Cleaning methods for shell and tube heat exchangers
There are many such posts on the forum; you can find plenty by searching. Go and look for them yourself. Here’s one example for you: http://bbs.hcbbs.com/viewthread.php?tid=338019
Chemical cleaning is recommended, with intermittent pauses, to ensure thorough removal. You can send me a message to discuss in detail; I specialize in cleaning
Let’s see what’s blocking it; we usually open the cover and use a high-pressure water gun to clean it.
Thank you :handshake :handshake :handshake
What was said about the upper floors is correct – open the cover, and if the pipe is blocked, just use a high-pressure water gun to clean it; our factory used this method frequently in the past, with pressures reaching 2000 bar. That’s an extremely high pressure! ! ! ! ! ! ! !
Different cleaning methods are used for shell-and-tube heat exchangers with various purposes. The specific methods include: 1. Using a high-pressure water gun for cleaning； ⒉Blow with steam ； ⒊Chemical cleaning and mechanical cleaning.
After opening the cover, it is necessary to check whether it is scale or carbides. If it is scale of the calcium carbonate type, chemical cleaning methods can be used; if it are carbides, high-pressure cleaning equipment is required! Chemical methods generally use hydrochloric acid, and corrosion inhibitors must be added to prevent it from damaging the equipment! Safety must be observed when using high-pressure washers, as the pressure is high – generally 500 kilograms in China, while imported equipment abroad can reach 1000 kilograms! Never point the high-pressure nozzle at a person while it is under pressure!
