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: The material column of some gaskets / gaskets indicates what "200HV" means Is that the hardness scale? What materials are usually used? Know the elders please advice, little brother is not very grateful!!! []: Should be less than 200HV, this is the gasket, should consider the tightness, hardness, sealing is not good!

Q: Can the metal gasket face seal reach 100MPa?: The gasket standard is mainly the following: first, the standard GB/T 4622.1 - 2003 gasket spiral wound gasket classification GB/T 4622.2 - 2003 spiral wound gaskets for pipe flanges size GB/T 4622.3 - 1993 GB/T 9126 specifications of spiral wound gaskets for pipe flanges - 2003 non metallic flat gaskets size GB /T 9128 - 2003 steel pipe flanges with metal.

Q: What are the flange gasket materials?: Plastic: PTFE most commonly used.Metal: all kinds of corrosion-resistant metal winding pad, according to different media configuration.

Q: such as metal winding gasket, flexible graphite composite pad, metal gasket, asbestos pad and so on. 10Ask again, how much money does it cost to ask so many devices?: The metal pad 1500 a small winding machine, spot welding machine open graphite 500---4000 block, 1500----5500 block, composite pad double shear machine 5000 blocks, 1500 blocks of single shear machine, coating machine 8000 pieces about such a price, do the math.

Q: What kind of material is rubber gasket?: The rubber gasket is a self expanding sealing gasket, belonging to the sealing component of the pipeline. The gasket is composed of an outer ring, the middle ring and the inner ring expansion of three parts; the outer ring and the inner ring is generally elastic sealing ring, the middle ring at the center of a ring on both sides of the bubble structure, hollow ring, outer ring seal ring outer ring and the inner side of the opening; the inner ring is divided into two parts installed in the middle, inside and outside the ring structure of the global expansion. There are many kinds of rubber gaskets, and the materials used for rubber gaskets are different. For example: if it is used in mechanical seals, generally need high temperature, oil and corrosion resistant materials, and if used in the food industry, you need more environmentally friendly, pollution-free material. Rubber gasket material is generally divided into: silicon rubber gasket, butyl rubber seals, nitrile rubber gaskets, silicone rubber gasket, three EPDM gasket, chloroprene rubber seal, polyurethane rubber gasket, hydrogenated butadiene acrylonitrile rubber gasket, fluorine rubber sealing pad of the 9 kinds of material. The above-mentioned 9 kinds of rubber gasket material has its own characteristics, so its use is also different.

Q: IFG-5500 what's the material in the gasket?: Detailed description of the business opportunities:AdvantageSeal more closelyThe inorganic fiber gasket provides exceptional thermal stability with minimal weight lossReduced creep relaxation and increased torque retention force provide optimum sealing performance

Q: How do you use them? One hundredAre there any expanded PTFE gaskets in China? How about with Joe?: Gore is just a world - famous company,Polytetrafluoroethylene PTFE material is composed of 100% after special processing and manufacture, with excellent flexibility, excellent adaptation property and molding ability, and has high tensile strength, creep resistance, temperature resistance, corrosion resistance, aging resistance, cold flow. Can not bad long-term storage, no pollution, and is composed of multi direction fiber countless homogeneous fine soft tough, high density fibrous tissue with unique, compressed fiber will become more closely intertwined, uniform, airtight, waterproof, sealing performance is good, in severe corrosive environment and high temperature also, can maintain excellent sealing state.The material is suitable for low pressure sealing applications. It can be used as a highly sealed and highly corrosive environment for biological pharmaceutical, food, chemical, refining, military, marine, aerospace and mechanical industries. Heat exchanger, FRP, compression frame flange, steam container flange, liquid and gas system, water system, ventilation fan rack and other construction sites.Durability, weather resistance, high safety, used for industrial leak sealing.Main technical parameters:Density (Density):1.0g/cm3Pressure (Pressure) < 4.0MpaTemperature (Temperature) -100~200 DEG CPH value (PH range) 0-14

Q: Do you have this standard? (similar to a sealing ring in a picture): You can refer to the following criteriaGB/T 3452.1-2005 hydraulic pneumatic O rubber seals - first dimensions: Dimensions and tolerancesGB/T 3452.2-2007 hydraulic pneumatic O rubber sealing ring second parts: appearance quality inspection specificationGB/T 3452.3-2005 hydraulic pneumatic O rubber seals - third dimensions: groove dimensions
