Boiler Steel Pipe

Description

Boiler Steel Pipe is one of the important components of the boiler. It not only has an important impact on the safe and economical operation of the boiler, but is also an important standard for inspecting and evaluating the quality of the boiler. We can produce and supply high-quality boiler pipes and look forward to your arrival. .

Product Description

Boiler tubes refer to steel materials that are open at both ends and have hollow sections with a large length relative to the surrounding area. According to the production method, they can be divided into seamless steel pipes and welded steel pipes. The specifications of the steel pipes are determined by the external dimensions (such as outer diameter or side length) and Wall thickness is expressed in a wide range of sizes, from capillary tubes with very small diameters to large diameter tubes with diameters of several meters. Steel pipes can be used in pipelines, thermal equipment, machinery industry, petroleum geological exploration, containers, chemical industry and special purposes.
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) In addition to ensuring the chemical composition and mechanical properties of the commonly used 1Cr18Ni9 and 1Cr18Ni11Nb boiler tubes made of rusty heat-resistant steel, they must also undergo hydraulic tests, expansion and flattening tests one by one. Steel pipes are delivered in heat treated condition.
