Pipe Thickness Calculation as per ASME B31.3 | Pipe Thickness Calculator
🔥🔥
Pipe wall thickness calculation is one of the important basic activities for every piping engineer. Process plants deal with the fluids which flow inside the pipe at high pressure and temperature. So, the pipe deals with high circumferential pressure which can cause the bursting of the pipe if the pipe thickness is not enough. Hence, The designers need to find out the required piping thickness as per section “304.1.2 of ASME B31.3” to resist the internal line pressure. The operation must be leak-free.

Why is Pipe Thickness Calculation Important?🔥🔥
The minimum required thickness of a pipe must be calculated to ensure
The selected pipe will be able to withstand the pressure at the design temperature without failure.
To avoid being over conservative and thus optimize cost.
Few Important Points required for Pipe thickness Calculation
Before starting the piping thickness calculation, the engineer should be aware of the following points:
Process plants are designed for 20 years or 7200 cycles. (Considering 1 cycle per day; Total number of cycles in 20 years=20*360=7200 cycles)
Pressure and temperature can vary from line to line and from time to time.
Fluid could be corrosive and toxic in the system.
Corrosion allowance for pipe material is decided based on service fluid. Typical values are 3 mm for Carbon Steel and zero mm for stainless steel.
Mill tolerance for the seamless pipe is 12.50% and 0.3 for the welded pipe.🔥🔥
