Steam traps play a role in entire steam systems by removing condensate, air, and other non-condensable gases, as well as preventing steam leakage. The proper operation of a steam trap ensures optimal energy savings and improved economic efficiency. Therefore, the inspection and maintenance of steam traps are also very important. Recommendation: When installing steam traps, the following points should be taken into consideration: 1. Before installing the steam trap, the connecting pipes must be thoroughly flushed to remove any foreign objects and dirt from them. 2. The direction of the condensate flow must be consistent with the arrow indicator on the steam trap. 3. The installation location of the steam trap should be as low as possible below the equipment’s condensate discharge point. If the installation location of the check valve is higher than the discharge point, a lift fitting must be used at the lowest point. If water hammer and vapor blockage occur frequently in submerged coils, a trap should be installed at the bottom of the coil, along with supply pipes of small diameter. 4. Install steam traps on the steam pipes; a condensate collection tank should be provided on the main pipe, with its size being close to the radius of the main pipe, and small pipes should then be used to lead the condensate to the steam traps. 5. A filter should be installed in front of the steam trap to ensure that it is not clogged by debris in the pipes, and the filter should be cleaned regularly. (If Lindwirt thermal dynamic steam traps and inverted drum steam traps have been purchased, there is no need to install additional filters, as they already come equipped with filters of their own, which saves on the cost of external filters.) 6. Shut-off valves should be installed before and after the steam traps to facilitate their installation, removal, and replacement. 7. A check valve should be installed before the condensed water flowing after the steam trap enters the main recovery pipe, to prevent backflow of the condensed water. 8. If condensate is to be recovered after the steam trap, the outlet pipe of the steam trap should be connected to the main pipe above the recovery main pipe, in order to reduce back pressure and prevent backflow. 9. Steam traps should not be installed in series. 10. Each piece of equipment should be equipped with its own drain valve. 11. In the event of steam leakage from the check valve, it is necessary to drain the waste water and clean the filter screen promptly, as well as repair the fault as soon as possible. 12. When using a steam trap, the maximum operating pressure difference specified on the nameplate or printed on the valve must not be exceeded; exceeding this value will result in malfunction of the valve.
