Dimensional Tolerances
The ASME code has surprisingly few dimensional tolerances. In fact, in section U-5, the Code states that tolerances are not fully addressed, and allowable tolerances should be based on engineering…
Heat Exchanger Fouling
Over time in service, deposits typically build up on the surface of tubes in a heat exchanger. This buildup is known as fouling and can occur on the inside or outside…
