Abstract

There is provided a method of increasing the collapse resistance of a region of a flexible pipe. The method includes providing a flexible pipe body having a plurality of pipe layers and deploying a reinforcement insert into a bore of the flexible pipe body through a free end thereof. A clamping force is applied to an external surface of the flexible pipe body at a location corresponding to the reinforcement insert. The reinforcement insert opposes radially inwards collapse of at least one layer of the flexible pipe body as a result of the clamping force. After removing the clamping force, the method includes either leaving the reinforcement insert within the bore of the flexible pipe body; or disassembling or mechanically retracting the reinforcement insert and retrieving it through the free end of the flexible pipe body.

Abstract

A reinforced thermoplastic pipe having a polymeric barrier layer formed about a longitudinal axis; at least one first non-metallic reinforcement layer configured to carry an internal pressure load surrounding the polymeric barrier layer; at least one second non-metallic reinforcement layer configured to carry an axial load surrounding the at least one first reinforcement layer; and a polymeric cover layer surrounding the at least one second reinforcement layer. At least one of the first or second reinforcement layers is braided. In some embodiments, the lay angles of the first and second reinforcement layers are selected to reduce the axial compression force in the pipe in a constrained application. In another embodiment, an interior helical metallic layer around which the polymeric barrier layer is formed, the interior layer being an interlocked metallic carcass, a flat helically wound strip or a helically wound wire.

Abstract

A system for monitoring leakage in a pipe system including a pipe, a flexible tube extending through an inside of the pipe, an end fitting assembly connecting each end of the tube to a corresponding end of the pipe which creates an annulus and a monitoring system for detecting leakage from the tube into the annulus. A method for creating multiple flow paths in an existing pipe is also provided.

Abstract

A tube splicing machine is provided which includes a frame on which a die holder is located. A swaging die is removably mounted in the die holder, and the die holder includes a main plate and a top plate that is removably connected to the main plate. A die holding opening is defined through a portion of the main plate and the top plate in which the swaging die is inserted. The swaging die includes two die parts that together define a die opening and are separable along a mid-line of the die opening. A splice fitting engagement plate with a splice fitting engagement portion is located on the frame, with the splice fitting engagement plate having an opening or an openable top to allow removable connection to a splice fitting. An actuator is connected between the splice fitting engagement plate and the die holder for moving the splice fitting engagement plate relative to the die holder from an initial position to a swaged position, in order to swage the splice fitting onto a length of hose or tubing. This allows a splice fitting to join quasi-endless lengths of hose or tubing in a simple manner.
