Monolithic Insulating Joint
The monobloc insulating joint is a general name for the joint which can substitute insulation flange and has both the sealing performance required by buried steel pipe and the electrical insulation performance required by electrical corrosion protection engineering. The utility model comprises a pair of internal and external connecting parts, and an insulating seal coat in the middle of the connecting part and a pair of steel short pipes welded with the connecting part respectively. It is an important component for cathodic protection of pipeline in pipeline transportation in order to prevent electrochemical corrosion. It has higher stiffness than insulation flange, can bear large bending moment, high insulation performance, long life, and can be buried in the installation.
