Method.
Background technology
Polyvinyl piping materials（Also known as PE is managed）Connection is reliable, service life length, and has good low-temperature impact resistance, resists
Stress cracking resistance, chemical resistance and resistance to ag(e)ing, therefore various engineering pipelines can be made into and be widely used, such as city's political and ideological work
Various water pipes, tracheae, cable tube etc. in journey.Polyethylene pipe made of independent polythene material is usually managed with respect to composite polyethylene tube
Wall is thicker, and the polythene material not being used only is more, and voltage endurance capability is low, and intensity and toughness have been short of in some occasions.
Polyethylene composite pipe with steel wire mesh skeleton is a kind of new high-tech environmental-protecting chemical tubing just risen in recent years, with
The Wrapping formed mesh skeleton of high-tensile steel wires left-and-right spiral is reinforcement, using high density polyethylene (HDPE) as matrix, is had enough
Intensity and toughness.Steel wire mesh frame polyethylene compound pipe limited length during fabrication, generally only several meters or tens meters, during application
Need to be attached multiple tubing according to size requirement, but the interconnection technique of pipeline is not well solved so far.
In order to make the water resistance between the steel wire mesh framework polyethylene pipe of interconnection more preferable, at present, steel wire mesh frame
Connection mode between polyvinyl piping materials is mainly electric smelting connection.Electric smelting connection refers to gather two connected steel wire mesh frames
The end surface of ethylene tube or end face melting, can be connected as one after cooling, and the intensity of connector is higher than tubing bulk strength,
And the water resistance of joint is not much different with tubing body.But the defects of electric smelting connection mode, is：After the completion of connection
Inner wall at corresponding interface, which has, is partially exposed at outer steel wire, with the conveying of severe corrosive solution in pipeline, is exposed to
Outer steel wire is easily corroded, so as to influence the intensity and toughness of pipeline entirety, therefore realizes connection through the above way
Pipeline is also not used to conveying Chemical Manufacture strong acidic liquid at present.
The content of the invention
It is an object of the invention to provide a kind of good connecting effect, cost is low, can expand the steel wire of the tubing scope of application

The purpose of the present invention is so come what is reached, a kind of connection method of steel wire mesh frame polyethylene compound pipe, it is special
Sign is to comprise the following steps：
S1 the connection end of two steel wire mesh frame polyethylene compound pipes to be connected) is cut into vertical cross-section, and to this
Vertical cross-section is polished and cleaned；
S2) corrosion-inhibiting coating or welding are coated with respectively at the above-mentioned vertical cross-section of two steel wire mesh frame polyethylene compound pipes
There is gasket and be exposed to outer steel wire to cover；
S3) corrosion-inhibiting coating is coated with by two or connection end that welding has gasket aligns, and close to two connection ends
Insertion depth line is marked on the outer wall of steel wire mesh frame polyethylene compound pipe respectively, an electric melting pipe fittings are then inserted in two steel wires again
The connection end of network framework polyethylene compound pipe is simultaneously flush with the insertion depth line；
S4) electric melting pipe fittings are electrically connected with welding machine, starts two connection ends of welding after energization, makes electric smelting
The inner surface fusing of pipe fitting and the melt swell that produces and full of the gap between two connection ends, until the poly- second of steel wire mesh frame
The outer surface of alkene multiple tube also produces melt, and inside and outside melt is merged into each other two connection end hot melts integrally, and is cooled to
Room temperature.
In the specific embodiment of the present invention, the corrosion-inhibiting coating is epoxy anticorrosive coating, polyurethane anticorrosion
It is coating, acrylic acid corrosion-inhibiting coating, Vinylidene Chloride corrosion-inhibiting coating, chlorinated rubber corrosion-inhibiting coating, highly-chlorinated polyethylene coating, inorganic anti-
Any one in rotten coating.
In another specific embodiment of the present invention, the gasket is any one in PE, PVC, EVA gasket
Kind.
In another specific embodiment of the present invention, the corrosion-inhibiting coating and gasket have even curface,
And outer diameter is identical with multiple tube outer diameter.
After the present invention is as a result of the above method, compared with prior art, have an advantageous effect in that：It is anti-by smearing
Rotten coating adds gasket steel wire expose portion can be completely covered, so as to avoid in original technology because steel wire exposes
And it is subject in pipe reducing for the tubing intensity caused by solution corrosion, the service life of tubing is effectively extended, and suitable for defeated
Strong acidic liquid is sent, the scope of application can be expanded；Compressive resistance at pipe fitting is high, can guarantee that welding quality；Processing step is few, easily
In operation, ensure product quality.
