How to deal with a leaking steam valve?
Thread Content
The unit is equipped with an air preheater, and the medium used for preheating is medium-pressure steam in a quantity of over 30 kilograms. The control valve before the steam enters the preheater keeps leaking; although clamps have been used on the flanges, this has not resolved the problem. Does anyone with experience have any suggestions?
It can be completely resolved by using proper pressure-based leak sealing techniques (have a professional company handle it). Simply putting a clamp on it won’t solve the problem with such high pressure.
Find a reputable company specialized in plugging leaks under pressure; it usually takes about three attempts to achieve a good result~~~~
It basically doesn’t work. Hire a professional company to perform leak sealing under pressure. On-site, measure the outer diameter of the flange as well as the misalignment deviation, and design and manufacture fixtures based on the medium, temperature, and pressure parameters. After the clamping device is installed, inject the sealant (special).
Is there a simple way? Don’t hire a professional leak repair company
I’ve seen that wrapping valves on medium-pressure pipelines also gives good results; hiring a professional leak-sealing company is too expensive. Are there any other methods?
It is recommended to leave this task to professional technicians specialized in plugging leaks under pressure; such situations are very dangerous, and attempting to handle them on one’s own will only bring harm with no benefits. What will you do if something goes wrong?
Thanks for the reminder; I wouldn’t know how to do it – the pressure is simply too much, it’s terrifying
Agree with the view from floor 8; leave professional tasks to professionals – it’s very dangerous for operators to work under pressure.
