Application and Introduction of Boiler Tube
Boiler tubes are divided into general boiler tubes and high-pressure boiler tubes according to the high-temperature performance they withstand. The gernal boiler tube and high-pressure boiler tube can be divided into various steel tubes according to their different requirements. Specification and Appearance (1) GB3087-2008 "Seamless Steel Tubes for Low and Medium Pressure Boilers". The specifications of steel tubes for boilers of various structures, with an outer diameter of 10 ~ 426mm, a total of 43 kinds. A total of 29 kinds of wall thickness 1.5 ~ 26mm. However, the outer diameter and wall thickness of the superheated steam pipe, large smoke pipe, small smoke pipe and arch brick pipe for locomotive boilers are otherwise specified. (2) GB5310-2008 "Seamless steel tubes for high-pressure boilers" hot-rolled tubes have an outer diameter of 22 ~ 530mm and a wall thickness of 20 ~ 70mm. The cold drawn (cold rolled) tube has an outer diameter of 10 ~ 108mm a...
