After that, the actual pipe thickness is selected (immediate higher size thickness of the calculated value) from ASME code tables depending on pipe material (CS or SS). After the calculation of minimum wall thickness, corrosion and mechanical allowances need to be added to that. The major parameters involved in thickness calculation are Design pressure, Pipe OD, and Allowable Stress at design temperature. All codes (B 31.3, B 31.1, IBR, B 31.4, B 31.8, nuclear code, etc.) provide equations for calculating the minimum wall thickness based on the pressure that the pipe has to withstand. The calculation of wall thickness varies depending on the usage of the code. Pipe Schedule / Pipe wall Thickness Calculation Pipe of sizes and wall thicknesses other than those of Standard, Extra-Strong, and Double Extra-Strong, and Schedule Number were adopted from API Specification 5L. With an increase in pipe thickness internal diameter of the pipe reduces as the pipe’s outer diameter remains constant.

The double Extra Strong (XXS) wall is thicker than SCH 160 from NPS 1/8 to NPS 6, and SCH 160 is thicker than the XXS wall for NPS 8 and larger.All larger sizes of Extra-Strong have 12.70 mm wall thicknesses. Extra-Strong (XS) is identical to SCH 80 up to NPS 8.All larger sizes of Standard (STD Schedule) have 9.53 mm wall thicknesses. Standard (STD) is identical to SCH 40 up to NPS 10.
