How to reasonably select and use sealing gasket media , temperature, pressure and working conditions should be important factors. For example, when the working pressure is not high, plastic flange docking (PN) is used. For another example, in a working environment with chemical media, different sealing media must be reasonably matched to achieve good results, otherwise unpredictable chemical changes are prone to occur. Therefore, any paradox in the selection of seals will lead to unimaginable consequences. Generally, the gasket structures have the following types for reference: 1. For flange...

Gasket selection When any type of gasket is used, in order to ensure long-term effective sealing, the following eight important characteristics must be paid attention to when selecting and using the gasket: 1. Gas seal of gasket For the medium of the sealing system, the gasket can be used for a certain time within the appropriate temperature and pressure range without leakage. 2. Compressibility of gasket After the connection bolts are tightened, the contact surface of the gasket and flange should be well matched to ensure the sealing 3. Creep resistance of gasket Under the influence of...

Plate heat exchanger gasket is a device used to increase the heat transfer efficiency of the heat exchanger. It can increase the heat transfer area and heat conduction efficiency of the heat exchanger. Here's how it works: 1. Increase the heat transfer area: Plate heat exchanger gaskets are usually made of metal materials and have a certain thickness. After installing the gasket, multiple narrow channels can be formed inside the heat exchanger, thereby increasing the heat transfer area. These channels allow the fluid to form a complex flow path inside the heat exchanger, increasing the...
