Detailed description

Kevlar Braided packing

With aramid fiber as the main material, repeatedly dipping lubricants, lotions and other precision PTFE compiled. There is preferably a high resilience, chemical resistance, low cold flow and high line speed, and the comparison with other types of packing, the crystallization medium and the particles can resist higher temperatures. Can be used alone or combined with other packing. Mainly used for multi-media particles, easy to wear conditions.

Q: Filter replacement did not find a small ring, so there is no problem for the filter: Hai Yu filter tells you, friend, that's a big problem. Is the filter closed and the sealing ring not leaking? Generally, the filter has a sealing ring. If you use the old machine to filter the sealing ring, it is recommended to change immediately, the sealing ring will be aging, easy to crack, oil spills.

Q: Pictured above, the red circle is directly in the processing of A plane with PTFE gasket compression seal, but always leak, I think it is in the corner due to leakage when processing make fillet PTFE gasket is not very good and fit to face A. Now I want to processing into the structure shown below, put a circle at the corner where the processing tank, which can fit the PTFE gasket A good surface, but also not to experiment, did not know that it is okay, there is no expert advice!The main problems are as follows:First, is this the cause of the leak?Second, A surface in processing, roughness and flatness should be processed to how much more appropriate?Third, how about the tolerance of key dimensions?: PTER material itself is less elastic, which requires the design and manufacture of groove are more accurate.Please provide me with drawings and exact requirements, and I'll give you a plan. Guarantee feasible.

Q: Which kind of plate heat exchanger has the highest cost performance?: Snap fastener type rubber pad, rubber pad, rubber pad buckle type, convenient installation and disassembly, most models of AI is Reed ARD, he is good.

Q: Gasket is a kind of machinery, equipment, pipes and other internal sealing materials, which types are there?High and medium pressure asbestos rubber sheet gasket, oil asbestos rubber gasket, cylinder gasket, aramid gasket, non asbestos plate gasket, asbestos pad, PTFE lining rubber pad, I know that, there are other ones?Can anyone tell me what their scope of application is?: The new organization dense, molecular structure of non-polar, used as a gasket, contact surface can be smooth, the metal flange is not sticky. In addition by molten alkali metal and containing fluorine gas erosion, which is resistant to many kinds of acid and alkali, salt, oil solution of corrosive media. PTFE gasket including pure PTFE, PTFE or PTFE expansion. The semi metallic gasket (also called metal gasket). Non metallic material has good flexibility, compression and bolt load ability is low. But it is mainly to determine the strength is not high, poor elasticity, not suitable for high pressure temperature. So the combination of metal materials with high strength and good elasticity. Withstand high temperature characteristics. The formation structure is semi metal gasket. The gasket. Semi metal gasket are mainly metallic gasket, metal winding gasket, corrugated metal gasket, with metal serrated gasket with the metal. Gasket (metal gasket). The gasket to nonmetal material core, thickness of sheet metal 0.25-0.5mm outsourcing. According to the state of coating can be divided into coating, coating, coating and half wave Double coated sheet metal. According to the elastic-plastic material, heat resistance and corrosion resistance were selected. Mainly copper, galvanized iron, stainless steel, titanium, Monel alloy. It is widely used in copper, galvanized iron, stainless steel.

Q: Method for using gasket free sealant: Remove the greasy dirt, moisture, rust and dust on the glued surface, and keep the bonding surface clean and dry;Apply the glue to the surface of the adhesive and coat it into an unbroken rubber ring (which needs glue around the screw hole);The airing glue is about 10 to 15min. After the table is dried, the bolt is fastened and fastened according to the requirement of use;After the glue, should be placed more than 24h, after the glue curing, forming an elastic gasket.

Q: What kind of hardness is used to measure the hardness of gaskets, gaskets, gaskets and O rings?: It's all rubber, but if it's Shaw's hardness tester, but you'll have to figure out Shaw's hardness tester. There are two kinds of HA and HD, one is soft rubber, one is hard rubber, and that's what you look like!

Q: 304 stainless steel gasket, how sealed?: Hello, 304 stainless steel ring gasket if made, the sealing performance in general, sealed liquid should also improvise, but the sealing gas on the more difficult.

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: If the double gasket 1mm per piece, and the single layer gasket 2mm, which sealing effect is good? Is there any basis? I remember that the pressure wells in the family used double layer gaskets to solve the problem: Double layer and single layer gasket sealing problem can not generally say who is good, who is not good. This is closely related to the material of the gasket and the medium, pressure and temperature in the sealing chamber.For example, the pressure is atmospheric pressure, the medium is a liquid fluid, the problem is within 200 degrees celsius. Most of the material can accept this temperature, so at this time, generally two pieces of gasket sealing performance better.

Q: The difference between asbestos free gaskets and non asbestos gaskets: Because no asbestos gasket series not only has high strength, but also has good resiliency, and has strong anti permeability, therefore they are excellent environmental protection in automotive and industrial machinery replacement of asbestos gasket gasket.
