Q:Why don't gaskets use metal gaskets in general?

According to the material can be divided into metal gasket and non-metallic gasket.Metal with copper gasket, stainless steel gasket, iron gasket, aluminum gasket and so on.Non-metallic asbestos gasket, non asbestos gasket, paper gasket, rubber gasket and so on.

Q:What is the basis for the classification of gaskets?

Look at what occasions, what environment, what media, what pressure, what temperature to develop a variety of different gaskets

Q:It is urgent to have a spring self sealing ring. The detailed parameters will be listed in picture form, and the quality will be better

Spring self sealing ring, such as parameters: outer diameter 36mm, the internal diameter of 21mm, you know the line diameter is 2.5mm; height is 8mm, please ask the number of turns or the pitch is? You'd better attach a physical map.

Q:What's the difference between a sealing washer and an elastic washer?

As far as the distinction is concerned, from the model point of view, the O ring has a fixed model name. For example, 3.1*50., and gaskets have fixed models, such as oil seals, 45*60*7.

Q:Gasket free sealant

I don't know what you want to ask. Gasket free sealant is usually a room temperature curable one component silicone sealant.

Q:The sealing principle of metal wound gasket?

Sealing principle of metal wound gasket:The sealing surface when the pressure load, to produce compressive stress, can improve the sealing contact surface, when the stress increases enough to cause the surface of the plastic deformation obviously, it can fill the gap seal cover, plug leakage channel. The purpose of using metal wound gasket is to use the gasket material to produce plastic deformation easily under the action of pressing load, so that it can fill up the tiny and uneven surface of the sealing surface and realize the sealing.Extension of knowledge point:Metal wound gasket is a sealing gasket is used widely at present, in order to return to the best elastic gasket semi metallic gasket, by V or W shaped steel strips with various fillers alternately wound together, high temperature, high pressure and adapt to the use of ultra low temperature or under vacuum conditions, by changing the gasket combination of materials, can solve the problem of all kinds of chemical corrosion medium on the gasket, the structure density can according to different requirements to lock force production.

Q:Why is copper gasket always leaking out of the sealing surface?

The sealing surface of two different material substances in contact is generally cast iron, cast iron due to the thermal expansion coefficient of copper with different period of time when the heating operation of the equipment, will not leak in a short time, but when the device stops again after operation will be oil leakage.

Q:What are the advantages and disadvantages of those materials and materials used in the air compressor GASKET? FiveIncluding a number of commonly used non-metallic gaskets, what is the specific material name?

Aluminum gasket: cheap, no copper gasket, durable.Copper gasket: high price, durable. After the use of a fire baking, you can continue to use.

Q:What are the flange gasket materials?

For high temperature, corrosion resistant occasions.Graphite: used for high temperature, strong corrosion occasions.

Q:Gasket, packing belongs to the scope of mechanical seals?

Gaskets and packings are sealed, but they are not mechanical seals
