Because of various assembling forms, consistent steel cylinders are separated into hot-rolled (working) consistent steel cylinders and cold drawn (rolled) consistent steel tubes. The chilly drawn (moved) containers of butt-welded elbows are isolated into round cylinders and Shaped cylinder two stainless steel seamless pipe. Hot-moved consistent steel pipe (plying consistent steel pipe): round cylinder clear → warming → puncturing → three-move cross-rolling, ceaseless rolling or working → pipe expulsion → estimating (or diminishing distance across) → cooling → Blank cylinder → fixing → water driven test (or defect discovery) → logo mark → storage.
The key is utilized for a similar day by day arranging machine structure. Its delegate material (signature): carbon steel 20, 45 steel; combination steel Q345, 20Cr, 40Cr, 20CrMo, 30-35CrMo, 42CrMo, and so on. Key for building and years old Type gear and hardware are orchestrated on the vehicle liquid pipeline. The delegate material (signature) is 20, Q345, and so forth. The high weight spine is for the most part utilized for the riches heater and the evaporator to move the low and medium weight liquid. The agent material is 10, 20 steel.
consistent steel pipe maker
The level welding rib is for the most part utilized for high temperature and high weight transportation of liquid gathering boxes and pipelines on power stations and atomic power plant boilers. The agent materials are 20G, 12Cr1MoVG, 15CrMoG, and so forth. The key is utilized for I, II weight channels for ship boilers and superheaters. The agent material is 360, 410, 460 steel evaluation and other key utilized in manure gear and hardware to ship high temperature and high weight liquid pipeline. Delegate materials are 20, 16Mn, 12CrMo, 12Cr2Mo thus on.1 1 4 timetable 40 hardened steel pipe provider
The key is utilized in boilers of oil smelters, warm communicators and their vehicle liquid pipelines. The agent materials are 20,12CrMo, 1Cr5Mo, 1Cr19Ni11Nb, and so on. The key is to make different gas and water driven chambers. The delegate materials are 37Mn, 34Mn2V. , 35CrMo, and so forth. The key is to make coal mineshaft water driven backings and chambers, sections, and other pressure driven chambers, segments. The delegate material is 20, 45, 27SiMn, etc.
