Monolithic Insulating Joint .

It is an integral pipe fitting prefabricated and welded into a sealed whole in factory. An insulating ring together with sealing gaskets electrically isolates two sections of steel pipe, with an outer sleeve fully welded to form a non-detachable integrated structure. It guarantees smooth medium delivery and pressure tightness under working pressure while completely cutting off stray current to safeguard the pipeline cathodic protection system. Widely applied to buried steel pipelines for natural gas and crude oil. Compared with assembled insulating flanges, it features maintenance-free performance, superior pressure resistance and sealing property.
