Product Description:

1.Description of gasket :
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 add inner ring or outter ring.The material ring  could be carbon steel or stainless steel.

2.Features of gasket :
• 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.
•  Food processing industry.
• Hot acetic and citric etc.
Normally matrial used:
A.Steel tape:08F,0Cr18Ni9(304),0Cr18Ni9Ti,1Cr18Ni9Ti(321),0Cr17Ni12,M02(316),00Cr17Ni14M02(316L).
B.(Cold roll)steel plate for inner and outer ring:Outer ring:mild steel,0Cr13 and 0Cr18Ni9
Inner ring:same as steel t

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.
Ask 1: Why some supplier give me the price much cheaper than you?
Answer:1.They wanna attract your attention,while you contact with them,they would raise the price by any reason.
               2.They willn't provide the high qualities to you cause it had the cheap price.

Q:What's the difference between silicone products and rubber products?
Physical properties are different: nitrile rubber products waterproof, weak acid, weak base, anti oil, etc., silicone rubber waterproof, environmentally friendly, non-toxic, good elasticity, appearance, color and appearance.
Q:How long does the rubber last?
In addition, aging has ozone aging, weather aging, heat aging and so on. Ding Qing rubber is not resistant to ozone, the time is not long, it will appear aging.
Q:Is there any poison in the processing and testing of rubber products? What about the salary?
There will be some flavor at the time of processing, as well as some fillers, oil will be a little toxic, and some crosslinking agents may be toxic. But now the mixer extruder is mostly closed, so it is common to pay attention to respiratory protection.A mechanical test is usually less toxic, and a glove is enough.If you do thermal testing, such as TGA, DMA, DSC and so on, it will degrade and release small molecules, especially if the aromatic oil is filled, be sure to pay attention to.
Q:What is the size of the scorch time of the rubber?
The scorch time is often measured by scorch time. The longer the scorch time is, the less likely it is to occur early vulcanization. The shorter scorch time is, the more likely the early vulcanization occurs during the processing. The scorch time can usually be Mooney viscosity meter to determine.
Q:Bought a mouse pad, a little rubber, how to remove?
The best way is to put the balcony outside, let it go to taste naturally, generally a few days can be, do not expose to the sun, we are all solved like this.The mouse pad more or less have to taste, taste the most common cloth pad, because the part is in addition to cloth rubber, relatively the rubber is not very high, even as the high-end gaming mouse pad will have a pungent taste, which is unable to avoid, but really I don't smell in use also, not in the mood to smell, unless you put the nose close to become obvious.It is best not to wash casually or rub some potions, this will only backfire, and occasionally wash the mouse pad, you can, because the wash will be more degumming.
Q:I do rubber products, I would like to ask what metal accessories are rubber products, the specific name is what, good, then points
High pressure rubber tube, natural rubber tube, Shandong rubber tube, high pressure rubber tube, low pressure rubber tube, Ding Qing rubber tube, high quality rubber tube;
Q:What is the temperature of ordinary silicone rubber resistant to low temperature?
Because the molecular structure of silicone rubber is amorphous, the temperature has little influence on its properties, and it has good cold resistance. The brittleness temperature of the general organic rubber is from -20 DEG C to -30 DEG C, while the brittleness temperature of the general silicone rubber is between -60 and -70 degrees centigrade. When the rubber is introduced in 7.5 (mol)% phenyl, brittle temperature of silicone rubber can be reduced to -115 DEG C, remain elastic at -90 DEG C and can use.
Q:What are the ingredients in the tires?
Tires are usually composed of 3 parts of tyre, tyre, cushion belt. The inner layer of the fetus body has the rubber layer with good air tightness, and a special wheel rim is required. The structure of tire in the world has been developed in the direction of tubeless, radial structure, flat (smaller ratio of height to width of tire section) and light weight.
Q:What's the difference between a rubber track and a plastic runway? Or is it just a thing, really answer?
Plastic: plastic runway is mainly composed of carbon, hydrogen and oxygen, nitrogen and other organic or inorganic elements, the finished product is solid, in the manufacturing process is molten liquid, so can take heating to melting, the pressure makes the flow, cooling the solidification, and the formation of various shapes, this huge while the group known as the plastic material be the most changeful.
Q:How to improve the mobility of rubber material
Fully plasticated rubber use, reduce the Mooney viscosity, improve its ductility.
