Q:BMW X5 engine gasket oil permeability to the engine to add what gasket is sealed: 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

Q:Silicone rubber gasket can withstand acid and alkali corrosion?: Silicone rubber has excellent heat resistance, cold resistance, dielectric properties and ozone resistance and ageing resistance properties, outstanding performance of silicone rubber is the use of wide temperature, at -60 DEG C (or lower temperature) to +250 DEG C (or higher temperature) under long-term use.

Q:Why don't gaskets use metal gaskets in general?: According to the material can be divided into metal gasket and non-metallic gasket.Metal with copper gasket, stainless steel gasket, iron gasket, aluminum gasket and so on.Non-metallic asbestos gasket, non asbestos gasket, paper gasket, rubber gasket and so on.

Q:Can marine sealing gaskets be made of asbestos gaskets?: Asbestos gasket is a very good gasket, but because it is listed as a strong carcinogen, most countries in Europe and America have banned the use of asbestos gasket.

Q:What sealed products are used in refineries?: Metal gasket with outer ring is especially suitable for occasions with uneven load, easy loosening of joint force, periodic change of temperature and pressure, shock or vibration. It is the static seal of valves, pumps, heat exchangers, towers, Manholes, hand holes and so on. It is widely used in petrochemical, mechanical, electrical, metallurgical, shipbuilding, pharmaceutical, nuclear and aerospace industries. The metal graphite gasket is made of stainless steel band and flexible graphite band. Main application: used in the steam, oil, gas, solvent, gas, heat transfer medium and so on contact the pipeline, the valve, the pump entrance and exit, each kind of heat exchanger, the reaction tower, the observation hole, the hand hole and so on part seal. Also, give a material for your research. The sealing material types and application of temperature and pressure seal sealing characteristics of note temperature are less than 80 in low pressure resistant oil resistant asbestos asbestos medium aramid sheet non asbestos sheet flat gaskets for pipe flange interface, water, gas, oil, acid and dilute liquid asbestos material has become obsolete, is not recommended to increase the use of rubber gaskets with skeleton under pressure, hydraulic pressure move among force and soft sealing, wear resistant parts available polyurethane products resistant PTFE flat gasket outsourcing low pressure under the condition of strong corrosive medium temperature less than 120 DEG -260 DEG high pressure resistant rubber and Ding Qing seal, all kinds of V, U, Y type O type ring, under high pressure hydraulic sealing rubber products Gabriel.

Q:What gasket does the 9.8MPa pressure vessel flange seal?: What gasket is used for the flange of the 9.8MPa pressure vessel, and what form of flange shall be used to determine the gasket after determining the diameter and temperature of the vessel (and the nature of the medium)?. If the vessel diameter is relatively large, coupled with the 9.8MPa (or small), should adopt the self sealing flange, using triangle aluminum sealing pad, or use such as relatively small diameter, it should adopt the concave convex type or tenon form flange, is copper or aluminum flat gasket commonly used.

Q:What's the difference between the gasket and the washer?: Gasket (washer) is thin (usually circular) a vulnerability (usually in the middle) is usually used for load distribution of the thread fasteners, pad between the connecting piece and the nut parts, generally flat shaped metal ring.

Q:Metal winding gasket, metal tooth shaped gasket, reinforced graphite gasket, metal coated gasket, thank you prawns: There are many types of customers, and all factories that use pipelines, equipment, transportation and handling of certain process media can be final customers. There are many ancillary equipment manufacturers. The owner of the new project, the Design Institute, the construction side.

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: Usually pressure is not required for environmental protection, generally can use asbestos oil resistant gasket.

Q:Is the raw meal belt not used to prevent leakage between the pipe and the pipe? But I see a lot of water heaters only at the cold water outlet (into the water heater and faucet at both ends) wrapped around the raw meal belt, and at the hot water outlet (shower) is not entangled, just put two pads. Is it okay to tape the raw material at the hot water outlet? I put two pads, and a little water seepage, can you put one more? What is the function of rubber pads? Under what circumstances do you need to use raw meal belts and pads? Thank youIn the picture, the middle pipe is hot water outlet (without wrapping the raw material belt, only two pads are placed), and the right side is cold water outlet (wrapped with raw material belt).: Because the nut is tightly into the hot water outlet type, in the process of tightening the nut and bolt the clamping pad, thereby, seals play a role, as long as the stud is long enough, put a line, two would be easy if you Water Leakage, wrapped with raw materials, it will cause the nut a tight end, not to pad clamping, so it is more likely to be Water Leakage.In terms of hard and soft connection, it is hard to connect with raw material and soft adhesive pad!Different uses, but the same effect,
