Abstract
The invention discloses a polyethylene pipe and belongs to a chemical building material. The polyethylene pipe comprises a pipe wall, interfaces at two ends, a spirally-arranged hollow rib, and metal reinforcing ribs which are spirally wound along an axis direction of the hollow rib. The technical defects that the hollow rib has high thermal deformation and the pipe has low ring stiffness in the polyethylene pipe in the prior art are overcome. The polyethylene pipe is mainly used for a drainage pipe in municipal engineering.
Description
Technical field
The invention belongs to tubing, relate in particular to the water drainage plastics pipe that uses in a kind of municipal engineering.
Background technique
At present, the polyvinyl piping materials that adopts in the municipal engineering because the hollow rib temperature distortion is big, thereby causes the polyvinyl piping materials ring stiffness low; For the bigger hollow rib of diameter even can't be Wrapping formed, to such an extent as to cause the waste of material, cost strengthens, and therefore, can not satisfy the needs of engineering.
Summary of the invention
In order to overcome the above-mentioned defective that exists in the existing technology, the invention provides a kind of polyvinyl piping materials.
Polyvinyl piping materials of the present invention is to adopt following technological scheme to realize: a kind of polyvinyl piping materials comprises the hollow rib of tube wall, two end interfaces, helical arrangement being provided with the metal reinforcing that twines along hollow rib axial direction spirality in the said hollow rib.
The cross section of said metal reinforcing is circular or square, and said hollow rib is one deck or more than one deck.
Compared with prior art; The beneficial effect of polyvinyl piping materials of the present invention is: owing in hollow rib, adopted the metal reinforcing support; Reduced the distortion that hollow rib causes because of being heated; Thereby make the ring stiffness of polyvinyl piping materials improve greatly,, can save wide variety of materials for reaching the polyvinyl piping materials of equal ring stiffness.The present invention also can use other polyolefine materials to make.
Description of drawings
Fig. 1 is the structural representation of hollow rib vertical profile.
Fig. 2 is the cross-sectional structural representation of hollow rib.
Embodiment
Below in conjunction with accompanying drawing polyvinyl piping materials of the present invention is described further:
Embodiment 1, a kind of polyvinyl piping materials; The hollow rib 2 that comprises tube wall 1, two end interfaces, helical arrangement; Be provided with the metal reinforcing 3 that twines along hollow rib axial direction spirality in the said hollow rib, the cross section of said metal reinforcing 3 is circular, and said hollow rib is one deck.
Embodiment 2, a kind of polyvinyl piping materials; The hollow rib 2 that comprises tube wall 1, two end interfaces, helical arrangement; Be provided with the metal reinforcing 3 that twines along hollow rib axial direction spirality in the said hollow rib, the cross section of said metal reinforcing 3 is square, and said hollow rib is two-layer.
Claims (3)
1. polyvinyl piping materials comprises it is characterized in that the hollow rib of tube wall, two end interfaces, helical arrangement: be provided with the metal reinforcing that twines along hollow rib axial direction spiral in the said hollow rib.
2. polyvinyl piping materials according to claim 1 is characterized in that: the cross section of said metal reinforcing is for circular or square.
3. polyvinyl piping materials according to claim 1 and 2 is characterized in that: said hollow rib is one deck or more than one deck.
