Filament reinforced tapes useful as underwater pipe wrap
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.
1. 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.
2. The method of claim 1 , wherein the first pressure sensitive adhesive and the second pressure sensitive adhesive is selected from acrylic, silicone, synthetic rubber, natural rubber and modified acrylic formulations.
3. The method of claim 1 , wherein the tubular member(s) is/are conduit(s).
4. The method of claim 1 , wherein the corrosion-resistant fiber comprises polymer-coated E-CR glass, polymer-coated AR glass, polymer-coated S glass, polymer-coated E glass, and combinations thereof.
