Shanghai Songjiang oil pump dedicated professional manufacturing rubber joints

Oil-resistant rubber joints are reinforced by a fabric and flat-shaped pieces of rubber wood joints, loose set of metal flange or threaded pipe flanges, used in pipe vibration noise reduction, compensation displacement connector. It is a highly flexible, high air tightness, chemical resistance and weather resistance of the pipe joints. Divided by shape: Concentric other tracks, concentric reducer, eccentric reducer. According to the structure is divided into: single ball, double ball, elbow sphere. By connector into: flanged, threaded, threaded pipe flange connection. By work pressure points: 0.25MPa, 0.6MPa, 1.0MPa, 1.6MPa, 2.5MPa five grades. Since the rubber oil resistant rubber joints with good sealing properties, it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial, refrigeration, sanitation, plumbing, fire protection, electric power and other infrastructure projects. Senior water use oil and rubber joints, the pipe must have a fixed support or mounting bracket, otherwise the product should install anti-pull-off device. Fixed support or bracket force must be greater than the axial force, otherwise it should install anti-pull-off device. Medium: Depending on the material can be made according to acid, alkali, corrosion, oil, heat and other species to adapt to a variety of media, and environmental connections: Usually there are threaded, flanged, clamp connections and so on. [1] oil and rubber joints Material: oil rubber joint ball is from the inside layer, enhanced multi-layer plastic scraping nylon tire cord fabric, rubber outer layer composite tubes. According to different temperature of the oil, used oil and rubber are also different. Nitrile rubber (NBR) of butadiene and acrylonitrile copolymer. Characterized by resistance to gasoline and oils of aliphatic hydrocarbons are particularly good performance, after polysulfide rubber, acrylic rubber and fluorine, and superior to other general rubber. Good heat resistance, air tightness, wear resistance and good water resistance etc., strong bond. Features: 1, small size, light weight, good flexibility, easy installation and maintenance. 2, can produce lateral, axial, angular displacement, from the heart barrier pipe, flanges, not parallel to the limit during installation. 3, can reduce the structure-borne noise at work, strong vibration absorbing capability. Oil-resistant rubber joints specific classification: JGD-type flexible synthetic oil and rubber joints, JGD-A type can be curved flexible rubber with double ball joints, JGD-A1 type reinforced with double ball can be curved flexible rubber joints oil, JGD-A2 type available Flexing double wire connecting oil and rubber ball joints, JGD-B-type elastic tube shock absorbers (Reducing joint), JGD-C oil-type fan coil rubber joint, JGD-D-type rubber isolation pads, WTX type flexible synthetic rubber elbow, ZT, ZTB, ZTG spring vibration damper, HTXDJ elastic hanger. Rubber in oil easy expansion, ordinary rubber with only a period of time at temperatures below 80 degrees. So it has been the hot oil and rubber joints rubber joint manufacture raw materials selection problems. The main rubber oil resistant rubber joints of nitrile rubber, and nitrile rubber with excellent oil resistance, oil resistance after its polysulfide rubber and fluorine rubber, and has a wear resistance and air tightness. Polar nitrile rubber is very strong, and compatibility with other polymers in general is not very good, but, and neoprene, modified phenolic resin, PVC and other polar polymers, in particular, and chlorine polymer has good compatibility, often performed with. In addition, to improve the workability and performance, nitrile rubber is also often associated with natural rubber, styrene-butadiene rubber, butadiene rubber and other non-polar rubber and use. It should be pointed out: the characteristics of NBR is oil resistance, with other polymers and with (other than PVC) have reduced oil resistance, there is a tendency.
