The ASTM A178 standard refers to the minimum wall thickness of electric resistance welded pipes, which are made of carbon steel and carbon manganese steel. Boiler tubes, boiler flues, superheater flues, and safety ends are all made of ASTM A178 pipes, with steel grades A (low carbon steel), C (medium carbon steel) or D (carbon manganese steel). The manufacturing process must include heat treatment, cooling and welding. If required by the customer, a crush test can be performed.
ASTM A178 condenser steel pipe is a special steel pipe for condensers, mainly used to manufacture condensing equipment. Condensers are devices that convert gas or steam into liquid. They are usually used in refrigeration, air conditioning, chemical industry and other fields.
