation route.

Grade and surface note

For 316L, sanitary or decorative tube, confirm surface finish, polishing grade, passivation, packing protection and whether PMI or special testing is required.
