Internal Floating Roof Wiper Seal Systems
MesaWedge primary and secondary seal systems are designed to prevent product loss and atmospheric contamination from Internal Floating Roof Tanks (IFRT). MesaWedge seal systems meet or exceed environmental regulations and are designed to ensure effective operation in specific tank conditions. Mesa ETP manufactures multiple options of IFRT wiper seals, talk to one of our tank experts to learn more MesaWedge and which option would be the best fit for your tank.
MesaWedge SC-1000 is a 65A Duro urethane featuring exceptional abrasion resistance that is unmatched in the industry. It also offers flexibility and chemical resistance to meet the needs of storage applications. SC-1000 may be used as a primary seal system (Single MesaWedge) or combination primary and secondary seal system (Double MesaWedge). SC-1000 is available in a range of widths to accommodate the rim seal space of the tank’s internal floating roof. Factory splicing or field splicing kits are available as well as instructions. Pre-radiused sections are available for tanks under 40 ft in diameter.
MesaWedge SC-1200 is a closed cell foam nitrile/vinyl copolymer designed for an Internal Floating Roof Tank (IFRT) seal. SC-1200 is especially suited for lightweight internal floating roofs of varying sizes. SC-1200 is compatible with 100% pure alcohols, M.T.B.E. and 70% aromatics; excellent hydrolytic stability ensures minimal chemical decomposition (hydrolysis) in water. SC-1200 offers high tensile strength and abrasion resistance while maintaining a lightweight and flexible design. SC-1200 may be used as a primary seal system (Single MesaWedge) or combination primary and secondary seal system (Double MesaWedge). MesaWedge SC-1200 offers vapor tight splicing options that maintain the integrity of the seal around the tank diameter
