Installation of gaskets for heat exchanger maintenance
The heat exchangers used in chemical companies are mostly pressure vessels. Therefore, it is necessary to carefully check whether the gasket has radial scratch defects, whether there is a problem with its own material, whether there is an installation quality problem, otherwise serious quality accidents are likely to occur.
The most difficult installation of all types of gaskets is the installation of the backrest pad between the tube bundle and the shell. The gasket should be placed on the inner side of the tube bundle flange before the tube bundle is placed on the core pulling machine to avoid damage to the gasket during the tube bundle reinstallation process. piece. In addition, it should be noted that the sealing surface of the flange should be cleaned in time, and the color striped cloth should be used for shielding, the PTFE gasket should be used before installation, and the flange should be coated with butter to fix the gasket and other prior control measures.
