Cut Gaskets

Cut Gasket as per size & drawing of Asbestos / Non-Asbestos Jointing & PTFE Gasket. Gasket must maintain a seal for an acceptable period against all of the operational forces involved and to achieve this, there are eight important properties which any good gasket should possess:

• The Gasket should not be porous to the fluid being sealed.
• The gasket should compress into the inperfections on the flange to create initial seal on application of sealing force.
• Gasket should not show significant creep under the influence of load and temperature. Such flow will allow the bolts to relax, reduce gasket surface stress and cause leakage.
• The gasket should be capable of catering to slight distortion between the flanges.
• The gasket should withstand chemical attack from the media being handled.
• The gasket has to be easily dismantled after use.
• The gasket should be able to withstand effects of temperature of the confined media.
• The gasket should not cause corrosion of the flange faces.

Spitmaan Asbestos Fibre Jointing Sheets & Non-Asbestos Jointing Sheets are manufactured on latest equipments and developed with the aid of research and scientific facts to take care of one and all of above factors combined with highly specialised technical knowledge of Engineering and chemical industries for contact gaskets on fixed sealing faces. Spitmaan Asbestos Fibre Jointing Sheets & Non-Asbestos Jointing Sheets are manufactured to international quality standards, which our customer can depend upon. The operating temperature for Asbestos Jointing Sheets & Non-Asbestos Jointing Sheets material is related to the thickness selected. Thinner materials offer better temperature and pressure properties.

Proper Bolting Procedure
The sequence in which bolts are tightened has a substantial bearing upon the distribution of contact area stress. Improper bolting may cock the flange out of parallel. It is important for proper sealability that the flanges are clean and free from any serious defect.
