Easy To Handle And Fit Blow-out Resistant Spiral Wound Metallic Gasket

Spiral wound gasket is formed of V-shaped of W-shape stainless steel stripe and soft nonmetallic packing or the material of flexible graphite asbestos, nonasbestos, PTFE etc by means of piled. It can use inner ring and outer ring as different material such as carbon steel, stainless steel 304, 316, 316L and etc. The static sealing element of pipe, valve, pump, thermal exchange, condensing motorcycle, auto vent-pipe, tower, plain hole and hole of flange, etc.


TFG CGI Type Spiral Wound Gasket:

SWG with inner and outer ring, for raised & flat face flange.

For example: SS316L/SS316L+FG/SS316L

Standard:ASMEB 16.20,DIN,GB

Metal - jacketed gaskets are particularly suitable for sealing flat surfaces of heat exchangers, gas pipes, cast iron flanges, autoclaves and similar. By their sealing efficiency, provided by exerting strong pressure on circular rims of the flanges, metal - jacketed gaskets can stand up to 30% deviation from the initial thickness, which is very useful in case of irregular or faulty flange rims. The chemical compatibility of the metal and the medium being sealed should be considered.


ADVANTAGES
Suitable for high assembly stress.
Highly resistant against blow-out.

SHAPE AND CONSTRUCTION
Metal-jacketed gaskets are produced in several types to meet the requirements of the most demanding applications. Inside a metallic jacket they feature a soft filler as shown in the figure.

Kammprofile is a composite gasket, which utilises a serrated metal core with a soft facing material.
The metal core is a machined on each contact face with concentric serrations which provide high pressure areas, ensuring that the soft coating flows into any imperfections in the flange even at relatively low bolt loads. The result is a gasket, which combines the benefits of soft, cut materials with the advantages of seal integrity associated with metallic gaskets. Expanded graphite is the most common facing material used for Maxiprofile gaskets. However, other materials can be used, such as PTFE for chemically aggressive duties or mica for high temperature duties.


General Properties of Kammprofile Gaskets:
1. Have a wide range of seating stresses under which the seal is effected and maintained
2. Can be used when there is insufficient bolt load to seal conventional gasket materials
3. Easy to handle and fit
4. Suitable for a wide range of operating conditions
5. The soft facing layer prevents damage to the flange
6. Provide a high integrity seal including thermo cycling and shock loading conditions
7. Sealing is not sensitive to uneven bolt loading conditions
8. Can be refurbished with a new facing layer and reused


Applications of Kammprofile Gaskets:
1. Heat Exchanger and Vessel applications
2. High and low temperatures
3. Pressures of up to 250 bar
4. Low bolt loads
5. Small flange widths
6. Damaged flanges
