    摘要： 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 partially sealing the air space with one or more sealing members (70), or fans (80) that generate an airflow (82).

    摘要： A method of forming a protective coat (21) about a cutback (18) between pipes (3) forming part of an underwater pipeline (2) provides for laying a thermoplastic sheet (22; 42) on a supporting sheet (23; 27; 40); and winding the thermoplastic sheet (22; 42) and the supporting sheet (23; 27; 40) about the cutback (18) to join the thermoplastic sheet (22; 42) to the cutback (18).
