Weight calculation of stainless steel pipe

- Dec 09, 2018-

Hydraulic test pressure formula of stainless steel welded pipe for fluid (GB/T1277-2008):

P=2RS/D

In the formula: p-test pressure, MPa;

r-stress, take yield point 50%,mpa;

s-steel pipe nominal wall thickness, mm;

Nominal outer diameter of d-steel pipe, MM. w= (outer diameter-wall thickness) x wall thickness x0.02491=kg/m (weight per meter).
