ASTM A179 Boiler Tube ASTM A179 is an American standard, cold drawn seamless mild steel heat exchanger and condenser tube. Boiler Steel Pipe/tube is a kind of Seamless Steel Pipe. The manufacturing method is the same as Seamless Steel Pipes, but there are strict requirements on the steel grades used to manufacture Boiler Steel Pipes. According to the temperature, it is divided into two types of low-pressure boiler tubes and high-pressure boiler tubes. The mechanical properties of boiler tubes are an important indicator to ensure the properties (mechanical properties) of the end-use steel. It depends on the chemical composition of the steel and the heat treatment system. In the Steel Pipe standard, according to different application requirements, tensile properties (tensile strength, yield strength or yield point, elongation), hardness and toughness indexes, as well as high and low temperature properties required by users are specified.
