Product Description

FLANGE ISOLATING GASKET KITS are designed to work in conjunction with our isolating gaskets to effect the complete electrical isolation of a flanged assembly. The Isolation Kits consist of one full-length isolating sleeve, two isolating washers and two steel washers for each of the bolts in the flange assembly. The purpose of the isolating sleeves is to electrically separate the bolts from each side of the flange, while the isolating washers provide electrical isolation for each of the nuts attached to the bolts. This method of isolation provides the user with a high-reliability solution to complete the electrical isolation of a flanged joint.

Product Detail

FLANGE ISOLATING GASKET KITS

Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically isolated to prevent stray currents which cause undo corrosion and eventual breakdown of the metal. Advance Products & Systems manufactures and maintains a supply of quality products and materials which help solve most flange sealing problems, therefore preventing subsequent corrosion and saving the integrity of the pipeline.

Advance Flange Isolation Gasket Kits are manufactured according to ANSI B16.5 specifications up to 24". Above 24", please provide the specifications of your flange using our convenient worksheet. Technical assistance is available upon request.

TYPE D
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
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".

TYPE F
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".

ISOLATING SLEEVES AND WASHERS
Isolating sleeves manufactured in various materials, as well as sizes, are available to meet every customer’s needs. 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 isolating washer, an S.A.E. electroplated steel washer is provided to protect the isolating washer from damage by the nut. Advance flange isolation sets are available in single or double washer kits.
