Abstract
The utility model relates to compound pipes, in particular to a corrosion resistant spiral reinforced rib compound pipe which solves the problems that an existing stainless steel spiral welding pipe is high in cost, and a common steel spiral welding pipe can be sucked flat and deform easily. The corrosion resistant spiral reinforced rib compound pipe comprises a stainless steel pipe arranged on an inner layer and a polyethylene plastic pipe arranged on an outer layer. A layer of iron pipe is fixedly attached between the stainless steel pipe and the polyethylene plastic pipe. The side wall of the stainless steel pipe, the side wall of the polyethylene plastic pipe, and the side wall of the iron pipe extrude spiral reinforcing ribs outward. The corrosion resistant spiral reinforced rib compound pipe is reasonable and reliable in structural design and effectively reduces machining cost. Moreover, the rigidity of the compound pipe can eliminate the occurrence of the phenomena of sucking flat and deformation at negative pressure working time. The corrosion resistant spiral reinforced rib compound pipe has the advantages of being simple in structure, convenient to machine and long in service life.
Description
Technical field
The utility model relates to composite pipe, is specially a kind of anticorrosive spiral reinforcing rod composite pipe.
Background technique
At present, domestic colliery draws out methane has following several pipeline with pipe: vinyl tube, polyvinyl chloride pipe, common steel tube, soak and mould plastic-coated steel, Stainless Steel Tube.
The present domestic plain carbon steel spiral welded pipe that is mostly, do not reach the requirement of negative pressure work due to the intensity of the thin-walled spiral welded pipe in existing market, be only applicable to positive airway pressure, fluid conveying use, be used for negative pressure work and easily inhale flat distortion, and the cost of stainless steel spiral welded pipe is higher, so the stainless steel spiral welded pipe is not applied in gas drainage system of coal mine.
Summary of the invention
The utility model is higher and adopt the plain carbon steel spiral welded pipe to have the problem of easily inhaling flat distortion in order to solve existing stainless steel spiral welded pipe cost, and a kind of anticorrosive spiral reinforcing rod composite pipe is provided.
The utility model is to adopt following technological scheme to realize: anticorrosive spiral reinforcing rod composite pipe, comprise Stainless Steel Tube and the outer vinyl tube that arranges that nexine arranges, between Stainless Steel Tube and vinyl tube, laminating is fixed with one deck iron pipe, and the sidewall of Stainless Steel Tube, vinyl tube and iron pipe is along the outside extrusion spiral shape of three's axis stiffening rib.
After Stainless Steel Tube, vinyl tube and iron pipe is compound, when cost declines to a great extent, effectively ensure rigidity and the intensity of composite pipe, overcome existing stainless steel spiral welded pipe cost higher and adopt the plain carbon steel spiral welded pipe to have the problem of easily inhaling flat distortion.
The wall thickness of Stainless Steel Tube is 0.5mm, and the wall thickness of iron pipe is 3mm, and the wall thickness of vinyl tube is 0.5mm, and being suitable for diameter is the composite pipe use of 1.2m, and rigidity is higher.
The wall thickness of Stainless Steel Tube is 0.5mm, and the wall thickness of iron pipe is 2mm, and the wall thickness of vinyl tube is 0.5mm, and being suitable for diameter is the composite pipe use of 0.9m, and rigidity is higher.
The utility model reasonable in design is reliable, has effectively reduced processing cost, and the rigidity of composite pipe can stop the generation that negative pressure when work inhale flat metaboly, have advantages of simple in structure, easy to process and the life-span long.
Description of drawings
Fig. 1 is structural representation of the present utility model.
In figure: 1-Stainless Steel Tube, 2-vinyl tube, 3-iron pipe, 4-stiffening rib.
Embodiment
Anticorrosive spiral reinforcing rod composite pipe, comprise Stainless Steel Tube 1 and the outer vinyl tube 2 that arranges that nexine arranges, between Stainless Steel Tube 1 and vinyl tube 2, laminating is fixed with one deck iron pipe 3, and the sidewall of Stainless Steel Tube 1, vinyl tube 2 and iron pipe 3 is along the outside extrusion spiral shape of three's axis stiffening rib 4.
The wall thickness of Stainless Steel Tube 1 is 0.5mm, and the wall thickness of iron pipe 3 is 3mm, and the wall thickness of vinyl tube 2 is 0.5mm; The wall thickness of Stainless Steel Tube 1 is 0.5mm, and the wall thickness of iron pipe 3 is 2mm, and the wall thickness of vinyl tube 2 is 0.5mm.
In specific implementation process, corrosion resistant plate and iron plate after hot-pressing thermal rolls into integral body, are scribbled the vinyl chloride plastic layer at the iron plate outer wall, then by the spiral welded pipe machining, make.
