The LS_SS style gasket is specifically designed for highly corrosive environments. It features a spiral wound construction with a conventional outer guide ring and a serrated inner ring, providing a dual sealing design that fully engages the raised face from the OD to the bore.
The LS_SS style gasket is specifically designed for highly corrosive environments. It features a spiral wound construction with a conventional outer guide ring and a serrated inner ring, providing a dual sealing design that fully engages the raised face from the OD to the bore.
The winding can be manufactured using the metal and soft filler specified by the user. The inner ring face is typically finished with 0.5 mm thickness Expanded PTFE or graphite.
The LS_SS gasket is widely approved for Hydrofluoric Acid (HF) service, though it has broader potential applications. Key advantages include: no direct metal contact with the media, excellent chemical resistance, fire-safe design, compliance with ASME B16.5 sizing, and availability in large diameters and for special flanges.
These gaskets are similar in construction to Style without inner & outer ring , with outer ring, with the addition of pass partitions designed for use in shell and tube heat exchangers. The partitions are typically supplied in double-jacketed construction, using the same material as the spiral wound component.
The LS_HT style gasket combines the corrosion and oxidation resistance of mica with the excellent sealability of flexible graphite. The mica, together with the metal spirals, acts as a protective barrier between the graphite and oxidizing process conditions or external air.
This gasket is engineered for use in Acid application. It utilizes a Monel and PTFE filler, combine with a carbon steel centering ring and a PTFE inner ring for added chemical resistance.
With widely usage, it is applicable to sealing under heavily alternating temperature or pressure such as the static sealing at flanges of pipeline, valves, pumps, heat exchangers, columns, manhole and hand hole. It has a wide application in petrochemical mechanical, electric power, metallurgical, ship-building, pharmaceu-tical, nuclear power and aerospace industries.
