Product Content Description:

1. Wide range of applicable working condition
2. Strong stress compensation, stable sealing performance
3. Easy installation
RS-5001 Spiral wound gasket is formed of V-shaped metallic strip and connected its end & beginning by DOT welded. Depend on its excellect compression resilience. It is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal, exchanger, condensing tower, plain hole and man hole of flange, etc.
Please offer the detailed drawing, while the gasket is used in thermal exchange if it with some ribs.
PTFE is principally used as a gasket material because of it's capability to remain unaffected by the majority of chemicals used in industry. It is also classified, in most cases, as a food grade material, making it acceptable to both medical and food production industries. There are three basic types of PTFE gasket materials. Virgin PTFE, filled PTFE and expanded PTFE.
Virgin PTFE is by far the least expensive of the three varieties, and is used in most general applications. Filled PTFE is a gasket material with a virgin PTFE base to which a substance is added during manufacture to improve the sealing characteristics of PTFE. This "filler" usually is glass or graphite particles although ceramics has sometimes been used. the resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.
Expanded PTFE is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the PTFE is constructed, do not arrange themselves into set patterns. This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE.
