The calculation Formula for the Pressure of Ss Pipe
How to Calculate the Pressure of Ss Pipe:
1. Calculation formula: 2*wall thickness*(tensile strength*40%)/outer diameter
2. 316, 316L, TP316, TP316L-tensile strength: 485MA
3. 321, 304, 304L-tensile strength: 520MA
The tensile strength of 304 stainless steel pipe is 520MPA
The tensile strength of 316 stainless steel pipe is 485MPA
The water pressure that the ss pipe can withstand is not the same as the pressure value of different materials; the outer diameter and wall thickness are also very important factors. The thicker the wall thickness, the greater the pressure value it can withstand, such as the same outer diameter. 10 thick stainless steel pipes can withstand much higher water pressure than 5 thick stainless steel pipes; in addition, it is also related to the outer diameter. The larger the outer diameter, the smaller the pressure value it can withstand, such as the same wall thickness. , The larger the outer diameter, the smaller the pressure value it can bear;
The Calculation Formula for the Pressure of Ss Pipe:
Hydraulic test pressure: P=2SR/D
S means wall thickness, r means 40% of tensile strength, D means outer diameter;
The Following Example Illustrates:
304 stainless steel pipe specifications: 159*3
P=2*520*0.4*3/159=7.84MPA
316 stainless steel pipe specifications: 159*3
P=2*485*0.4*3/159=7.32MPA
