Abstract
The invention provides a method for producing steel-plastic multi-element composite pipes, which comprises the following steps of: modifying high-density polyethylene (HDPE) or polyvinyl chloride (PVC) plastics and manufacturing plastic plate strips; manufacturing hollow reinforcing ribs of which two side edges are recessed and overlapped; welding notches of the recessed bottoms of the reinforcing ribs by using continuous welding equipment; synchronously winding the welded reinforcing ribs with the plastic plate strips to form an inner wall of a pipe; coating and rolling on the wound pipe wall; coating a fiber mesh or winding a fiber strip and rolling on the rolled pipe wall; coating and rolling on a fiber layer to form an outer wall of the pipe; cutting the pipe which is finished in the seventh step at fixed length; sealing a port of each reinforcing rib at one end of the cut pipe, and injecting prepared cement slurry into each square reinforcing rib at the other end of the pipe by using grouting equipment; and finally, vertically erecting and fixing the pipe which is injected with the cement slurry, so that the cement slurry is solidified to form a finished pipe. The invention has the advantages that: the pipe can resist internal and external pressures and prevent cracking, an expansion on heating and contraction on cooling coefficient of the pipe is reduced, and the reinforcing ribs are prevented from rusting.
Description
Technical field:
The present invention relates to the tubing production technical field, refer in particular to the production method that a kind of steel is moulded polynary composite pipe.
Background technique
To mould Dai Gang and to develop pipeline transport is two great development trend, wherein, the high performance of plastic tube, characteristics such as high-strength, lightweight, wear-resisting, anti-corrosion, inexpensive and heavy caliber have obtained using widely, because this type of tubing rigidity and temperature tolerance are poor, can't be used for fields such as oil transportation and high pressure water delivery; And that the characteristics of metal tube are mechanical strengths is better, can not be out of shape, but its shortcoming is to get rusty easily.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, the production method that provides a kind of technology is simple, cost is low steel to mould polynary composite pipe.
For achieving the above object, technological scheme provided by the present invention is: a kind of steel is moulded the production method of polynary composite pipe, and described production method includes following steps:
First step: by modified device with HDPE or PVC plastics strengthen, toughening modifying, and be made into the plastics strip;
Second step: the hollow stiffening rib that steel band is rolled into dual-side indent and mutual overlap joint by steel rolling equipment;
Third step: with of the notch welding of continuous welding equipment with recess in the stiffening rib bottom;
The 4th step: stiffening rib and plastics strip after will welding with the spiral Wiring apparatus are twined the formation inner tube wall synchronously;
The 5th step: on Wrapping formed tube wall, cover glue, roll extrusion;
The 6th step: covered fiber net or winding fiber band and roll extrusion on the tube wall of finishing the 5th step;
The 7th step: on the layer of fibers after the roll extrusion, cover glue and roll extrusion, form the pipe outer wall;
The 8th step: the tubing fixed length cutting that will finish the 7th step;
The 9th step: will cut the stiffening rib port sealing of back tubing one end, the cement slurry for preparing in advance toward the interior injection of the square stiffening rib of the tubing the other end with grouting equipment;
The tenth step: the tubing of filled with water material-mud is stood to holding up, fixing, cement slurry is solidified, be formed into product tubing.
Described stiffening rib cross section is square, trapezoidal, arc or triangle.
After overlapping mutually, described stiffening rib side extends to form fixed hook up or down.
The invention has the advantages that first: after adopting cement slurry to fill perfusion, adopt the thick steel band of 1mm to make stiffening rib, also can reach the performance of the thick stiffening rib tubing of 4mm in the market, manufacture cost reduces greatly; Second: in stiffening rib, after the slip casting, can promote the compression resistance of tubing greatly; The 3rd: welding back stiffening rib has formed an integral body, can strengthen the resistance type performance of tubing greatly; The 4th: fixed hook is divided into two concrete chambeies with the space in the stiffening rib, jail, concrete dungeon not only can be caught on, and prevents that tubing is in use loosening, and strengthens the support force of stiffening rib; The 5th: after adopting layer of fibers, the anti-interior pressure of tubing, critical external compressive resistance, the anti-performance of breaking increase greatly, and have promoted the resisting longitudinal power and the non-deformability of tubing; The the 6th: after having adopted fixed hook, make in the stiffening rib to combine, form an integral body, reduce the tubing coefficient of thermal expansion and contraction, prevent that simultaneously stiffening rib from getting rusty with concrete.

Embodiment
The invention will be further described below in conjunction with institute's drawings attached, and preferred embodiment of the present invention is: the production method that the described steel of present embodiment is moulded polynary composite pipe includes following steps:
First step: by modified device with HDPE or PVC plastics strengthen, toughening modifying, and be made into plastics strip 1;
Second step: the hollow stiffening rib 2 that steel band is rolled into dual-side indent and mutual overlap joint by steel rolling equipment; And extend upward after the stiffening rib side overlaps mutually and form fixed hook 3.The cross section of stiffening rib can be square, trapezoidal, arc or triangle; Can also be designed to other geometrical shape as required.Fixed hook 3 is used for fixing the cement slurry after solidifying.
Third step:, make stiffening rib form an integral body with of the notch welding of continuous welding equipment with recess in the stiffening rib bottom;
The 4th step: stiffening rib and plastics strip after will welding with the spiral Wiring apparatus are twined the formation inner tube wall synchronously;
The 5th step: on Wrapping formed tube wall, cover glue, roll extrusion;
The 6th step: covered fiber net or winding fiber band and roll extrusion on the tube wall of finishing the 5th step are close on the tube wall fleece or fiber band;
The 7th step: on the layer of fibers after the roll extrusion, cover glue and roll extrusion, form the pipe outer wall;
The 8th step: the tubing fixed length cutting that will finish the 7th step;
The 9th step: the stiffening rib port sealing that will cut back tubing one end, in the square stiffening rib of the tubing the other end, inject the cement slurry for preparing in advance with grouting equipment, cement slurry can be concrete commonly used in the market, also can adopt the special concrete perfusion according to the market demand;
The tenth step: the tubing of filled with water material-mud is upright to holding up, fixing, prevent that cement slurry from solidifying the back slump; Through 10 ~ 15 days time, cement slurry is solidified again, be formed into product tubing, can the entrucking transportation.
