High Pressure Boiler Tube Seamless Boiler Steel Pipes

Description

Video Description

Boiler tubes are a type of seamless tubes. The manufacturing method is the same as that of seamless steel pipes, but there are strict requirements on the steel types used in the manufacture of steel pipes. According to the use temperature, it is divided into two types: general boiler tube and high pressure boiler tube.
1. General boiler tubing 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.
2. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, air guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.
In addition to ensuring the chemical composition and mechanical properties of boiler steel pipes, hydrostatic tests, flaring and flattening tests are required one by one. Steel tubes are delivered in a heat-treated state.
