Seamless pipe is a kind of Strip steel, Which mainly used for transport gas and water and other solid material, Comparing with other steel pipe, it is more lighter weight when same tending strength, meanwhile, as different pipe size, It be divide into two manufacture processing.
1.Weldable
2.Low Carbon Steel with high strength
3.Withstand High Pressure
4.No Welding Line or Joints
With all of the features, the carbon seamless steel pipes are applied in a lot of high-pressure equipment and lines. Like refineries, hydraulic cylinders, hydrocarbon, oil gas infrastructures, etc.
In the tensile process, the maximum force (Fb) that the sample bears when it breaks is the stress (σ) obtained from the original cross-sectional area (So) of the sample, which is called the tensile strength (σb), and the unit is N/mm2 (MPa). It represents the maximum ability of a metal material to resist damage under tensile force.
For a metal material with a yield phenomenon, the stress at which the sample can continue to elong without an increase in the force during the stretching process (remains constant) is called the yield point. If the force drops, the upper and lower yield points should be distinguished. The unit of yield point is N/mm2 (MPa).
In the tensile test, the percentage of the length of the gauge length increased after the sample is broken to the original gauge length is called the elongation. Expressed by σ, the unit is %.
