Abstract
A kind of PE steel-plastics composite pipe, the multiple tube include internal layer, middle layer and outer layer, and the internal layer and outer layer are modified PE material, and the middle layer is steel plate；Binding resin is equipped between the internal layer and middle layer, between middle layer and outer layer；The advantages that present invention provides a kind of PE steel-plastics composite pipe, has and increases internal pressure resistance to compression degree and external pressure ring stiffness, reduces plastics weight, reduce cost.
Description
Technical field
The present invention relates to tubing technical fields, and in particular to a kind of PE steel-plastics composite pipe.
Background technique
PE(polyethylene) pipeline is one of most common pipeline, with low-temperature impact resistance, resistant to chemical etching, wear-resisting etc.
Advantage, water supply, draining, heat supply, for being all used widely in combustion gas, agricultural irrigation, hydraulic engineering and various commercial plants.
Polyethylene is that typical thermoplastic is popularized since it has the characteristics that odorless, tasteless, nontoxic
Use, but in some environment relatively rugged environments or in some other critical facility engineerings, for bearing capacity it is bigger or
It is heavier some important places, the tensile strength of PE pipe does not reach requirement, is not able to satisfy actual production and use.
Summary of the invention
(1) the technical issues of solving
The present invention provides a kind of PE steel-plastics composite pipe, has and increases internal pressure resistance to compression degree and external pressure ring stiffness, reduces plastics weight, drop
The advantages that inexpensive.
(2) technical solution used
The present invention to achieve the above object, is achieved by the following technical programs: a kind of PE steel-plastics composite pipe, the multiple tube
Including internal layer, middle layer and outer layer, the internal layer and outer layer are modified PE material, and the middle layer is steel plate；The internal layer
Binding resin is equipped between middle layer, between middle layer and outer layer.
The steel plate is by rolling the socket being welded as a further optimization of the solution,.
A kind of preparation process of PE steel-plastics composite pipe, which is characterized in that the preparation process is the following steps are included: (1) is first
Inner tube is squeezed out by extruder；(2) after in inner tube extrusion bonding resin adhesive layer；(3) cladding steel pipe band is squeezed out；
(4) steel pipe band is rolled by high-frequency heating soldering apparatus and is welded into socket；(5) the extrusion bonding resin glue on steel socket
Layer；(6) finally in cladding outer tube.
(3) beneficial effect
The present invention provides a kind of PE steel-plastics composite pipe, has the advantages that
The configuration of the present invention is simple, preparation are easy, and the multiple tube prepared through the invention, which has, increases internal pressure resistance to compression degree and outer press ring
The advantages that rigidity reduces plastics weight, reduces cost.
Specific embodiment

A kind of PE steel-plastics composite pipe, the multiple tube include internal layer, middle layer and outer layer, and the internal layer and outer layer are to change
Property PE material, the middle layer be steel plate；Bonding tree is equipped between the internal layer and middle layer, between middle layer and outer layer
Rouge.
The steel plate is by rolling the socket being welded as a further optimization of the solution,.
A kind of preparation process of PE steel-plastics composite pipe, which is characterized in that the preparation process is the following steps are included: (1) is first
Inner tube is squeezed out by extruder；(2) after in inner tube extrusion bonding resin adhesive layer；(3) cladding steel pipe band is squeezed out；
(4) steel pipe band is rolled by high-frequency heating soldering apparatus and is welded into socket；(5) the extrusion bonding resin glue on steel socket
Layer；(6) finally in cladding outer tube.
The configuration of the present invention is simple, preparation are easy, and the multiple tube prepared through the invention, which has, increases internal pressure resistance to compression degree and outer
The advantages that pressure ring rigidity reduces plastics weight, reduces cost.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
