Gaskets 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 imperfections on the flange to create initial seal on application of sealing force.The 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 free jointing sheets are manufactured on latest
factory 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 engineers with
experience of a life time. Our products meet with the increasingly
exacting requirements in engineering and chemical industries for
contact gaskets on fixed sealing faces. Spitmaan Asbestos free jointing
sheets are manufactured to international quality standards, which our
customers can depend upon. The operating temperature for asbestos free
jointing sheet 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 seal ability that the flanges are clean and free from any serious defect.
