Model NO.
HS Code
Product Description


The production as the picture shown above is made from carbon steel (outer ring material), high quality flexible graphite and stainless steel 304 (filler material), no inner ring.



Metallic Strip
The standard thickness of the metallic strip is 0.2 mm. 

Filler is normally used for thickness from 0.5 mm to 0.6 mm. 
- Flexible graphite 
- Ceramic

Centering ring
The centering ring does not come into direct contact with contained fluid. It is normally made of carbon steel and electro plated or painted to avoid corrosion. Other materials are available on request. 

Inner ring
Inner ring is used to avoid excessive compression due to high seating stress in high-pressure service and it is also used to reduce turbulence in the flange area. It is normally made of the same material as the gasket metallic srtip.

Manufacturing tolerances
The tolerance of the gasket diameters (d1, d2, d3, d4, s, s1) are stipulated by ASME B 16.20 and DIN 2632-2638 standards. The gaskets designed for non-standard flanges meet the recommendations by the ASME B 16.20.
