Metal wound gasket
It is a high-quality alloy or stainless steel belt material, with graphite, asbestos, PTFE as filler material, for "V" or "W". "V" or "W" type spiral winding. Used in petroleum, chemical, machinery, metallurgy, electric power, shipbuilding and pipeline, valves, pumps, pressure vessels, condensers, towers, manholes, handholes and other flange connections, for static sealing. Due to high mechanical strength, easy to use, good compression resilience, more adapted to the application in the dramatic temperature fluctuations.

Polytetrafluoroethylene gaskets are made of PTFE suspension resin at room temperature by push and molding. It is made of PTFE suspension resin at room temperature by pushing and molding method and then sintered.
Suitable for temperatures of 180 ℃ -250 ℃ in a variety of corrosive media for gasket sealing and lubrication seal, and there are in a variety of frequencies used in the electrical insulation material.
Tetrafluoro gasket polytetrafluoro gasket pure PTFE gasket PTFE gasket PTFE gasket manufacturers Hebei PTFE gasket PTFE gasket polyethylene PTFE gasket Teflon gasket Teflon gasket # full name of the polytetrafluoroethylene gaskets abroad, also known as PTFE gaskets or Teflon (Teflon) gaskets made of polytetrafluoroethylene rods, tubes, plates by mechanical turning or cutting of flat gaskets, V-shaped gaskets, piston rings, ball valve gasket With corrosion resistance, anti-aging and non-conductive and other good characteristics of the selected materials: PTFE powder, PTFE plate Temperature: -150-250 ° C Using pressure: 6.4Mpa
The main purpose of the high cleanliness medium
Available specifications DN10-600mm. PTFE pH 0-14 (molten alkali metals and high temperatures, high pressures, except for fluorine). It can have good mechanical strength between -100℃～100℃. Pressure 10Mpa.
Note: At temperatures below -185℃. PTFE gasket will become brittle. Pure PTFE gasket is a clean sealing product that will not contaminate any substance it comes in contact with, and can be widely used in food, medicine and other industries.
Tetrafluoro gasket polytetrafluoroethylene (abbreviated as PTFE), also become Teflon (Teflon in English) has a series of excellent use of performance:
1) high temperature resistance - long-term use of the temperature of 200 to 260 degrees,
2) low temperature resistance - at -100 degrees is still soft;
3) corrosion-resistant - resistant to aqua regia and all organic solvents;
4) weather-resistant - the best aging life among plastics;
5) high lubrication - with the smallest friction coefficient (0.04) among plastics;
6) not Adhesion - has the smallest surface tension among solid materials without adhering to any substance;
7) Non-toxic - physiologically inert;
8) Excellent electrical properties, is the ideal class C insulating material.
Polytetrafluoroethylene is widely used in machinery, automobiles, electronics, chemical industry, valves and other parts because of its highest temperature resistance in plastic (260 ℃), the highest resistance to electricity (45KV/mm), resistance to strong acids and alkalis, the most anti-adhesive, the most slippery, wear-resistant engineering plastic materials. Teflon hose is widely used in chemical, instrument, electric heating, mechanical industry; which insulating sleeve due to high temperature, voltage (300V) and widely used in aerospace, automotive, medical, electronic transformers, communications and other scientific and technological industries
