Description
Technical field:
What the present invention relates to is a kind of method and device thereof of making spiral wound steel wire reinforced composite plastic pipe of inflating.
Background technology:
In plastic pipe, increase winding steel wire in recent years strengthening the existing report of tubing intensity and to use, disclose as CN2313137Y that a kind of usefulness is metal knitted to reticulate, be combined into multiple tube with interior pipe and outer tube.CN2202838Y discloses the multiple tube that accompanies the layer of metal mesh grid between a kind of tube wall layer and the outer wall layer equally, and that CN2142168Y discloses is a kind of at the multiple tube that scribbles adhesive layer at least between one deck winding steel wire layer and plastic core pipe and the outer layer plastic, and CN2466468Y discloses and a kind ofly has been wound in that compound outer back forms multiple tube on the core pipe applying earlier a layer binder and protective layer on the winding steel wire again, CN2465937Y discloses a kind of device of making metal wire combined reinforced plastics pipe, this device the core pipe extrude and outer extruder between be provided with wrapping machine and to being wound with the heating unit that core pipe wiry heats, above example is escaped by luck common weak point, because of the core pipe and the multifibres on twining need heat can be better compound with outer layer plastic, but what have in the technique scheme does not have a heater, though the heater that the core pipe that pair winding steel wire is arranged that has heats, but the core pipe twines tension force and middle level at steel wire, outward layer by layer in the composite molding chamber under the effect of molten mass pressure shape and size alter a great deal, core pipe diameter diminishes and collapses flat, can't guarantee core pipe and steel wire, outer tube is closely compound to be an integral body, cause and peel off delamination each other, core pipe internal surface quality is also very poor simultaneously; Core pipe and steel wire and outer compound tense are to carry out under the heating situation in addition, because the support to tube wall of expansive force in not having, cooling has had trend and the phenomenon that breaks away from steel wire floor, external composite layer and inwardly shrink, peel off with steel wire and outer generation when shrinking at tubing cooling and shaping process core pipe.Moreover be more than tens hours the stabilization time of cooling and shaping at least, support force effect in the cooling and shaping process, not having, even inside and outsidely basically when producing compoundly be one, this kind multiple tube is also very easy delamination in the cooling and shaping process.The compound pipeline complex pipeline that said method is produced, in long-term the use because of expanding with heat and contract with cold and the pressure oscillation factor more can cause composite bed and steel wire to peel off delamination each other, space between formation, pipeline discharge pressure medium can permeate from the space because of core pipe or the local damage of pipe end face and cause the pipe-line system broken invalid, also can reduce pipeline bearing capacity and service life because of composite layered.
Summary of the invention:
