Patent number: 10724660Abstract: A flexible pipe includes: an inner liner formed as a tube and having an outer surface and an inner surface defining an inner diameter; a reinforcement layer bonded to the inner liner and including at least a first ply of reinforcing tape helically wrapped in a first helical direction about the inner liner and a second ply of reinforcing tape helically wrapped about the first ply of reinforcing tape, the second ply of reinforcing tape helically wrapped in a second helical direction opposite to the first helical direction; and an outer jacket applied over and bonded to the reinforcement layer, the outer jacket including a thermoplastic. A reinforcing tape for use in the pipe or other applications includes: a plurality of reinforcing fibers and a matrix about the plurality of reinforcing fibers to hold the reinforcing fibers in the form of a tape, the matrix including thermoplastic and an additive to increase the impact resistance of the thermoplastic.Type: GrantFiled: June 29, 2017Date of Patent: July 28, 2020Assignee: SHAWCOR LTD.

Publication number: 20190217337Abstract: The present invention relates to coating compositions, processes for making them, and methods of application of the coating compositions. Further, the present invention relates to a process and apparatus for coating a metal substrate, for example an elongated metal tubular substrate such as a pipe. Most particularly, the coating can be used as an anti-corrosion coating on a pipe for use in oil, gas and water pipeline applications.Type: ApplicationFiled: May 12, 2017Publication date: July 18, 2019Applicant: SHAWCOR LTD.Inventors: Nitin Gujare, Jiri Holub, Jun Tabiendo, Alfredo Andrenacci

Publication number: 20040028862Abstract: A fibrous closure comprises a dimensionally stable, heat resistant fibrous backing layer and a layer of high shear strength pressure sensitive adhesive. The closure is used in conjunction with a heat shrinkable, wraparound sleeve for sealing cable jackets, connectors and joints between lengths of pipe or other elongate objects. The sleeve is wrapped around the object such that its ends overlap. The closure is then applied over the overlapping ends of the sleeve to prevent slippage of the overlapping ends during heat shrinking, and to prevent subsequent creeping of the overlap joint due to hoop stresses in the shrunken sleeve. The closure avoids use of a relatively inflexible polymeric backing layer, and is therefore able to conform to objects having a relatively small diameter or irregular shape.Type: ApplicationFiled: August 12, 2002Publication date: February 12, 2004Inventors: Douglas Neil Burwell, Alfredo Andrenacci, William Peter Buckley

Patent number: 5786053Abstract: An article, for example a pipe, has a first covering such as a polymer layer, and a second covering, such as a repair patch or a repair deposit of melt-on adhesive or a wrap or a sleeve protecting a welded joint between two lengths of such pipe. The second covering may have a functional coating on an underside which is applied on and is at least partially superimposed over the first covering. A cured deposit of thermoset resin is applied at least over the edges of the second covering, for example in the form of a fibrous tape impregnated with a curable resin composition, and bonds to the first and second coverings. The resin deposit provides the second covering with increased stability against displacement laterally of said first covering, for example as a result of soil stress.Type: GrantFiled: January 28, 1997Date of Patent: July 28, 1998Assignee: Shaw Industries, Ltd.Inventors: Alfredo Andrenacci, Michael A. Romano, John H. Oliver

Patent number: 5720834Abstract: A pipeline is covered with a continuous wrapping sheet having heat-activatable adhesive on its inner side. The wrapping may be helically applied or may be heat shrunk to impart a circumferential stress conforming the wrapping tightly to the surface of the pipe. High frequency induction heating is applied to cause the adhesive to wet and bond to the pipe surface. The wrapping can be applied progressively and continuously along a pipeline excavated from the ground while the pipeline is in service. The product conveyed within the pipe assists in rapidly cooling the adhesive and wrapping sheet so that the pipe can be promptly relaid in the ground.Type: GrantFiled: May 4, 1992Date of Patent: February 24, 1998Assignee: Shaw Industries Ltd.Inventors: Robert Edward Steele, Michael A. Romano, Donald C. Warren, Alfredo Andrenacci

Patent number: 5302428Abstract: A multiple layer wraparound sleeve having a heat shrinkable backing layer and at least one functional layer has the functional layer as a discrete sheet which is connected to one end of the backing layer, and is of at least sufficient length that, when the sleeve is wrapped around the pipe or other substrate at least twice, the functional layer sheet wraps around the substrate first with its ends overlapping and the backing layer wraps around the functional layer sheet with its ends overlapping. This allows wrappings of reduced thickness to be employed without problems of voids occurring between the functional layer and the substrate.Type: GrantFiled: September 29, 1992Date of Patent: April 12, 1994Assignee: Shaw Industries Ltd.Inventors: Robert E. Steele, Alfredo Andrenacci
