Corrosion Resistant Welded And Seamless Stainless Steel Pipes

Stainless steel pipe can generally be defined as a heavy wall thickness tubing, with dimensions as specified by the American National Standards Institute (ANSI). Pipe dimensions are nominated by outside diameter indicated by the NPS (imperial) or DN (metric) designator and sometimes referred to as the a nominal borea a and wall thickness, is determined by the schedule number. The standard ASME B36.19 covers these dimensions. Stainless steel pipe and fittings are supplied in the annealed condition to facilitate fabrication and ensure best corrosion resistance.Madhukar Steels can also supply stainless steel pipe with an abrasive polished finish suitable for architectural applications.

Welded pipe
Welded stainless steel pipe is manufactured from 2B or HRAP stainless steel strip a formed (to shape) and longitudinally welded to completed pipe. With the exception of very large pipe welds are made without the addition of filler metal. Standard welded pipe is in nominal lengths of 6.0 to 6.1 metres.

Manufacturing specification:
ASTM A312M Austenitic
ASTM A358M Austenitic (large diameter)
ASTM A790M Duplex.

Seamless Pipe
Seamless stainless steel pipe is produced from hollow billets, which are then drawn across dies until they reach the final desired pipe size and wall thickness. Standard seamless pipe is in random lengths of 6.0 to 7.5 metres.
