Description
Technical field
The utility model relates to a kind of radial thermal expansion thermal insulation apparatus, belongs to high-temperature service and pipeline heat preservation technology field.
Background technique
In petrochemical plant in the past, unit scale is little, and the little insulation external protection of specification of equipment and pipeline adopts dull and stereotyped, and the little radial expansion volume of equipment and pipeline specification is little, because inner thermal insulating layer has some compressibilities, the problem of dull and stereotyped and dull and stereotyped lap-joint spalling is not obvious again; Along with unit scale maximizes; high-temperature reactor diameter and connected pipeline specification thereof are increasing; although require overlap joint 50mm in dull and stereotyped and dull and stereotyped hoop seam crossing specification; but due to rivet fixing to it after, lap-joint cannot expand, when high temperature pipe operation; the thermal expansion radially of equipment or pipeline has exceeded the decrement of inner thermal insulating layer; cause protecting sheet lap-joint cracking, and tying up the fracture of the protective layer steel band place of being rigidly connected, sag of protecting coating does not have the effect of protective layer.
Model utility content
The technical problems to be solved in the utility model is: provide one to be convenient to install, can improve heat insulation effect, splicing seams is arranged evenly, surperficial Shunping County, and insulating structure intensity is high, the radial thermal expansion thermal insulation apparatus that overall appearance is effective.
Radial thermal expansion thermal insulation apparatus described in the utility model; comprise protective layer; protective layer is set to corrugated sheet; the tired connecting band of pricking of corrugated sheet periphery; connecting band two ends, by the spring connection of trying to stop people from fighting each other, are pressed from both sides and are connected by J-shaped between connecting band and corrugated sheet, and J-shaped folder is fastened on corrugated sheet; the lap-joint of neighbouring corrugated sheet arranges S clevis, and the two ends of S clevis are fastened on respectively on adjacent corrugated sheet.
In the time installing in hot operation, equipment and pipeline thermal expansion, the space that the crest of corrugated sheet expands to thermal insulation layer, is close to the trough of thermal insulation layer and corrugated sheet and crest, and can be by corrugated sheet spalling; Protecting sheet is connected and fixed up and down with corrugated sheet same form S type folder at corrugated sheet and the employing of the upper and lower lap-joint of corrugated sheet; it is tired on vertical equipment and vertical tube after integral heat insulation that ripple J type is clamping determines steel band having by a side while pricking steel band; external protection is pricked the connection of trying to stop people from fighting each other of joint spring with steel band is tired; stressed even; after insulation, heat insulation layer should be close to coat of metal corrugated sheet splicing seams layout evenly; surface Shunping County, insulating structure intensity is high, and overall appearance is effective.Convenience quick for installation, short construction period, comprehensive benefit is good.
Described spring is tried to stop people from fighting each other and is comprised symmetrically arranged tension frame, and connecting band two ends are fastenedly connected with tension frame respectively, between tension frame, double-screw bolt is set, and double-screw bolt two ends arrange respectively nut, between nut and tension frame inner side, spring is set, and spring housing is contained on double-screw bolt.There is certain flexible scope, ensure the stressed even of each circle steel band, structural stability.
Described corrugated sheet is corrosion resistant plate, and connecting band is steel band, and the wave height of corrugated sheet is 2～5mm, and the pitch of waves is 2～10mm, and thickness is 0.25～1mm.When using, corrugated sheet because wave height and the less protective layer of the pitch of waves can finely contact with inner thermal insulating layer, plays a protective role.
Described S clevis and J-shaped folder are Stainless Steel Band, and S clevis is ripple steel band, and its longitudinal cross-section is S shape, and width is 20～40mm, and thickness is 0.5～1mm, and J-shaped folder inner side surface is corrugated, and its longitudinal cross-section is J-shaped, and width is 20～40mm.Meet the shape of upper and lower corrugated sheet, be convenient to connect, structural relation advantages of simple, milder corrugated sheet has solved high-temperature service and pipeline radial expansion in the time of operation causes the phenomenon of lap-joint's spalling.
The beneficial effects of the utility model are:
Protecting sheet is connected and fixed up and down with corrugated sheet same form S type folder at corrugated sheet and the employing of the upper and lower lap-joint of corrugated sheet, tired on vertical equipment and vertical tube after integral heat insulation have that ripple J type is clamping to be determined steel band it is attached on equipment or pipeline while pricking steel band again by a side, the fixing spring connection of trying to stop people from fighting each other in steel band joint for external protection, there is certain flexible scope, ensure the stressed even of each circle steel band; After insulation, heat insulation layer is close to coat of metal corrugated sheet, and splicing seams is arranged evenly, surperficial Shunping County, and insulating structure intensity is high, and overall appearance is effective.
