Hot And Cold Performance Of Seamless Steel Pipe
Oct 23, 2017

In addition to the general steel pipe, low pressure boiler steel pipe, high pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, other steel pipe, but also includes carbon thin-walled steel pipe, alloy thin-walled steel pipe, Stainless steel pipe, shaped steel pipe. Hot-rolled seamless pipe diameter is generally greater than 32mm, wall thickness of 2.5-75mm, cold-rolled seamless pipe diameter can be 6mm, wall thickness to 0.25mm, thin-walled tube diameter to 5mm, wall thickness less than 0.25mm, Cold rolling than the hot-rolled high dimensional accuracy.Seamless Steel Pipe

Low and medium pressure boiler seamless steel pipe: for the manufacture of various low and medium pressure boilers, superheated steam pipes, boiling water pipes, water wall pipe and locomotive boiler with superheated steam pipe, smoke pipe, small smoke pipe and arch brick. Hot-rolled or cold-rolled (welded) seamless steel tubes with high quality carbon structural steels. Mainly made with 10,20 steel, in addition to ensuring the chemical composition and mechanical properties to do water pressure test, curling, flaring, flattening and other tests. Hot-rolled to hot-rolled delivery, cold-rolled (dial) to heat treatment delivery.Seamless Steel Pipe

Seamless Steel Tube for Geological Drilling and Oil Drilling: In order to test the structure of underground rock formation, groundwater, oil, natural gas and mineral resources, Oil and natural gas mining is more inseparable from drilling, geological drilling with oil drilling with seamless steel pipe is the main drilling equipment, including the core of the outer tube, core tube, casing, drill pipe and so on. As the drilling pipe to drill into the depth of several kilometers to work, the working conditions are extremely complex, the drill pipe to bear the pull, pressure, bending, torsion and uneven impact load and other stress, but also by the mud, rock wear and tear, therefore, Must have sufficient strength, hardness, wear resistance and impact toughness.Seamless Steel Pipe
