Steel Tube Knowledge: Seamless Tubes for Boilers belong to the category of Seamless Steel Tubes

The boiler seamless pipe is a type of boiler pipe and belongs to the category of seamless steel pipes. The manufacturing method is the same as that for seamless pipes, but there are strict requirements for the steel grades used in the manufacture of steel pipes. Boiler seamless pipes are often used under high temperature and high pressure conditions. The pipes are subject to oxidation and corrosion under the effect of high-temperature flue gas and water vapor. The steel pipe is required to have high endurance strength, high oxidation corrosion resistance, and good organization stability. The boiler seamless pipe is mainly used to manufacture high pressure and pipe, main steam pipe and so on.
Boiler seamless pipe adopts steel number
(1) High-quality carbon structural steel grades are 20G, 20MnG, and 25MnG.
(2) Alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.
(3) The rust-resistant heat-resistant steel commonly used 1Cr18Ni9, 1Cr18Ni11Nb boiler tubes in addition to ensure chemical composition and mechanical properties, to do the hydrostatic pressure test by root, to be flaring, flattening test. The steel pipe is delivered in a heat-treated state.
In addition, there are certain requirements on the microstructure, grain size, and decarburization layer of the finished steel pipe.
