Bursting Pressure

Barlows Formula and bursting pressure of pipes and tubes

Sponsored Links

Barlow's formula can be used to estimate burst pressure of pipes or tubes.

P = 2 s t / ((do - 2 t) SF)         (1)

where

P = max. working pressure (psig)

s = material strength (psi)

t = wall thickness (in)

do = outside diameter (in)

SF = safety factor (in general 1.5 to 10)

The Barlow's estimate is based on ideal conditions at room temperature.

Material Strength

The strength of a material is determined by the tension test, which measure the tension force and the deformation of the test specimen.

Strength of some common materials:

Material Yield Strength
(psi)
Ultimate Strength
(psi)
Stainless Steel, 304 30,000 75,000
6 Moly, S31254 45,000 98,000
Duplex, S31803 65,000 90,000
Nickel, N02200 15,000 55,000
