WEKO-SEAL can be for trenchelss rehabilitation of a variety of pipeline configurations and materials

Water

Seals designed for use in potable water applications are made from EPDM (Ethylene Propylene Diene Monomer) rubber seal and type 304 stainless steel retaining bands. All components used for potable water applications are NSF 61 drinking water approved classified by Underwriter’s Laboratories. Storm water installations use the exact material components as identified for potable applications.

Wastewater

Wastewater applications use the EPDM (Ethylene Propylene Diene Monomer) rubber seal and type 316/316L stainless steel retaining bands.

Natural Gas

Seals designed for natural gas applications are constructed of Nitrile (butadiene acrylonitrile) rubber. This material provides superior resistance to gas, oil, petroleum, alcohol, impact and electricity. The seal retaining bands are constructed from 1018 carbon steel.

Seawater/Brackish Water

Installations in salt water environments consist of an EPDM (Ethylene Propylene Diene Monomer) rubber seal and AL6XN retaining bands. Made from this exotic super stainless steel, they exhibit superior long-tem resistance.
