Insulation and/or heating and/or colling system with prefabricated elements separated from the pipes and components of the plants through which process fluids are flowing

摘要

System for the insulation of pipes, tanks and plant components which features independent, prefabricated modular elements having the form of a duplex pipe (2, 3) forming a jacket (4), the inner tube (2) closely enveloping the of small or medium diameter pipe (1) or having the form of a pipe (13) fitted with a plate (14) in touch with the outer surface (18) of large diameter pipes or equipments, or having the form of hollow spaces (27) around the equipment (26), so that the fluid heating or cooling the process fluid flows in single or multiple sequences through the jacket (4) as well as through the pipe (13) and the hollow spaces (27) and that the duplex pipes (2, 3), the pipes (13, 14) or hollow spaces (27) present an external insulating layer (5, 16, 25) topped by a finishing skin (6, 15, 28). <IMAGE> <IMAGE>
