PTFE double-layer seamed covered ring.*
Double-layer PTFE covered ring
PTFE double-layer seamed covered ring has the smallest inner diameter and the smallest wire diameter. For other specifications, please contact us. Call us for consultation. The polytetrafluoroethylene sheet is coated on a silicone or fluorine rubber core with a special process, and the inner and outer layers of circumferential seams are staggered.
Features: Pressure-resistant, high softness and easier to install than similar products.
Main advantages, strong resistance and versatility, suitable for almost all chemical media, only corroded by a few chemicals at normal operating temperature. Here are only some chemicals that are not compatible with it. Incompatible with metallic bases, fluorine and some halides. Some high-concentration chemicals will react with it upon contact. At high temperatures, it will be affected by % and, metal hydrides such as ( ), aluminum chloride, ammonia ( ) and some ( ) and imino (r =) organic compounds. of erosion. When the temperature reaches ℃, it will also be corroded by the chronic oxidation reaction of % acid. Products must undergo special testing if used under these extreme conditions. The chemicals are generally chemically inert towards chemicals other than those mentioned.
, wide temperature range - ℃ ~ ℃ can be used at high temperature for a short time
, good compression resistance. The existence of the outer coating makes the product have good resistance to hardening and brittleness while silicone The rubber or fluororubber inner core allows it to maintain good elasticity at high temperatures of ℃. The test results show that the sealing ring formed by combining the physical properties of silicone rubber or fluorine rubber with the chemical properties has good compression resistance while maintaining rubber properties.
Anti-friction Due to the extremely low friction coefficient (.) of polytetrafluoroethylene, it becomes the variety with the smallest friction in the ring family, which is of great help and support for reducing equipment wear and improving equipment power and efficiency.
It is recommended to use a retaining ring type pressure ring to withstand high pressure and can withstand up to the above pressure.
Excellent sealing durability and long service life. Compared with any other rubber or pure ring, it has unparalleled sealing performance and long service life, especially when used in harsh media.
, moderate hardness, the average hardness of sealing rings made of different materials is solid silicone rubber - solid fluorine rubber - hollow silicone rubber -, clean and environmentally friendly, non-toxic, cleanliness and temperature resistance at normal use temperatures make it a food It is one of the necessary production equipment accessories in scientific research and production fields with extremely high hygiene requirements such as medicine, fine chemicals, and bioindustry.
Specifications The minimum inner diameter is the smallest wire diameter. The maximum size is unlimited
Applications Pumps and valves, reaction vessels, mechanical seals, filters, pressure vessels, heat exchangers, boilers, pipeline flanges, gas compressors
