Abstract
The utility model relates to a kind of steel-plastic composite pipe, and its structure comprises steel tube body and anticorrosive coat, and described steel tube body is wound around joint by ribbon spiral and forms, and it is characterized in that, is shaped with the projection parallel with ribbon spiral winding direction on described steel tube body surface; The shape of cross section of described projection is circular arc.The utility model is provided with spiral arc-shaped convex in steel tube body, and the ring stiffness of steel-plastic composite pipe is significantly improved.Not only can bear high in pressure, the external pressure of high strength can also be born, not yielding, rack, rupture, applied widely, long service life.
Description
Technical field
The utility model relates to a kind of engineering tubing, specifically a kind of steel-plastic composite pipe.
Background technique
The body of existing spiral steel-plastic composite pipe is wound around joint by ribbon spiral to form, and fastens and get final product closely knit connection through rolling again, then apply anticorrosive coat outward in steel tube body after the Edge of Steel Strip turnover of seam crossing.The steel pipe raw materials of this structure is single, the diameter of product and length can adjust arbitrarily as required, connected structure between steel band, makes the joint strength of steel tube body higher than the weld strength of common steel tube joint, multiplexly makes the engineering such as cable trunk, sewage pipe tubing.But by the restriction of the conditions such as the buried degree of depth, load, the ring stiffness of the steel pipe of this structure still is apparent not enough, and bearing capacity is limited, the phenomenon such as easily deform.
Model utility content
The purpose of this utility model is just to provide a kind of steel-plastic composite pipe, to solve the defect of existing pipe ring insufficient rigidity.
The purpose of this utility model is achieved in that a kind of steel-plastic composite pipe, comprises steel tube body and anticorrosive coat, and described steel tube body is wound around joint by ribbon spiral and forms, and it is characterized in that, is shaped with the projection parallel with ribbon spiral winding direction on described steel tube body surface; The shape of cross section of described projection is circular arc.
The width of described protruding bottom accounts for 1/3 of described width of steel band.
The height of described projection is 13mm; The width of described protruding bottom is 30mm.
Described projection is positioned at the middle part of described steel band.
The utility model is provided with spiral arc-shaped convex in steel tube body, and the ring stiffness of steel-plastic composite pipe is significantly improved.Not only can bear high in pressure, the external pressure of high strength can also be born, not yielding, rack, rupture, applied widely, long service life.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, steel tube body, 2, protruding, 3, seam.
Embodiment
As shown in Figure 1, steel tube body 1 is wound around by ribbon spiral to make.The middle part of the steel band that the utility model uses longitudinally is processed with arc-shaped convex, and the both wings edge of steel band is processed as turnover structure.Seam 3 is made through rolling for steel band turns down part snap-fit again, can closely knitly connect.
The surface of the steel tube body after volume circle forms spiral protruding 2, and the shape of cross section of protruding 2 is circular arc.
Anticorrosive coat (not shown) outside steel tube body routinely technology applies.
The steel-plastic composite pipe of the utility model design, raw materials is single, and the diameter of product and length can adjust arbitrarily as required.The utility model can be used as the engineering such as fulgurite, sewage pipe tubing.
Claims (2)
1. a steel-plastic composite pipe, comprises steel tube body and anticorrosive coat, and described steel tube body is wound around joint by ribbon spiral and forms, and it is characterized in that, is shaped with the projection parallel with ribbon spiral winding direction on described steel tube body surface; The shape of cross section of described projection is circular arc; Described projection is positioned at the middle part of described steel band; The width of described protruding bottom accounts for 1/3 of described width of steel band; The both wings edge of described steel band is processed as turnover structure; The seam crossing of described steel tube body is that the turnover part snap-fit of described steel band is made through rolling again.
2. steel-plastic composite pipe according to claim 1, is characterized in that, the width of described protruding bottom is 30mm, and the height of described projection is 13mm.
