Flange and Bolt Insulation

Industrial Gaskets manufactures and stocks an extensive range Flange and Bolt Insolation products

Flanges, the most common trouble area, need to be sealed properly to prevent leakage and must also be cathodically insulated to prevent stray currents which cause undo corrosion and eventual breakdown of the metal.

A flange is typically insulated for cathodic protection reasons. Insulating the flange requires that no metal to metal contact occurs between the two flanges, this includes between the bolts. Insulating sleeves and washers are used on the bolts that prevents this contact.

Isolating products are used to guarantee the safe flow of fluids passing through pipeline transmission, distribution and process piping systems.

Flange and Bolt Insulation products are the most widely used form of controlling losses due to corrosion. They can be used to control stray electric currents in piping at oil, gas, water, refinery, and chemical plants, to increase the effectiveness of cathodic protection systems and confine or eliminate electrolytic corrosion.

Industrial Gaskets can supply various sizes and types of insulating gaskets and complete gasket kits to suit any pressure or product requirements They are available in variety of materials. Each kit is supplied either with steel and insulating washers, sleeves and a insulating gasket or TopHat bolt insulators, steel washers and an insulating gasket.

The most common insulating materials include Minlon©, G11 Glass Epoxy, G10 Glass Epoxy, Mylar, Phenolic, PTFE (or Teflon©). At Industrial Gaskets they are available for all flange sizes, types, pressure ratings.

Flange Insulation is designed to combat the effects of corrosion often found in flanged pipe system. Galvanic corrosion between dissimilar metal flanges, flange insulation associated with cathodic protection of underground piping are other examples where Flange Insulation can be put to effective use.

Industrial Gaskets manufactures Flange Insulation Kits in Type E, Type F and Type D configuration, TopHat Bolt Insulators, Insulating Washers and Insulating Gaskets.

Industrial Gaskets is the Australian agent for Advance Products & Systems LLC in USA for their severe service flange, bolt isolation and protection products.
