The development of cause, the construction scale of heat distribution pipe network is increasing, using more and more extensive.Heat distribution pipe network build when, pipeline into
This and heat waste are a highly important indexs of pipe-line construction.Attention with various circles of society to environmental protection, for region
The coal-fired arcola of heat supply will be removed gradually, and required heat energy will use long heat transport net centralizedly supply by power plant, therefore prefabricated built on stilts
The heat waste control requirement of composite thermal-insulating pipe will be higher.
Major part overhead heat distribution pipeline generally uses live insulation at present, for this working method, exists a lot
Weak point, first, insulation quality is difficult control, because the working environment limitation of scene insulation, heat insulation work personnel are often very
Hardly possible carries out insulation operation in strict accordance with construction technology, and danger coefficient is high when operating, and aerial pipeline is sometimes located at very high-order
Put and be related to work high above the ground, be susceptible to personnel casualty accidentses;In addition, the inefficiency of this working method, cross-over pipe
Heat insulation work is frequently necessary to scaffolding, and operating personnel often will up and down take material, and time-consuming, long in time limit, cost is also high.
Prefabricated built on stilts composite thermal-insulating pipe can solve these problems, what existing prefabricated built on stilts insulation pipe structure inside used
It is steel pipe, wraps up inorganic layer, organic layer, outer protection tube successively from the inside to the outside.Their inorganic layer segment uses multilayer calcium silicates
Tile fragment, has the disadvantage that calcium silicates tile fragment seam is more, and heat easily outwards scatters and disappears from seam crossing, therefore it is required that calcium silicates watt heat-insulation layer compared with
It is thick.Further, since the outer protection tube of this kind of pipeline uses perspex steel protective layer, there was only 5- in the case of outdoor exposing to the sun and rain
The service life of 7 years, and have substantial amounts of organic irritative gas pollution environment during the making of lucite steel jacket.In order to subtract
Few heat waste of the steam in transmitting procedure, the prefabricated built on stilts compound of thermal loss can be significantly reduced we have developed a kind of
Insulating tube.
The content of the invention
The purpose of this utility model be in order to solve heat-insulation layer tile fragment described above that current heat distribution pipeline is present it
Seam is easily leaked, the low problems of service life, there is provided a kind of prefabricated built on stilts composite thermal-insulating pipe.
In order to reach above-mentioned utility model purpose, the utility model uses following technical scheme:
A kind of prefabricated built on stilts composite thermal-insulating pipe, the composite thermal-insulating pipe include successively from the inside to the outside core pipe, inorganic insulating layer,
