Note:

PIPE THICKNESS CALCULATION AS PER ASME B31.3

ASTM A333 Gr.6 (Seamless)

Note:

1. Pipe thickness is selected based on Minus Tolerance for the Pipe Selected Thickness i.e. (Used thickness - Mill Tolerance @ 12.5%) > Minimum required Thickness.

2. Low carbon steel material shall be provided with 3 mm CRA cladding.
