High temperature gasket Basically belongs to the sealing parts of flange parts, which can improve the working efficiency and quality of the whole equipment. In the equipment, most of the chemical and petroleum equipment, ships, papermaking and pharmaceutical preparation equipment contain flange parts. Its main function is to connect two different pipes together, so as to maintain and connect all parts of the equipment. In order to ensure the sealing of the connection, high temperature resistant gasket has become one of the necessary materials. So when you choose the flange gasket, what problems need to pay attention to?

 What should be considered in the selection of high temperature gasket for flange part between pipes

1: Understand the equipment temperature and find the right core products

The flange interface mode and the environment in different equipment are also different. For example, some pipelines have ultra-high temperature at the flange interface, so the resistance of high-temperature gasket needs to be improved. Many civil equipment may have a high temperature of 100 ℃ or 200 ℃ in the flange, so we only need to select some semi metal high temperature resistant gasket or similar stainless steel high temperature resistant gasket. For the performance requirements of this relatively low, there are not too many requirements for raw materials, only need to protect its sealing and easy to operate.

2: Understand the pressure of the equipment and determine the required products

When selecting high temperature gasket for flange, the pressure will be taken as a very important core base number as a reference value. Especially if the pipeline transportation is steam and so on, the pipeline pressure is high, the direction that needs to be considered needs to be taken as the focus. Take the standard flange of 150Lb as an example, its pressure level is not high, so some soft flat gasket can be selected. If it is more than 300lb, some metal high temperature resistant gasket or spiral wound gasket can be selected according to the flange condition. When the two pipes are directly connected, the wound gasket can play a good role in preloading, so as to improve the connection of pipes.
