What is an insulating joint?
Insulation joints (or isolation couplings or isolation joints) provide electrical isolation and cathodic protection in pipelines, tanks and pump stations where oil, gas and water are the carrier fluids. Insulation fittings are available in sizes ranging from 2" to 48" and pressures ranging from ANSI 150 to ANSI 900.
Three features ensure electrical isolation.
The welded end hubs of our insulated joints are supplied according to the customer's pipe specifications. Optional extra-long stubs (supplied by the customer) can be included in the completed joint.
Features of insulating joints:
The primary advantage of an insulating joint is that it provides electrical isolation between two sections of pipe, which can help to prevent electrical accidents and protect personnel.
Insulating joints are commonly used in a variety of applications, including:
Changhao's insulatingjoints feature a prefabricated, non-separable and boltless design to meet the needs of customers who require a single-piece construction to simplify installation, eliminate maintenance and allow for easy final wrapping and coating of the pipe after installation. The design is tested for pressure fatigue, torsion and bending to provide a design that is physically stronger than the pipe it is attached to.
