Hollow Structural Carbon Steel Seamless Tube For Conveying Oil / Natural Gas
Specifications:
Fluid pipe is a hollow cross section, from the beginning to the end of the pipe without weld. The steel pipe has a hollow section, which is used for conveying oil, natural gas, gas, water and some solid materials. Compared to such as steel pipe and solid bar of steel, in flexural torsional strength are the same, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automobile transmission shaft, self frame as well as the construction of the steel scaffolding.

Description:
Compression algorithm:
One: in order to know the seamless steel pipe diameter wall thickness of seamless steel pipe diameter can bear the pressure calculation method (steel pipe of different material tensile strength is different)
Pressure = (wall thickness *2* steel pipe material tensile strength) / (outer diameter * coefficient)
Two: to know the seamless steel pipe diameter and the bearing pressure of the wall thickness calculation method:
Wall thickness = (pressure * coefficient) / (2* steel)
Three: steel pipe pressure coefficient representation method:
Pressure P<7Mpa coefficient S=8
7< S=6 coefficient P<17.5
Pressure P>17.5 coefficient S=4
