Folded Brinell hardness:
Among the stainless steel pipe standards, Brinell hardness is the most widely used, and the hardness of the material is often expressed by the indentation diameter, which is both intuitive and convenient. But it is not suitable for steel pipes of harder or thinner steel.
Folded Rockwell hardness:
The Rockwell hardness test of stainless steel pipe is the same as the Brinell hardness test, which is the indentation test method. The difference is that it measures the depth of the indentation. Rockwell hardness test is currently a widely used method, among which HRC is second only to Brinell hardness HB in steel pipe standards. Rockwell hardness can be used to measure metal materials from extremely soft to extremely hard. It makes up for the difference of the Brinell method and is simpler than the Brinell method. The hardness value can be read directly from the dial of the hardness machine. However, due to its small indentation, the hardness value is not as accurate as the Brinell method.
Folded Vickers hardness:
The stainless steel tube Vickers hardness test is also an indentation test method, which can be used to determine the hardness of very thin metal materials and surface layers. It has the main advantages of Brinell and Rockwell method, and overcomes their basic shortcomings, but it is not as simple as Rockwell method. Vickers method is rarely used in steel pipe standards.
 

Chemical Composition

 

Weight calculation:
Hydraulic test pressure formula of stainless steel welded pipe for fluid (GB/T1277-2008):
P=2RS/D
Where: P-test pressure, MPa;
R-stress, take 50% of yield point, MPa;
S-Nominal wall thickness of steel pipe, mm;
D- the nominal outer diameter of the steel pipe, mm.
W=(outer diameter-wall thickness)×wall thickness×0.02491=KG/M (weight per meter).

Application

Stainless steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, machinery and instrumentation and other industrial pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. It is also often used as furniture and kitchen utensils.
