1. Before installing the steam trap, ensure that the pipeline is purged with pressurized steam to remove any debris or foreign particles. This helps prevent blockages and ensures smooth operation.
2. A filter should be installed before the trap to protect it from dirt and debris. Regular cleaning of the filter is essential to maintain efficiency and avoid clogging.
3. Install valves both before and after the trap for easier maintenance and repair. This allows you to isolate the trap without disrupting the entire system.
4. The direction of condensate flow must match the arrow marked on the trap. Installing it in the wrong direction can lead to improper function and reduced performance.
5. The trap should be installed at the lowest point of the equipment’s outlet to allow for efficient drainage of condensate. Timely discharge prevents steam buildup and reduces resistance in the pipeline.
6. If there is no suitable low position for the trap at the end of the equipment, install a backwater bend (condensation water lifting joint) at the lowest point of the drain. This helps raise the condensate level before connecting the trap, reducing steam resistance.
7. The outlet pipe of the trap should not be submerged in water. If it is, consider drilling a hole in the bend to break the vacuum and prevent backflow of water or sediment.
8. Mechanical traps should be installed horizontally to ensure proper operation and longevity.
9. Steam traps should not be installed in series. Each device should have its own dedicated trap to avoid inefficiencies and potential failures.
10. Every piece of equipment should be equipped with a steam trap to ensure effective condensate removal and system efficiency.
11. For thermostatic traps, it is recommended to install at least one meter of non-insulated subcooling pipe before the trap. For other types of traps, they should be placed as close as possible to the equipment to optimize performance.
12. When using steam traps in drum-type drying equipment with siphon systems, specify the use of a trap with an anti-steam resistance device to prevent steam lock and ensure smooth operation.
13. If condensate is being recovered, the recovery line should connect above the trap’s outlet manifold. This helps reduce back pressure and prevents condensate from flowing back into the system.
14. Condensate from different pressure levels should be recovered separately to avoid mixing and potential inefficiencies.
15. After the trap, the condensate recovery manifold should not rise uphill, as this increases back pressure on the trap and can cause operational issues.
16. A check valve should be installed before the condensate enters the recovery manifold to prevent backflow and ensure one-way flow of condensate.
17. Install a trap on the steam line. A condensate collecting well should be located near the main pipe bend to collect condensate before it reaches the trap.
18. If mechanical traps are not used for extended periods, the drain plug should be removed to drain all internal water. This prevents freezing and damage during cold weather.
19. If the steam trap is found to be leaking steam, it should be inspected immediately. Clean the filter and check the system based on usage conditions. Repairs should be made promptly. At a minimum, perform annual inspections to remove impurities and ensure continued reliable operation.
