Abstract
The composite silane-crosslinked polyethylene pipe is featured by that it includes one inner silane-crosslinked polyethylene layer, one spiral wound steel wire structure layer formed by steel wire coated by adhesive or the mixture of adhesive and polymer on the outside wall of the inner layer, one outer composite thermoplastic plastic layer outside the wound layer, and one heat insulating foamable layer outside the outer layer. The composite pipe of the present invention is pressure resistant, heat insulated, fireproof, antifreezing, low in cost and practical and is especially suitable for use in engineering of relatively high pressure and in very cold area.
Description
Technical field:
What the present invention relates to is a kind of composite pipe, particularly be a kind ofly to adopt heat fusing to connect or the composite silane cross-linked polyethylene pipe that insulating foam layer and spiral wound steel wire are arranged of bonding connection.
Background technique:
Spiral wound steel wire crosslinked polyethylene composite pipe has improved a grade with the bearing capacity of polyethylene pipe, composite silane cross-linked polyethylene pipe, make this pipe not only keep all premium properties of silane crosslinked polyethylene pipes, and because of spiral wound steel wire on it, and Steel Wire Surface is coated with binder or binder and blend polymer construction layer, steel wire and organosilane crosslinked polyethylene and thermoplastic are compound to be one, and the intensity of the composite material of real meaning has been arranged.Thereby enlarged the application of plastic tube on middle pressure grade engineering, enlarged the application of plastic tube.But at severe cold areas, under the service condition of subzero tens degree, can reduce pipeline wall thickness, also reduce pipeline wall thickness simultaneously, make the insulating power of this pipe not reach engine request in order to save silane crosslinked polyethylene because of adopting steel wire to twine to gain in strength.If it is increase wall thickness, then uneconomical.If adopt foaming layer to increase insulating power the effect of getting twice the result with half the effort is arranged then.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, a kind of good pressure-resistant performance is provided, certain flexibility is arranged, insulation, fire-retardant, adiabatic, antifreeze and economical and practical adopted heat fusing connects or the composite silane cross-linked polyethylene pipe of bonding connection.
The object of the present invention is achieved like this:
Composite pipe of the present invention comprises the organosilane crosslinked polyethylene internal layer, spiral is wound with by the formed spiral wound steel wire construction layer of steel wire of binder or binder and blend polymer coating on inner layer outer wall, extrude on the outer wall of spiral wound steel wire construction layer that the composite thermoplastic plastics are formed to be the skin of one with internal layer, spiral wound steel wire construction layer are compound, be compounded with one deck insulating foam layer in outer periphery.
Above-mentioned outer thermoplastic layer is the blend or the polyolefin polymer nano grade polymer of polyolefin polymer or polyolefin polymer and inorganic matter, or PVC or chlorinated polynvinyl chloride (CPVC) or the blend of the blend of PVC and inorganic matter or chlorinated polynvinyl chloride (CPVC) and inorganic matter or polyvinyl chloride nano level polymer or chlorinated polynvinyl chloride (CPVC) nano grade polymer.
Above-mentioned spiral wound steel wire construction layer is to be entwined by the mode spiral that at least one steel wire is left-handed or is dextrorotation, or being mode cross-helicity left-handed and that at least one steel wire is dextrorotation by at least one steel wire is entwined.
Above-mentioned insulating foam layer is that the blend material of fire-retardant polyolefin polymer or itself and inorganic matter is made, or the blend material of the PVC of flame retarding or flame retardancy or chlorinated polynvinyl chloride (CPVC) or they and inorganic matter is made, or the inorganic material of flame retardancy or adiabaticity makes, and the outermost surface of insulating foam layer has the close layer of one deck matter.
Good pressure-resistant performance of the present invention, certain flexibility, insulation, fire-retardant, adiabatic, antifreeze and economical and practical are arranged, press the severe cold areas of grade engineering or subzero tens degree in being specially adapted to.
