This part of the Pipemill program is intended for the design of large bore refinery type fittings where standard components may not be available:
Calculations are in accordance with ASME VIII B31.3 (line blinds, mitre elbows) and ASME VIII Div. 1 (2000) (end caps).
Pressure, temperature, allowable stress, corrosion allowance, mill tolerances, bend radius, etc.
Stress intensification factors are calculated for mitre elbows.
