What special problems should be paid attention to in the installation of PTFE gaskets?

Ptfe gasket manufacturers have many applications as sealing materials. Because of its high corrosion resistance, stable physical properties, high and low temperature resistance, it has a good sealing performance, and has a wide range of applications in petroleum, chemical, pharmaceutical, electric power, steel industries. Soft polytetrafluoroethylene refined. Durable, reliable sealing performance; Polytetrafluoroethylene itself has the best corrosion resistance and non-aging, and has good creep resistance and cold flow resistance after special processing; Can be used safely over a wide temperature range for a long time; Soft and easy to cut, can be cut mechanically or by hand, easy to install.

Ptfe gasket manufacturer features:

Ptfe gasket is a good static sealing material, it is composed of asbestos plate, rubber and other elastic materials with PTFE coated laminated laminated elastomeric shrapnel. Polytetrafluoroethylene has outstanding chemical corrosion resistance and the characteristics of a wide temperature range, in addition to high temperature melting alkali metals and elemental fluorine, it is not subject to any chemical attack. It has a very low coefficient of friction, excellent oxygen resistance, and is a non-stick material.

Ptfe gasket manufacturers need to pay attention to the installation of products:

1, the sealing line or sealing surface of the PTFE gasket seal surface can not be damaged. Flat PTFE gasket seals can rely on the upper and lower end faces; The sealing performance of hydraulic PTFE gasket seals is mainly through the lip line related to the shaft or hole. These parts are composed of soft and resilient corrosion resistance, temperature resistance, aging resistance of graphite, fiber, rubber and plastic and other special materials that are vulnerable to damage, so special care is needed in the installation, handling and storage process. Once damaged, it will bring a very big hidden danger to the sealing part.

2, the installation process should not be too large forced loading, which will cause the original prefabricated structure of our PTFE gasket seals to be destroyed. Therefore, we should be very careful when installing PTFE gasket seals, and the embedding step must be carried out gradually.

3, the installation of PTFE gasket seals must follow symmetry and balance. Place the PTFE gasket seal just above the lip surface during installation. After the system is opened for use, it is necessary to continue to observe and do a good job of the follow-up work of the PTFE gasket seals, so as to prevent the outburst caused by micro-leakage due to changes in working conditions (such as pressurization) during the working process of the system.
