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 since connecting hole is directly with being bolted, is turned bolt and is easy to
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.
Utility model content
The technical problems to be solved in the utility model is：In order to solve on the connecting portion of existing steel polyethylene compound pipe
Connecting hole is all directly to be fixedly connected with bolt, turn bolt easily cause vinyon layer in connecting hole abrasion or
Person destroys, so that the problem of result in pipeline corrosion protection poor performance, the utility model provides a kind of steel polyethylene compound pipe, passes through
Vinyon rod is set to be fixedly connected into connecting hole is about to bolt so that bolt directly contacts solid with vinyon rod
It is fixed, effectively avoid the abrasion or destruction of the vinyon layer caused when turning bolt in connecting hole.
Technical solution is used by the utility model solves its technical problem：A kind of steel polyethylene compound pipe, including steel
The vinyon layer on steel pipe madial wall is managed and is attached to, steel pipe includes tube body and connecting portion, and the connecting portion includes connection
Face and the connecting hole being uniformly arranged on joint face, are attached with vinyon layer on the joint face and connecting hole, also respectively
Including vinyon rod, the vinyon rod is axially arranged with the threaded hole for connecting bolt, and the threaded hole runs through
In the both ends of vinyon rod, the vinyon rod is 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 equipped with outer spiral shell
Line, is equipped 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, further include described with the matched gasket of joint face, positioning protrusion of the gasket equipped with annular
Joint face is equipped with the locating slot being adapted with positioning protrusion, not only acts as the effect of sealing, it is therefore prevented that the movement of 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 utility model are：The utility model provides a kind of steel polyethylene compound pipe, by joint face and
The vinyon layer adhered on connecting hole is connected as a single entity with the vinyon layer adhered on steel pipe madial wall, ensure that entirety
Antiseptic property；By setting vinyon rod to be indirectly connected with connecting hole and bolt, often twisted so as to effectively avoid
Dynamic damage of the bolt to vinyon layer in connecting hole, substantially prolongs service life, reduces use cost.
