The Fluid Controls Institute (FCI) updated American National Standards Institute standard ANSI/FCI 87-1, Classification and Operating Principles of Steam Traps. It now includes three important information sections:

  • A calculation method for estimating cold versus hot condensate flow through different orifice shapes of long versus short internal orifice passageways.
  • Explains the differences between various steam trap designs.
  • Shows how condensate volumetric change after discharge may vary from 0 percent to over 216 times the original size, which is extremely useful for sizing condensate return lines with the required back pressure.

FCI also updated standard FCI 85-1, Standard for Production and Performance Testing of Steam Traps.  It was developed to assist manufacturers, users and specifiers of the products to comply with production and performance characteristics of automatic steam traps. These tests may be conducted to ensure the correct functioning of a steam trap or to evaluate the performance of particular designs, either currently in production or under consideration for production.

FCI is a non-profit trade association with the primary focus to develop national standards that promote better products of higher quality and greater usefulness. FCI creates and maintains globally recognized standards for classifying seat leakage through control valves and regulators, ANSI/FCI 70-2 and 70-3.
