It is equipment that does not have major moving or rotating parts (unlike pumps or compressors) and is used to contain or transfer process fluids. Hydrogen atoms diffuse into steel and recombine at

HIC occurs in carbon steel exposed to wet H₂S (sour service). Hydrogen atoms diffuse into steel and recombine at inclusions, creating internal cracks. Prevention:

It is a factor that reduces the allowable stress based on the weld quality. It depends on the type of weld (butt, fillet) and the degree of Non-Destructive Examination (NDE) performed (Full RT vs Spot RT).
