Problems solved by technology

What's more, when the steel skeleton is introduced as a reinforcement, the skeleton acts as a layered screen for the continuum, so that the high-elastic expansion performance of the polymer is greatly attenuated in this type of pipe, and how to solve the problem in the pipe fitting socket. The skeleton design problem of the overlapping part of the spiral ring heating wire arranged on the surrounding wall and the skeleton of the pipe fitting

Embodiment 1

[0032] figure 1 A structural schematic section of Embodiment 1 of the present invention is given. In the outer wall of the two-way polymer continuous pipe body 1, there is a perforated steel skeleton 2 formed by welding composite steel plates with holes. There is a steel skeleton protection layer 3 on the outside of the steel skeleton. Spiral ring-shaped electric heating wires 5 are distributed circumferentially at 4 sockets at both ends of the pipe body, and positive and negative terminals 6 connected with the electric heating wires are installed on the outer wall of the pipe body. The overlapping part of the projection of the steel skeleton on the axis of the pipe body and the projection of the electric heating wire arranged in a spiral ring on the axis (as shown in the figure a 1 , b 1 ) steel frame opening area is 50% of the developed surface area of ​​the steel frame.

Embodiment 2

[0034] figure 2 , image 3 A schematic structural diagram of Embodiment 2 of the present invention is given. There is a perforated steel skeleton 8 compounded therein in the two-way polymer continuous pipe body 7 . The inner wall of the socket at both ends of the pipe body has a polymer material layer 9 different from the material of the pipe body, a spiral ring-shaped electric heating wire 10 distributed circumferentially on the polymer material layer, and positive and negative terminals 11 installed on the outer periphery of the pipe body . The part of the steel skeleton on the axis of the pipe body that coincides with the projection of the electric heating wire on the axis (as shown in Figure a 2 , b 2 ) opening area is 30% of the expanded area of ​​the steel skeleton. Electric heating wire 10 such as image 3 Its periphery is shown covered with an adhesive layer 12 . The steel frame used in the present embodiment can be selected the steel frame that is welded by th...

Embodiment 3

[0036] Figure 7 Figure 3 of Embodiment 3 of the present invention is given. A perforated steel framework 15 similar in shape to the three-way polymer continuous pipe body 14 is compounded. The inner wall of the socket socket is respectively provided with helically wound electric heating wires 16, 17 and connected with positive and negative poles 18, 19 respectively. The opening area of ​​the part where the upper or lower part of the steel skeleton coincides with the projection of the electric heating wire on the axis of the pipe body (a in the figure) 3 , b 3 、a 4 , b 4 ) is 95% of the expanded area of ​​the steel skeleton.

[0037] This embodiment 3 can be selected as Figure 8 Shown is an investment cast steel skeleton with unequally spaced holes and hole diameters.

[0038] Fig. 9 is a schematic diagram of a 90° elbow steel skeleton structure. The opening area at its two straight ends is between 30% and 95% of the developed area of ​​this section, and the open area...

Abstract

This invention provides a perforated steel framework reinforced composite polymer pipeline joint including a continuous pipe and a perforated steel framework similar to the pipe for strengthening intensity compounded with the tube containing a bell socket at least one end connecting with the pipe, screw loop electric heater is distributed in girth on the bell socket wall and binding post of the heater is on the pipe radially or axially characterized that the general hole area on the coincidence part of the framework projected by the framewoke on the axis and that by the screw loop electric heater on the axis is 30%-95% of the said framework spreading surface area.

Description

Technical field: [0001] The invention relates to the design, manufacture and engineering connection of steel-plastic composite pipes and pipe fittings, to the design and engineering connection of steel skeleton reinforced composite polymer pipes and pipe fittings with holes, especially to the reinforced steel skeleton with holes Manufacture, design and connection of composite polymer pipe fittings for engineering applications. Background technique: [0002] The perforated steel plate (belt) is curled into a cylindrical skeleton and welded to form a metal reinforcement in the steel-plastic composite pipe wall; and the latitudinal steel wire is wound with the warp steel wire and welded or the warp steel wire is spirally wound. Distributed and welded on the steel-plastic composite pipe wall to become the metal reinforcement in the steel-plastic composite pipe wall; and spirally wound or braided steel wire on the formed polymer pipe wall to form a cylindrical steel skeleton, and...
