Can anyone give pipe wall thickness calculation with some examples?

Question

for eg

4" pipe od =114

pressure=51barg

temperature=300deg c

stress=18.2

y=0.4

e=1

please give the calculation for this example also can or you guys give the calculatio with some example also can

Answer 1

Any good pipe manufacturing company will provide you the applicable specifications for any commercial pipes with its engineering schedule data - it also depends upon the piping material type and grade etc.

Piping usage also depends upon application - process piping, boiler & pressure vessel piping, petrochemical industry piping etc.

Application suitability - pressure, temperature, corrosion etc.

*The overall formula used by ASME B31.3 for pressure design minimum thickness determination  is:

t =P* Do / 2 (S* E * P* y)

T=51*114/2*18.2*1*51*0.4)

T=7.82 MM

tm= t * A

tm=7.82*2

tm=15.65 MM

Add corrosion allowance=3 mm

tm=18.65 mm

*Pipe O.D (mm.) 114

Internal Design Pressure (barg) 51

Stress Value for Mat'l from Table A-1 (N/mm2) 18.2

Quality Factor ,E 1

Corrosion Allowance (mm) 3.00

Coefficient,Y (mm) 0.4

*Minimum pipe wall thickness=19.8
