SPIRAL WOUND GASKETOutstanding capability for high temperature and high pressure Automatic flexibility and recovery from the change of temperature, pressure, vibration and working conditionsEfficient production for any type of dimensions such as round or oval type, etc.Outstanding sealing capability as it is produced according to the pressure of unbalanced flange. Hoop and Filler materials can be selected according to special operating conditions. GRAPHITE MOLD PACKING â?¢ Graphite Tape Packing is the packing that compressed and molded in a certain dimension for easy installation. â?¢ The graphite's self-lubrication capability and low coefficient of friction allow to use in a wide range without giving damage on the reciprocating and rotary shaft. â?¢ If you want to disassemble only gland without disassembling pump and valve, you can just cut it and deliver. â?¢ You can get better sealing effects if you use with ALS910C, ALS900G and ALS955W depending on the use purpose. RING JOINT GASKET Ring joint gasket is a type of pressure energized gasket used on pipe flanges, pressure vessels, Valve bonnets handling, high pressure steam, gas, hot oil, solvent vapor at high temperature. DONGSUHs experienced technology offers many different types so that customers may select the most suitable one in accordance with operating conditions. MECHANICAL PACKING (VARIOUS MODELS DEPENDING ON CONDITON) PTFE V-PACKING SPRING ENERGIZED SEAL
Approx. Price: Rs 90 / Unit We are a highly acclaimed name in offering best quality Champion Gaskets And Packing Materials.
TECHNICAL DATA - Tensile Strength : 28 ~ 35 MPa - Elongation : 200 ~ 400% - Temperature : up to 500°F (260 C) - Hardness : R25 (Rockwell) Application - Control valves, Rod, piston FEATURES - Elimination of costly seal failure or blowouts - Reduced installation costs - Reduced equipment downtime with exact seal specifications - Reduced inventory costs - Lower friction / Friction a measurement of the resistance to sliding between a seal and hardware surfaces, is directly related to seal material coefficient of friction and the total load. - Longer Life / Individual sealing rings expand under bolt loading to maintain a tight, virtually leak proof set with up to 50% longer services over braided styles.
Spiral wound gasket Got-400 spiral wound gasket is accumulated, hovered and wound, and spot welded beginning and end terminal by v-shaped or w-shaped stainless steel and non metal filler, which has good compression elasticity, and is suitable for the sealing parts with temperature and pressure altering violently. It is a static sealing parts used for such flange connecting joints as pipeline, valve, bump, heat exchanger, tower, manhole, and hand hole, etc. It is widely applied in departments as petrochemical, mechanical, electric power, metallurgy, boat building, medical, atomic energy, and aerospace
Kammprofile gasket Got kammprofile gasket , generally processed to be concentric groove in the two faces of the stainless steel flat gasket by precise lathes. According to the different medium, w can choose flexible graphite, ptfe, non-asbestos, or other soft metal, to sick to the two faces of the gasket. It can directly be used without sealing layer, and the effect is good. But under the high pressure occasion, it will be easy to do damage to the surface of the flange. 410 basic type kammprofile gasket 410l kammprofile gasket with outer ring (integral type) 410lm kammprofile gasket with outer ring (split type) Model 410lm split type metal toothed gasket with outer ring, can choose richer metal, e.G. Carbon steel, as the outer ring, and the outer ring thickness can be 1.5mm, more flexible and economic than the integral type 410l, and the lining metal can be repeatedly used. Product application: Got toothed combination gasket is the first choice gasket under relatively low preload power, the soft surface of the sealing layer can avoid the direct touch between metal and metal, which is combined reliably and compactly, to protect the metal flange from damaged, even under extremely high load. The toothed combination gasket is especially suitable for the flange connection in thermal exchanger, container, and reaction vessel under high temperature, high pressure, and the working condition altering occasions. It is an ideal substitution for traditional metal jacketed gasket. Operating pressure range: 6.4~25mpa
Reinforced graphite gasket
Double jacketed gasket Product application: Got is particularly suitable for heat exchanger, gas pipeline, cast iron flange, cylinder head and boiler, and other containers. Generally, when installed, it can press the initial thickness of the gasket to get a 30% deformation, thus can effectively seal the unevenness and small defects of the flange. Through choosing different metal and different fillers, it can suit to different mediums.
Kammprofiletm gasket is the preferred gasket when improved performance at low seating stresses is required. It features excellent anti-blow-out properties linked with the reliably of a solid metal-to-metal seal combined with a soft sealing face to provide a tighter joint. It is particularly suitable for applications where high temperature, pressures and fluctuating conditions are encountered. Non-metal cover layers ensure that flanges are not damaged, even at extreme loads. This gasket is an ideal replacement for problem applications associated with jacketed gaskets, for heat exchangers, vessels and reactors and various flange connections. Pressure: (6.4~25mpa) Other items in : gasket kammprofile gasket corrugated metal gasket Materials for the faces: Flexible graphite, ptfe, non-asb, etc. Normal with thickness 0.5 mm
Spiral wound and connected its end and beginning by dot welded. Depend on its excellent compression resilience it is suitable for sealing spots where the alteration of temperature and pressure are frequent. It can be used as the static sealing element of pipe, valve, pump, thermal exchange, condensing tower, plain hole and man hole of flange, etc. It has been widely applied in the fields of petrochemical, mechanical manufactory, power station, metallurgy, shipbuilding, medical and pharmaceutical nuclear power station and navigation, etc. Other items in : gasket spiral wound gasket » inner and outer ring of swg On request
Spiral wound gasket Spiral wound gasket is the best in the compression resilient in all the half-metal seal gasket, which is made by the metal hoop band and different kinds of packing material. We can make its structure density according to the demand of different locking force, and we use the inner and outer circle to control the maximum compact degree. So it can be well suit the rough flange face, especially suit the situation of unbalance load, loose of joint force, temperature and pressure change periodically , concussion and shock. It is used in flange joint of valve, pump, heat exchanger, tank, and handhole. It is widely used in the fields like petrochemical industry, machine, electric power, metallurgy, ship-building, medicine, atomic energe, space navigation. We made spiral wound gasket conform to different standards, for example, asmi, bs, jis, din and several other criterion used in china. Item no.
