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 results in alternating layers of filler and metal. The filler material in these gaskets acts as the sealing element, with the metal providing structural support.
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.
• Normal requirement of flange surface finishing which contact with gasket.

Ask 3:Should i pay for it If some product need molds?
Answer:I'm afraid you should pay for it,However,We would return it back when we get the first order.
- Q: What problems need to pay attention to when inflating the pipe?
- Rubber pipeline plugging bag should keep the inner pressure of the gasbag is uniform when inflated, inflated slowly rising inflation, observe the pressure gauge without change, such as pressure gauge shows rapid rise in inflation is too fast, the inflation rate should slow down, stop valve will tighten slightly, reduce the inlet velocity, or the speed is too fast, faster than pressure is likely to break into the rubber balloon. - Zhang
- Q: How long is the warranty period for EPDM?
- (1). Rubber molding, after pressing, the elastic body is within the cohesion can not be eliminated, the molding die, often have a very unstable contraction (rubber shrinkage due to rubber vary), required after a period of time, and can be stable. Therefore, when a rubber product design at the beginning, regardless of formula or mold, it is necessary to carefully calculate the coordination, if not, it is easy to produce product size instability, resulting in lower quality products.(2). A rubber elastic body of thermosetting plastic hot melt, belongs to the hot cold setting. Rubber due to different types of sulfide species, its molding and curing temperature range is also a considerable gap, and even can be affected by climate change, indoor temperature and humidity affected. Therefore, the production conditions of rubber products need to be adjusted at any time. If not, the quality of the products may be different.(3) rubber products are made of rubber raw materials and used as raw materials made from the rubber compound of the mixer, and the formula is designed according to the characteristics of the required rubber products, and the required hardness of the products is determined. The product is made and molded by rubber flat vulcanizing machine. Finally, the product is processed by flying edge, and the surface of the product is treated smoothly without burrs.(4). Aging test of rubber products aging test belongs to the category of rubber aging refers to rubber and products in the processing, storage and use of the process, due to the comprehensive effect of internal and external factors caused by the performance of the structure change, then the loss of use value phenomenon. They are crazing, sticking, hardening, softening, powdering, discoloration, mildew, etc..
- Q: Rubber and metal have to be sealed before they are too strong
- The percentage difference between the first compression compression = original section diameter minus the trench size divided by the original O ring diameter O-ring compression is mainly depends on the material hardness and O-ring, O-ring if the hardness is 70 degrees, then the O-ring compression is equal to 20%. Of course, the lower the hardness of the O-ring, O-ring compression is greater, mainly used for low pressure places. Then the O-ring hardness increases the amount of compression of the O-ring is smaller, mainly used for high pressure, pressure resistance, resistance of small environment. And so on, the amount of compression can be any hardness O-ring you need.
- Q: How are rubber wires processed?
- In the production of rubber products, vulcanization is the last process.Vulcanization is a crosslinking process in which rubber molecules change from linear structure to network structure under certain conditions. Curing methods are cold vulcanization, room temperature vulcanization and heat vulcanizing three kinds. Most rubber products are vulcanized by heat. Hot vulcanizing equipment, vulcanizing pot, flat vulcanizing machine, etc.. Rubber wires and cables are vulcanized by continuous hot air.
- Q: What is the difference between natural and synthetic rubber?
- Natural rubber is mainly derived from the Hevea tree. When the epidermis of this rubber tree is cut open, it will shed milky juice. It is called latex, and the latex will be natural rubber when it is condensed, washed, molded and dried.
- Q: Is polyurethane and polyurethane rubber one thing?
- Polyurethane and polyurethane rubber are one thing. Because polyurethane has good resilience, it is often called polyurethane rubber, also known as polyurethane elastomer.Polyurethanes are polymerized from polyesters (or polyethers) and two isopropyl esters. Good wear resistance, followed by good elasticity, high hardness, oil resistance, solvent resistance. The disadvantage is heat aging, poor performance. Polyurethane rubber is the most widely used in automobile, shoemaking and machinery industry.Whether polyurethane should be classified as plastic or rubber depends on the actual situation.
- Q: Is it necessary to use rubber products for steel structure buildings?
- There must be a rubber cushion for the gear of the crane beam, and there is also a rubber cushion between the crane track and the crane beam. Of course, not all deformation joints are rubber, depending on how to choose the design node.
- Q: What are the bridge rubber air bags used for?
- In the use of rubber inflatable mandrel, first check the reinforcement cage wire joint and rolling head not towards the diameter direction bending, so as not to prick core mold, forming
- Q: What is the rubber composition and function of the airplane tyres?
- Polybutadiene rubber is prepared by the solution polymerization of butadiene butadiene rubber, with excellent cold resistance, abrasion resistance and flexibility, but also has good anti-aging properties. Polybutadiene rubber is mostly used in the production of tires, a small part for manufacturing cold products, cushioning materials and belt and rubber shoes. Butadiene rubber drawback is the tear resistance of the cross, wet skid resistance is not good. Isoprene rubber is the abbreviation of polyisoprene rubber. It is produced by solution polymerization. Isoprene rubber, like natural rubber, has good elasticity and wear resistance, excellent heat resistance and good chemical stability. Isoprene rubber (not before processing) strength was significantly lower than that of natural rubber, but the quality uniformity, processing performance is better than natural rubber. Isoprene rubber can be used instead of natural rubber to make heavy-duty and off-road tires, and can also be used to produce all kinds of rubber products.
- Q: What are the disadvantages of a rubber roof?
- Sunlight causes aging of rubber. Tensile strength, elongation at break, impact strength, flexural strength, compression ratio and elasticity decrease.
