Sep 21, 2020 · The boiler tube is a kind of seamless tube. The manufacturing method is the same as that of seamless steel pipes, but there are strict requirements on the steel grades used in the manufacture of steel pipes. According to the operating temperature, it can be divided into general boiler tubes and high-pressure boiler tubes. Seamless steel pipes for high temperature and pressure serviceHigh pressure seamless steel quality should by steel pipe factory to make a guarantee, but in the case of short supply, the use of high-pressure supplied to the boiler manufacturers seamless steel pipe always found some quality problems, it made boiler pressure components such as water wall tubes, convection tubes, superheater tubes, heat exchanger tubes leaking or burst pipes phenomenon have occurred, has become a big problem that plagued boiler product quality, this boiler seamless steel pipe ASTM_CHN Steel pipe & tube Co.Seamless steel tubes for. oil casing and. tubing in oil wells.
