Abstract
A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant filaments on one surface of the backing, and pressure-sensitive adhesive layer that coats the filaments and binds them to the backing.
Claims4
A method for constructing a member for undersea deployment is provided, which comprises:
- winding a wire reinforcement about tubular member(s);
- and
- winding a seawater-resistant reinforced tape over the wire reinforcement, wherein the seawater-resistant reinforced tape comprises:
- a polymeric film backing;
- a layer of corrosion-resistant fiber directly adjacent one surface of the polymeric film backing;
- a first pressure sensitive adhesive layer bonding the corrosion-resistant fiber directly to the polymeric film backing;
- and
- a second pressure sensitive adhesive layer directly adjacent the first pressure sensitive adhesive layer;
- wherein the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer comprise the same adhesive
- wherein the corrosion-resistant fiber comprises glass, aramid, ultrahigh molecular weight (UHMW) polyethylene, polypropylene, carbon filament, or combinations thereof.
