Description
Technical field
The utility model relates to plastic-steel spirally-wound pipe processing technique field, specifically a kind of two flat walls I-shaped structure plastic-steel-wound pipe fitting.
Background technique
At present, plastic-steel spirally-wound pipe is made up through spiral winding welding of the heterotypic strip of steel plastic compount, its inner wall smooth is smooth, be mould Dai Gang, to mould the update product for cement, this kind of tubing has the advantages such as corrosion-resistant, quality light, simple installation, through-current capacity are large, the life-span is long, municipal drainage can be widely used in, remote low-pressure water delivery, mine and chemical industry draining, in irrigation and water conservancy irrigation, ventilation duct, sewage treatment works and other major construction projects.To the saving energy, decreasing pollution, protection of the environment is significant.Plastic-steel-wound drainage pipe band in the market through dedicated extruder, together with through specific complex mould steel band being compound to the polyethylene of melting, then through stock mould sizing, then through being cooled to heterotypic strip.Thus its wall pipe of existing plastic-steel-wound tubular construction generally includes tube wall and the stiffening rib along outer surface of tube wall helical arrangement, because its outer wall exists bellows-shaped, as shown in Figure 1, what its stiffening rib generally adopted is steel band, steel band profile is set to " ⊥ " shape skeletal structure, outer field like this high-density polyethylene layer sometimes can not complete coated stiffening rib skeletal structure, causes stiffening rib to be formed and exposes situation, will reduce product ring stiffness like this.Meanwhile, what take in transportation process due to existing tubing is means of transprotation with large pipe box tubule, thus in transportation process, very easily damages layer structure.Because existence is exposed because the coated inequality of steel band or tubing transportation loading and unloading damage the steel band caused, occur the situation of getting rusty, then ring stiffness lost efficacy, and then affected quality of product, thus caused user to bring totally unfavorable impact to normal such product that uses.
Model utility content
The technical problems to be solved in the utility model is for Problems existing in background technique, provides a kind of two flat walls I-shaped structure plastic-steel-wound pipe fitting.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of two flat walls I-shaped structure plastic-steel-wound pipe fitting, comprise inner wall layer and outer wall layer, described inner wall layer comprises high density polyethylene (HDPE) composite bed and the steel structure be coated in high density polyethylene (HDPE) composite bed and inwall weld seam, described outer wall layer comprises outer planomural layer and the steel structure be coated in planomural layer and outer wall weld seam, described outer planomural layer is also provided with welding scrap (bridge), and the inwall weld seam be arranged in inner wall layer is connected by welding scrap (bridge) with the outer wall weld seam be arranged in outer planomural layer.
Further, described inwall weld seam and outer wall weld seam are connected to form closed space by welding scrap (bridge).
Adopt a kind of two flat walls I-shaped structure plastic-steel spirally-wound pipe of the present utility model, compared with prior art, its advantage is:
1, after adding planomural of going out, can reduce in existing production process the step needing to carry out by artificial means manger board operation, outer planomural is then that mechanical braking is produced, and effectively lowers the use in personnel and place in production process.
2, due to outermost surface be set to planomural structure can solve the tubing of tubing different size in transportation process can in the same time and place can not the transportation problem of sleeve pipe.
3, the interpolation of outer planomural can better carry out the variation of tubing in connection procedure, and can realize the direct welding of tubing.
4, this structure effectively raises the seam tensile strength of tubing, thus it is lower to solve drawing pipe intensity, easily occurs the problem of disconnected pipe.
5, tubing steel structure is better fixed by outer planomural, original " ⊥ " structure is had to become " work " word structure, effectively control the tubing phenomenon of falling muscle, ensure that the optimization of ring stiffness, decrease simultaneously and lost efficacy because the coated inequality of steel band or tubing transportation loading and unloading damage the naked plain ring stiffness that gets rusty of the steel band caused.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of existing plastic-steel-wound pipe fitting;
Fig. 2 is structural representation of the present utility model.
Shown in figure: the outer planomural layer of 1-inner wall layer, 2-outer wall layer, 3-composite bed, 4-steel structure, 5-inwall weld seam, 6-, 7-outer wall weld seam, 8-weld scrap (bridge), 9-closed space.
Embodiment
As shown in Figure 2, a kind of two flat walls I-shaped structure plastic-steel-wound pipe fitting of the present utility model, comprise inner wall layer 1 and outer wall layer 2, described inner wall layer 1 comprises high density polyethylene (HDPE) composite bed 3 and the steel structure 4 be coated in high density polyethylene (HDPE) composite bed 3 and inwall weld seam 5, described outer wall layer 2 comprises outer planomural layer 6 and the steel structure 4 be coated in planomural layer 6 and outer wall weld seam 7, described outer planomural layer 6 is also provided with welding scrap (bridge) 8, and the inwall weld seam 5 be arranged in inner wall layer 1 is connected by welding scrap (bridge) 8 with the outer wall weld seam 7 be arranged in outer planomural layer 6.
Further, described inwall weld seam 5 and outer wall weld seam 7 are connected to form closed space 9 by welding scrap (bridge) 8.
In actual processing and making process, outer wall layer 2 simultaneously, is bonded in one-body molded formation two flat walls I-shaped structure of the present invention plastic-steel-wound pipe fitting in inner wall layer 1 by special device by adopt extruder co-extrusion to be coated with inner wall layer 1 that steel structure 4 in high density polyethylene (HDPE) composite bed 3 and inwall weld seam 5 form.By existing " ⊥ " structure is become " work " word structure, effectively can control tubing and occur the phenomenon of falling muscle in preparation process, thus ensure that the optimization of ring stiffness, decrease simultaneously and lost efficacy because the coated inequality of steel band or tubing transportation loading and unloading damage the naked plain ring stiffness that gets rusty of the steel band caused.
