Large-diameter insulated joint stock of large diameter insulated joint factory

Large-diameter insulated joint stock of large diameter insulated joint manufacturers of large diameter pipeline insulation joints is an important element in order to prevent the delivery galvanic corrosion, the implementation of the required cathodic protection of the pipeline is an alternative replacement for insulating flange factory jointly developed in conjunction with relevant institute products. It rigidity than the insulating flange can withstand bending moments, high insulation performance, long life, and underground installation. First, the main technical parameters for media: oil, gas, water, slurry, etc. 2. Applicable temperature: -40 ℃ ~ 100 ℃ 3, pressure range: PN≤10MPa 4, product specifications: DN40mm ~ DN1000mm Second, characteristics: 1 National patent product, patent number: ZL97203819.12, insulation, insulation resistance ≥10MΩ 3, withstand big moment, and pipelines strength. 4, long service life. 5, underground installation. Classification of insulation joints: a high-strength rail insulated rail joints insulating joints, it is in contact with both ends of the rail track placed side insulation, and insulation plate interposed groove on both sides of the joint, two enhanced fish plate installation a recess in the insulating plate and penetration with high strength bolts tightened holes for fitting together. The first insulating plate is slotted mesh glass cloth insulation board, between mainly used in gas transmission and distribution pipelines and gas regulator, metering, storage and other equipment, its main role is between each section of a gas transmission and distribution pipelines, equipment and between the lines are insulated isolation, to protect them from chemical corrosion and extend the service life of piping and equipment. Product complies with SY / T0516-1997 "insulating flange design technical requirements" standard. Wherein the inside surface of one of the short ends of the section to be machined to match the shape of its teeth, the sealing insulating assembly. After this short section extending end is forging forming, the formation of an integral connector. The second type of this standard clamp-type insulation joints: clamp-type insulation joints have two flanged spool, the back of which a flange is processed into a slope. Two flange contact surface, sealing and insulating ring realized by O-rings and insulation. Company Pipe products are mainly sold to petroleum, natural gas, chemicals, power, metallurgy, pharmaceuticals, shipbuilding construction and other industries, and as China's overseas engineering exports to Sudan, Pakistan, Iran, Syria, Indonesia and other countries and regions. My company is willing to preferential prices, reliable quality, advanced technology, good service, excellent work ethic, continue to cooperate with you, hand in hand, common development, create brilliant!
