Description
Technical field
This utility model relates to plastic-coated pipeline technical field, and particularly relate to a kind of plastic-coated steel connects sealed joint pipe soon.
Background technology
Plastic-coated steel is a kind of pipeline by playing protection steel pipe inner wall on steel pipe inner wall with one layer of plastic layer of plastic spraying hot melt, its excellent performance.Compared with galvanized pipe, have anticorrosive, non-corrosive, not dirty, smooth smoothness, clean nontoxic, service life the advantage such as length.According to test, the service life of steel-plastics composite pipe is more than three times of galvanized pipe.Compared with plastic tube, there is mechanical strength high, the advantage such as pressure, heat-resist.Owing to matrix is steel pipe, so there is not embrittlement, problem of aging.Can be widely applied to the fluid conveyings such as tap water, coal gas, chemical products and heating engineering.Coating steel pipe is to apply plastics on the basis of large-caliber spiral welded tube and ratio-frequency welded tube to form, application of polyvinyl (PVC) can be needed according to different, polyethylene (PE), the plastic coating of the various different performances such as epoxy resin (EPOZY), adhesive force is good, corrosion resistance is strong, it is resistant to strong acid, highly basic and other chemical attack, nontoxic, not corrosion, wear-resisting, impact resistance, osmotic-pressure-tolerant is strong, pipe surface is smooth, do not adhere to any material, resistance during conveying can be reduced, improve flow and transfer efficiency, reduce discharge pressure loss, by updating the Recipe of powdery paints, make that the respective coatings performance of formation is more prominent has become as certainty.In coating solvent-free, material can not be oozed out, because of without the medium that carried of pollution, thus ensure clarity and the wholesomeness of fluid, can cold cycling be used alternatingly-40 DEG C to+80 DEG C of scopes, the most aging, do not chap, thus can use under the harsh environments such as cold zone.
In the whole pipeline of construction, need most the problem of solution be one, anticorrosion；Two, No leakage.For pipeline, plastic-coated steel solves pipeline service life the most substantially, i.e. antiseptical problem, but, for the connection between pipe, remain in many defects.If current connected mode, plug together connection: in one end enlarging of steel pipe, the other end reducing of steel pipe or maintain normal bore, the flared end of adjacent two plastic-coated steels plugs together be connected with necking end or normal bore end, then carry out welding or do other preservative treatments with regard to contact point, during welding, coming off of solder joint position anticorrosive coat certainly will be caused, affect service life.End sealing of tube mode: for using end sealing of tube, i.e. holds one end of pipe to be welded on the end of a steel pipe, and the other end of end pipe is welded on the end of another steel pipe, by end pipe two plastic-coated steels of series connection, the most easily there is solder joint and comes off the problem causing leakage.Groove and the mode that is connected of pipe collar: on the outer wall at the two ends of steel pipe, groove is set, after two plastic-coated steel docking, pipe collar is used to be buckled on the groove of two plastic-coated steels, by making two plastic-coated steels be together in series after pipe collar locking groove, although this mode applied range, use simple, but, the anticorrosion majority of current pipe collar uses corrosion resistant coating, antiseptic effect is bad, causing pipe collar corrosion to get loose, in turn result in the problem of leakage be to have generation, and existing plastic-coated steel needs the instrument of auxiliary when connecting, and connect bothersome arduously.
Utility model content
The purpose of this utility model is to solve shortcoming present in prior art, and a kind of plastic-coated steel proposed connect sealed joint pipe soon.
To achieve these goals, this utility model adopts the technical scheme that
A kind of plastic-coated steel connect sealed joint pipe soon, including plastic-coated steel, it is characterized in that: be equipped with a bulge loop at the two ends of plastic-coated steel, outer wall at the plastic-coated steel near each bulge loop is equipped with one section of external screw thread, an annular slot it is equipped with in each bulge loop, it is provided with a connecting tube between adjacent two plastic-coated steels, an annular plate coordinated of stepping down with corresponding described annular slot it is equipped with in the both sides of connecting tube, it is respectively provided on two sides with an annular baffle ring at connecting tube outer wall, a locking tube it is socketed respectively in the both sides outside connecting tube, the side of described locking tube is provided with and the annular spacing annular stop plate coordinated of baffle ring, the female thread of connection corresponding with described external screw thread it is additionally provided with in described locking tube.
Preferably, each described annular baffle ring is all socketed a sealing ring, is provided with the annular slot coordinated with annular baffle ring in the inner side of described sealing ring.
Preferably, described connecting tube includes steel pipe, is provided with epoxy layer in the inner side of described steel pipe, outside is provided with polyethylene layer.
Preferably, described locking tube includes steel pipe, is provided with epoxy layer in the inner side of described steel pipe, outside is provided with polyethylene layer.
The utility model has the advantage of: a kind of plastic-coated steel provided by the utility model connect sealed joint pipe soon, without aid, simple to operate, connect rapidly, good sealing effect, inwall in connecting tube and locking tube is respectively provided with epoxy layer simultaneously, outer wall arranges polyethylene layer makes its favorable anti-corrosion effect, considerably increases its service life.
