Patent number: 7498509Abstract: Connectors for attaching a composite pipe to a service member are described herein. In one embodiment, a connector can include a service end, a slip nut, a slip, a seal carrier, and an energy conductor. The slip nut can be disposed about the outer surface of the pipe and can be engaged by the service end. The slip can be positioned about the outer surface of the pipe and can be engaged by the service end and the slip nut to compress the slip into gripping contact with the pipe. The seal carrier can be positioned in a bore of the pipe at a location radially opposite the slip to resist deformation of the pipe when the slip is compressed into gripping contact with the pipe. The energy conductor can be embedded within and surrounded by a material of the service end for connection with an energy conductor within the composite pipe.Type: GrantFiled: May 21, 2003Date of Patent: March 3, 2009Assignee: Fiberspar CorporationInventors: Arthur D. Brotzell, Stewart H. Fowler, Jr., Chantal Tho

Patent number: 7234410Abstract: A buoyancy control system for controlling the buoyancy of a tube may includes generally tubular length of buoyancy control material having a selected buoyancy characteristic. The length of buoyancy control material may be attached to a section of the length of the tube to adjust the buoyancy of the section of the tube. The length of buoyancy control material may be an integral, coaxial layer of the tube or, alternatively, the length of buoyancy control material may be externally attached to tube. In embodiments in which the length of the buoyancy control material is externally attached, the buoyancy control material may have a longitudinal axis that is spaced-apart from a longitudinal axis of the tube.Type: GrantFiled: April 14, 2005Date of Patent: June 26, 2007Assignee: Fiberspar CorporationInventors: Peter A. Quigley, Stephen C. Nolet, Thomas W. Wideman

Publication number: 20050189029Abstract: A spoolable pipe is disclosed, the spoolable pipe having an internal pressure barrier formed about a longitudinal axis, and a reinforcing layer(s) enclosing the internal pressure barrier. In one embodiment, the reinforcing layer(s) can include fibers having at least a partial helical orientation about approximately thirty and about approximately seventy degrees relative to the longitudinal axis, and, the wall can include at least one external layer enclosing the reinforcing layer(s) and having a permeability at least ten times greater than the permeability of the internal pressure barrier. The reinforcing layer(s) can further include a coating. The pipe can also include an energy conductor(s) integrated with and/or located between the internal pressure barrier and/or the reinforcing layer(s).Type: ApplicationFiled: December 13, 2004Publication date: September 1, 2005Applicant: Fiberspar CorporationInventors: Peter Quigley, Michael Feechan

Patent number: 6857452Abstract: A spoolable composite tube capable of being spooled onto a reel for storage and for use in oil field applications. The spoolable tube exhibits unique anistropic characteristics that provide improved burst and collapse pressures, increased tensile strength, compression strength, and load carrying capacity, while still remaining sufficiently bendable to be spooled onto a reel in an open bore configuration. The spoolable composite tube can include an inner liner, an interface layer, fiber composite layers, a pressure barrier layer, and an outer protective layer. The fiber composite layers can have a unique triaxial braid structure.Type: GrantFiled: June 12, 2003Date of Patent: February 22, 2005Assignee: Fiberspar CorporationInventors: Peter A.
