Steam trap maintenance and checks

Regular checking and proper maintenance of steam traps is essential for the correct operation and high performance of our system, so at this point it is advisable to carry out all the necessary checks and actions to ensure that our steam traps work as expected. A lack or poor detection of problems in them can trigger operating problems that result in loss of performance and, if not corrected in time, end up deteriorating the whole system. In the following, we will explain which checks and maintenance tasks are the most appropriate for steam traps:

Checking steam traps

Indiscriminate trap maintenance costs money. The trap may be:

• Working properly. 
• Leaking steam.
• Being obstructed.

The detection of defective traps has always been a problem, a diagnosis that has been difficult to make.stico erróneo can cause defective traps to continue to give problems and cause unnecessary replacement of properly working traps. Consequently, the diagnosis ofThe exact calculation is important in any maintenance programme.

Sight glasses may offer a solution, especially the sight glass/check valve which gives a visual indication of flow as well as acting as a check valve, however, sight glasses will require the glass to be replaced. The inadequacies of listening devices have led to temperature monitoring, but it is quite feasible (and normal) for condensate and steam to co-exist at the same temperature in the same system, making diagnosis difficult.The exact calculation by temperature.

In the hands of a trained and experienced operator, the ultrasonic tester can be used with good results, but in the hands of a novice, it is easy to misdiagnose that the trap has failed when, in fact, it has not.

Inconsistencies in theéall of the above have led to and determined the development of traps incorporating an accurate and reliable testing device.

It consists of a sensor, mounted inside the trap, which is capable of detecting the physical state of the trap.sico of the medium at that point by conductivity. It is not affected by the alteration of the revaporisation. The result is accurate and not subject to interpretation. Monitoring can be performed locally or remotely and manually or automatically, and a fault can be discovered immediately, thus minimising costs and maximising investment.

A thermocouple inside the chamber detects and can help predict blockages, so they are particularly useful, especially in hydrocarbon industries and processes that depend on process continuity.

For steam users who prefer to use steam traps without integral sensors, or for larger applications requiring larger traps, sensors can be supplied in separate chambers.

Benefits of preventive maintenance of steam traps

The benefits of preventative steam trap maintenance keep steam traps working properly, create a safer working environment and save energy in the facility.

A malfunctioning steam trap can increase the force of water hammer and cause a filter or valve to explode. This is a potential safety hazard as well as a risk of additional damage to the equipment.

Steam traps that are clogged and open allow steam to escape continuously, wasting energy as long as this condition is not recognised. According to Spirax SarcoA steam trap that has not been maintained can cost thousands of dollars in lost energy per year.

Routine maintenance of steam traps

Routine maintenance depends on the type of trap and its application. The balanced pressure trap, for example, has an element that is designIt is designed for easy replacement.

Replacement of interns

Estclearly it makes sense in a good steam trap maintenance plan to renew the internal parts of a steam trap. The body generally has a life as long as the plant in which it is installed and only the internal parts are dependent on the condition of the system.

Replacement of steam traps

In some places the high cost of labour precludes the repair of all but the largest traps. In these cases it is essential that the traps can be easily replaced.
