Abstract
A polythene adhesive tape jacket pipe belongs to the technical field of pipeline corrosion prevention for oil field and solves the problem of poor corrosion prevention generated against prior art. The technical scheme as follows: The utility model comprises a steel pipe, an inner layer made with P19 under glue, a medium player made with polythene adhesive tape, an external wall of the medium layer, a protective layer of polythene which integrates with the external wall of the medium layer. The external wall of the utility model uses a protection layer made with polythene plastic which integrates with the medium layer made with polythene adhesive tape for once molding, characterized by smooth surface and absent defect. The polythene, formed by high temperature of extrusion attaches to the steel pipe wrapped with the adhesive tape and keeps close association with the steel pipe wall, characterized by absent gap, absent defect, abrasion resistance, corrosion prevention and enhanced mechanical performance, which can reduce the loss generated during transport and pipe distribution. The structure of polythene adhesive tape jacket pipe can replace an epoxy coal tar pitch for corrosion prevention and assure a qualified steel pipeline and extend the service life of the steel pipeline only using polythene adhesive tape for corrosion prevention.
Description
Technical field:
The utility model belongs to oil field pipe aseptic technic field, especially relates to the strong polyethylene tape jacket tube of a kind of corrosion resistance.
Background technique:
At present, the epoxide coal bituminous anticorrosion and polyethylene glue adhesive tape structural anticorrosion of the anticorrosion employing buried steel of oil field pipe, epoxide coal bituminous anticorrosionly form by one deck priming paint and multilayer finish paint, can add glass cloth between top coat layer strengthens, this anticorrosion form is subjected to weather, Temperature Influence bigger when producing, construction environment is abominable, and at transportation, fragile anticorrosive coat in the on-the-spot stringing process, makes anticorrosive coat not reach antisepsis.Polyethylene glue adhesive tape structure be band in one deck priming paint and one deck, one deck in addition, have a common boundary width by adjustment, increase anticorrosion grade, this polyethylene glue adhesive tape is shorter relatively working life, wear resistance, corrosion resistance relatively a little less than.
Summary of the invention:
Technical problem to be solved in the utility model provides a kind of long service life, wear-resisting, polyethylene tape jacket tube that corrosion resistance is strong, to overcome the defective that prior art exists.
The technical solution of the utility model is: comprise steel pipe, P19 primer internal layer, and the polyethylene tape mesosphere, polyethylene tape mesosphere outer wall is integral with it and is provided with the polyvinyl plastics protective coating.
Outer adopt polyvinyl plastics protective coating and the once-through of intermediate layer polyethylene adhesive tape of the present utility model, product surface is smooth, zero defect, the polyethylene that process high temperature is extruded is attached on the steel pipe that twines adhesive tape, combine closely with tube wall, voidlessness, wear-resisting, corrosion resistance, mechanical property strengthen, thereby the loss that causes at transportation, cloth tube field in the minimizing work progress, the polyethylene tape jacket tube of this structure is anticorrosion to be substituted epoxide coal bituminous anticorrosionly, guarantees the steel pipeline anti-corrision quality, and prolongs the simple steel pipe polyethylene sealing tape corrosion-resistant working life of using.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
With reference to accompanying drawing, the utility model comprises that steel pipe 1, thickness are P19 primer internal layer 2, the polyethylene tape mesosphere 3 of 80-200 μ m, polyethylene tape mesosphere 3 its thickness are common 〉=0.7mm, reinforcement 〉=1.4mm, polyethylene tape mesosphere 3 outer walls and its once-through are provided with the polyvinyl plastics protective coating of extruding through high temperature 4, and its thickness is 2-3mm.
