Q:What are the standards for sealing gaskets? Urgently, hope you sent me in the following or recommend this standard website to me, thank you.

Gasket standards are the following: to the left to the right, | gasket standard GB/T 4622.1 - 2003 GB/T 4622.2 - Classification of spiral wound gasket 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gasket size GB/T 9128 - 2003 steel preparation of metallic ring gasket for pipe flange size GB/T 9129 - 2003 non metallic flat gaskets for pipe flanges technical conditions of GB/T 9130 - 1988 steel pipe flange connection metallic ring gasket for technical conditions of GB/T 13403 - 1992 large diameter carbon steel pipe flanges with a gasket GB/T 13404 - 1992 pipe flanges polytetrafluoroethylene envelope gaskets for GB/T 14180 - 1993 winding the type of gasket testing method of GB/T 15601 - 1995 pipe flanges with metal cladding gasket GB/T 19066.1 - 2003 flexible graphite corrugated metal gasket branch GB/T 19066.2 - 2003 flexible graphite metal gaskets for pipe flange gasket size GB/T 19066.3 - 2003 flexible graphite metal gaskets specification GB/T 19675.1 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket size GB/T 19675.2 - 2005 pipe flanges with metal punching plate flexible graphite composite gasket technology JB/T 87 - 1994 pipe flanges for asbestos rubber gaskets for JB/T 88 - 1994 pipeline flanges with metal serrated gasket JB/T 89 - 1994 pipe flange metallic ring gasket for JB/T 90 - 1994 pipe flange Spiralwound gasket for JB/T 6628 - 1993 flexible graphite composite (plate) pad JB/T 8559 - 1997 JB/T 4718 - 1992 metal gasket pipe shell type heat exchanger with metal gasket JB/T 4719 - 1992 for shell and tube heat exchangers gasket

Q:How do you use them? One hundredAre there any expanded PTFE gaskets in China? How about with Joe?

There is no substitute for gaskets on flanges

Q:What gasket does the 8MPa pressure vessel flange seal?

Standard HG20631 gasket.Seal gasket three elements: medium, temperature, pressure.If the strong acid, alkali and organic solvent temperature is not more than 230 degrees Celsius, the pressure is not more than 4.0MPa, it is recommended to 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. There are also to see the form of the flange, 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:Do you have this standard? (similar to a sealing ring in a picture)

You can refer to the following criteriaGB/T 3452.1-2005 hydraulic pneumatic O rubber seals - first dimensions: Dimensions and tolerancesGB/T 3452.2-2007 hydraulic pneumatic O rubber sealing ring second parts: appearance quality inspection specificationGB/T 3452.3-2005 hydraulic pneumatic O rubber seals - third dimensions: groove dimensions

Q:What are the production standards and quality control standards?

GB, 4848 - 1984 food container rubber washer [

Q:Question: a position on the sealing position of copper gasket

The copper gasket is generally used with thread sealing place, it is the principle of the sealing surface with two copper pad extrusion deformation, the copper pad two surface with two binding surface tightly without gap, so as to obtain the sealing effect.

Q:The engine cover, or valve cover, cylinder head cover, the cover is the engine.This is my graduation project... The NASTRAN is used, but the rest of the software is basically the same.Hope to have experienced master Zhidianmijin ah.At present, only 12 order free modal analysis is performed. The final is to do static strength, sealing. The details of the process are not clear. For example, how does the bolt hole bind? Does it hold all the points on the inside surface? What about the boundary conditions and loading? It has more than ten bolt holes, one ring gasket, and 120 0.7bar pressure inside. The material is engineering plastics.Or some people know the whole process from modeling to the results of the general steps to say, you can, thank you first. OK, add more. StopFrequency response and transient response are currently being done

What a big question you asked! I'll tell you a little about it. I hope it will help you.Let's first talk about frequency response analysis!1. study the specialized finite element mesh division soft (HyperMesh)If you have plenty of time, first learn about the finite element mesh, like Hypermesh. The mesh is pretty nice. And you'll probably use it later on,.2. establish the calculation modelGroup the mesh models into Patran, and then combine them with paste and other functions. As for the bolt hole, you can fix the inner surface. If someone asks you for a reason, you can say that the result is conservative, and that's how it works in Engineering3. detailed steps, you can find reference books.I haven't done it myself for tightness. I'm not sure about my point of view. First of all, the problem is thermal gas solid coupling. Ha ha, seems very complicated. I don't know. I understand, right?Suggest you change ABAQUS software, try it. I'm not sure. There are plenty of examples in each software that you can take a look at. The ABAQUS help file has examples of thermal coupling and fluid solid coupling. You combine these two examples to see. What might be like?

Q:It's the kind of gasket for a sanitary pipe chuck. I don't know where it is. I've been looking for it for a long time.

If it's not urgent, look at other areas. Look at what type, the Hunan history of dense rubber products company specializing in the production of sealing ring, the Internet should be able to find the product introduction.

Q:Silicone rubber gasket can withstand acid and alkali corrosion?

But the tensile strength and resistance the tear strength and poor mechanical properties of silicone rubber at room temperature, the physical and mechanical properties than most synthetic rubber, and in addition to silicone, silicone rubber, silicone rubber general oil resistance, solvent resistance is poor, so the silicon rubber should not be used for the general conditions of the occasion, but very suitable for many special occasions

Q:What kind of gasket does flange have? What standard does it have?

Flange gasket categories include: asbestos rubber pad, metal pad, PTFE pad, rubber pad, metal winding pad and other varieties.Gasket standards include:JB/T87-94 mechanical department standardsJB/T88-94 mechanical department standardsJB/T89-94 mechanical department standardsGB2502-89 Marine StandardsHG20606-97 European standards for chemical industryA flange gasket is a product of two flanges that are placed between the two flanges and then bolted to the flange so that the flange does not leak.
