Insulating flange assemblies are a general term for pipeline flange joints that meet the sealing requirements for buried steel pipelines and the electrical insulation performance required for anticorrosive engineering. They include a pair of steel flanges, an insulating seal between the flanges, flange fasteners, insulating components for the fasteners, and a pair of steel short pipes that have been separately welded to each flange. Insulating flange assemblies and insulating joints are products produced for industries such as oil and chemical engineering, characterized by simple structure, safe use, reliable performance, and have received widespread positive feedback from customers.

Insulating flange components have been developed into a series. In case of special circumstances, they can be custom-designed and manufactured according to customer requirements. The insulating flange components are primarily used in gas transmission and distribution pipelines, as well as in equipment for gas regulation, measurement, and storage. Their main function is to provide insulation and isolation between sections of gas transmission and distribution pipelines, and between equipment and pipelines, thereby protecting them from chemical corrosion and extending the service life of both pipelines and equipment. The products comply with the standard SY/T0516-1997 "Technical Specification for Design of Insulating Flange Components."
