ASTM A179 covers minimum wall thickness, seamless cold drawn low carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. There are other steel grades for heat exchanger application such as 20G smls pipe, ASTM SA106B/C boiler steel pipe and ASTM SA210A/C high temperature boiler tubes.

Boiler steel tube is open on both ends and has a hollow section, the length and the surrounding of the larger steel, according to the production methods can be divided into seamless boiler steel pipe and welded steel pipe. Heat exchanger boiler steel pipe specification with overall dimensions (such as the diameter or length) and the wall thickness and said the size range of boiler steel pipe is very wide from small diameter capillary until several meters in diameter with large diameter pipe. Heat exchanger boiler steel pipe can be used in the pipeline, thermal technology equipment, industrial machinery, petroleum geological exploration, containers, chemical industry and other special purposes. According to the cross section shape and can be divided into circular tube and special-shaped heat exchanger steel tube which is widely used, but there are some square, rectangle, semicircle, hexagonal, equilateral triangle, octagonal special-shaped steel tube. For fluid under pressure boiler steel pipe are hydraulic experiment was carried out to test the compression ability and the quality, under the pressure of regulation does not leak, soaked or expansion of qualified. Some boiler steel pipe according to the standard or the buyer requires edge test, flaring test and flattening test etc.
Application for boiler steel pipe is widely used in Water wall tube, water pipe, superheated steam tube, locomotive boiler superheated steam pipe, large and small pipe and tube arch brick, etc.
