Abstract
Passed by one's way trombone slide repaired mouth protection device the utility model discloses a kind of steel steam heat preserving pipeline; including the 3PE asepticised outer layers being arranged on joint coating on pipeline; layer of polyethylene electric heating melting set is provided with outside 3PE asepticised outer layers, polyethylene electric heating melting set is covered in 3PE asepticised outer layers and covers the pipeline outer wall on 3PE asepticised outer layers periphery simultaneously；This joint coating on pipeline protection device solves the problems, such as at pipe in pipe pulling construction repaired mouth that anticorrosive coat is fragile, perishable when using.
Description
Technical field
The utility model belongs to joint coating on pipeline protection field, and more specifically to a kind of steel steam heat preserving pipeline is passed by one's way drawing
Pipe repaired mouth protection device.
Background technology
In the work progress of municipal jet chimney, when be commonly encountered pipeline and pass by one's way construction, for avoid brokenly road construction to traffic,
Road has an impact, and is typically chosen trombone slide and passes by one's way.During pipe in pipe pulling construction, joint coating on pipeline is in the most weak place of whole pipeline,
During trombone slide, once the 3PE anticorrosive coats damage at repaired mouth, can directly affect construction quality, cause outer tube to corrode, reduce pipe
Line service life.
Utility model content
The purpose of this utility model is to provide a kind of steel steam heat preserving pipeline and passed by one's way trombone slide repaired mouth protection device, solves to draw
At pipe construction repaired mouth anticorrosive coat it is fragile, use when it is perishable the problem of.
A kind of steel steam heat preserving pipeline of technical solutions of the utility model is passed by one's way trombone slide repaired mouth protection device, including is arranged on pipe
3PE asepticised outer layers on road repaired mouth, layer of polyethylene electric heating melting set, the polyethylene are provided with outside the 3PE asepticised outer layers
Electric heating melting set is covered in 3PE asepticised outer layers and covers the pipeline outer wall on 3PE asepticised outer layers periphery simultaneously.
Preferably, the 3PE asepticised outer layers include the adhesive layer of nexine, the clinkery epoxy powder layer of centre and outer layer
Polyethylene layer.
The utility model technology beneficial effect：
A kind of steel steam heat preserving pipeline of technical solutions of the utility model is passed by one's way trombone slide repaired mouth protection device, because joint coating on pipeline
Place's 3PE external anti-corrosion layers have the protection that polyethylene electric heating melting covers, therefore avoid and preventing corrosion of repaired mouth layer is caused brokenly in pipe in pipe pulling construction
It is bad；Polyethylene electric heating melting set is tightly pasted in 3PE asepticised outer layers, during pipe network long-term use, is avoided because at repaired mouth
The phenomenon that anticorrosive coat is weak and causes outer tube to corrode, substantially increases bypass pipeline service life；The simple side of device installation
Just, as 3PE anticorrosive constructions can be installed, without increasing work post, the span of control is small.
Brief description of the drawings
Fig. 1 is that a kind of steel steam heat preserving pipeline of the utility model is passed by one's way trombone slide repaired mouth protection device structural representation.
Embodiment
For ease of skilled artisan understands that technical solutions of the utility model, new to this practicality in conjunction with Figure of description
Type technical scheme is described further.
The trombone slide repaired mouth protection device as shown in figure 1, a kind of steel steam heat preserving pipeline is passed by one's way, including it is arranged on joint coating on pipeline 1
On 3PE asepticised outer layers 2, layer of polyethylene electric heating melting set 3, the polyethylene electric heating are provided with outside the 3PE asepticised outer layers 2
Molten set 3 is covered in 3PE asepticised outer layers 2 and covers the pipeline outer wall 4 on the periphery of 3PE asepticised outer layers 2 simultaneously, the 3PE asepticised outer layers 2
The polyethylene layer of adhesive layer including nexine, middle clinkery epoxy powder layer and outer layer.
In pipe in pipe pulling construction, before pipeline welding, a strata is covered on the outer tube of direct-burried steel-sleeve steel steam insulation pipe
Ethene electric heating melting set；Pipeline complete to weld and detect it is qualified after, first butt welding mouth carries out anti-corrosion with 3PE layers, then that polyethylene is electric
Hot melt oversleeve is enclosed on the outer layer of 3PE anticorrosive coats；With high-temperature baking, polyethylene electric heating melting set is tightly pasted in 3PE corrosion-resistant
Outer layer, it is allowed to turn into an entirety with pipeline.
Utility model is exemplarily described above in conjunction with accompanying drawing for technical solutions of the utility model, it is clear that this practicality
New specific implementation is not subject to the restrictions described above, and is carried out as long as employing methodology and technical scheme of the present utility model
Various unsubstantialities improve, or it is not improved the design of utility model and technical scheme are directly applied into other occasions,
Within the scope of protection of the utility model.
