Description
Technical field
The present invention relates to anti-corrosion pipe technical field, especially a kind of steel polyethylene compound pipe.
Background technology
Polyethylene is a kind of aggregated obtained thermoplastic resin of ethene, odorless, nontoxic, has excellent lower temperature resistance
Can, chemical stability is good, is resistant to the erosion of most of soda acids, is a kind of good anti-corrosion material, so people are often attached by its
And carry out anti-corrosion to steel pipe on steel pipe, and then form existing steel polyethylene compound pipe, but existing steel polyethylene is compound
Connecting hole on the connecting portion of pipe is all connected by screw bolts, and, is turned bolt and is easy to due to connecting hole directly and bolt connection
The abrasion or destruction of the vinyon layer in connecting hole are caused, so as to result in pipeline corrosion protection poor performance, is substantially reduced
The service life of steel polyethylene compound pipe.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve the connection on the connecting portion of existing steel polyethylene compound pipe
Hole is all directly to be fixedly connected with bolt, turns the abrasion or broken that bolt easily causes the vinyon layer in connecting hole
It is bad, the problem of so as to result in pipeline corrosion protection poor performance, the invention provides a kind of steel polyethylene compound pipe, by setting poly- second
Alkene plastics rod enters to be about to connecting hole to be fixedly connected with bolt so that bolt directly contacts fixation with vinyon rod, effectively
Avoid the abrasion or destruction of the vinyon layer caused when turning bolt in connecting hole.
The technical solution adopted for the present invention to solve the technical problems is：A kind of steel polyethylene compound pipe, including steel pipe and
The vinyon layer being attached on steel pipe madial wall, steel pipe include body and connecting portion, the connecting portion include joint face and
The connecting hole being uniformly arranged on joint face, vinyon layer is attached with respectively on the joint face and connecting hole, in addition to
Vinyon rod, the vinyon rod are axially arranged with the screwed hole for connecting bolt, and the screwed hole is through poly-
The both ends of vinyl plastics rod, the vinyon rod are fixedly connected through connecting hole and with connecting hole.
In order to ensure that vinyon rod and connecting hole are fixed, the vinyon rod lateral surface is provided with outer spiral shell
Line, is provided with the internal thread being adapted with the external screw thread on vinyon rod in the connecting hole, the vinyon rod with
Connecting hole is threadedly coupled.
Specifically, in addition to joint face the sealing gasket matched, the sealing gasket is provided with the positioning convex of annular, described
Joint face is provided with the locating slot being adapted with positioning convex, not only acts as the effect of sealing, it is therefore prevented that the movement of sealing gasket, and
And the joint face contact-impact of adjacent two steel polyethylene compound pipe is avoided to cause the damage of vinyon layer on joint face.
Specifically, the thickness of the vinyon layer is 3mm-5mm.
Specifically, anti-corrosion enamelled coating is attached with the lateral wall of the steel pipe.
The beneficial effects of the invention are as follows：The invention provides a kind of steel polyethylene compound pipe, by joint face and connecting hole
The vinyon layer of attachment is connected as a single entity with the vinyon layer adhered on steel pipe madial wall, ensure that overall anti-corrosive properties
Energy；By setting vinyon rod to be indirectly connected with connecting hole and bolt, bolt pair is often turned so as to effectively avoid
The damage of vinyon layer, substantially prolongs service life in connecting hole, reduce use cost.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of steel polyethylene compound pipe of the present invention；
Fig. 2 is the structural representation of vinyon rod.
