Pipe Flange Gaskets

A gasket is a sealing component installed between mating flange faces. When the connection is assembled and bolted, the gasket fills surface irregularities and helps prevent process fluids or gases from escaping through the joint. Pipe flange gaskets are selected according to the flange arrangement, service conditions, media compatibility, and required sealing performance.

The appropriate gasket for a raised face flange depends on the application and service conditions rather than the flange face alone. Spiral wound, soft-cut, and other compatible gasket designs may be suitable. Consider pressure, temperature, chemical exposure, flange dimensions, and material compatibility, then confirm the selection against the applicable project specifications before ordering.

Twinco Industrial supplies gasket options using non-asbestos, PTFE, graphite, mica, compressed fiber, EPDM, NBR, Neoprene, Silicone, and Natural Rubber. Spiral wound gaskets can include graphite, PTFE, or mica filler. Material selection should account for the operating environment, including chemical exposure, temperature, pressure, and the fluid being sealed.

Spiral wound gaskets are used to seal flanged connections in demanding industrial piping applications. Twinco’s options include graphite, PTFE, or mica filler configurations. They may be considered for oil and gas, petrochemical, power generation, and manufacturing systems where the gasket must accommodate challenging pressure, temperature, or chemical conditions.

Ring type joint gaskets, often called RTJ gaskets, are precision sealing rings used with compatible ring-type flange grooves. Twinco Industrial supplies RTJ gaskets in oval and octagonal cross-sections. The correct cross-section and dimensions must match the flange connection and project requirements to support proper installation and sealing performance.

Start with the flange type, face configuration, dimensions, and joint design. Then review operating pressure, temperature, chemical exposure, fluid compatibility, and the required gasket material or construction. Twinco supplies soft-cut, spiral wound, RTJ, metal-jacketed, rubber, and other non-metallic options, allowing selection to be aligned with the specific service conditions.
