Flange Insulation Gasket Kits are a flange joint package, including gaskets, sleeves, and gaskets. Each flange group is safely packed in a cardboard box, clearly marked with size, ASA grade, style, and material. These insulation kits are available with polyethylene or phenolic bushings. Polyethylene sleeve is standard and will be provided unless otherwise stated.

　　Type D

　　(API ring joint)-Gasket is an insulating ring joint gasket, used to match the ring groove of the ring joint flange. The D-type central washer is made of medium woven fabric reinforced phenolic resin, manufactured in accordance with ASA (ANSI) washer dimensions. The performance is similar to that of the phenolic flat central gasket, which can provide a basic octagonal shape. The oval shape can be ordered according to special requirements. When installing D-type gaskets, it is also recommended to wrap the tape around the outside of the flange to prevent foreign matter from trapping between the exposed parts and causing the flange to "short circuit". When installing all flange Insulation Gasket Kits, use positioning pins as much as possible to ensure that the flanges are properly aligned. The pin should be at least 3/32" (2.38mm) larger than the bolt size.

　　(Full Face)-The gasket is designed to fully protect the flange and has the same outer diameter as the flange. Each washer has precisely positioned bolt holes. During installation, it is recommended to wrap the tape around the outside of the flange to prevent foreign matter from trapping between the exposed parts and causing the flange to "short circuit". All E-type gaskets can be easily aligned with the inner diameter of the flange. Washers with a slightly larger outer diameter are available on request.

　　F type

　　(Ring)-The gasket is designed to mount the convex part of the flange. The outer diameter of the gasket is slightly smaller than the inner diameter of the bolt hole circle. The outer diameter is designed for alignment by insulating sleeves. The material of the central washer is the same as the E type. During installation, it is recommended to wrap the tape around the outside of the flange to prevent foreign matter from trapping between the exposed parts and causing the flange to "short circuit".
