Asbestos braided oil seal gaskets are used for sealing the oil seal chambers of valves, centrifugal and piston pumps, as well as various aggregates at operating temperatures from -70 to +300C.
Braided stuffing boxes are the most common type of sealing materials used to fill the stuffing boxes of valves, centrifugal and piston pumps, and various devices. More than 70% of pumps and 80% of fittings are equipped with these gaskets. They differ both in the materials from which they are made, and in the manufacturing methods (structure). Both of these factors significantly affect the performance properties of gaskets.
The basis of braided gaskets are various fibrous materials. In the ATI sub-industry, threads and yarns made of asbestos, cotton, bast and chemical fibers are used for making woven stuffs.
An important component of gaskets are various types of impregnation and fillers that give them the necessary properties.
