Thermostatic steam trap repair in five easy steps
When your thermostatic steam trap needs to be repaired, the “Barnes &Jones/Edison Element” — called acage unit— is a cost-efficient and easy-to-implement solution. The self-contained, one-piece cage unit is designed torepair thermostatic steam traps from a long list of manufacturers without takingthe trap body offline. Available from Keystone Steam Supplies, these cage unitsare 100 per cent factory calibrated and tested under live steam and condensateto ensure uniform operation in the field. Another plus: there are no pipingconnections that need to be broken or multiple internal components to beremoved. The body of the trap acts as a housing for the cage unit, whichperforms the steam trap functions.
The cage unit makes it easy to repair a steam trap — so easy that it can be donein five simple steps.
Step 1:Determine the make and model of the steam trap that needs to berepaired.
Step 2:Select the proper Edison kit and colour-coded spring (for repair using theEdison cage unit), or select the correct Barnes & Jones cage unit from the table(for repair using Barnes & Jones cage units).
Step 3:Take out the existing trap cover and all of the internal components.
Step 4:Add in the new cage unit.
步骤5:Finish by reinstalling the existing trap cover (or new cover if required).
Replacing a cage unit offers two distinct advantages over replacing an entiresteam trap. First, it is much more cost-efficient to repair an existing trap rather比不替换它w one. Second, it’s far easier to replace the thermostaticelement instead of the entire trap body. In fact, in most cases there is nothingwrong with the steam trap body; it’s only the thermostatic element or seat that isfaulty. Why go through the extra hassle of removing the trap from the line when anew cage unit is all it needs to work properly again?
Even if the existing trap seat is damaged by scouring, pitting or wire-wicking, theexternal gasket on the cage unit will expand upon exposure to moisture. Thismeans that a faulty trap can still be repaired with a new cage unit.
