METHOD OF APPLYING RUBBER LINING TO THE INTERNAL SURFACE OF PIPING AND FITTINGS

A method of lining a piping assembly with rubber to form a rubber liner. An inner surface of the piping assembly is selected for lining. One or more containment devices are attached/inserted in the piping based on the selected surfaces. The inflatable bladder is introduced to an inner bore of the piping. The inflatable bladder is inflated to a predetermined pressure. An oven or autoclave is heated to a predetermined temperature. The piping assembly is introduced to the oven and heated until a predetermined curing temperature. The piping assembly is cooled for a predetermined cooling time and a rubber inner liner is formed on the selected surface.
