Description
Technical field
The present invention relates to a kind of air heat insulation (or vacuum heat-insulation) high-temperature pipe fixed support, particularly high-temperature pipe fixing of major diameter, long-distance sand transport.The invention still further relates to high-temperature pipe fixation method.
Background technique
Conveyance conduit is when running into temperature and changing, have phenomenon of expanding with heat and contract with cold, therefore pipeline can produce displacement, for the major diameter high-temperature pipe (such as more than DN1000) of long-distance sand transport, the negative effect that pipeline brings because of phenomenon of expanding with heat and contract with cold is larger, and pipeline large displacement occurs and can damage whole conveyance conduit.For avoiding conveyance conduit that large displacement occurs, ensure the stability of heat supply pipeline pipe-line system under external force, local weak component in protective conduit system, needing the certain position in pipeline is arranged sincere buttress, to carry out to pipeline pressures fixing.In order to be fixed conveyance conduit, the relevant position normally at pipeline in prior art arranges cement anchor block, utilizes cement anchor block to fix pipeline.But adopting cement anchor block fixing tube to there is the volume of anchor block, comparatively large (such as, according to design code, when heat supply pipeline is DN1000, the volume of cement anchor block is 9m
3), by the spatial constraints that road piping is comprehensive, cannot realize, and there is waste of material, cost is high, primary concreting difficulty, the defects such as long construction period; In addition, when adopting cement anchor block fixing tube, because it is made up of concrete buttress and location of pipeline ring, location of pipeline ring directly contacts with concrete, the heat of working steel tube directly can be conducted to concrete buttress by location of pipeline ring, cause concrete buttress expanded by heating uneven and break, losing the fixation to pipeline; In addition, because the thrust thrust that it produces compared to small diameter pipeline produced when large diameter high-temperature pipe Yin Wendu changes is larger, thrust can reach tens tons, and pipeline fixing bracket of the prior art is often difficult to bear so large thrust.
Summary of the invention
For the above-mentioned problems in the prior art, the invention provides a kind of new high-temperature pipe fixed support, it effectively can fix high-temperature pipe, do not limit by road piping general space, and load ability is large, effectively can reduce heat bridge effect, easy construction, cost are low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of high-temperature pipe fixed support, its special way is: comprise an outer shroud, two annular inner ring, two outer steel pipes, described outer shroud is primarily of two blocks of annular side ring plates and the inner ring plate be fixedly installed between two blocks of side ring plates and outer ring plate composition, two described outer steel pipes are fixedly connected on the both sides of the axis of described outer shroud respectively, described outer shroud and outer steel pipe are sleeved on the outside of working steel tube, described inner ring is set with and is fixed on the outside of working steel tube, two inner ring lay respectively at the both sides of described outer shroud and are positioned at outer steel pipe, thermal-protective coating A is provided with between described outer shroud and the outer wall of working steel tube, all gap is left between described inner ring and outer shroud and between inner ring and outer steel pipe, heat insulation layer B is provided with between described outer steel pipe and working steel tube.
In the present invention, be fixed together due to two inner ring and working steel tube and can not be moved in the restriction being axially subject to outer shroud, thus working steel tube can not be moved, being fixed.The thermal-protective coating A arranged in the present invention, for preventing the heat transmission between working steel tube and outer shroud, prevents outer shroud temperature distortion.Heat insulation layer B set between outer steel pipe and working steel tube in the present invention plays insulation and supports the effect of outer steel pipe.By the setting of heat insulation layer, effectively can block the heat transfer between working steel tube and outer shroud and outer steel pipe, can heat bridge effect be greatly reduced.
Further, the outside of described outer steel pipe is set with apart from described outer shroud certain distance the stiffening ring be fixed together with it, is fixedly connected with some strengthening rib A between described outer shroud and stiffening ring.Because working steel tube can expand with heat and contract with cold when temperature changes, described outer shroud can be subject to very large thrust, the position that outer steel pipe is connected with outer shroud is easy to be fractureed under the effect of this thrust, by arranging stiffening ring and strengthening rib A can effectively prevent outer steel pipe from fractureing, ensure fixed support use safety; Meanwhile, stiffening ring is sleeved on outer steel pipe outside, prevents outer steel pipe from deforming by stiffening ring.
In order to improve the bulk strength of outer shroud, between the inner ring plate of described outer shroud and outer ring plate, be fixedly installed some uniform strengthening rib C.
In order to improve the load ability of inner ring, between described inner ring and working steel tube, be fixedly installed some uniform strengthening rib B.
In order to avoid heat transmission, in the gap between described inner ring and outer shroud, be provided with high-strength heat-insulation layer.
In order to improve the intensity of outer steel pipe, described outer steel pipe outer cover is equipped with reinforcement steel pipe, and described reinforcement steel pipe is fixedly connected with outer steel pipe and outer shroud.
Present invention also offers a kind of fixation method of high-temperature pipe, it utilizes above-mentioned high-temperature pipe fixed support to be fixed high-temperature pipe.
The invention has the beneficial effects as follows: structure of the present invention is simple, and intensity is high, use reliable, easy construction, practical, it effectively can fix high-temperature pipe; Its intensity of the outer shroud of the fabricated structure adopted in the present invention is high, and load ability is large, can bear larger pipeline thrust, can adapt to the high thrust that major diameter high-temperature pipe produces because of temperature variation, and the outer shroud of fabricated structure is easy to process, saves material; The present invention strengthens steel pipe, stiffening ring, strengthening rib etc. by arranging, and effectively ensure that support bracket fastened overall construction intensity, thus ensure that the Security of pipe-line system; The present invention is by structural design unique between inner and outer rings, and the heat insulation layer set by utilization, the heat that effectively can block service pipe, to the conduction of outer shroud and outer steel pipe, effectively reduces heat bridge effect.Overall structure of the present invention is simple, and volume is little, not by spatial constraints, and cost of the present invention is low, when being fixed same major diameter high-temperature pipe, when adopting the fixed support in the present invention, its cost is adopt cement anchor block 1/10th, therefore, it is possible to greatly reduce construction investment.
