Flange Insulation Gasket Kit Isolating Gasket Kits
We can supply full range of Flange Insulation Gasket Kits.
Type E Gasket, Type F Gaskets, Materials : Plain Phenolic, Neoprene, PTFE, G-7, G-10, G-11 etc.
Range of insulation gaskets kit including: CHG Higher Pressure Gaskets, CLG Low Pressure Gaskets, Insulation Sleeves, Washers.
Flange Insolation Kits are manufactured according to ANSI 16.5 specifications up to 24″, Above 24″, please provide the specifications of your flange using our convenient worksheet. Technical assistance is available upon request.
Insulation kits also called FLANGE ISOLATION KIT, are used to limit corrosion in pipeline systems. Where dissimilar metals are present, the sets remove the possibility of the system acting as a galvanic cell and reduce the risk of galvanic corrosion of the pipe work. Insulation sets are also used to isolate cathodically protected piping systems where they prevent the flow of electrostatic charge.
Each flange insulation set comprises one central flat or oval section gasket, plus one insulation sleeve, two insulating and two plated steel washers per bolt. The sets are individually packed and clearly labelled with the flange rating, size, type and material combination.
Flange insulation kits for cathodic protection are one of our specialties,Flange isolation kits have a proven track record for being one of the most effective and reliable products for controlling and maintaining the integrity of piping and tank systems under demanding conditions.
Flange Insulation kits can be used in the petrochemical, oil refinery, offshore seawater environments, where the transfer of volatile fluids through the pipeline can create explosive conditions which could be ignited by stray electrical currents.
Even where there is no risk of explosion these Insulation Kits are still used to act as a non-conductive interface between the two mating flanges to reduce the potential threat of galvanic corrosion of the pipework in cathodic protection systems.
Isolation gasket kits are designed to prevent leakage while protecting your system from corrosion caused by electricity. Several different styles are available to meet your specific requirements.
Isolation gasket kits Type E (Full Face Gaskets)
Isolation gasket kits 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 gasket are available in plain face or Nitrile faced phenolic, as well as variety of high temperture materials.
Standard thickness of 1/8″.
Isolation gasket kits Type F (Raised face Gaskets)
Type F Isolation gasket kits 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 Gaskets.
Standard thickness of 1/8″.
Type D (RTJ Flange Gaskets)
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 of ANSI specifications available in basic oval as well as octagonal shapes.
Also available are BX gaskets with pressure rating to 15,000 psi.
Metallic Core
The metallic core of gasket is made of stainless steel 316L.
Other metals, including Duplex and Inconel are available upon request.
