Stainless steel pipe stress how to calculate:
1, the calculation formula: 2 X wall thickness X (tensile strength X40 %)/outer diameter
2, 316, 316 l, TP316, TP316L - tensile strength: 485 ma
3, 321, 304, 304, l - tensile strength: 520 ma
The tensile strength of 304 stainless steel tube is 520 mpa
The tensile strength of 316 stainless steel tube is 485 mpa
And stainless steel pipe to withstand water pressure in addition to the material of different can withstand the pressure value is not the same size;Outer diameter and wall thickness is also very important factors, the wall thickness is thicker, can withstand the pressure value, the greater the same diameter, for example, 10 thick stainless steel tube is thicker than the five stainless steel tube can withstand the pressure is much higher;Is also related to the outer diameter, outside diameter is larger, can withstand the pressure value is smaller, such as the same wall thickness, outer diameter, the greater the can withstand the pressure value is smaller;
Stainless steel pipe under pressure calculation formula:
Hydrostatic test pressure: the P = 2sr/D
S refers to wall thickness, r refers to 40% of the tensile strength, D refers to the outer diameter;
The following example:
304 stainless steel pipe specification: 159 * 3
P = 3/159 * 520 * 0.4 * 2 = 7.84 MPA
316 stainless steel pipe specification: 159 * 3
P = 3/159 * 485 * 0.4 * 2 = 7.32 MPA
Stainless steel seamless tube different classification according to the requirement as follows:
According to the production process is divided into: stainless steel cold drawn tubes, stainless steel precision tube.
According to the cross section is divided into: stainless steel pipe, stainless steel square tube, stainless steel rectangular tubes, stainless steel section tube (a triangle tubes, hexagonal tubes, etc.)
According to the wall thickness can be divided into: thick wall stainless steel tubes, thin-walled stainless steel tube
According to the diameter can be divided into: large diameter stainless steel pipe, small diameter stainless steel pipe, stainless steel capillary
According to the search habits can be divided into: stainless steel seamless pipe, seamless stainless steel pipe, stainless steel pipe, stainless steel pipe, stainless steel seamless steel tube
By region can be divided into: dainan stainless steel pipe, stainless steel tube, taizhou in jiangsu stainless steel pipe, stainless steel pipe, stainless steel tube in zhejiang wenzhou, foshan, stainless steel pipe, stainless steel pipe, stainless steel pipe in Beijing, Shanghai shandong stainless steel pipe
According to stainless steel seamless tube material is divided into: 201, 202 stainless steel seamless tube, 301 stainless steel seamless tube, 304 stainless steel seamless tube, 316 l stainless steel seamless tube, 310 s stainless steel seamless tube.
