STEAM TRAPS & PIPELINE ACCESSORIES

Thermodynamic Steam Trap

WORKING PRINCIPLE

Thermodynamic steam trap operates on the principle of thermodynamic and fluid dynamics. They utilise the heat energy of hot condensate and the kinetic energy in the steam to open and close.

FEATURES
  • Thermodynamic steam trap is complete stainless steel internals ensure better mechanical & corrosion resistance properties.
  • Condensate entry below the disc, concentric to the disc/seat ensures a clean & parallel lift of the disc with reference to the seat, eliminating localized wear & tear.
  • The disc & seat are fully hardened by a special hardening process, to withstand continuous, prolonged operation.
  • Perfect shut off, no steam loss.
  • Thermodynamic steam trap is robust, maintenance free, fully guaranteed.

INSTALLATION

Thermodynamic steam trap will operate in any position but the preferred installation is in a horizontal position with the disc seat cover on top. Full port isolating valves should be installed upstream and downstream of the trap.

MAINTENANCE

  • Thermodynamic steam trap can be maintained without disturbing the piping connections. Ensure that the trap is isolated – upstream and downstream – before attempting to dismantle it. ALLOW THE TRAP TO COOL BEFORE DISMANTLING.
  • For trouble-free performance, periodic cleaning of the disc, seat and strainer screen is recommended.
  • Do not use abrasive/corrosive media for cleaning. Only the disc and seat are subject to wear. A worn disc can be replaced. Slight seat wear can often be corrected by resurfacing on a lap plate.

ADVANTAGES
  • Thermodynamic steam trap is Simple, small and light construction
  • It can be mounted in any position
  • Thermodynamic steam trap is Rugged, not affected by water hammer
  • Operate over a wide pressure range
  • Follow the steam saturation curve
  • Performance of thermodynamic steam trap easy to check
  • Primary failure mode – open
IMPORTANT NOTE
  • Thermodynamic steam trap should be installed as close as possible to the line to be drained.
  • For new pipelines, ensure that the lines are properly flushed, prior to fitting the traps to avoid strainer choke-up.
