What is an insulating flange?
An insulating flange can also be referred to as flange insulation kid or flange isolation kid(FIK). Insulating flanges are those flanges equipped with plastic parts that insulate and prevent the flow of current between two metal surfaces.Insulating flanges are used in cathodic protection systems to prevent electrolytic corrosion.
The insulating flange has simple structure,safe operation and reliable performance.It is produced for petroleum, chemical and other industries.Insulated flanges include a pair of steel flanges, an insulating seal between the two flanges, flange fasteners and insulating parts of fasteners, and a pair of steel studs welded to each of the two flanges.
Insulating flange is a general designation of the flange joint of the pipeline which has both the sealing performance required by the buried steel pipeline and the electrical insulation performance required by the electrochemical corrosion protection project.
Insulating flange products have formed a series. In case of special circumstances, they can be designed and manufactured according to the user’s requirements. According to the different insulation seals, the insulation flange can be divided into two types: pressure seal type insulation flange (I-type insulation flange for short) and self tightening seal type insulation flange. Insulating flange is mainly used between gas transmission and distribution pipeline and gas pressure regulating, metering, storage and other equipment. Its main function is to insulate and isolate each section, equipment and pipeline of gas transmission and distribution pipeline, protect them from chemical corrosion, and extend the service life of pipeline and equipment. The product conforms to SY / t0516-1997 technical code for design of insulated flange.
This product is divided into specific pressure seal type insulating flange and self tightening seal type insulating flange according to the different insulation seals.Haihao Group as a professional pipeline supplier,we supply insulating flanges in different dimensions,standards,materials.If you want to know more about our piping products,please email to us:firstname.lastname@example.org
