Abstract
A polymer-lined fluid transmission line includes various structures, including a first polymer-lined pipe, a second polymer-lined pipe, and one or more sleeve retainers installed at a pipe junction between the polymer-lined pipes. Among other things, the sleeve retainers may include one or more protuberances to frictionally engage the polymer-lined pipes or a one or more portions that protrude into a space between the polymer-lined pipes to help retain and protect polymer sleeves.
Claims20
A sleeve retainer for a polymer-lined pipe, the sleeve retainer comprising:
- a tubular body comprising a first terminal end and a second terminal end and comprising an interior surface and an exterior surface defining an external diameter;
- the first terminal end of the tubular body configured to be inserted into the polymer-lined pipe;
- and
- a flange protruding radially outward from the second terminal end, the flange comprising:
- a flange base connected to the tubular body;
- a flange distal edge spaced radially outward from the flange base;
- a first surface that transitions to the exterior surface of the tubular body at the flange base and a second surface that transitions to the interior surface of the tubular body at the flange base;
- and
- a chamfer in the first surface that transitions from a first position between the flange distal edge and the flange base to the distal edge of the flange.

- the first terminal end of the tubular body configured to be inserted into a first polymer-lined pipe and the second terminal end of the tubular body configured to be inserted into a second polymer-lined pipe;
- and
- a flange protruding radially outward from the exterior surface at a position between the first and second terminal ends, the flange comprising:
- a flange base connected to the tubular body;
- a flange distal edge spaced radially outward from the flange base;
- a first surface, a second surface, and a thickness between the first and second surface;
- the first surface and the second surface each transitioning from the exterior surface of the tubular body to the flange distal edge on opposing sides of the flange;
- a first chamfer in the first surface that transitions to the flange distal edge;
- and
- a second chamfer in the second surface that transitions to the flange distal edge.
