Abstract
The invention discloses a composite oil delivery pipe with high performance. The composite oil delivery pipe with high performance is four-layer composite structure composed of a high density polyethylene layer, a metal frame layer, a nylon resin layer and a polyurethane layer from the outer part to the inner part; further improvement is as follows: the metal frame layer is the mesh frame structure formed by the high-tensile steel wire wound at the left and right sides in a spiral winding mode; the ultra-high molecular weight polyethylene hot melt glue is coated outside the metal frame layer, the coating thickness is 1.0 to 1.5 <mm>; the material of the high density polyethylene layer is the polyethylene, the molecular weight of which is greater than 250 units. The composite oil delivery pipe with high performance I high in structure strength, strong in bearing capability and long in service life; the oil liquid leakage can be obstructed; and the composite oil delivery pipe with high performance has better anti-static electricity and inflaming retarding properties.
Description
Technical field
The present invention relates to a kind of tubing, particularly relate 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, find that the polyvinyl piping materials of prior art exists following point: fluid Seepage, fluid is caused to run off, because of fluid leakage pollution environment, can cause the accident time serious; Inner tubing layers wears no resistance, and working life is short.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of obstruct fluid seepage, the high-performance composite oil pipeline of long service life.
The present invention 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, described metal frame layer is 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 of molecular weight more than 250 units.
The present invention compared with prior art, has following good effect:
1, centre arranges polyamide resin layer, and nylon resin can most organic solvent such as resistance to various strong acid and 70% ethanol, dichloromethane, and stable chemical performance, can intercept fluid seepage.
2, internal layer is polyurethane internal layer, and wear resistance is more than 10 times of cast iron tube, is more than 4 times of manganese steel pipe, is more than 12 times of Stainless Steel Tube, significantly improves wear resistance of the present invention, significant prolongation working life of the present invention.
3, the mesh skeleton structure that metal frame layer employing high-tensile steel wires left-and-right spiral is Wrapping formed, can make the present invention have good structural strength, bear higher pressure.
4, polyethylene middle layer adopts material to be the polyethylene of molecular weight more than 250 units, makes tubing have antistatic, flame retardant property preferably.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below with reference to the accompanying drawings and the invention will be further described in conjunction with the embodiments.
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; Metal frame layer 2 is 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 of molecular weight more than 250 units.
