Stamping Technology Of Seamless Steel Pipe
Nov 01, 2017

Cold-rolled (dial) seamless steel pipe In addition to the general steel tube, low pressure boiler steel pipe, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, petroleum cracking pipe, other steel pipes, but also include carbon thin-walled steel pipe, alloy thin-walled steel pipe, stainless steel thin-walled pipe, profiled steel Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness 2.5-75mm, cold rolled seamless steel pipe diameter can be 6mm, wall thickness can be to 0.25mm, thin-walled tube diameter can be to 5mm, wall thickness is less than 0.25mm, cold rolling than hot-rolled size precision high.Seamless Steel Pipe

Low-medium pressure boiler seamless steel tube: Used for manufacturing all kinds of low medium pressure boilers, superheated steam pipes, boiling water pipes, water-cooled wall tubes and locomotive boilers with superheated steam pipes, opium pipes, small smoke pipes and arch brick pipe. High-quality carbon structural steel hot-rolled or cold-rolled (dial) seamless steel tube. The main use of 10, 20th steel manufacturing, in addition to ensure chemical composition and mechanical properties to do water pressure test, curling, expanding, flattening and other tests. Hot-rolled in hot-rolled state delivery, cold rolling (dial) in the state of heat delivery.Seamless Steel Pipe

Seamless steel tubes for geological drilling and oil drilling: to ascertain the structure of underground rock strata, groundwater, oil, natural gas and mineral resources, drilling rig. Oil, natural gas mining more inseparable from drilling, geological drilling with the oil drilling seamless steel pipe is the main equipment, mainly including core outer tube, core inner tube, casing, drill pipe and so on. Because the drilling pipe should be deep to the depth of thousands of meters, the working conditions are extremely complex, and the drill pipe is subjected to tensile, compressive, bending, torsion and unbalanced impact loads.Seamless Steel Pipe

The steel pipe is delivered under heat treatment condition. Stainless steel pipe: With a variety of stainless steel hot-rolled, cold-rolled stainless steel pipe, widely used in petroleum, chemical equipment pipelines and various uses of stainless steel structural parts, in addition to ensure that chemical composition and mechanical properties, where used to withstand fluid pressure of the steel pipe to ensure that water pressure test qualified. All kinds of special steel pipe should be guaranteed under the conditions.Seamless Steel Pipe
