15CrMo alloy Steel Pipe Application
Application For high, middle, low pressure boiler and pressure purpose 15CrMoG alloy tube of the principles of the purified hydrogen at 300-500 ℃, the hydrogen to be purified is passed through one side of the 15CrMoG alloy tube, the hydrogen is adsorbed on 15CrMoG alloy wall, palladium 4d electron shell lacks two electronics, it can with the hydrogen generating unstable chemical bonds (palladium and hydrogen, this reaction is reversible), palladium, hydrogen is ionized proton whose radius is 1.5 × 1015m, while the lattice constant of palladium 3.88x 10-10M (20 ° C time), it can be through 15CrMoG alloy tube role of palladium proton combined with electronic and re-formation of the hydrogen molecules to escape from the other side of the 15CrMoG alloy tube.15CrMo alloy Steel Pipe Manufacturing Process
1. Process Procedure: Because of alloy pipes’ different manufacturing processes, they are divided into hot-rolled (extrusion) seamless and cold drawn (rolled) Seamless two. Cold drawn (rolled) pipe is divided into circular pipe and shaped pipe. 2. 15CrMo alloy tube Process Overview: a. rolled (extrusion seamless): ro und tube perforation → heating → three-roll rolling, rolling or extrusion → detached → sizing (or reducing) → cooling → billet tube → straightening → hydrostatic test (or testing) → mark → storage. b. cold drawn (rolled) seamless steel pipe: round perforated tube → heating→ annealing → pickling → Heading oiled (copper) → multi-pass cold drawn (rolled) → heat treatment → straightening pipe billet straight → hydrostatic test (testing) → mark → storage. 15CrMo alloy pipe is one kind of seamless steel pipe, and its performance is much higher than the average of seamless steel tubes, because the steel contains Cr more inside. It can bear high temperature, and corrosion is better than other seamless pipes performance, so alloy tube is more widely in the petroleum, chemical, electric power, boiler and other industries.
