Senja Insulation Gasket Kit
Description
SenjaInsulation Gasket Kit composed one piece insulating gasket, each bolt with one sleeve, each nut with one insulating washer and steel washer. Used in two different material pipeline flanges for anti-corrosion and prefects conduction of electricity.
Application
Special suitable for sea environment, hydrocarbon, chemical products and oil refinery pipeline.
Specification
1.The quad ring, a rectangular sealing element, encapsulated in special designed groove,it provide near zero “M” and “Y” factors to make the controlled-pressure seal can always be obtained without tremendous bolt loads.
2.The material such as Nitrile, EPDM, VITON and Telfon can be used as sealing elements, this increase the options for different working conditions.
3.Both retainer and sealing element’s temperature limit should be considered together while choose the material. Refer to chart for sealing gasket temperature range and material compatibilities.

Metal Washer of Material
Production of standard metal gasket material for galvanized steel gaskets, its size in the same way ast insulation gasket. we can also provide all kinds of stainless steel and special coatings.
Feature
1.Designed to withstand corrosive environments, including high concentrations of CO2 , H2S, produced water, etc
2.Outstanding insulation properties for cathodic protection
3.Gasket is sized to the bore to protect flange faces from media-induced corrosion and flow-induced erosion
4.Prevents turbulent flow at flanged connections
5.Mitigates galvanic corrosion in dissimilar metal flanges
6.Available to match any flange specification (ANSI,API,MSSP,BS,DIN,AS,others)
7.Easy installation, make up and removal
