Product Description:

1.Description of Gasket :
Ginseal Spiral-wound gaskets comprise a mix of metallic and filler ma- terial. Generally, the gasket has a metal (normally carbon rich or stainless steel) wound outwards in a circular spiral (other shapes are possible) with the filler material (generally a flex- ible graphite) wound in the same manner but starting from the opposing side. This gasket is formed with stainless steel 304/316 and graphite,non asbestos,ptfe or other seal material. It is the best gasket for muffler pipe or flang gasket.It could be standard style,it just formed stainless steel and graphite or non asbestos etc.It could be add inner ring or outter ring.The material ring  could be carbon steel or stainless steel.

2.Features of Gasket :
• Wide range of applicable working condition,high temperature and high pressure resistance,applicable to super low temperature and vacuum condition.Chemical resistant gasket is available under various medium,through change of composition of gasket.
• Strong stress compensation,stable and reliable sealing performance even under frequent pressure fluctuation condition.
• Perfect sealing performance.
• Normal requirement of flange surface finishing which contact with gasket.
• Easy installation and low pre-tightening stress of gasket.
• Heat treatment industry for furnace parts, fans, tube hangers, and baskets and trays to hold small parts.
• Chemical process industry to contain hot concentrated acids, ammonia, and sulfur dioxide.

4.Specifications of the Gasket:
1.A good compression ratio and elasticity.
2.With plastic appropriate, after pressing can adapt to the sealing surface and sealing surface uneven fill the gap, to ensure good sealing performance with the temperature and pressure in the system of alternating case.
3.With excellent corrosion resistance, not to be damaged in some extreme medium, does not have the expansion and contraction.
4.Under the condition of high temperature softening, does not creep; under the condition of low temperature hardening, does not shrink.
5.Have sufficient strength, when external load conditions, not be crushed; at high temperature, not blown out.
5.FAQ

Q:What kinds of vulcanized rubber do you have?
According to the properties and uses of rubber: in addition to natural rubber, synthetic rubber can be divided into general synthetic rubber, semi general synthetic rubber, special synthetic rubber and special synthetic rubber.
Q:How is the temperature range of rubber determined?
Vulcanized rubber is related to vulcanizing reagents, fillers and so on! The low temperature limit generally refers to the glass transition temperature. Of course, the finished rubber also has the physical properties required by the customer for the low temperature dynamic work!
Q:What is rubber damping material?
Butyl rubber, butyl bromide and butyl chloride are the main ones!! Need to design, sell rubber products, can find me!
Q:Several aspects of rubber aging performance and how to identify them
The chemical activity of ozone and ozone is much higher than that of oxygen, and it is more destructive. It also breaks the molecular chain, but the effect of ozone on rubber varies with the deformation of rubber. As for the deformation of the rubber (mainly unsaturated rubber), and there should be crack force perpendicular to the direction of the so-called "ozone cracking"; effect on the deformation of the rubber, only surface oxide film without cracking.
Q:What are the forming methods of rubber products?
In these methods, injection molding has the significant advantages of simplifying process, reducing the number of operators; second, reduce the energy consumption of about 10%; the production efficiency is improved by 4 ~ 7 times; improve product uniformity, stability, size precision and the qualification rate; reduce the flash, saving material and convenient operation;, low labor intensity, high degree of mechanization and automation. Therefore, in recent years, more and more attention has been paid to injection molding technology, and it has been developed rapidly in rubber products production
Q:What are the uses of rubber oil?
The effect of rubber regeneration: thick pine tar smoke containing regeneration agent of other small molecules, which can penetrate into the intermediate node containing uniform molecular sulfur rubber, the swelling, reticular structure relaxation, increased permeability and oxygen distance between molecular chains, also can be used as acceptor free the base, inhibiting gelation effect, also helps to accelerate the diffusion of the activator rubber matrix regeneration process, and can improve the regeneration of plastic viscosity and plasticity, and less pollution, good processing performance.
Q:How to maintain and store the rubber material?
Low temperature, dry, away from the fire, not direct sunlightSulfur and accelerant are stored separately,The foaming agent separates from the oxideEach material has a different shelf lifeCan find the manufacturer to product brochures and material safety materials and other related information
Q:What gum does rubber and metal stick together?
JL-480 black rubber instant glue: medium viscosity, high strength, etc. used for inert surface, bonding, porous, acid, vibration and heat resistance, rubber, metal, plastic bonding. The utility model can be used for large gaps and more dispensing. High viscosity, impact resistance. The curing is slow, the curing has toughness, and the adhesive force is strong. After bonding, the adhesive surface can reach two and the adhesive surface dissolves as a whole. It is a shock resistant instant adhesive, which has better seismic and stripping strength than other series. Widely used, bonding rubber, plastic, and metal as adhesive for impact resistance. It is more flexible than conventional adhesive.
Q:What are the differences in the properties of neoprene models?
Good physical and mechanical properties, oil resistance, heat resistance, fire resistance, sunlight resistance, ozone resistance, acid and alkali resistance, chemical reagents. The disadvantage is cold resistance and poor storage stability. With high tensile strength, elongation and reversible crystallinity, good adhesion. Aging resistance, heat resistance. Excellent oil resistance and chemical resistance. Weatherability and ozone resistance are second only to that of ethylene propylene rubber and butyl rubber. The heat resistance and the nitrile rubber, the decomposition temperature of 230~260 DEG C, short-term resistance at 80~100 DEG 120~150 DEG C, can be used for a long time, with a certain flame retardancy. Oil resistance second only to nbr. Good resistance to inorganic acids and alkalis. Cold resistance is slightly worse, electrical insulation is poor. Rubber poor storage stability, will have a "sulfur" phenomenon, Mooney viscosity increased, hard rubber. Foreign brands are: AD 1, 30 (USA), A-90 (Japan), 320 (Germany), and MA40S (France).
Q:What do you pay attention to when using rubber?
Note the aging of rubber rubber rubber and its products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the physical and chemical properties and mechanical properties of rubber gradually deteriorated, and finally lose value, this kind of change is called aging of rubber. The surface is characterized by crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..
