Flange isolation gasket kits-Type D, E, F,O

Flange isolation gasket kits are designed to maintain the integrity and reliability of the pipeline and piping system through safety and corrosion protection.Flange isolation gasket kits provide an effective seal and electrical isolation of flanges. By eliminating metal to metal to metal contact, static current is halted to prevent corrosion and aid in the cathodic protection of the pipe.There are four types of flange isolation gasket kits,the details are as follows:

Flange insulation gasket type D finished in Haihao Group

Type D Gasket Kit:

Type D gaskets are specifically designed to fit into the ring groove of ring-type-joint flanges. They are manufactured of a medium weave, fabric-reinforced phenolic material and are sized to ANSI specifications available in basic oval as well as octagonal shape. Also available are BX gaskets with pressure ratings to 15,000 PSI.

Type E Gasket Kit:

Type E is a full-faced gasket with the same outside diameter as the flange and precision cut bolt holes.This design facilitates proper alignment of the gasket during installation and foreign material prevented from shorting the flange isolation. Type E gaskets are available in plain face or Nitrile faced phenolic, as well as a variety of high temperature materials. Standard thickness of 1/8″.

Flange insulation gasket type F finished in Haihao Group

Type F Gasket Kit:

Type F gaskets are made to fit the raised face portion of the flange only.As there are no bolt holes in the F gasket,the inside diameter of the bolt hole circle is slightly smaller than the outside diameter of the gasket,assuring an exact, automatic positioning of the gasket.Type F gaskets are available in the same materials as the type E gasket.Standard thickness of 1/8″.

Type O Gasket Kit:

Gasket and O-Ring are available in different materials to maintain constant contact with the flange face.The O-ring allows near zero leakage static sealing and limits the area of seal exposed to fluid attack.Type O Gaskets have a sealing element on each side of the gasket and are available in both Type E and Type F styles.The sealing element materials are Nitrile,Viton, or Teflon.Type O gaskets are made of both phenolic and G-10 materials.
