Detailed description

PTFE woven aramid fiber packing

PTFE as the main material. Has excellent chemical stability, corrosion resistance, sealing, lubrication is not high viscosity and good aging endurance. Long-term work at a temperature of -180 ℃ to +250 ℃, in addition to the molten metal and liquid sodium fluoride, the ability of all other chemicals, boiling water is not from the king of change. The following are not allowed pollution is mainly used for environmental sanitary conditions, corrosive and other demanding, high-speed lines, easy to wear and other conditions.

Q: What are the production standards and quality control standards?: In what use, sealing ring of different standards, according to the use of the environment, the corresponding national or enterprise standards!!!

Q: Why can the pressure resistance of the hydraulic cylinder be increased when the PTFE gasket is placed under the Y sealing ring?: The groove of the seal is gap and will be extruded from the gap after high pressure, which will affect the sealing, pressure maintaining and durability. Therefore, when the seal needs to withstand higher pressure, increasing the PTFE is a good choice!

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: What's the difference between the gasket and the washer?: Other uses are used as spacers, springs (Baer, gasket, wave washer), wear-resistant pads, pre display devices, and locking devices. Rubber gaskets are also used on taps (valves) to cut off flowing liquids or gases. Rubber or silicone gaskets are also available to reduce vibration of the fan. Usually the outer diameter of the gasket is about two times the inside diameter.

Q: Question: a position on the sealing position of copper gasket: Copper gasket seal, high pressure resistance, oil resistance, high heat resistance, long life.

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: How do I remove the rubber sealing washer for the washer inlet valve?: but if it is often blocked I advise you to learn I simply to filter down (with a screwdriver destructively removed), save a lot of trouble, there is not much significance for water filtration net valve washing machine, it is brought to us is the dirty block, personal opinions for reference only.

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.: Use a combination pad; the outside is iron. Inside is similar to the O ring soft plastic, mounted in it, you can go to the hardware store to see.

Q: What is the material of the metal ring? And the copper pad is better than that one: The ring includes a metal ring and a rubber gasket. Metal ring anti rust treatment, rubber ring generally use oil resistant nitrile rubber or fluorine rubber. Combination pad has metric and imperial two kinds of sizes, have standard JB982-77 set combination pad metal pad plus rubber form of combination. Combined sealing washer for threaded pipe joint and sealing plug, it is generally and bayonet ring couplings used together to block the oil inlet end is mainly used for hydraulic valve pipe joint screw joint static seal face for British and American Standard thread and the French and German standard metric thread connection of the static seal etc..

Q: What effect does the flat gate of DN1200 gate valve have on the gasket?: The valve has the function of sealing gasket, gasket material selection according to the following rules: 1) with water or water is greater than 80 degrees under the conditions of using poly ethylene propylene rubber; 2) in oil and corrosion and high temperature conditions, with metal gasket; 3) in need of sound insulation and static conditions.
