Regarding the graphite condenser matter
Thread Content
I seek advice from all the experts! The graphite condenser passed the pressure test for leak detection before installation ； Is it still necessary to perform pressure testing after the installation is complete and the pipes are connected? If not fighting, then why? Hit, why? Thank you! Please advise!
It is needed. During installation, there may be collisions, loose bolts, or damaged graphite blocks; a pressure test is required to determine whether the condenser is leaking.
Suppression is required; after the equipment is installed, pressure testing should be carried out together with the pipes. Since most graphite heat exchangers are in block form (they are installed vertically during assembly, but are usually loaded horizontally during transportation), bumps and collisions are inevitable during transportation and lifting. So it is recommended to check the pressure before driving.
After installation, a system pressure test must be conducted before driving; the test pressure is set at the operating pressure of the system, and it is primarily used to check the sealing quality of the connections between equipment, pipelines, and fittings.
It is recommended to do so, as there may be issues with thermal expansion and contraction after the fluid flows in...
Suppression is necessary. After installation, all the screws need to be tightened. It is assembled vertically; transportation in a horizontal position may cause loosening, but it won’t lead to leakage, so the screws need to be tightened.
