The Riser-Wrap seal is a two-layer system designed for corrosion and sealing protection on encapsulating manholes and pipelines to seal joints against ground water infiltra-tion, tolerant to soil stress, UV and freeze-thaw conditions. The first layer is a rugged sealant encapsulated by a heat shrink sleeve. A 2.5-mm cross-linked, high density polyethylene membrane. Applications are for manholes (pre-cast base, cone, risers, cast iron frame), concrete vaults boxes, septic tank joints, repair and step-down joints. Designed for rehab and new construction.
In highly sensitive areas, where operators can’t afford a leak, the LineSeal gasket seals fl anges containing high pressure or extremely dangerous product. Pipeline Seal & Insulator, Inc. announces an alternative for extreme critical sealing applications: the new LineSeal sealing and fl ange isolation gasket. PSI has developed the LineSeal gasket to perform at a higher level than what is currently being used in the environment. The 316 stainless steel cored gasket features G-10 retainer material and a PTFE (Tefl on) seal as a standard. It seals all pressure ratings through ANSI 2500 class and API 15,000 psi service, while withstanding CO2 or H2S. Proven in service overseas, the LineSeal gasket has recently been tested to the detailed and rugged Shell testing standard. It is available as a standalone gasket or as part of a high-quality PSI fl ange isolation kit. All PSI sealing gasket products are manufactured to ISO 9001:2000 standards and are available in Edmonton, Alberta, by GasketMaster.
