Q:What material flange gasket is better on the steam pipe?
I hope it doesn't work as a metal.Answer three: metal coil gasket Y value is 10000psi, non-metallic flat gasket Y value is generally between 1500-4000psi. So, not all flanges can be optionally changed into metal wound gaskets. But can we recommend metal serated gasket, such as metal serrated gasket GARLOCK Y value is only 1000PSI, so the use of non metallic gaskets can be used where basic metal serrated gasket, and the sealing performance of metal serated gasket spiral wound gasket is much better than.
Q:What are the flange gasket materials?
Plastic: PTFE most commonly used.Metal: all kinds of corrosion-resistant metal winding pad, according to different media configuration.
Q:That's good. I know that. I just don't know what the machine is made of. Can you explain it in detail?Chasing the answerThere is a press, you go to the machinery factory to ask, you know
Non asbestos gaskets required for environmental protection.Metal gaskets or semi metal gaskets can be used for more pressure.
Q:Gasket standard
1, GB4622.2-93 spiral wound gasket pipe flange size series 2, GB9126.1-88 plane type steel pipe flanges with asbestos rubber sheet, 3 GB9126.2-88 convex type steel pipe flanges with asbestos rubber sheet, 4 GB9126.3-88 bump with asbestos rubber sheet surface of steel pipe flanges and look at the details of reference seal mechanical seal technology network network
Q:How long can I use the PTFE gasket?
Specific, you can find Teflon manufacturers to cooperate with each other, repeatedly proofing, if not satisfied, modified and then proofing, until a satisfactory performance of a variety of ptfe.
Q:What gasket does the 9.8MPa pressure vessel flange seal?
Seal gasket three elements: medium, temperature, pressure. What's your medium? Is it sour or base, organic solvent or water vapor? How high is it? How much pressure? In the gasket selection. If the strong acid, strong alkali and organic solvent temperature is not more than 230 degrees Celsius, the pressure is not more than 4.0MPa, I suggest you use PTFE gasket. If high temperature and high pressure water vapor, that is, high temperature, no more than 600 degrees Celsius, the pressure at 25MPa, it is recommended to use metal wound gasket. Of course, there are also to see your flange form, and there is the implementation of which country standards. Because of this gasket a lot, the most important thing is to choose suitable for their use of gasket. The seal is small, but the role is very, very important. But don't get obsessed with foreign brands, either. In fact, many are produced in mainland china.
Q:What is the difference between the sealing ring and the dust cap on the bearing?
Seal ring: ring formed by one or several parts of the cover, fixed in a ring or a washer bearing and another ring or gasket contact or the formation of the labyrinth of narrow gap, to prevent leakage of lubricating oil and foreign matter. Beijing's got all the attention Boyun ring and dustproof cover seal.
Q:Rubber gasket
You can search the Chinese American rubber product inspection standard list from the Internet, and then according to each description, you can find what you want. The standard is a lot.
Q:Can gb/t97.1 be used for sealing?
GB/T 97.1-2002 flat washer level aThis standard specifies the nominal specifications (thread diameter) for 1.6 ~ 64mm, standard series, hardness class 200HV and 300HV grade, product level is a class of flat washers.
Q:BMW X5 engine gasket oil permeability to the engine to add what gasket is sealed
That shouldn't be the case for BMW. The reason is that the engine gasket aging to save money, buy a few barrels of good imported sealant, generally between 15-30, directly to the sealant gasket in the original position on a line, you can also get down, look like shape forming, with the original car mat. Note that buy bad glue, yes
