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:
