Korea Fuji metal jacketed gaskets are fabricated with Non-Metallic for inner filler as metallic of outer shell.
They are widely used in heat exchangers, Boilers, Pumps, valves with high temperature and severe corrosion conditions for various plants. (Powers, Chemicals, Oil Refineries, Iron plants) Metal jacketed gaskets fabricate by hand-made to various shapes and sizes as Round, Oval, Oblong in order to supplying. Besides, many materials are able to use according to temperature, pressure and corrosive conditions. (Please refer to page 78/80 for jacket and filler material) Recently for sealing improvement Graphite and PTFE tape glued together on both sides of gasket in view of increasing consumption. Effective is especially high in case of damage caused by corrosion on flange surface.
Single Jacketed Gaskets
Gaskets are jacketed with one thin metal to inner filler.
his sort of gasket is used in Boiler, compressor, Pump, Diesel and Gasoline Engines of low pressure, however not recommended for standard pipe flange, minimum flange width 6.4mm, nominal gasket thickness 3.2mm Also available are round jacketed gaskets applicable to Boiler Man-hone, Steam trap and Sight Glass.
Double Jacketed Gaskets
The filler material is completely enclosed by a two piece metal jacket, which covers both the inside and outside diameters and both contact surfaces KFP 471 is similar to style KFP 470 with the exception that the metal jacket is formed from a corrugated jacket providing better resilience than the KFP 470, since the corrugations form multi-seals across the flange sealing face.
Double Shell Type Jacketed Gaskets
KFP 474 is a double shell type jacketed gasket constructed of two reversed wrap-round shells. This provides superior flange support and handleability and provides better resistance to high pressures.
Double jacketed gaskets are used on Boiler and Heat Exchanger applications when ample bolting is available to correctly seat the gasket. They are designed for high pressure and temperature applications up to and inclusive of class 900. The temperature limitation of the gasket is dictated by the combination of metallic and non-metallic materials used in its construction.
Flange widths as narrow as 8mm(5/16 )can be manufactured, dependent on diameter. Very large gasket diameters can also be produced. Nominal gasket thickness 3.2mm(1/8 ).
Gaskets can be manufactured with either integral or welded pass partition bars, in a variety of complex configurations. Some of the most common pass bar configurations are shown on page 34
Solid Corrugated Metal Gaskets
As the name suggests, the solid corrugated metal gasket is comprised solely of metal and does not contain any non-metallic fillers in its construction.
The temperature limitation of the gasket is therefore only effected by the metal selected.
The corrugations provide multi-seals across the face of the gasket and inherent resilience.
A minimum of three corrugations is recommended and gasket thickness is approximately 50% of the corrugation pitch.
Typically used for high temperature applications and applications involving steam, water, gas, oil etc. up to
