Introduction to the use of PTFE sealing tape

PTFE sealing tape. A kind of sealing packing made of polytetrafluoroethylene resin processed by special process, because it is made of fine long fibers and expanded network of nodules, the product is soft, tough and easy to deform, so it has more advantages than general sealing materials. For superior sealing performance, it is suitable for temperature resistance -50℃～+200℃, and the working pressure is ≤16kg.F/cm2. Vacuum degree (200mmHg (pressure) under the appropriate sealing structure, the product specifications of the sealing material meet the technical requirements of Q/GHAD003-91.

Application: It is suitable for packing seals of various valves, flange seals of various reactor tower sight glass, also suitable for static seals of flanges with large diameters and dynamic seals of slow speed such as stirring shaft seals, gear pump seals, linear speed ≤ 1 m/s.

According to the needs of users, for special specifications, the two parties negotiate to open molds for custom processing and production, and the price is negotiable according to the quantity.

It is a new type of sealing product, which can replace gaskets, gaskets and other sealing products. It is a very novel and unique sealing material made by advanced processing technology. It is a continuous strip of white pure PTFE product with good flexibility, compression resilience, creep resistance, high and low temperature resistance, excellent corrosion resistance, no aging, self-lubrication . Sealing performance, easy installation and use, is an ideal sealing material for chemical, pharmaceutical, petrochemical, food and beverage, electronics, electric power, metallurgy, shipbuilding and other industries. Peng body PTFE sealing tape is a new type of sealing product. It is a breakthrough of new technology at home and abroad in the field of sealing. It has changed the traditional use of static sealing. It is a new concept of high-quality and practical sealing tape. Significant functional sealing products.

Because of its softness, large compression ratio, and easy forming in three-dimensional space, PTFE tape can be embedded into tiny cracks and damaged parts to repair cracks and plug leaks, especially in the connection of acid resistance, alkali resistance, corrosion resistance, non-metallic equipment, and large-diameter containers. Prominent, can effectively protect the device connection of brittle materials. For non-metallic devices such as glass, ceramics, graphite, plastics, etc., it has an extraordinary effect. It can compensate and balance the errors caused by defects, machining, PTFE elastic belt, rigid deformation, installation dislocation, etc., balance the uneven preload, and can effectively solve the leakage problem of various facilities under complex conditions. Secondly, the gasket of the expanded polypropylene interface sealing tape is white, pure, and pollution-free. Hubei PTFE elastic belt meets FDA/USDA use standards. The only hygienic grade product used in the production device can protect the high purity and anti-pollution of the medium. The anti-corrosion performance of the expanded polypropylene interface gasket is especially suitable for application in chemical, petrochemical, petroleum and other production equipment with a large amount of corrosive medium. Technical parameters: Working temperature -268～316℃ Working pressure 20 MPa ·Applicable medium All chemical substances except elemental fluorine and molten alkali metal. Density 0.6～0.8 g/cm3 Use of PTFE tape · Various enamel linings, glass linings, plastic linings, rubber linings, graphite linings, and flange surfaces of stainless steel and titanium steel towers, heat exchangers, and reactors.
