Seamless Stainless Steel Tube/Pipe Boiler Tube Heat Exchanger Tube 20#45#
Structural Tubing is a hollow section most commonly constructed from hot rolled metal coils. The coils are slit to the proper width for the section being manufactured and then formed into the final shape needed. Once the size is formed and the seams are welded together the tube is cut to the desired length to make a single piece of tubing. Structural tubing is offered in round, rectangular and square shapes.

Application:
① General boiler seamless pipes are mainly used to make water wall pipes, boiling water pipes, superheated steam pipes, superheated steam pipes for locomotive boilers, large and small smoke pipes and arched brick pipes.
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.
Boiler seamless steel tube adopts steel grade:
(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 commonly used 1Cr18Ni9 and 1Cr18Ni11Nb boiler tubes with rust and heat-resistant steels should be subjected to hydrostatic tests, flaring and flattening tests one by one in addition to ensuring chemical composition and mechanical properties. Steel pipes are delivered in heat-treated condition.
