Detailed description


Aramid fibers woven PTFE 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:SUPOR electric pressure cooker sealing ring plastic frame quality problems, broken, in Laixi, Laiyang where to sell?
You can check the local SUPOR customer service phone, and then you put the pot model to tell him, he will help you to check there is no such thing, if the insured need to spend money to buy, if they do not have, you can get them to you from the factory into our own expenses, the premise is your home a pot over the shelf the local SUPOR phone you can find to buy a pot with SUPOR national customer service service table, there is
Q:What is the difference between the sealing ring and the dust cap on the bearing?
Dust cover: an annular ring made of thin metal plates, fixed to a ring or washer of the bearing, which covers the inner space of the bearing but does not come into contact with the other ring or washer.
Q:The outer ball tooth ring sensor mud suede cover gasket what use to send
The elastic loading mechanism and the auxiliary seal are the mechanical seals of metallic corrugated tubes, which we call metal bellows seals.
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:Installation requirements for gaskets
4, when sealing gasket is pressed, it is better to use torque wrench. For large bolts and high strength bolts, it is better to use hydraulic tightening devices. The tightening torque shall be calculated by calculation according to the given gasket. The size of the hydraulic pressure of the hydraulic tightening device shall also be determined by calculation.5. When installing the gasket, tighten the nut in sequence. However, the design value should not be screwed once. Generally should be recycled at least 2~3 times so that the gasket can be evenly distributed.6, the flammable and explosive medium pressure vessel and piping, replacing gasket should be used to avoid security tools, tool and flange bolts or collide, sparks, causing a fire or explosion accident.7, if there is leakage of the pipeline, it is necessary to reduce the pressure, then replace or adjust the installation of gasket, strictly prohibited with pressure operation.
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.
Q:What is the function of the washer between the end cap and the case?
1, the role is to cushion the amount of thermal deformation reserved.2 gasket refers to the pad between the connecting parts and nuts. A generally flat metal ring used to protect the surface of a connecting piece from the scratch of the nut and to distribute the pressure of the nut on the connecting piece.3, the gasket is divided into: -C, flat washer washer -A and grade C, grade -C large washers, washer, flat washer, flat washer, chamfered - - a grade steel structure with high strength washer, spherical washer, taper washers, square taper washers, steel I-beam with square taper standard type washer, spring washer, spring washer, light heavy spring washers, lock washers internal teeth serrated lock washers, inner and outer teeth lock washers, serrated lock washers, single ear washers, ears washers, external tab washers, round nuts with washers.
Q:What about the non asbestos gasket in Chinese market?
In view of this particular case, we hereby reaffirm that all the gaskets we operate are asbestos free gaskets without any asbestos content. Unless otherwise specified, it will be explained in detail.
Q:How to make a faucet washer?
The faucet gasket is silicone.Silicone (Silica gel; Silica) alias: silicone rubber. Is a highly active adsorption material, belongs to the amorphous substance, its chemical formula is mSiO2. NH2O. Insoluble in water and any solvent, non-toxic, tasteless, chemical stability, in addition to strong alkali and hydrofluoric acid, do not react with any substance. Different types of silica gel have different microporous structures because of their different manufacturing methods. The chemical composition and physical structure of silica gel determine that it has many characteristics which are difficult to be replaced by other similar materials: high adsorption properties, good thermal stability, stable chemical properties, high mechanical strength, etc..Silicone rubber with high temperature resistance to ozone and prominent, weather resistant performance, using its unique elastic and ozone in the temperature range -70 ~ 260 degrees of internal energy, weather resistance and other advantages, suitable for the production of gasket.
Q:What material is good for sealing gasket of steam pipe?
if it is oil, see what is there, such as phosphate oil, then use the fluorine rubber,
