Abstract
The utility model particularly relates to an anti-corrosion convex-concave spiral reinforcing rib composite pipe and solves the problems that carrying, installation and production of existing steel pipes are time-wasting, labor-wasting and costly. The anti-corrosion convex-concave spiral reinforcing rib composite pipe comprises an iron pipe, wherein the iron pipe is provided with a plurality of spiral reinforcing ribs; each spiral reinforcing rib is composed of a plurality of convex blocks which are distributed at equal intervals and formed by extruding outwards from the inner surface of the iron pipe; the inner surface and the outer surface of the iron pipe are provided with plastic coatings. The anti-corrosion convex-concave spiral reinforcing rib composite pipe is reasonable and reliable in structural design, and the cost of the composite pipe is efficiently reduced while the rigidity of the composite pipe is ensured; moreover, the anti-corrosion and antirust performance can be effectively improved, and good ventilation effect of the composite pipe is ensured at the same time; the anti-corrosion convex-concave spiral reinforcing rib composite pipe has the advantages of simple structure and convenient processing.
Description
Technical field
The utility model relates to composite pipe, is specially a kind of corrosion protection convex-concave shape spiral reinforcing rod composite pipe.
Background technique
At present, domestic existing steel spiral welded pipe, the fluid delivery tube of existing oil and gas industry standard SY/T5036-2000, SY/T5037-2000, SY/T5038-2000, SY/T5039-2000 series.Plastic-coated, soak plastic steel pipe and mostly be weldless tube and straight-seam pipes, but existing steel pipe is only applicable to positive airway pressure, fluid is carried, when for subnormal ambient, the wall thickness of this steel pipe is thinner, is easy to be inhaled flat distortion, causes using.
While working under subnormal ambient in order meeting, to need thickened steel-tube wall degree, to cause like this cost of production of steel pipe to increase the weight of, and carrying, install, produce and waste time and energy, affect operating efficiency.
Summary of the invention
There is carrying in order to solve existing steel pipe in the utility model, waste time and energy when installing, producing and problem that cost is higher, and a kind of corrosion protection convex-concave shape spiral reinforcing rod composite pipe is provided.
The utility model is to adopt following technological scheme to realize: corrosion protection convex-concave shape spiral reinforcing rod composite pipe, comprise iron pipe, on iron pipe, be provided with some spiral reinforcing rods, every stiffening rib is equally spaced by several and forms from the iron pipe internal surface protruding block that outwards extruding forms, and internal surface and the outer surface of iron pipe are provided with coating layer.
By coating layer is set, composite pipe is played to anticorrosion, rust inhibition, effectively alleviated the weight of composite pipe simultaneously, overcome existing steel pipe and had carrying, waste time and energy when installing, producing and problem that cost is higher.
Between coating layer and iron pipe, be provided with the transition glue-line boning with both, by transition glue-line is set, improved the soundness of coating layer and iron pipe bonding.
The coating layer of iron pipe internal surface is rubber layer, and the internal surface of rubber layer is column structure, and composite pipe ventilatory effect further gets a promotion.
The coating layer of iron pipe internal surface replaces with Stainless Steel Tube, and stiffening rib is equally spaced and formed from the stainless steel pipe inner surface protruding blocks that outwards extruding forms by some, has further promoted the rigidity of composite pipe.
The cross section of protruding block is circle or rectangle.
The utility model reasonable in design is reliable, when guaranteeing composite pipe rigidity, effectively reduced the cost of composite pipe, and anticorrosion, rustless property is promoted effectively, guaranteed the ventilatory effect that composite pipe is good simultaneously, had advantages of simple in structure, easy to process.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-iron pipe, 2-protruding block, 3-coating layer.
