insulation connection

1.high quality 2.low-cost 3.provide good service   matching product is between two pipeline. it is save and easy to install.                                                                

YY series insulating joint use: steel oil, gas, water buried pipeline due to corrosion and damage, not only reduces the life, can also cause serious accidents.Effective measures to prevent corrosion in buried pipeline cathodic protection technology is take.In the cathodic protection engineering, requirements of the protected pipeline and some device, which is connected with the equipment, branches off electrical connection, avoid the cathodic protection current loss to the connected components do not need protection.In order to ensure the success of the cathodic protection technology.

Referred to as the insulated joint with pipe insulation performance of the joint of buried steel pipeline requires the sealing performance, strength properties and electrical corrosion by the requirements of the.It contains a combination of parts, insulation board, filling, sealing ring, pipe etc..It is the replacement of insulating flange.

Structure characteristics

Insulating joint adopts integral extrusion welding, bolt, flange connection type shall be used.Insulating joint the insulation and sealing material inlaid and fixed on the sleeve (assembly) in the form of.After assembling, to the internal components shall be fixed on the relevant position.In the soil pressure, provisions of pipeline operation pressure and factory or field to test, the insulation joint is intact.Insulating joint sealing element on the joint is close to insulation board, with permanent elastic, and sealing elements directly mobile and bare metal surface contact not, to ensure that the tight joint.

Product features
