High pressure boiler steel pipe applications, grades and profiles!

November 05,2022

High-pressure  Boiler Steel Pipe  :

 mainly used to manufacture high-pressure and above-pressure steam boiler pipeline with high-quality carbon structural steel, alloy structural steel and stainless heat-resistant steel  Seamless Steel Pipe, these boiler tubes are often at high temperature and high pressure work, the tube in the role of high-temperature flue gas and water vapor will also be oxidation and corrosion, so the steel pipe is required to have high lasting strength, high oxidation resistance, and has good organizational Stability, the use of steel grades are: high-quality carbon structural steel grades 20G, 20MnG, 25MnG; alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.; rust heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb 1Cr18Ni11Nb high-pressure boiler tube in addition to ensure the chemical composition and mechanical properties, to do the hydraulic test one by one, to make the flaring, flattening test.

Steel tube to heat treatment state delivery.

In addition, the finished steel pipe microstructure, grain size, decarburization layer also has certain requirements.
