Flange Insulation Gasket Kit

Insulating sets are essentially used for pipeline flange corrosion protection, where a seal is required between dissimilar flange materials. The use of dissimilar metallic flanges with a conductive gasket material accompanied with a suitable electrolyte may set up a galvanic cell which will corrode the anodic metal. Insulating sets are also used to electrically isolate flange joints, preventing the flow of electrostatic charge along pipelines. AT PETROMET we manufacture the insulating gasket set consisting of one gasket; with one sleeve, two insulating washers and two steel washer for each bolt in line with ASME B16.5 flange.Types of Flange Insulating Gasket kitsThere are three standard Types of insulating sets available to suit raised face, flat face, and ring grooved flanges, as illustrated below.

 PETROMET FLANGE INC For Type F Raised Face Flanges :- In this type, the central gasket is designed to be located inside the flange bolt circle and sits fully on the raised face porting of the flange. This type of gaskets will be supplied in all the materials like Phenolic and Glass / Epoxy with Neoprene Rubber coating.

 PETROMET FLANGE INC For Type E For Full Face Flanges :-In this type, the central gasket has its outside diameter as equal to that of flange outside diameter and precision cut bolt holes. This design helps easy alignment of the gaskets during installation. Type E gaskets are available in Neoprene faced reinforced Phenolic / Glass Epoxy material or other materials in Table.

 PETROMET FLANGE INC For Type D For Ring Joint Gaskets :- In this type the gaskets are available in fabric reinforced Phenolic or Glass Epoxy. Available in basic Oval & Octagonal type. This type has the contact faces with oval shape. It provides a high reliability seal. These gaskets comply with ASME B16.20. Parts of Flange insulating gasket kits Insulating sleeves & washers Insulating sleeves manufactured of high density polyethylene, NEMA grade LE phenolic, and Mylar are available in a full range of sizes. Also available are one-piece integral sleeves and washers which are made of Minlon, providing superior compression strength. Integral sleeves are available in sizes through 1-1/2. A variety of high temperature sleeves are also stock items. With each insulating washer a 1/8 thick S.A.E. electro-plated steel washer is provided to protect the insulating washer from damage by the nut. Advance flange insulation sets are available in single or double washer kits. Flange protector Advance flange protectors and corrosion inhibitor grease are recommended on all insulated flanges. By encapsulating the flange cavity with the flange protector and injecting our corrosion inhibitor grease, you can rely on your cathodic protection system to provide you with years of trouble free service. This system totally eliminates any possibility of foreign material lodging between the faces of your flange or corrosion bridging across and creating a short.
