Sealed Steam Traps

The SIB30, SIB30H and SIB45 are all stainless steel sealed inverted bucket steam traps. They are supplied with a specified pressure change assembly depending on the required operating pressure differential. The traps are available with a range of seat sizes to suit pressure differentials between 0.5 to 30 bar (7.25 to 435 psi) for the SIB30/ SIB30H and 0.5 to 45 bar (7.25 to 652.5 psi) for the SIB45. Traps for 45 bar are also provided with an inbuilt check valve as standard.

The T3 is a forged stainless steel automatic steam trap. It is designed for instrument tracing or draining low capacity lines. The T3 operates with no loss of steam, and quickly drains air, non-condensable gases and large quantities of cold water on start-up.

The TSS21 all stainless steel steam tracer trap is a completely sealed unit and therefore has no gasketed joints. It is operated thermostatically using a balanced pressure capsule and is specifically suitable for non critical tracing applications. It is however a dual purpose trap in that it can be fitted in the reverse mode where it will operate as a fixed temperature discharge steam trap. The trap fitted in the reverse mode will limit the downstream temperature to approximately 90°C (194°F) when discharging to atmosphere. In the unlikely event of the trap operating into a pressurized return main the capsule will be affected by the downstream temperature and its operation under such conditions may be erratic and unpredictable.

 

Treating small traps as replaceable items makes more sense because:
  • The cost and complication of stocking spare parts is avoided.
  • The planning of maintenance schedules is minimized.
  • Replacement sealed traps utilize a non-remakeable joint, eliminating the risk of leaks to atmosphere.
