Kaxite Type F flange insulation kits are the standard raised-face isolation solution for RF flanged joints. The gasket covers only the raised face area inside the bolt circle — the minimum insulation geometry that still provides complete electrical isolation and full seal performance across the joint. Each kit is supplied as a complete pre-packed set: insulating gasket, insulating sleeves and insulating washers, matched to the flange bolt pattern and labelled with flange size and pressure rating. Materials include reinforced phenolic (standard), Minlon (high toughness) and Mylar (thin section). Kits are available for ASME B16.5, ASME B16.47, API 6A and DIN/EN flanges, Class 150 through Class 2500. Standard sizes ship in 7–15 days, custom sizes in 15–30 days.
Kaxite Type E flange insulation kits are full-face isolation kits for raised-face and flat-face flanged joints. The gasket has the same outside diameter as the flange, with precision-located bolt holes — so the entire mating surface is protected from contact corrosion and the gasket self-centres on the flange inside diameter without a separate centring ring. Each kit is supplied complete: full face insulating gasket, insulating sleeves and insulating washers, pre-packed to match the flange bolt pattern. After installation, the exposed flange edge can be taped to prevent foreign material bridging the isolation gap — the standard anti-shorting measure on buried and outdoor lines. Materials include reinforced phenolic, Minlon and Mylar. Kits are available for ASME B16.5, ASME B16.47, API 6A and DIN/EN flanges, Class 150 through Class 2500.
Kaxite Type D flange insulation kits are engineered for RTJ (ring joint) flanges — the gasket is profiled to sit inside the ring groove rather than on a raised face. Each kit is supplied as a complete isolation set: insulating gasket, insulating sleeves and insulating washers, pre-packed to match the flange bolt pattern and labelled with flange size and rating. The kit breaks electrical continuity between two mating flanges to prevent galvanic corrosion between dissimilar metals and to isolate the joint from cathodic protection currents on buried or submerged pipelines. Materials include reinforced phenolic, Minlon and Mylar. Kits are available for all common flange standards (ASME B16.5, ASME B16.47, API 6A, DIN/EN) across Class 150 to Class 2500.
