How to choose a marine gasket

2022-01-03

 There are many types of marine gaskets, which are generally divided into metal, non-metal and composite gaskets according to materials and structures.
 
Asbestos is recognized as a strong carcinogen. Therefore, when selecting, it is forbidden to use asbestos and its products on ships. The correct selection of gaskets is the key to ensuring that equipment and pipelines do not leak. It should be based on the physical properties of the medium, pressure, temperature and equipment size. , operating conditions, length of continuous operation cycle, etc., reasonable selection of gaskets. When choosing a gasket, you should fully consider:
 
Good elasticity and recovery, can adapt to pressure changes and temperature fluctuations
 
Appropriate flexibility, can fit well with the contact surface
 
Does not pollute the medium
 
Sufficient toughness without damage due to pressure and tightening forces
 
Does not harden at low temperature and has little shrinkage
 
Good processing performance, easy installation and pressing
 
Non-stick sealing surface, easy to disassemble
 
Inexpensive and long service life
 
In the use of gaskets, pressure and temperature are mutually restrictive. As the temperature rises, after the equipment has been in operation for a period of time, the gasket material will soften, creep, and stress relax, and the mechanical strength will also decrease. The pressure of the seal is reduced, and it is very necessary to replace the gasket regularly. Changsha Haochang Machinery Equipment Co., Ltd. provides high-quality marine metal gaskets that are well received in overseas markets.
