Product Description
Boiler tubes are open at both ends and have a hollow section. Boiler tubes are a type of seamless tubes. 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. According to the use temperature, it is divided into two types: general boiler tube and high pressure boiler tube.
Steel Grade
(1) The steel grades of high-quality carbon structural steel are 20G, 20MnG, and 25MnG.
(2) Alloy structural steel Steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.
(3) 1Cr18Ni9 and 1Cr18Ni11Nb boiler tubes commonly used in rusty and heat-resistant steels must be subjected to hydrostatic tests one by one, flaring and flattening tests in addition to ensuring chemical composition and mechanical properties. Steel pipes are delivered in a heat-treated state.
In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe.
