Size And Construction
The non-metallic gaskets are produced in several sizes and shapes to meet the most demanding applications. They are available in standard and non-standard gasket design. For non-standard gasket we can provide any shape and size according to customer design or sample.
Advantages
- Wide temperature use range: -200°C + 250°C
- Very low coefficient of friction
- Anti-stick properties
- Non-flammable
- Excellent dielectric properties
- Good mechanical properties
- Excellent tensile strength even at low temperature
- Non-ageing properties
- Moisture and U.V. resistance
- Non-toxic
- Resistance to all corrosive chemicals.
The dimensions of our standard gaskets meet the requirements of the AWWA STD or other standards. Gaskets of up to 2000 mm x 2000 mm are made from one piece, while larger ones are assembled from segments. Two kinds of splicing are used: dove-tail and bevelled (practically there are no limitation regarding gasket dimension). According to the gasket shapes and sizes all other dimensions can be manufactured upon request.
PTFE is the material choice for a very large variety of applications, The chemical inertness of PTFE is unique makes it suitable for almost all chemicals with the exception of fluorine, some flour chemicals and molten alkali metals,
Metalic Flat Flange gaskets
Non-Asbestos flat flange gaskets are the most typical static gaskets. They are used in large number by various industries and in a variety of applications, especially when low and medium sealing conditions are applied. Non-Asbestos gaskets are made of compressed fibre sheets, graphite, PTFE, mica or rubber sealing materials. Flat-flange gaskets are produced in several different sizes according to standard or customer design. Special type of non-metallic flat flange gaskets are metal eyeleted gaskets, which provide special protection against blowout for the sealing of critical of agressive media. The core of the gasket is usually made of CSF or expanded graphite material, while the U-shaped eyelet is made from different metals.
Application
- Water Systems
- Gas and oil installation
- Food industry
- Chemical industry
- Petrochemical industry
- Shipyard industry
- Automotive industry
PTFE Eveloped Gaskets
Properties and Characteristics
An insertion is made from a soft material, corrugated stainless steel or rubber and then enveloped with virgin PTFE. PTFE enveloped gaskets are used for flange joints where extreme chemical resistance is required. These gaskets have good pressure stability under different applications.
Gaskets Profile
PTFE eveloped gaskets are produced in several different profiles. Virgin PTFE is used for eveloped materials. Stainless steel, CSF or rubber are used as core material.
General Characteristics
- Good chemical resistance to different media withstand temperature
- Temperature resistance upto 26o0C
- Low friction coefficient
- Non-adhesive surface
- Very good electrical insulation and low thermal conductivity.
