Abstract

1,207,911. Electric pipe heaters. TRANS CONTINENTAL ELECTRONICS CORP. 7 March, 1968, No. 11099/68. Heading H5H. An electrically heated pipe installation comprises a plurality of heat insulated pipe sections 15 each having a pipe 18, which is electrically connected to a supply so that it will become resistively heated, projecting through opposite ends of a casing 16 filled with heat insulation e.g. polyurethane foam 17. Adjacent pipe ends 18<SP>1</SP> are joined together by welding, by a screw connection or by electrically insulated flanges 21. The pipe connection is embedded in heat insulation 27 which is injected through nipples 26 in a split sleeve 24 mounted on the casings 16 of adjacent pipe sections. A tubular or channelshaped conduit 19 extends through the insulation 17 of each pipe section 15 and carries a lowvoltage supply cable 20. The other supply cable 29 is connected to a tab 30 on pipe end 18<SP>1</SP>. Cables 20, 29 are connected to a transformer. The pipe ends 18<SP>1</SP> may be electrically connected by jumpers. The insulation 17 in each pipe section may be formed by encasing the pipe in a longitudinally split sleeve of preformed polyurethane and then filling the space between the preformed insulation and the outer casing 16 with a material having a higher temperature rating. Two pipe sections of this type are joined by placing a split sleeve of insulation in intimate contact with the pipe coupling, placing the outer split sleeve 24 on the casings 16 of the adjacent pipe sections, and filling with polyurethane foam.
