20090003935 | System and Method for Tightening String Sections to Form a String - The invention relates to a tensioning device in particular for tensioning pipe sections upon an abutment, including a traction element, an adapter, and a tensioning device for applying the tension force, and a sliding brake. | 01-01-2009 |
20100034593 | NOVEL DEPLOYMENT TECHNIQUE FOR OPTICAL FIBRES WITHIN PIPELINE COATINGS - An improved method and system of deploying a pipeline for fiber optic sensing applications. A plurality of pipe sections ( | 02-11-2010 |
20140186121 | FLUSH JOINT PIPE - A pipe has a tubular body with a male end and a female end. The male end has an external surface with a first engagement groove. The female end has an internal surface with a second engagement groove, and an aperture extending from an outer surface of the tubular body to the second engagement groove. The female end receives the male end of another pipe such that the first engagement groove of the male end axially aligns with the second engagement groove of the female end to establish a spline engagement groove having a groove length, L | 07-03-2014 |
20150300529 | PIPE PROCESSING TOOL WITH PIPE DEFORMATION MEMBERS - A pipe processing tool that is configured to deform the end of a pipe so that the circumferential shape of the end of the pipe generally matches the circumferential shape of an adjacent pipe end. Matching the circumferential shapes of the pipe ends is advantageous during a pipe attachment process. The pipe processing tool can include a deformation ring with a plurality of pipe deformation members. Each pipe deformation member faces radially inward and is actuatable in a radial direction toward and away from the center of the deformation ring in order to permit engagement with the pipe. Each pipe deformation member is individually and separately actuatable from the other pipe deformation members so that the circumferential shapes of the pipes can be altered by controlling suitable ones of the pipe deformation members. | 10-22-2015 |
20150345666 | Pipelaying - A method clamps elongate elements in a parallel piggybacked arrangement during subsea laying of the elements. The method has opposed reciprocating jaws for forcing together clamp segments around the elongate elements to assemble a piggybacking clamp that applies clamping forces to the elongate elements. | 12-03-2015 |
20160091114 | IRRIGATION PIPE LAYING MACHINE - An irrigation pipe laying machine for glued or gasketed piped is disclosed. The example pipe laying machine includes a platform including a first end and a second end. The pipe laying machine also includes a clamp configured to grip a portion of a bell end of an upstream pipe to prevent the upstream pipe from moving, a spigot end of the upstream pipe being connected to a second upstream pipe. The pipe laying machine further includes a plunger located adjacent to the second end of the platform and configured to push against a bell end of a downstream pipe causing a spigot end of the downstream pipe to connect to the bell end of the upstream pipe. The plunger is configured to push against the face of the bell end of the downstream pipe when the clamp grips the portion of the bell end of the upstream pipe. | 03-31-2016 |
