Abstract
The invention discloses a steel-plastic composite pipe. The steel-plastic composite pipe comprises a steel strip (4) with a specially-shaped cross section and plastic coatings (2), and is characterized in that: the specially-shaped cross section of the steel strip is hollow and closed; the steel strip is spirally wound to form a tubular body (1); adjacent edges of the steel strip are fixedly welded; and both inner layer and outer layer of the tubular body are provided with the plastic coatings. Since the specially-shaped steel strip has a hollow and closed structure and is wound and welded to form the tubular body, the ring stiffness of a pipeline is obviously improved, high-strength pressure can be born, the pipe is difficultly degummed and squeezed to be broken, and the aims of high strength, high pressure bearing capacity, firm steel-plastic adhesion, difficulty in separating steel from plastic and continuous integral steel strips are fulfilled.
Description
Technical field
The present invention relates to a kind of tubing, relate in particular to a kind of steel-plastic composite pipe.
Background technique
Polyethylene drainage bellows and entwining tube have excellent performance, but its ring stiffness is low, have limited the degree of depth and the bearing load that bury ground.In order to obtain the waste pipe of high ring rigidity, adopted the method for various enhancings both at home and abroad, made steel band reinforced polyethylene spiral ripple pipe.Technology is substantially: coating viscose resin on steel, and Steel Rolling is become the cross section is " ∩ " profiled strip, be spirally wound on again on the internal layer that high density polyethylene (HDPE) makes, apply one deck high-density polyethylene resin then on the surface of steel band, the slit between steel band is filled with high-density polyethylene resin and is made steel band reinforced polyethylene spiral ripple pipe.The enhancing composite pipe that makes has like this been obtained remarkable effect at each aspect of performance, but because its steel band is " ∩ " type, and the steel band gap is filled by high-density polyethylene resin, cause pipe structure intensity extremely unbalanced, peel off phenomenons such as fracture, and can not bear interior pressure at limited, the easy layering of coming unstuck of bearing capacity, steel band trough place.
Summary of the invention
The objective of the invention is to provide in order to overcome the deficiencies in the prior art a kind of high strength, high pressure-bearing, steel mould bonding firmly, steel mould be difficult for breaking away from, steel band is whole steel-plastic composite pipe continuously.Its concrete technological scheme is: steel-plastic composite pipe comprises that section is special-shaped steel band and plastic coating, the special-shaped section of steel band is the hollow enclosed type, be wound in tubular body through spiral again, the neighboring edge of steel band is affixed to weld, and the internal and external layer of tubular body is equipped with plastic coating.
Said steel band special-shaped section is the hollow enclosed type, and it is the plane simultaneously, and another side is to outer lug.
In order to guarantee that plastic coating combines with steel band closely, has additional the adhering resin layer between steel band and the plastic coating.
In order to prevent the hollow internal corrosion of steel band, also be provided with adhering resin layer and plastic coating on the surface, inside of hollow steel band.
From technological scheme of the present invention as can be seen, because profiled strip has adopted the hollow closed structure, and is welded into tubular body by winding, has significantly improved the ring stiffness of pipeline, can bear high-intensity external pressure, be difficult for coming unstuck, squeeze and break, fracture, and can bear interior pressure, reached high strength of the present invention, high pressure-bearing, steel fully and moulded that bonding firmly steel is moulded and is difficult for breaking away from, steel band be the goal of the invention of integral body continuously.
