Large Diameter 4" Carbon Steel Seamless Pipe With API 5L / API 5CT / LR Certificates

Large Diameter 4" Carbon Steel Seamless Pipe With API 5L / API 5CT / LR Certificates

Specifications:

Parts with good mechanical properties are widely used in various important structural parts, especially those working under alternating loads. But the surface hardness is low, no wear resistance. Can be used to improve the surface hardness of the part of the quenching and tempering and surface hardening.

 Description:

45# is GB ,JIS named:S45C,ASTM named 1045,080M46,DIN called:C45

45# Chemical Component:C 0.42~0.50%,Si 0.17~0.37%,Mn 0.50~0.80%, Cr<=0.25%

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

Applications:
