Q:The difference between asbestos free gaskets and non asbestos gaskets: No asbestos gasket according to the formula, process performance and use, can be divided into non asbestos rubber gasket and non asbestos gasket, they are based on aramid fibers and plant fibers, Dengqen rubber and minerals after rolling or copying technology made of asbestos free gasket series.

Q:How do you use them? One hundredAre there any expanded PTFE gaskets in China? How about with Joe?: Expanded PTFE gaskets are truly advanced and unique materials. The utility model has the advantages of creep resistance, cold resistance, ultra-low temperature resistance, pollution free, easy installation and disassembly and replacement. Under very small preload, even under pressure change, it can withstand considerable internal pressure. It is very suitable for rough or abrasion, uneven and fragile glass surface flange, alternating temperature sealing.PTFE gasket technical parameters:PTFE gasket pressure is less than 10MPaPTFE gasket temperature are less than 250PTFE gasket density 2.1-2.3g/cm3PTFE gasket pH value 0-14Filling PTFE gasket pressure 16MPaFilled PTFE gasket pressure is less than or equal to 260 DEG CThe bulk polytetrafluoroethylene temperature is -268 DEG C and ~315 DEG CExpanded polytetrafluoroethylene pressure 21MPa

Q:What does "Q72314" in the gasket mean?: T0500 spare parts, oil pipe assembly - clutch master pump to booster -T0401 spare parts, tubing, clutch, main pump, serrated lock washer 1Q655B08, spare parts, flared through pipe fittings, 1Q72314 spare parts, gasket 1RQ.

Q:The plastic flange diameter 500, tried polytetrafluoroethylene PTFE gasket, sealing tape, but are unable to achieve the ideal sealing! Find the material that is resistant to hydrofluoric acid to be used as gasket! The test pressure is 2 kg!: With silicone rubber gasket, also can use non asbestos gasket

Q:Explosion proof thread box plus GASKET?: It is not the key to add or not to encrypt the sealing ring, mainly to see if your cable can be sealed to meet the requirements of protection and to prevent the pulling of certain torque.

Q:304 stainless steel gasket, how sealed?: so that the sealing performance is very good. You will use it in the petrochemical industry and the power industry.

Q:How about the valve gasket?: (4) when the thread sealed with teflon film with raw materials, the raw materials with the beginning at stretching and thinning, pasted on the thread surface, and then start with to get rid of excess raw material, to make the film close to the thread forms a wedge as the thread gap, generally one to two ring winding, the winding direction should be with the screw, the terminal will start at the coincidence, gradually breaking with raw material, make into wedge, so as to ensure the winding thickness, the screw thread ends before the film pressing, so that together with raw materials with thread is screwed in the screw, screw, hard to slow even appropriate, don't tighten loose, avoid the roundabout, otherwise easy to leak.

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:Is the screw hole is a through hole, to prevent leakage from the screw, need to seal, this seal gasket dimensions with the pad, screw is M8. Who sells it? It's better to send a sample link.: Copper gasket can be used to seal

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.
