Construction

ASTM A249 is a standard specification for welded austenitic stainless steel tubes for boilers, superheaters, heat exchangers, and condensers.

S355JOW belongs to the European standard weather-resistant steel pipe. Weather-resistant structural steel is atmospheric corrosion-resistant steel and is a low-alloy high-strength structural steel.

The ASTM A671 Grade CC60 Class 22 pipes have wall thicknesses up to 250mm and are from 5m to 13m length with single random, double random and cut to length sizes.

The specification covers grades of stainless steel tubing for general corrosion-resisting and low or high-temperature service.
