The AISI 304 SS Pipes products manufactured by Industrial Tube are predominantly made from austenitic stainless steel. This type of stainless steel has excellent corrosion resistance, stable grain structure at all temperatures, and can be easily welded with standard tungsten inert gas (TIG) equipment, without causing hardening.

To produce outstanding quality AISI 304 SS Pipes products, stainless coil is roll formed, TIG welded and the outside diameter precisely sized to meet tolerances defined in specifications or customer requirements. When required, the internal weld upset is rolled flush to the inside surface of the tube (cold worked). This process creates a uniform, smooth internal finish, ideal for hygienic applications. Standard stock and customised lengths are then cut off as the tube exits the manufacturing process. Along with rigorous testing a number of additional processes may be required depending on the standard of the finished product. These include bright polishing, annealing, and surface printing for traceability. Finally, all products are test certified, as required by their appropriate standard.

AISI 304 SS Pipes ANSI/ASME B36.19M 2004

The table shows our production programme within the ANSI B36.19 standard.

Selected ANSI-dimensions are stocked in following grades: 304/304L, 316/316L, UNS S31803 and UNS S31254/254 SMO®. See tables on following pages.

The design pressures are calculated in bar according to: ASME B31.3, ASTM A312 pipes with NPS 3/8"–24" SCH 10S and 40S. Steel grade is 304L, T = 38 °C (100 °F), joint quality factor Ej = 0.8.
