Description
[technical field]
The utility model relates to composite pipe technical field, specifically a kind of steel wire mesh frame polyethylene compound pipe.
[background technique]
Polyethylene compound pipe processes with the polyethylene resin of two kinds of different densities, but find in long-term practice process, still there is structural strength deficiency in this polyethylene compound pipe, particularly below road during tubing, traditional polyethylene compound pipe very easily deforms, and even occurs because being out of shape the seriously phenomenon of breaking; Therefore market there is a kind of metal reinforced polyethylene compound pipe, such as steel wire mesh framework polyethylene pipe material.
Steel wire mesh framework polyethylene pipe material not only combines plastic tube and steel pipe advantage separately, also solves the shortcomings such as plastic tube is not withstand voltage, steel pipe is not corrosion-resistant, possesses excellent flexility, is used in long apart from buried water system; Underground coal mine water supply, whitewashing pipe-line system etc.Be the first-selected product of the conventional pipelines such as current domestic replacement steel pipe, be widely used in the fields such as oil, rock gas, municipal engineering, industrial fluids conveying, colliery.
In NBS CJ/T189-2007, maximum tubing bore is DN630, and pressure maximum is 1.0mpa, now requires that pressure reaches 1.6Mpa, but the intensity of existing steel wire mesh framework polyethylene pipe material cannot reach.
[summary of the invention]
The purpose of this utility model is to overcome the technical problem existed in prior art, provides a kind of steel wire mesh frame polyethylene compound pipe of new structure.
For achieving the above object, design a kind of steel wire mesh frame polyethylene compound pipe, it is characterized in that body comprises five layers of composite bed of inner plastic layer, the first hot melt adhesive special layer, steel wire mesh frame, the second hot melt adhesive special layer and outer layer plastic layer, the outer layer ring of described inner plastic layer is to being coated with the first hot melt adhesive special layer, the outer layer ring of described first hot melt adhesive special layer is to being coated with steel wire mesh frame, the outer layer ring of described steel wire mesh frame is to being coated with the second hot melt adhesive special layer, and the outer layer ring of described second hot melt adhesive special layer is to being coated with outer layer plastic layer; The size of described composite pipe limits as follows: the maximum tubing bore 630mm of described composite pipe, inner plastic thickness T equals 19mm, steel wire mesh frame diameter D equals 1.2mm, and first and second hot melt adhesive special thickness is more than or equal to 3mm, and outer layer plastic thickness is more than or equal to 4mm.
Be seamless coated between five layers of composite bed in described composite pipe, i.e. zero clearance between adjacent two layers composite bed.
Described steel wire mesh frame is formed by steel wire winding, and the winding angle a of described steel wire is more than or equal to 49.5 °, and winding angle a is less than or equal to 56 °, and winding direction adopts left-handed+dextrorotation, and section wire number is 400.
Described body nominal wall thickness and limit deviation are more than or equal to 26+2.0mm.
The utility model satisfactorily meets the pressure usage requirement of project.
