Description
Technical field
The utility model relates to arrive a kind of insulating tube field, and in particular to arrive a kind of polyurethane heat-insulation steel pipe.
Background technique
Polyurethane heat-insulation steel pipe is after heat preservation method working process, under the action of different operating environment and outer medium
Temperature and surface temperature meet or reach the steel pipe of requirement in guarantee working steel tube.Utilidor is widely used in liquid
The transmission pipeline network of body, gas, chemical pipeline heat insulating work petroleum, chemical industry, central heating network, ventilating duct of central air conditioner, city
Political and ideological work journey etc..
When storing polyurethane heat-insulation steel pipe, the polyurethane insulation coating between polyethylene protection pipe and working steel tube is easy quilt
Mouse is destroyed, while in pipeline welding, and the heat for welding generation is easy polyurethane insulation coating and burns out.
Utility model content
The technical problem to be solved by the utility model is to one kind convenient for storage, can be effectively protected in welding poly-
The polyurethane heat-insulation steel pipe of urethane insulating layer.
To achieve the goals above, technical solution provided by the utility model is：
A kind of polyurethane heat-insulation steel pipe, including working steel tube, working steel tube outer cover are equipped with polyethylene protection pipe, polyethylene
Polyurethane insulation coating is filled between protection pipe and working steel tube, the both ends of working steel tube extend to outside polyethylene protection pipe,
It is arranged with hollow lantern ring on the both ends of working steel tube, inner edge is fixedly installed on the inner edge of lantern ring and is connect with working steel tube outer rim
The cotton ring of touching has been uniformly arranged multiple apopores on the inner edge of lantern ring, is provided in the outer rim of lantern ring and internal is connected to it
Water injection pipe, the side of lantern ring towards polyethylene protection end surfaces is fixedly installed multiple to be consolidated with what polyethylene protection pipe outer rim contacted
Fixed board, fixed plate are bolted with polyethylene protection pipe.
Specifically, being provided with capping on the water injection pipe.
Specifically, the polyethylene protection pipe and working steel tube are concentric.
Compared with prior art, the beneficial effects of the utility model are：
The utility model, structure is simple, easy to use, using lantern ring will be exposed to working steel tube and polyethylene protection pipe it
Between polyurethane insulation coating blocked into shape, prevent mouse destroy polyurethane insulation coating, meanwhile, welding when into lantern ring inside plus
Enter water, water soaks cotton ring after apopore, prevents the temperature of working steel tube when welding excessively high and makes and working steel tube

Specific embodiment
As shown in Figure 1, a kind of polyurethane heat-insulation steel pipe, including working steel tube 1,1 outer cover of working steel tube are equipped with polyethylene
Protection pipe 3, the polyethylene protection pipe 3 and working steel tube 1 are concentric.It is filled between polyethylene protection pipe 3 and working steel tube 1
Polyurethane insulation coating 2, the both ends of working steel tube 1 extend to outside polyethylene protection pipe 3, are arranged on the both ends of working steel tube 1
There is hollow lantern ring 4, the cotton ring 5 that inner edge is contacted with 1 outer rim of working steel tube is fixedly installed on the inner edge of lantern ring 4, lantern ring 4
It has been uniformly arranged multiple apopores 9 on inner edge, has been provided in the outer rim of lantern ring 4 and its internal water injection pipe 6 being connected to, the water filling
Capping is provided on pipe 6.The side of lantern ring 4 towards polyethylene protection end surfaces is fixedly installed multiple and polyethylene protection pipe 3
The fixed plate 7 of outer rim contact, fixed plate 7 are connect with polyethylene protection pipe 3 by bolt 8.
When being stored, lantern ring 4 will be exposed to the polyurethane insulation coating between working steel tube 1 and polyethylene protection pipe 32
It is blocked into shape, can effectively prevent mouse from destroying polyurethane insulation coating 2.When pipeline welds, water, lantern ring 4 are added into lantern ring 4
Interior water is soaked cotton ring 5 by apopore 9, and the working steel tube 1 when the cotton ring 5 being soaked in water can be to welding drops
Temperature processing, prevents the end of the polyurethane insulation coating contacted with working steel tube 12 to be burned.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
