Abstract
The utility model discloses a high-performance composite oil delivery pipe. The high-performance composite oil delivery pipe has a four-layered composite structure, sequentially comprises a high-density polyethylene layer, a metal framework layer, a nylon resin layer and a polyurethane layer from outside to inside, and is characterized in that the metal framework layer has a net-shaped framework structure which is formed by spirally twisting high-strength steel wires in the left-right direction; ultra-high molecular weight polyethylene hot melt glue is coated on the metal framework layer; the thickness of the coating layer of the ultra-high molecular weight polyethylene hot melt glue is 1.0-1.5mm; and the material of the high-density polyethylene layer is polyethylene with the molecular weight higher than 250 units. The high-performance composite oil delivery pipe is high in structure strength, high in pressure bearing capacity and long in service life, can stop leakage of oil, and has a high anti-static property and a high flame retardant property.
Description
Technical field
The utility model relates to a kind of tubing, relates in particular to a kind of polyethylene composite pipe.
Background technique
Polyvinyl piping materials is owing to having the features such as light weight, corrosion-resistant, long service life, be widely used in petroleum industry, in use, there is following point in the polyvinyl piping materials of finding prior art: fluid Seepage, cause fluid to run off, when serious, can, because of fluid leakage pollution environment, cause the accident; Tubing internal layer wears no resistance, and working life is short.
Model utility content
The utility model, for the deficiencies in the prior art, proposes a kind of obstruct fluid seepage, the high-performance composite oil pipeline of long service life.
The utility model is achieved through the following technical solutions technical goal.
High-performance composite oil pipeline, its improvements are: described high-performance composite oil pipeline is four layers of composite structure, are high-density polyethylene layer, metal frame layer, polyamide resin layer, polyurethane layer from outside to inside successively.
In said structure, described metal frame layer is the Wrapping formed mesh skeleton structure of high-tensile steel wires left-and-right spiral.
In said structure, on described metal frame layer, be coated with ultra-high molecular weight polyethylene hot melt adhesive, its coating layer thickness is 1.0～1.5mm.
In said structure, described high-density polyethylene layer material used is the polyethylene that molecular weight surpasses 250 units.
The utility model compared with prior art, has following good effect:
1, centre arranges polyamide resin layer, and nylon resin can resistance to various strong acid and most organic solvents such as 70% ethanol, dichloromethane, and stable chemical performance, can intercept fluid seepage.
2, internal layer is polyurethane internal layer, and wear resistance is the more than 10 times of cast iron tube, is the more than 4 times of manganese steel pipe, is the more than 12 times of Stainless Steel Tube, significantly improves wear resistance of the present utility model, significant prolongation the utility model working life.
3, metal frame layer adopts the Wrapping formed mesh skeleton structure of high-tensile steel wires left-and-right spiral, can make to the utlity model has good structural strength, bears higher pressure.
4, polyethylene middle layer employing material is the polyethylene that molecular weight surpasses 250 units, makes tubing have antistatic, flame retardant property preferably.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
High-performance composite oil pipeline shown in the drawings, is four layers of composite structure, is high-density polyethylene layer 1, metal frame layer 2, polyamide resin layer 3, polyurethane layer 4 from outside to inside successively; On metal frame layer 2, be coated with ultra-high molecular weight polyethylene hot melt adhesive, its coating layer thickness is 1.0～1.5mm.
In the present embodiment, metal frame layer 2 is the Wrapping formed mesh skeleton structure of high-tensile steel wires left-and-right spiral; High-density polyethylene layer 1 material used is the polyethylene that molecular weight surpasses 250 units.
