Q:What's the meaning of "200HV" in the material column of washer / gasket?
The material column of the gasket / gasket indicates that 200HV is material and the mechanical grade is steel 200HV.Examples of marking: standard series, nominal size d=8mm, performance rating 200HV, plain gasket without surface treatment: gasket GB97.1 - 858 200HVA part that is attached between a connecting piece and a nut. A generally flat metal ring used to protect the surface of a connecting piece from the scratch of the nut and to distribute the pressure of the nut on the connecting piece.
Q:Is double layer gasket better than equal thickness single layer GASKET? Twenty
Should be in the same preload, the gasket between the compensation of each other, more conducive to liquid sealing.From another angle, the pressure is higher, or the temperature is higher. In this case, with two gaskets, the two pads increase the chance of leakage due to the poor wear of the gasket in harsh conditions.You mentioned home pressure manhole covers use two pieces, because he is mainly used for sealing air and water, the environment and medium simple, while some of the industrial standards of the time limit. I am impressed, the home of the pressure covers also used waste tires, cut the gasket.However, in terms of sealing effect, it is generally not recommended to use both sides of the gasket. The effect of the monolithic shim is superior to that of the double wafer.
Q:How much pressure can the aluminum gasket bear?
Silicone rubber gasket (WMQ): silicone rubber is based on poly two silicone (silicone polymer) as the main raw material.
Q:What gasket does the 8MPa pressure vessel flange seal?
What a big flange. The gasket is estimated to be out of order and easy to spread. It is recommended to use a toothed gasket. This technique is very mature. It is specially designed for large flange sealing. The effect is almost the same as that of the wrapped gasket!
Q:What's the difference between the sealing ring and the gasket?
For example, belts are divided into A, B, C, D, O belts. In fact, it is used for sealing. Usually you go to the seller's shop and he can help you figure out what you need. Not as good as uncertainty, preferably with drawings or objects in the past to buy.
Q:304 stainless steel gasket, how sealed?
Therefore, the 304 stainless steel gasket made of this material, it is generally in the case of metal winding pad, in the 304 stainless steel wrapped on a layer of graphite material or PTFE material,
Q:Hydraulic joint with copper and aluminum gasket than rubber gasket will be more durable, sealing performance will be better?
The metal pad before using the best grinding, long time use is also good, but now the popular seal combination, inside is rubber, the outer ring is a metal skeleton, but also the price is disposable, and metal pad almost.
Q:How long can I use the PTFE gasket?
There are also many varieties of ptfe. To improve the performance of the molding process is the production of modified PTFE, such as carbon fiber modified PTFE is a classic high strength, high wear resistance, creep resistance of a variety.
Q:Engine oil tank seal is not strict, how to do the oil spill?
Remove, clean, change the gasket from new to good, otherwise it is not used, or will leak,
Q:Where is the three yuan catalyst sealing inspection machine?
Three yuan catalyst special sealing inspection machine should not sell, domestic can produce three yuan catalytic converter manufacturers can be counted, so even if there is the production of this equipment manufacturers, a year also can't sell several units;
