4.3

ALLOWABLE STRESS VALUE Allowable stress values are referred from applicable design codes for respective piping class: • Platform Process Piping: Table A-1 of ASME B31.3 • Gas Transportation Pipeline: Appendix D of ASME B31.8 • Pipeline Transportation System for Liquid: Table 402.3.1(a) of ASME B31.4 These values have been used for pipe wall thickness calculation.

4.4

CORROSION ALLOWANCE (CA) Corrosion allowance (CA) based on piping class is used as applicable.

4.5

EROSION ALLOWANCE Erosion allowance as stated in piping class is used as applicable.

4.6

MECHANICAL ALLOWANCE (C) Mechanical allowances are sum of corrosion allowance, erosion allowance, any other mechanical allowance and threading allowance.

4.7

MILL TOLERANCE Mill tolerance has been considered as (-)12.5% for Seamless Pipes & Welded (with 100% RT) pipes.

5.

METHODOLOGY a) Pipe Wall Thickness Calculation as per ASME B31.3 The formula for metallic pipe is as follows : PD (ASME B31.3 para. 304.1.2) t= (when t is less then D/6; or D/t > 6) 2( SEW + PY ) tm = t + c T' = (T" x (1.00 - MT)) (wall thickness selection validity; T' > tm ; ASME B31.3 Appendix S para. S301.2) The formula for GRE pipe is as follows : PD (ASME B31.3 para. A304.1.1)

t=

( 2 SF + P )

tm = t + c t tm c MT T" T' P D S E Y W F

= pressure design thickness (mm) = minimum required thickness plus corrosion, mechanical and erosion allowance (mm) = sum of mechanical allowances. (mm) (corrosion, erosion & threading allowances). = factor to account mill tolerance on pipe wall thickness. (0.125 for seamless pipes and welded pipes) = selected wall thickness = wall thickness after deducting mill tolerance from T" = internal design pressure (bar) for calculation purpose converted to MPa. = outside diameter of pipe (mm) = basic allowable stress for the material = quality factor, as per table A-1A or A-1B of ASME B31.3. = co-efficient, as per table 304.1.1 of ASME B31.3. = weld joint strength reduction factor, as per para. 302.3.5(e) of ASME B31.3. = Service (design) factor, as per para. A302.3.2(c)

EXCEPTIONS Pipes with sizes 1/4”, 11/4”, 21/4”, 31/2”, 5”, 7”, 9” and 22” shall not be used unless required by equipment connections. For non-standard pipe size, the pipe wall thickness calculation should be calculated as per case basis.

PIPE WALL THICKNESS CALCULATION Following sections cover the pipe wall thickness calculations.The 'Sch' gives the minimum selected schedule or wall thickness of pipe wall after the calculation. The pipe wall thicknesses are calculated in accordance with ASME B31.3 for topside piping, ASME B31.8 for topside gas pipeline and ASME B31.4 for topside liquid pipeline.
