Ordinary PTFE has better mechanical properties, electrical properties, chemical resistance, creep resistance, processability, etc., and its advantages are more obvious in engineering fields that require higher safety and reliability.

Wrap the graphite packing on a tube with the same diameter as the shaft, wind it tightly but not stretch it, and cut it after alignment. Note: Do not use the method of surrounding the stuffing box to measure the length. Cut off the first sealing ring, try

This kind of heat preservation and heat insulation board has unparalleled excellent performance of other similar boards: it has good heat preservation and heat insulation performance with its extremely low thermal conductivity; it has excellent waterproof

PTFE flange gasket is a kind of non-metal gasket, generally composed of two parts, covering layer and insert. The coating layer mainly plays a role of corrosion resistance and is usually made of polytetrafluoroethylene. The insert (filler) is a non-metall

Core Tip: The effective sealing of pumps and valves depends on the overall condition of each component. Pay special attention to the fact that before packing installation, make sure that the equipment that needs to be replaced has been effectively isolate

①Surface condition of the sealing surface: The shape and surface roughness of the sealing surface have a certain influence on the sealing performance, and the smooth surface is good for sealing. Soft gaskets are not sensitive to surface conditions due to

With the continuous emergence of production technology, the weaving forms of packing packing have gradually diversified. According to different use conditions and environments, different weaving forms have a direct impact on the performance and service li
