the best insulation connection

1.matching product is between two pipeline. it is save and easy to install. 2.ISO9001:2000

YY series insulation joint purpose: buried steel oil, gas, water pipeline often due to corrosion and damage, not only reduce the life, serious when still can cause accidents.To prevent the buried pipeline corrosion is to take effective measures to cathodic protection technology.In the cathodic protection project, asked to be protected pipe and the connected some devices, equipment, branch room to cut off the electric connection, avoid negative level protection current lost to the don't need protection parts connected.To ensure the success of the cathodic protection technology.Insulation joint with requirements of buried steel pipeline sealing performance, strength properties and electrical method for corrosion insulation performance of the pipe joint collectively.It contains assembly, insulating plate, filler, seal ring, nozzle stub, etc.It is insulation flange replacement products.Structure characteristicsThe whole insulation joint extrusion welding form, and shall not use bolt, flange connection type.Insulation joint with insulation and sealing material sandwich and fixed in sleeve (assembly) to form within.The whole insulation joint, to the internal components should be secured in the corresponding position.In the soil pressure, the rules of pipeline operation pressure and factory or field to water pressure test, the insulation joint is maintained.Insulation joint sealing element in the joint internal abut insulation board, have permanent to elastic, and both sides of the potted component touch directly the naked surface of metal without moving, keeping the compactness of joint property.Product featuresInsulation performance is good: 2500 v shaking table test insulation resistance was 200 m old one, breakdown voltage or 3 kv.
