Description
Technical field
The utility model relates to plastic tube technical field, is specifically related to a kind of anti-aging plastic-coated PE steel-plastic composite pipe.
Background technique
Steel-plastic composite pipe is generally with seamless steel pipe, welded steel pipe for base tube, the compound pipe of interior finishing polyethylene powders.Because it has the feature of steel and plastics concurrently, the construction identical with conventional steel can not only be carried out, and there is high strength and durability, and more cheap than stainless-steel pipe, be progressively applied to the fields such as high-floor feedwater, industrial water, pipe used in mine, rainwater-collecting conveying.But out of doors in using process, find to be coated in outer field polythene material under the effect of air, sunlight and oxygen, can occur aging, variable color, chap, become fragile or efflorescence, even lose its mechanical property, be therefore unfavorable for that the long-term normal of steel-plastic composite pipe uses.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-aging plastic-coated PE steel-plastic composite pipe, due to the introducing of anti-aging layer, the utility model is made to have good antiageing effect, long service life, the utility model has higher compression resistance simultaneously, can extensive use be various feedwater piping.
The purpose of this utility model is achieved by following technical solution:
A kind of anti-aging plastic-coated PE steel-plastic composite pipe, comprises skin, mesosphere and internal layer, described skin and internal layer are respectively polyethylene layer, described mesosphere is zinc-plated steel layer, and described outer outside is also provided with the first anti-aging layer, is also provided with the second anti-aging layer inside described internal layer.
Preferably, described anti-aging layer is the polyethylene anti-aging layer being added with antioxidant and light stabilizer.
Preferably, between described internal layer and mesosphere, be provided with tie layer, between described skin and mesosphere, be provided with tie layer.Internal layer, mesosphere, outer compact siro spinning technology are got up by tie layer by the utility model, add the integrity of composite water pipe.Further preferably, described tie layer is heat-fusing glue layer.
Preferably, described outer field wall thickness value is greater than the wall thickness value of described first anti-aging layer; The wall thickness value of described internal layer is greater than the wall thickness value of described second anti-aging layer.Further preferably, described skin is 3:1 with the ratio of the wall thickness value of described first anti-aging layer; Described internal layer is 3:1 with the ratio of the wall thickness value of described second anti-aging layer.Inventor finds, when described internal layer, described skin are 3:1 with the ratio of anti-aging layer respectively, can ensure that product reaches good aging-resistant effect, meet quality requirement in an experiment, simultaneously wananty costs advantage again.
The anti-aging plastic-coated PE steel-plastic composite pipe that the utility model provides is due to the introducing of anti-aging layer, product is made to have aging quality resistance, the application of mesosphere galvanizing by dipping steel layer, make composite water pipe can be high pressure resistant, the composite pipe that the utility model provides has etch-proof performance, and long service life, can promote the use of in supply pipe.
Compared with prior art, the utility model has following beneficial effect:
The utility model anti-aging plastic-coated PE steel-plastic composite pipe is composited by multilayer tubing, middle level is electro-galvanized steel tube layer, compressive strength is high, outer and internal layer is polyethylene layer, there is non-scaling, rustless advantage, in addition, inside outer outside of the present utility model and internal layer, be respectively arranged with polyethylene anti-aging layer, containing antioxidant and light stabilizer in described polyethylene anti-aging layer, composite water pipe is made to have aging-resistant performance; The utility model can be used for the large potable water of discharge pressure and long service life of the present utility model.
