Problems solved by technology

What's more, when the steel skeleton is introduced as a reinforcement, the skeleton plays a layered shielding effect on the continuum, so that the effect of the high elastic expansion performance of the polymer in this type of pipe is greatly attenuated, how to solve the problem of the inner peripheral wall of the pipe fitting socket Experiment, research, design and manufacture of the length of the heating wire arranged in a spiral ring and the length of the joint welding of the pipe, and the influence of the steel skeleton in the pipe body and the influence of the length change in the length, as well as the internal bearing pressure and its relationship in the liquid medium test

Embodiment 1

[0032] figure 1 A schematic structural diagram 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 frame 2 compounded therewith, and on the surface of the steel frame 2, there is a composite layer 3 for protecting the steel frame. The sockets 4 at both ends of the pipe body are respectively circumferentially arranged with spiral ring-shaped electric heating wires 5, and are installed on the positive and negative terminals 6, 7 on the outer wall of the pipe body. The relative distance L of the axial port of the steel skeleton relative to the heating wire from the first circle of the socket end is the axial distance S of the heating wire 1 80% of. The opening area of ​​the part of the steel skeleton where the projection of the steel skeleton on the axis of the pipe body coincides with the projection of the electric heating wire on the axis is 40% of the expanded area of ​​this part of t...

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 9 compounded therein in the two-way polymer continuous pipe body 8 . There is a polymer material layer 11 different from the material of the pipe body on the inner wall of the socket 10 at both ends of the pipe body. There are spiral ring-shaped electric heating wires 12 arranged circumferentially on the polymer material layer of the socket. Negative terminal 13,14. The relative distance L of the axial port of the steel skeleton from the first circle of the socket to the heating wire 2 is the axial distance S of the heating wire 2 130%. Electric heating wire 12 such as image 3 It is shown that its outer periphery is coated with an adhesive layer 15 .

Abstract

This invention provides a perforated steel framework reinforced composite polymer pipe joint including polymer continuous pipe and perforated steel framework for strengthening intensity similar to the shape of the pipe compounded with the pipe having bell socket at least one end connecting the pipe, the internal wall of the bell socket is distributed with screw loop electric heater in girwth withbinding post on the pipe radially or axially characterizing that the steel framework axial part relative to the screw loop electric heater allocated in girth inside of the pipe bell socket, the relative Length L from the socket end first loop is 25%-130% of the axial length S of the distributed electric heater.

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...
