Abstract: A system for applying a web around a cylindrical object with even tension containing a core having a generally cylindrical shape and a pair of handles. Each handle has an insertion area, a collar area, and a gripping area. The collar area is sandwiched between the insertion area and the gripping area and the insertion diameter is less than the inner diameter of the core at the first end and second end. The handles and core have a means for coupling meaning that the core and the insertion area of the handles do not move independently from one another.

Abstract: A method and apparatus for repairing polyolefin structures such as polyethylene piping. The repair method involves a bi-material co-extruded film that homogenously attaches to the poly olefin pipe surface and enables bonding of either epoxy or polyurethane composite material to the overall structure. The method involves surface cleaning with a solvent, attaching the co-extruded film, and applying a heat-activated shrink tape. The surface is heated to activate the bonding process of the film to the PE surface and to create a compressive force via the shrink tape. Once accomplished, the shrink tape may be removed and either a fiber reinforced polyurethane system or a fiber-reinforced epoxy system is applied and allowed to cure.
