They are used as an insulator betweendissimilar metal flanges or to electrically isolate sectionsof pipework in cathodic protection systems, preventingthe flow of electrostatic charge along the pipelines.Kit ContentsNovus Sealing supply three standard types of FlangeInsulation Kits; designed to suit either raised face, flatfaced or ring grooved flange assemblies.Each kit comprises electrically insulating flangegasket plus the following components :One phenolic/mylar/GRE sleeve per boltTwo laminated phenolic/mylar/GREwashers per bolt

Thinner materials offer better temperature resistance than thicker grades.Pikotek PGE is a low pressure service gasket designed to give operators an alternative to phenolic based insulating gaskets.With the range of sealing elements provided the PGE is rated for most if not allHydrocarbon and water service applications.The unique offset design of the seal groovescreates a barrier, preventing any migrationof the fluid and or gas. The PGE gasketprovides a maintenance free, flange isolationand corrosion migration prevention solution.PhenolicNovus 34Uniflon 50Uniflon 51Uniflon 53Pikotek VCS has been designed to operate invery critical service applications. The gasketis suitable for use in Full Face, IBC and RTJflanges. It has universally acclaimed excellent dielectric properties and superior sealingcharacteristics. The gasket is suitable for allpressure ratings including API 15,000 psi.Pikotek is the registered trade mark ofour associate suppliers for PGE and VCSspecificationmaterials.Pikotek PGEPikotek VCS
Service RecommendationsThe choice of the insulation gasket isdependant on the application criteria. In addition to temperature, the pressure rating must be taken into consideration before selecting the gasket material.Seating StressSeating StressSeating Stress (20ºC)Gasket )Neoprene Faced Phenolic1530100To achieve an operationally reliable seal, theinsulating gasket should be assembled withinthe seating stress parameters shown here.Novus 3420*40*160*Uniflon 5015*40*135*Uniflon 5120*40*160**Note: For Neoprene faced phenolic gasketsthe bolts should be tightened using a torquewrench only. Hydraulic tensioning is notUniflon 5320*40*160*Pikotec PGE3050160Pikotec VCS3050400recommendedforthesegaskets.Experience has shown that a boltstress of 30,000psi must not be exceeded for Neoprene faced phenolic gaskets.* The seating stresses are dependent on the gasket thickness. Thinner materials offer a lowerminimum seating stress and a higher maximum seating stress than thicker materials.Flange Surface FinishIt is imperative that the flange faces are clean.The recommended surface finish of the flangesis 3.2um (125 RMS) to 6.3um Ra (250 RMS).Low Temperature ServiceInsulations sets which employ elastomericmaterials eg. Neoprene Faced Phenolicgaskets should not be used at temperaturesbelow -40ºC. For these temperatures werecommend the Uniflon range of gaskets orthe Pikotek range fitted with a PTFE seal.Contact our technical department forfurther information.How to order standard Neoprene Phenolic Insulation Kits Flange Insulation Type Size & Pressure rating or Ring Numbereg.
