Abstract

The utility model discloses a kind of plastic-coated steel for being capable of anti-dropout and antistatic, including the steel pipe being made up of inner and outer tubes, toroidal cavity is provided between inner and outer tubes, the inner and outer surfaces of steel pipe are equipped with projection, and coating layer is connected by glue-line, electric installation is provided with interior coating layer, one group of conductor rod is connected on electric installation, conductor rod is set through steel pipe and outer coating layer.Advantage of the present utility model:Cavity provided with annular in steel pipe, it lightens relative to existing tube quality, save raw material, it is easily installed, pass through projection connection coating layer, effectively enhance the frictional resistance between steel pipe and plastic layer, prevent plastics deformation of expanding with heat and contract with cold flexible, eliminating stress and concentrating causes the possibility of inner liner drawing crack, so as to substantially increase the connection fastness of coating layer and steel tube surface, plastic-coated, which is not readily separated, to come off, the electrostatic produced by can effectively being prevented in pipe by electric installation and conductor rod.

Description

A kind of plastic-coated steel for being capable of anti-dropout and antistatic
Technical field
The utility model is related to pipe technology field, more particularly to a kind of plastic-coated steel for being capable of anti-dropout and antistatic.
Background technology
Plastic-coated steel is to play protection steel pipe inner wall by heating one layer of plastic layer on steel pipe inner wall with plastic spraying A kind of pipeline, typically needs to handle the inwall of steel pipe before plastic-coated, such as ball blast, derusting operation, makes the interior of steel pipe Wall is as far as possible bright and clean, the being firmly combined with property of increase coating layer and steel pipe inner wall, but plastic-coated steel often occurs in normal use The phenomenon of coating layer rupture, this is due to that the thermal coefficient of expansion gap of steel pipe and coating layer is caused greatly very much, in the identical temperature difference Under, the thermal volume expansion of coating layer will be far longer than the thermal volume expansion of steel pipe in itself, so in the larger situation of difference variation Under, coating layer easily produces retractility stripping, separates and comes off with steel pipe when serious, loses the protective effect of coating layer, and this Elongation percentage difference is planted to increase as temperature is raised, especially when caliber is larger, big lining area relative accumulation deformation Amount is big, and coating is more prone to shrink, ftractures, separates and comes off.Caliber is more than 600mm pipe, because people can enter in pipeline Operation, therefore can be in inner surface of tube by measures such as welding, being welded to connect steel wire, stud etc. in inner surface of tube prevents Stripping measure.And for the less plastic-coated steel of caliber, staff cannot be introduced into be repaired inside pipeline, Zhi Nenggeng Pipeline is changed, so as to add the maintenance cost of equipment.Simultaneously because plastic product easily produces electrostatic, electrostatic easily causes electric fire Flower, so as to cause blast, causes the generation of security incident.
Utility model content
The purpose of this utility model is that, in order to solve shortcoming present in prior art, and the one kind proposed being capable of anti-dropout With the plastic-coated steel of antistatic.
To achieve these goals, the utility model employs following technical scheme:
A kind of plastic-coated steel for being capable of anti-dropout and antistatic, including steel pipe, are applied in the outer surface of the steel pipe provided with outer Layer is moulded, internal plastic coating layer is provided with the inner surface of the steel pipe, it is characterised in that:The steel pipe includes inner tube, in said inner tube Outside is socketed outer tube, and toroidal cavity is provided between said inner tube and outer tube, one is passed through respectively in the both sides of the toroidal cavity Retainer ring is fixed together inner and outer tubes, and the inwall of said inner tube is provided with projection, and the outer wall of the outer tube also is provided with It is raised;
Said inner tube is adhesively fixed internal plastic coating layer by inner glue layer, and the outer tube is adhesively fixed described by outer glue-line Outer coating layer;
Electric installation is provided with internal plastic coating layer, one group of conductor rod, the wire are connected on the electric installation Bar is set through the steel pipe and outer coating layer.
Preferably, the electric installation includes connecting between one group of ring shaped conductive bar be arrangeding in parallel, the ring shaped conductive bar One group of connection conducting rod is connect, the conductor rod is connected in the connection conducting rod.
The utility model has the advantage of:A kind of Clad Steel for being capable of anti-dropout and antistatic provided by the utility model Pipe, the cavity provided with annular in steel pipe, it lightens relative to existing tube quality, saves raw material, is easily installed, Because the inner and outer surfaces in steel pipe are by projection connection coating layer, the friction resistance between steel pipe and plastic layer is effectively enhanced Power, preventing plastics to expand with heat and contract with cold, deformation is flexible, and eliminating stress and concentrating causes the possibility of inner liner drawing crack, so as to carry significantly The high connection fastness of coating layer and steel tube surface, plastic-coated, which is not readily separated, to come off, can be effective by electric installation and conductor rod Electrostatic produced by preventing in pipe.
