Abstract
The utility model discloses a steel-plastic composite pipe for low-pressure water transportation, which belongs to a water transportation pipe. The structure comprises a plastic pipe body and reinforcing ribs integrated with the pipe body. Metal reinforcing belts are combined in the reinforcing ribs. The lap surface of the plastic pipe body is provided with matched strip-shaped projections and strip-shaped grooves. A reinforcing surface is annularly winded between two reinforcing ribs with the lap surface. Compared with the prior art, the steel-plastic composite pipe for low-pressure water transportation according to the utility model has the characteristics of capability for bearing internal pressure, enlarged lap surface, firm welding at the welding joint, uniform welding, improved welding strength, no water leakage or rupture at the welding joint, excellent sealing performance, corrosion resistance, oxidation resistance, prolonged service life, reduced use cost, etc. Therefore the steel-plastic composite pipe for low-pressure water transportation has excellent generalization value.
Description
Technical field
The utility model relates to a kind of conduit pipe, especially a kind of steel-plastic composite pipe for low-pressure water delivery.
Background technique
Present industrial plastic steel composite pipe is because faying surface is very level and smooth, when twining welding, the extruded stock bar of band face of weld is sideslip very easily, and it is inside and outside inhomogeneous to cause the material bar to extrude, the weld seam not prison welding, and the band faying surface is less, after twining welding, it is hydrostatic that the band face of weld bears lower inside, and faying surface is insecure, weld strength is not enough, often occur leaking or phenomenon of rupture from the weld joint, not only using to people makes troubles, and has increased maintenance cost.Fail to solve the bonding problem of seam in its winding technology, be difficult to use in the pressure water-carriage system.
The model utility content
Technical assignment of the present utility model is to provide a kind of steel-plastic composite pipe for low-pressure water delivery at above-mentioned deficiency of the prior art, and this steel-plastic composite pipe for low-pressure water delivery weld seam can bear interior pressure in conjunction with firm.
The technological scheme that its technical problem that solves the utility model adopts is: it comprise a plastic tube body and with body all-in-one-piece strengthening rib, be compounded with the metal reinforcing band in the strengthening rib, the faying surface of described plastic tube body is provided with strip bulge and the strip groove that matches, and annular is wound with enhancing face between two strengthening rib of faying surface having.
Further scheme is:
Described projection and groove are respectively one or more.
Described groove is greater than projection.
Described enhancing face is a high density polyethylene (HDPE).
The diameter of described plastic tube body is 200-3000mm.
Steel-plastic composite pipe for low-pressure water delivery of the present utility model is compared with prior art, has following outstanding beneficial effect: can bear interior pressure, increase the overlap joint area, the weld seam firm welding, welding evenly, increase weld strength, can not occur that the weld joint leaks or phenomenon of rupture, good seal performance, anticorrosive, anti-oxidant, increase working life, reduce characteristics such as user cost.

Description of reference numerals: 1, enhancing face, 2, the metal reinforcing band, 3, faying surface, 4, strengthening rib, 5, plastic tube body, 6, projection, 7, groove.
Embodiment
Explain below doing with reference to Figure of description 1,2 pairs of steel-plastic composite pipe for low-pressure water delivery of the present utility model of accompanying drawing.
Steel-plastic composite pipe for low-pressure water delivery of the present utility model, its structure comprise a plastic tube body 5 and with body all-in-one-piece strengthening rib 4, be compounded with metal reinforcing band 2 in the strengthening rib 4, be respectively arranged with the strip bulge 6 and the strip groove 7 that match on the faying surface 3 of described plastic tube body 5, during the helically-seamed welding of sheet material, projection 6 lays respectively in the corresponding groove.Described projection and groove quantity are respectively 2, also can be one or more certainly.Annular is wound with enhancing face 1 between two strengthening rib 4 of faying surface 3 having, to increase the weld strength of faying surface 1.
Described groove 7 is unlikely to extrude in groove 7 so that clamp-on material greater than projection 6, and faying surface 3 is better linked together.Described enhancing face 1 is a high density polyethylene (HDPE), by merging, enhancing face 1 and plastic tube body is combined together.The diameter of described plastic tube body 5 is 200-3000mm.
When steel-plastic composite pipe for low-pressure water delivery of the present utility model is layed in underground connection, tube end is carried out adopting the sweat soldering technology to connect after the repair welding, strengthened the limit of pressing in tubing is anti-greatly, anticorrosive, anti-oxidant.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
Claims (5)
1, steel-plastic composite pipe for low-pressure water delivery, comprise a plastic tube body and with body all-in-one-piece strengthening rib, be compounded with the metal reinforcing band in the strengthening rib, it is characterized in that: the faying surface of described plastic tube body is provided with strip bulge and the strip groove that matches, and annular is wound with enhancing face between two strengthening rib of faying surface having.
2, steel-plastic composite pipe for low-pressure water delivery according to claim 1 is characterized in that: described projection and groove are respectively one or more.
3, steel-plastic composite pipe for low-pressure water delivery according to claim 1 and 2 is characterized in that: described groove is greater than projection.
