Introduction of high temperature and high pressure sealing gasket

In fact, there are many materials for high temperature and high pressure gaskets, but you must choose a high temperature and high pressure gasket that suits you according to your working conditions. Speaking of this, you may want to know what high temperature and high pressure gasket? Below, will introduce several high temperature and high pressure gasket products.

In fact, there are many materials for high temperature and high pressure gaskets, but you must choose the high temperature that suits you according to your working conditions.High pressure sealPad. Speaking of this, you may want to know what high temperature and high pressure gasket? Below, will introduce several high temperature and high pressure gasket products.

1. High temperature and high pressure spiral wound gasket, spiral wound gasket is a kind of sealing gasket made of metal and flexible material wound by equipment. Graphite can be used for common high temperature requirements. Since graphite is a high-temperature resistant material, and metal materials can ensure the high-pressure resistance of the sealing gasket, the graphite added with metal can meet the requirements of high-temperature and high-pressure resistance, and due to the strengthening of metal, its resilience is better than other gaskets. At the same time, if there is a higher pressure requirement, a metal ring can be added inside, which can well protect the sealing surface of the gasket from being squeezed under the impact of greater pressure, so as to achieve a good sealing effect. Adding inner and outer rings can also facilitate us to middle the gasket during installation and install it properly. When purchasing, pay attention to the different types of high temperature and high pressure metal winding pads for different flange surfaces, such as basic type, inner ring type, outer ring type, inner and outer ring type, which are suitable for different concave and convex flanges, RF boss flanges, flat flanges, etc. The wrong gasket type cannot be installed and used, you can also consult or contact us to provide you with detailed answers.

2. High temperature and high pressure metal graphite composite gasket, also known as high strength graphite gasket or RSB graphite gasket, is a gasket made of graphite and metal composite. However, this process is different from the process of winding a gasket. Graphite composite gasket is a high temperature and high pressure gasket gasket with a layer of metal in the middle, punched in the metal, and then glued on both sides. Because there is a layer of metal plate in the middle, it can meet the sealing requirements of high temperature and high pressure. Can also be used metal edging, make it become edging type, in order to increase the overall strength of the gasket, to meet the requirements of better pressure resistance. At the same time, it can be made into square hole, round hole, diamond hole and other special-shaped gaskets, which are mostly used for high temperature and high pressure resistant parts such as flanges and exhaust pipes.
