Abstract
A kind of fireproof heat insulating pipe, including working steel tube, fireproof thermal-insulation layer and outer jacket；The fireproof thermal-insulation layer is made of calcium silicates internal layer and polyurethane foam plastics outer layer, the calcium silicates internal layer is two-piece type tile fragment structure, it is fastened on outside working steel tube, and position is bonded by litaflex joint filling in two panels tile fragment docking site, with working steel tube outer wall, the polyurethane foam plastics outer layer is filled between calcium silicates internal layer and outer jacket.The utility model reaches the purpose for promoting the heat preservation pipe prefabricated fire retardant performance of high temperature by the optimization to heat insulation layer structure.
Description
Technical field
The utility model relates to a kind of fireproof heat insulating pipes, belong to insulating tube technical field.
Background technique
Insulating tube is the abbreviation of insulated piping, for the conveying of liquid, gas, in petroleum, chemical industry, space flight, military affairs, concentration
It is widely used in the adiabatic heat-insulation engineering of the pipelines such as heat supply, central air-conditioning, municipal administration.In the prior art, high temperature is heat preservation pipe prefabricated
It is made of working steel tube, insulating layer and outer jacket, there is good heat insulating, securely and reliably, the advantages such as project cost is low, due to it
Insulating layer uses rigid polyurethane foam, and polyurethane foam plastics is isocyanates and the aggregated foaming of hydroxy compounds
It is manufactured, and can make polyurethane foam plastics that there is certain flame retardant property, still by adding fire retardant in foaming formulation
When selecting fire retardant, in addition to considering its flame retardant effect to product, also need to consider to be added fire retardant to foam process and
Influence to product physical property, therefore there is significant limitation.In addition, as city integrated piping lane is in civilian infrastructure
Using with development, higher requirement is proposed to the fire retardant performance of insulating tube, therefore, a kind of fireproof heat insulating pipe gesture is innovated and exists
It must go.
Utility model content
The utility model provides a kind of fireproof heat insulating pipe, it is intended to by the optimization to heat insulation layer structure, reach and promote high temperature
The purpose of heat preservation pipe prefabricated fire retardant performance.
To achieve the above objectives, the present invention adopts the following technical solutions:
A kind of fireproof heat insulating pipe, including working steel tube, fireproof thermal-insulation layer and outer jacket；The fireproof thermal-insulation layer is by calcium silicates
Internal layer and polyurethane foam plastics outer layer composition, the calcium silicates internal layer are two-piece type tile fragment structure, are fastened on outside working steel tube
Face, and in two panels tile fragment docking site, be bonded with working steel tube outer wall position and pass through litaflex joint filling, the polyurethane foam
Plastic outer layer is filled between calcium silicates internal layer and outer jacket.
Above-mentioned fireproof heat insulating pipe, the outer jacket use spiral steel pipe structure, are suitable for making somebody a mere figurehead or in city integrated piping lane
Middle laying.
Above-mentioned fireproof heat insulating pipe, the outer jacket are suitable for applying direct buried using the oily anti-corrosion jacket structure of two cloth three
If.
The utility model is a kind of fireproof heat insulating pipe, and insulating layer is designed as calcium silicates internal layer and polyurethane foam plastics by it
Outer layer composite construction, not only ensure that the thermal insulation property of pipeline, but also improve the fire retardant performance of pipeline, make the high temperature resistant of pipeline
Grade reaches 350 °C, the laying suitable for high temperature steam pipeline；The utility model can match three oil of spiral steel pipe structure or two cloth
The outer jacket of anti-corrosion jacket structure, therefore cannot be only used for aerial or laid in city integrated piping lane, it can also be used to underground is straight
The laying in pipe laying road.It can be seen that the utility model by the optimization to heat insulation layer structure, reaches and promotes high temperature prefabricated thermal insulation
The purpose of pipe fire retardant performance.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is A-A the schematic diagram of the section structure in Fig. 1.
Each list of reference numerals in figure are as follows: 1, working steel tube, 2, fireproof thermal-insulation layer, 2-1, calcium silicates internal layer, 2-2, polyurethane foam
Foam outer layer, 2-3, litaflex, 3, outer jacket.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail.
Referring to Fig. 1, Fig. 2, the utility model is a kind of fireproof heat insulating pipe, it includes working steel tube 1,2 and of fireproof thermal-insulation layer
Outer jacket 3；The fireproof thermal-insulation layer 2 is made of calcium silicates internal layer 2-1 and polyurethane foam plastics outer layer 2-2, the calcium silicates
Internal layer 2-1 is two-piece type tile fragment structure, is fastened on 1 outside of working steel tube, and outside two panels tile fragment docking site and working steel tube
Wall is bonded position by litaflex 2-3 joint filling, the polyurethane foam plastics outer layer 2-2 be filled in calcium silicates internal layer 2-1 and
Between outer jacket 3.Since calcium silicate board is non-ignitable A1 grades of material, there is good fire protecting performance, and polyurethane foam plastics has
Good thermal insulation property, therefore the utility model not only ensure that the thermal insulation property of pipeline, but also improve the fire protection flame retarding of pipeline
Can, so that the high temperature resistant grade of pipeline is reached 350 °C, the laying suitable for high temperature steam pipeline；The utility model can also match not
Same outer jacket structure, is suitable for different pipeline laying modes, specific embodiment is as follows:
Embodiment one: fireproof heat insulating pipe described in the utility model, outer jacket 3 use spiral steel pipe structure, are suitable for frame
Sky is laid in city integrated piping lane.
Embodiment two: fireproof heat insulating pipe described in the utility model, outer jacket 3 use the oily anti-corrosion jacket structure of two cloth three,
Suitable in direct buried laying.
