A sectional heat insulating jacket is a removable, repeatedly used for various process equipment heat(sound-) insulation product<been made of a set of the insulation sections ( 2 ), which are separated at the stage of installation by the assembling joints ( 22 ) and are connected among themselves in an organic whole using the connecting means ( 24 ). The insulating sections ( 2 )-polyhedral, closed protective housings ( 4 ), are formed by thread-stitched seams ( 6 ) and comprise the bottom ( 8 ), upper ( 10 ), and lateral ( 12 ) flexible layers. There is a middle heat (sound)insulation-forming layer, placed inside the housing ( 4 ). The layers ( 8 ), ( 10 ), and ( 12 ) are fastened among themselves by the fastening means ( 16 ), consisting of the fastening rod ( 18 ) and the fixing means ( 20 ) and providing invariable thickness of the insulation section ( 2 ) and its all layers mutual work during thermal deformation. The connecting means ( 24 ) comprise the studs ( 26 ) fixed on the fastening rods ( 18 ), and the plates-clamps ( 28 ), which are able to be turned around on one of the studs ( 26 ) and to fix a mutual positions of the fastening rods ( 18 ) and, consequently, a mutual positions of the adjacent insulation sections ( 2 ) at a stage of installation, under an equipment heating process and after the assembling joint ( 22 ) "self-sealing", i.e. at a stage of operation. The assembling joints ( 22 ) "self-sealing" effect is provided due to the insulation sections shape ( 2 ) and due to the offered method for calculation of the assembling joints ( 22 ) widths at levels of the upper ( 10 ) and bottom ( 8 ) flexible layers of the insulation sections ( 2 ) in longitudinal and transverse directions.
