Description
Technical field
It the utility model is related to plastic-coated steel technical field, more particularly to a kind of antistatic plastic-coated steel.
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 need to handle the inwall of steel pipe before plastic-coated, such as ball blast, derusting operation, make the interior of steel pipe
Wall is as far as possible bright and clean, increases the being firmly combined with property of coating layer and steel pipe inner wall, but plastic-coated steel often occurs in normal use
The phenomenon of coating layer rupture, this be due to the thermal coefficient of expansion gap of steel pipe and coating layer it is too big caused by, 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
Kind elongation percentage difference increases as temperature raises, especially when caliber is larger, the deformation of big lining area relative accumulation
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 inside pipeline and be repaired, 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 to explode, causes the generation of security incident.
Utility model content
The purpose of this utility model is and a kind of antistatic plastic-coated proposed in order to solve shortcoming present in prior art
Steel pipe.
To achieve these goals, the utility model employs following technical scheme：
A kind of antistatic plastic-coated steel, including steel pipe, it is characterised in that：Outer coating layer is provided with the outer surface of steel tube,
One group of conducting rod is also uniformly provided between outer coating layer and steel pipe, heat-insulation layer is provided with the outside of the outer coating layer, described
The inner surface of steel pipe is provided with internal plastic coating layer, and flange is fixedly connected with steel pipe one end, conductive coil is provided with inside flange, each described
Conducting rod penetrates the flange and is connected with conductive coil, and vertical rod is provided with the outside of the flange, and vertical rod penetrates flange
Inside and be connected with conductive coil.
Preferably, each conducting rod is each along the axially arranged of the steel pipe.
Preferably, the heat-insulation layer is heat insulation tile lamella, and heat insulation tile lamella is wrapped in the outside of outer coating layer.
Preferably, one group of fixing hole is provided with the end face of the flange, gasket seal is provided with the outside of flange.
Preferably, the outer surface of the steel pipe is provided with one group of sags and crests, and one group also is provided with the inner surface of the steel pipe
Sags and crests.
Preferably, the outer coating layer is epoxy resin layer.
Preferably, the internal plastic coating layer is PE layers.
The utility model has the advantage of：The utility model provides a kind of antistatic plastic-coated steel, due to plastic-coated steel
Outside parcel insulation tile, effectively maintains the temperature in pipe, and being located at conducting rod in steel pipe can will be quiet caused by friction
Electricity is exported at flange-interface, and imports ground end by vertical rod, to prevent due to flammable liquid in the excessive ignitron of accumulation of static electricity
Or gas, the sags and crests that the interior outside of steel pipe is provided with can strengthen tack of the coating layer to steel pipe, prevent coming off for coating layer.
