A gasket is a mechanical seal which fills the space between two mating surfaces, generally to prevent leakage from or into the joint objects while under compression.
The gasket material which is required to produce a tight seal is dependent upon the roughness of the surface. The gasket must be able to maintain this seal under all the operating conditions of the system including extreme upsets of temperature and pressure. Therefore, it is important to ensure proper design and selection of the gaskets to prevent flange-leakage problems and avoid costly shutdowns of the process plants.
We have more than 10 years experience in making different kinds of gasket. The scope of our supply with regard to sealing meterial is as follows: ·Spiral Wound Gaskets, both standard and special dimensions in all available materials. ·Ring joint gasket ·Gland (braided) fiber packing ·Gasket Sheet ·Flat gaskets both standard and special dimensions in all available material types, including gasket sheet and solid metal. ·Laminated gaskets (MRG, Kammprofile) ·Metal clad gaskets. ·Machined metal gaskets such as API Ring Joint Gaskets etc. ·Tape and cord sealing
