High pressure boiler steel pipe

November 2, 2022

 

Steel tubes are delivered in a heat treated state. In addition, the microstructure, grain size and decarbonization layer of the finished steel pipe are also required.

 

Mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless heat resistant steel seamless steel tube, these often under high temperature and high pressure boiler tube, tube in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance, And has good organizational stability, in addition to ensure the chemical composition and mechanical properties of the high-pressure boiler tube, to do the hydraulic test root by root, to make flaring, flattening test.
