Definitions

  • This invention relates generally to a steel-plastic composite pipe component, and specifically to a wire-mesh reinforcement-plastic composite pipe component and method for making the same.
  • Plastic pipes have been widely used in many fields due to good corrosion resistance, light weight and convenience of installation. However, applications in the industrial field are limited because of lower mechanical strength, lower rigidity and decreased heat-resistance over standard metal pipes. There are numerous configurations of pipe and methods of manufacturing same found in the prior art that have been designed to provide increased mechanical strength, increased rigidity, and greater heat-resistance over plastic pipes.
  • U.S. Patent No. 3,526,692 to Onaka describes a mechanism for continuously coiling wire into a helix and feeding the helix axially through a plastic extruding die where a plastic pipe body is extruded so that the wire helix is embedded in but projects from the outer surface of the pipe body. The pipe body is then passed through a second plastic extruding die in which a tubular plastic layer is bonded to the outer surface of the pipe body.
  • U.S. Patent No. 4,258,755 to Higbee describes a flexible reinforced cured resin hose including a combination of helically wound cable wires and body wires embedded therein. Two plies of wires are wrapped in opposite directions around the periphery of a liner tube supported on a mandrel, the plies being supported in a resin filler layer applied over the liner to hold the wires spaced apart.
  • the pipe described in China Patent 94104509 has distinct advantages over plastic pipes and over other steel-plastic composite pipes known to those skilled in the art, including increased mechanical strength, increased rigidity, and a greater heat resistance.
  • the steel skeleton according to that patent is constructed by both longitudinal and traverse reinforcing wires, and the amount of both longitudinal reinforcing wires and traverse reinforcing wires in the steel skeleton are 50% respectively.
  • the diameter of the transverse reinforcing wire is increased. This results in increasing the wall thickness of the composite pipe.
  • Another object of the invention is to provide a composite pipe that has a low hydraulic loss.
  • Yet another object of the invention is to provide a highly efficient and low cost method for making a composite pipe.
  • the pipe has a wiremesh reinforcement-plastic composite construction that includes a first and second spiral reinforcing wire layer.
  • the first spiral reinforcing layer has grooves formed at selected intervals, and the second spiral reinforcing wire layer is pressed into the grooves.
  • the first and second spiral reinforcing wire layers are deformed and joined together by pressure to form a wiremesh reinforcement.
  • the two spiral reinforcing wire layers have a left and right spiral angle ⁇ l and ⁇ 2 respectively relative to the central line, the left and right spiral angles ⁇ l and ⁇ 2 can change in the range of 0° to 90°.
  • Thermoplastic penetrates the wiremesh reinforcement and fills both sides of the wiremesh reinforcement to form the composite pipe or component.
  • FIG. 1 is a partial cross-sectional side view of the device for making composite straight pipe of the invention in general;
  • FIG. 2 is a sectional view taken along line A-A of Fig. 1 ;
  • FIG. 3 is a side plan view of the electric-fusion coupler of the invention.
  • FIG. 4 is a side plan view of the flange coupler of the invention.

  • a plurality of threaded rods 8 are mounted on the main shaft 7.
  • a first spiral reinforcing wire 2 is pulled from a first winding roll 1 and wound onto a disk follower 4, which includes one or preferably a plurality of first winding rollers 3.
  • the first winding rollers 3 are arranged outside the main shaft 7 for winding the first spiral reinforcing wire layer 2 onto the main shaft 7.
  • a cut roller 10 is used to cut a plurality of spaced grooves (not shown) in the transversal section of the first spiral reinforcing wire layer 2a. The grooves are placed at intervals, the intervals are determined by the specific materials that are used for the wire.
  • the rotation rate of the winding roller 3 is n3
  • the rotation rate of the main shaft 7 is nl
  • the relationship between the rates of rotations is n3>nl.
  • a second reinforcing wire 5 is pulled from a second winding roll 6 and wound onto one or a plurality of second winding rollers 11. Following the rotation of the main shaft 7, the second reinforcing wire layer 5 is wound onto the first spiral reinforcing wire layer 2 with a spiral angle ⁇ 2 in opposite direction to the angle ⁇ l of the first spiral reinforcing wire layer 2a. This forms the second spiral reinforcing wire layer 5 a, which is pressed by a second winding roller 1 1 into the grooves formed on the first spiral reinforcing layer.
  • both of the spiral reinforcing wire layers are deformed under pressure and are joined together in the grooves to form a wiremesh reinforcement 23.

Abstract

Tuyau à structure composite en plastique avec treillis métallique de renforcement, qui possède des première et seconde couches de fil métallique de renforcement en spirale. La première couche de renforcement en spirale possède des rainures formées à des intervalles choisis et la seconde couche de fil métallique de renforcement en spirale est comprimée dans les rainures. Les première et seconde couches de fil métallique de renforcement en spirale sont déformées et jointes ensemble par compression pour former un treillis métallique de renforcement. Les deux couches métalliques de renforcement en spirale possèdent des angles de spirale gauche et droit α1 et α2 respectivement par rapport à la ligne centrale et lesdits angles α1 et α2 peuvent varier dans la plage de 0° à 90°. Le thermoplastique pénètre dans le renforcement sous forme de treillis métallique et remplit les deux côtés dudit treillis pour former le tuyau composite.
