Abstract
A die for casting junctions of a coating of a pipeline is configured to be coupled to the pipeline to form an annular shaped closed compartment about a tubular joint portion comprising a tubular wall, which extends about a designated axis; a plurality of centering devices configured to align the axis of the tubular wall with a longitudinal axis of the pipeline; two annular walls arranged respectively at the opposite ends of the tubular wall; and two pluralities of vent openings arranged along the tubular wall respectively at each of the annular walls; and at least one feeding port configured to supply polymer material into the closed compartment.
Claims23
A die comprising:
- a tubular wall which extends about an axis;
- a plurality of centering devices configured to align the tubular wall such that the axis of the tubular wall with a longitudinal axis of a pipeline;
- a first annular wall arranged at one end of the tubular wall;
- a first plurality of vent openings arranged along the tubular wall within a first designated distance of the first annular wall, wherein each of the first plurality of vent openings comprises:
- a hole defined by the tubular wall, and
- an insert of porous material which is configured to enable air to pass through the hole and stop a flow of polymer material;
- a second annular wall arranged at an opposite end of the tubular wall;
- a second plurality of vent openings arranged along the tubular wall within a second designated distance of the second annular wall, wherein each of the second plurality of vent openings comprises:
- a hole defined by the tubular wall, and
- an insert of porous material which is configured to enable air to pass through the hole and stop a flow of polymer material;
- and
- at least one feeding port configured to supply polymer material into an annular-shaped closed compartment formed about a tubular joint portion of the pipeline when the die is coupled to the pipeline.
