Another purpose of the utility model is to provide a kind of steam injection pipeline imbedded and fastened insulating structure, and after the steam injection pipeline insulation, its overall structure is more stable; Can reduce vapor evolution, reduce and scald risk, improve safety coefficient.
The purpose of the utility model is achieved in that a kind of steam injection pipeline imbedded and fastened insulating structure, and this imbedded and fastened insulating structure is to be made up of the circular body that the corresponding buckle of two semicircle tube columns is combined into; Said each semicircle tube column all is to be made up of integrated internal layer and skin; The setting that interlaces vertically of said internal layer and skin forms internal layer and is first protuberance with respect to an outer end, and is first recess with respect to the outer the other end; Said internal layer, forms internal layer and is second protuberance with respect to an outer side, and be second recess with respect to outer opposite side along the setting that circumferentially interlaces with outer.
In a preferred embodiments of the utility model, the internal diameter of said semicircle tube column is identical with the steam injection pipeline diameter.
In a preferred embodiments of the utility model, the length of said semicircle tube column is 600mm; The wall thickness of semicircle tube column is 80mm; The axial length of said first protuberance and first recess is 15mm; The circumferential lengths of said second protuberance and second recess is 15mm.
From the above mentioned; This steam injection pipeline imbedded and fastened insulating structure overcomes the defective of existing technology; This insulating structure has increased the area of contact between the thermal insulating material, makes the thermal insulating material joint connected by " single face " and becomes " multiaspect " connection, and the slit becomes " broken line type " by " straight line type " therebetween; Reduce heat loss, made better heat preservation; Connect through imbedded and fastened between the thermal insulating material on the steam injection pipeline, make insulating structure more firm; Connect through imbedded and fastened between the thermal insulating material, cancelled the construction of heat preservation slurry joint filling or double-deck tooled joint, simplified operation and reduced materials; " multiaspect " contact of thermal insulating material joint imbedded and fastened structure, the characteristics in " broken line type " slit, it is tightr that material is connected, and reduces vapor evolution, reduced the scald probability, improved safety coefficient; When steam injection pipeline received thermal stretching, two-way overlay structure can keep the sealing of pipeline, when reducing thermal loss, had reduced the use amount of thermal insulating material.
