The strength of a material is determined by the tension test which measure the tension force and the deformation of the test specimen.
Typical strength of some common materials:
Material | Yield Strength (psi) | Ultimate (Tensile) Strength (psi) |
---|---|---|
Stainless Steel, 304 | 30000 | 75000 |
6 Moly, S31254 | 45000 | 98000 |
Duplex, S31803 | 65000 | 90000 |
Nickel, N02200 | 15000 | 55000 |
A53 Seamless and Welded Standard Pipe, Grade A | 30000 | 48000 |
A53 Seamless and Welded Standard Pipe, Grade B | 35000 | 60000 |
The Barlow's formula calculator can be used to estimate
The Barlow's formula calculator can be used to estimate minimum wall thickness of pipe.
Bursting pressure calculated with Barlow's formula (2) for A53 Seamless and Welded Standard Pipe Grade A with ultimate (tensile) strength 48000 psi. Pipe dimensions - outside diameter and wall thickness according ANSI B36.10.
