Seamless Boiler Tube

General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.

◉ Product Details


Boiler seamless steel pipe is a kind of seamless pipe. The manufacturing method is the same as that of the seamless pipe, but there are strict requirements on the steel type used in the manufacture of the steel pipe. Boiler seamless steel tubes are divided into general boiler tubes and high-pressure boiler tubes according to their high temperature performance. General boiler tubes or high-pressure boiler tubes can be divided into various steel tubes according to their different requirements.
