Said plastic inner pipe, said plastic outer tube are fixedly connected through adhesive layer respectively with between the said Steel Skeleton.
Said connection steel wire adopts flat wire.
The beneficial effect of the utility model is:
1, because the Steel Skeleton in the utility model comprises that twining the first helical steel ring and the dextrad that extend into through the flat wire left-hand respectively twines the second helical steel ring that extends into; Said first helical steel ring and the said second helical steel ring are nested; And be space crossed between the steel wire of the steel wire of the first helical steel ring and the second helical steel ring, be welded with some axially extended connection steel wires between the first helical steel ring and the second helical steel ring, changed the stirrup structure that Steel Skeleton adopts a spiral to twine in the existing technology; Steel Skeleton is not yielding bearing under the big dynamic load situation; Be not easy displacement between each steel wire, thereby increased the rigidity and the stability of Steel Skeleton, plastic inner pipe and the plastic outer tube mesh through Steel Skeleton combines and is integral simultaneously; Make plastic inner pipe and plastic outer tube can be more firmly with more stable being fixed on the Steel Skeleton; Can prevent to produce delamination between plastic inner pipe and the plastic outer tube, guarantee not corrosion of Steel Skeleton, increase the service life.
2, because Steel Skeleton is a TRS, axial, hoop that it bears are more than 30 times of plastics, and it is few to consume plastics, the tube wall thickness, and in light weight, cost is low.
3, the utility model is provided with joint socket, and construction adopts the socket joint rubber seal to be tightly connected, and easy for installation, engineering cost is low.
4, since the first helical steel ring, the second helical steel ring with is connected between the steel wire several triangle mesh of formation jointly, the mesh of triangle can further increase the structural strength of Steel Skeleton.
5, because the helix angle of the first helical steel ring is α, 60 °≤α≤65 °; The helix angle of the second helical steel ring is β; 60 °≤β≤65 °, make that the radial strength of composite metal plastic pipe is 1/2 of an axial strength, make the intensity of composite metal plastic pipe not occur superfluous at axial direction; Under the prerequisite that guarantees the composite metal plastic pipe bulk strength, reduced fabricating cost.
