For enhanced protection, the carbon steel outer ring can optionally be coated with a special acid-detecting paint. The PTFE inner ring helps minimize flange corrosion by protecting the area between the pipe bore and the inner diameter of the spiral wound sealing element
The LS_RF style gasket shares the same construction features as a standard gasket but is specifically sized to serve as a replacement for flanges machined to accept oval or octagonal ring joint gaskets. The sealing element is positioned between the groove ID in the flange and the flange 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.
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.
Inward buckling of spiral wound gaskets remains a concern in the industry. Various industry committees are actively working to improve standards to address this issue. Some end users avoid using inner rings due to cost or bore intrusion. To meet this need, We offer LS_AB style gasket.
