Abstract: A heat-delivery apparatus (12) heats a heat-shrinkable sleeve (10) on a pipe (2). The heat-delivery apparatus (12) includes one or more heater elements (20) which define an interior heating surface that surrounds the sleeve (10). An air space is thus defined between the exterior of the sleeve (10) and the interior heating surface. The flow of air, that would otherwise be generated by the step of applying heat, within said air space is controlled or restricted for example by means of fins (50, 50s, 60) that control or restrict the airflow, fully or partially sealing the air space with one or more sealing members (70), or fans (80) that generate an opposing airflow (82).

Abstract: A field joint coating unit for coating a cutback area along a pipeline in which the apparatus includes an extruder having an extrusion outlet positioned adjacent and facing the cutback area so that a protective sheet can be extruded having a width that exceeds an axially extending width of the cutback area, and a mechanism supporting the extruder and its tank, the extrusion outlet, and a roller for compressing the protective sheet onto the cutback area in which the mechanism rotate the extruder, the tank, the extrusion outlet, and the roller about the pipeline as the protective sheet is extruded while maintaining the position of the extrusion outlet relative to the cutback area.
