摘要
Pipes (1) used for transporting hot water or other heated fluids are supplied with a thermal insulation jacket protected by an outer covering (3). A joint between pieces of such pipe is made in the following way. The insulation (2) and outer cover (3) are removed over a short distance from the end of each piece of pipe. The two pieces of pipe are then joined together by butt welding. The gap between the two sections of thermal insulation is then filled with two half shells of insulating material. Finally these half shells of insulation are covered with half shells of a protective layer which is butt welded along circumferential seams (4) to the ends of the existing protective cover (3) and these outer half shells are also welded to each other along the longitudinal seam (5). The edges of the welded material are chamfered to produce a flush weld.
