Abstract
The utility model discloses a plastic composite tube internally clamped with a stainless steel pressure bearing layer. The plastic composite tube is characterized by consisting of a plastic inner layer tube, the stainless steel pressure bearing layer and a plastic outer covering layer which are compounded with one another from inside to outside. The tube wall of the plastic composite tube provided by the utility model is thin, and the weight of the plastic composite tube is light; various pressure bearing capacities and various using temperatures can be also realized according to demands; the plastic composite tube is applied to pipelines resistant to high heat and high pressure, is also light in weight and is reliably connected and can effectively replace pressure bearing metal tubes such as copper tubes and stainless steel tubes.
Description
Technical field
The utility model relates to a kind of plastic composite pipe of inner clip stainless steel bearing course, belongs to the composite pipe technical field.
Background technique
Traditional composite metal-plastic pipe more adopts internal plastic coating or lining to mould and cover outward and moulds, and such composite pipe is installed connection just take the metal layer function as main at metal layer, and plastic layer is only born various protective actions; And adopt outer cover plastic layer install connect composite pipe, the flexible delamination of expansion of failing again to stop metal and plastics junction separates.
Summary of the invention
Problem to be solved in the utility model is high temperature resistant and high pressure and the lighter composite pipe of weight that can effectively keep the metallic intermediate layer pipe.
In order to address the above problem, the utility model provides a kind of plastic composite pipe of inner clip stainless steel bearing course, it is characterized in that, described plastic composite pipe is comprised of from inside to outside compound inner plastic pipe, stainless steel bearing course, plastics outer covering layer.
Preferably, described stainless steel bearing course forms by being wound in the outer stainless steel of inner plastic pipe.
Inner plastic pipe in the utility model and plastics outer covering layer adopt thermoplastic, and the plastics outer covering layer adopts the welding mode to be connected with pipe fitting safely and reliably; The centre accompanies one deck stainless steel bearing course, realizes different bearing capacity and temperature capacity; Length cuts into straight tube or is coiled into coil pipe on demand.
The stainless steel bearing course adopts Stainless Steel Band to twine welding fabrication at inner plastic pipe outer wall, can also utilize dissipate heat that circumferential winding welding the produces hot melt adhesion that stainless steel bearing course and inner plastic pipe outer wall is suitable together, the girth seam of stainless steel bearing course can also the reinforced plastic outer covering layer be moulded the heat that overlays on the stainless steel bearing course and is covered bonding force, and the flexible delamination that prevents from expanding separates.The stainless steel bearing course is clipped between inner plastic pipe, the plastics outer covering layer, compares homogeneity metal spiral welded tube and reaches same bearing capacity, can significantly reduce wall thickness; Simultaneously, because the roll bending rolling direction of spiral welded pipe is not vertical welding tube axis direction (its angle depends on the helix angle of welded tube), spiral weld place combined stress only has the 60-85% of ERW principal stress (radial stress), and, when having defective near the weld seam, because spiral weld is stressed less, so the danger of its expansion is also large not as straight weld, the phenomenon that can not cause longitudinal cracking occurs, thereby the cracking resistance of spiral welded pipe, static pressure blasting intensity, pliability and fatigue strength etc. are better than ERW, reach same bearing capacity, this stainless steel bearing course can reduce wall thickness 20%～40%.Adopt the winding welding fabrication technique of stainless steel bearing course, can make the stainless steel bearing course reaching under the same bearing capacity, reduce wall thickness 20%～40%; Can make stainless steel bearing course and inner plastic pipe outer wall hot melt adhesion, cover bonding with plastics outer covering layer heat; And produce the weld seam of circumferential spiral surrounding, prevent the normal radial and axial formation medium osmosis of peeling off that produces that uses; Can realize that cast is regular, even weld distributes, control mouth of pipe ovality; Compare with the straight seam welding moulding, can simplify welding equipment and mould, shorten production line length, reduce the requirement to Workplace.
Inner plastic pipe and medium contact can add the antibiotic auxiliary agent of Denging, realize the performances such as antibiotic; The plastics outer covering layer plays the effect that connects and protect, and can add the auxiliary agents such as uvioresistant, realizes anti-ultraviolet function; The stainless steel bearing course has pressure-bearing, the critical function such as heat-resisting.
The plastic composite pipe tube wall that the utility model provides is thin, lightweight, can also realize as required various bearing capacities and various serviceability temperature, need simultaneously to be applied to the pipeline of Nai Gaore and high pressure, also lightweight, connect reliable, can effectively replace copper, the pressure-bearing metal pipes such as stainless steel, as: solar water delivery pipe (requiring high heat and the high pressure of the anti-limit), the larger specification building internal riser of heating and production delivery, hot water central heating secondary pipe network is with managing, the idle call pipe that replaces soft attitude copper pipe, high voltage bearing mining nonmetallic pipe (also requiring lightweight), bright tubulature of anti-collision etc.
