Product Description
Products Information Large diameter
Seamless Pipe in China at present, the main production process for hot rolling of large diameter
Seamless Steel Tube and thermal expansion diameter seamless steel tube, the maximum thermal expansion of seamless steel tube specifications for 325 mm - 1220 mm the thickness is 1220 mm.Large diameter seamless pipe in China at present, the main production process for hot rolling of large diameter seamless steel tube and thermal expansion diameter seamless steel tube, the maximum thermal expansion of seamless steel tube specifications for 325 mm - 1220 mm to 120 mm, the thickest thermal expansion can produce the gb size seamless steel tube, thermal expansion of seamless pipe is we often say that the heat expansion, density is lower but strong contraction of steel tube with method of skew rolling or drawing method to expand the pipe diameter of a waste pipe finishing process.In a relatively short period of time to make
Steel Pipe enlargement, can produce non-standard, special types of
Seamless Tube, and low cost, high production efficiency, is the international development trend in the field of tube rolling. Large-diameter seamless steel tube after cold drawing and cold rolling cold forming steel, direct delivery without any heat treatment state, known as the cold drawn or cold rolled condition.Compared with the state of hot rolling, forging, cold drawing (rolling) state of high dimensional accuracy, good surface quality of steel, the surface roughness is low, and have higher mechanical properties, because of cold drawing (rolling) status of the delivery of steel surface without oxidation skin coverage, and there are a lot of stress, vulnerable to corrosion or rust, so cold drawing (rolling) of the state of the steel, its packaging, storage and transportation are more strict requirements, generally must be within the warehouse storage, and should pay attention to the temperature and humidity control within the warehouse.
