Pipes

Undersized pipes create large pressure drops and high velocities, whilst oversized pipes are unnecessary and costly. This calculator allows steam and condensate pipes to be sized correctly. Steam pipes can be sized on pressure drop and velocity, and up to three steam trap discharge lines and associated common lines can be sized. Discharge lines from mechanical and electrical condensate pumps can also be sized.

Steam

  • Sizing New Pipes - Design new steam pipes correctly on pressure drop and velocity methods.

  • Checking Existing Pipes - The capacity of existing pipework can be checked using pressure drop and velocity methods, and the maximum steam flow can be determined for the chosen sized pipe.

  • Start Up & Running Losses - For any steam main, determine the appropriate size of warm-up valve and number of steam traps, in line with good practice.

Condensate

  • Single Discharge Line - Size a steam trap discharge line based on condensate and flash steam flow.

  • Two Discharge Lines - Size the discharge lines from two steam traps plus the associated common line based on condensate and flash steam flow.

  • Three Discharge Lines - Size the discharge lines from three steam traps plus the associated common lines based on condensate and flash steam flow.

  • Pumped Return Lines - Size the pump discharge line from a mechanical or electrical condensate pump to the downstream condensate system.
