Abstract
The utility model discloses a composite steel tube with a glass reinforced plastic tube lined inside and relates to the field of oil filed gathering and transportation and water filling pipelines. The composite steel tube comprises a steel tube, wherein the glass reinforced plastic tube with a descaling layer on the inner wall is arranged in the steel tube, a metal wire layer is arranged on the outer wall of the steel tube, a thermal insulation layer is arranged on the outer side of the metal wire layer, and anti-corrosion painting is painted on the outer side of the thermal insulation layer. The composite steel tube with the glass reinforced plastic tube lined inside is used in projects of oil field gathering and transportation and water filling, is reasonable in structure design and ingenious and novel in concept, prevents phenomena of fracture and deformation caused by geological changing due to the metal wire layer outside the steel tube, is suitable for being buried directly, is applicable to engineering having thermal insulation requirements, has wide using prospect as a conveying pipeline, and is convenient to construct, low in maintenance cost and easy to popularize and use in a large scale.
Description
Technical field:
The utility model relates to oil field gathering and transportation, filling pipe field, and what be specifically related to is a kind of inner-lining glass for steel tube steel pipe.
Background technique:
At present China oil field, some liquid of mine are carried, and adopt metal tube or nonmetal multiple tube more, and metallic conduit is when carrying liquid, and scale formation is serious, and is perishable, some races often occur, emit phenomenon such as leakage, and the working life of pipeline is short; But not metal composite pipe is then produced, installation cost is higher; In these pipeline construction difficulties of ground such as coastal, soldering point is many, and the maintenance cost height produces fed sheet of a media and to pollute, and has seriously restricted the application of these pipelines.
The model utility content:
For the not enough the utility model that overcomes in the background technique provides a kind of good antiscale property, corrosion resistant inner-lining glass for steel tube steel pipe.
In order to solve the problem that exists in the background technique, the utility model is by the following technical solutions: a kind of inner-lining glass for steel tube steel pipe, comprise steel pipe, it is characterized in that: steel duct is provided with the Glass Steel Tube that inwall has the scale removal layer, outer wall of steel pipe is provided with metal wire layer, the metal wire layer outside is provided with thermal insulation layer, and the thermal insulation layer outside is brushed with corrosion resistant coating.
Described scale removal layer is the modified epoxy layer.
Described thermal insulation layer is the foaming pvdf layer.
Described metal wire layer is equidistant evenly to be wrapped on the steel pipe clockwise.
Described metal wire layer is cross-shaped to be wrapped on the steel pipe.
The beneficial effects of the utility model are: the utility model is used for oil field gathering and transportation, water filling project, reasonable in design, novelty is skillfully constructed, owing to outside steel pipe, be provided with metal wire layer, avoided the phenomenon that fractures, be out of shape occurring because geology changes, make pipeline be more suitable for the characteristics of direct-burried, but also be applicable in the engineering with insulation requirement, have more the use prospect as conveyance conduit.Be convenient to construction, maintenance cost is very low, and is easy to large-scale promotion application.
Description of drawings:
Fig. 1 is generalized section of the present utility model.
Fig. 2 is the schematic representation of metal wire layer spiral winding process.
Fig. 3 is the schematic representation of metal wire layer intersection winding process.
Embodiment:
Referring to each figure, this embodiment is by the following technical solutions, a kind of inner-lining glass for steel tube steel pipe, comprise steel pipe 4, it is characterized in that: steel pipe 4 inside are provided with the Glass Steel Tube 5 that inwall has scale removal layer 6, steel pipe 4 outer walls are provided with metal wire layer 3, and metal wire layer 3 outsides are provided with thermal insulation layer 2, and thermal insulation layer 2 outsides are brushed with corrosion resistant coating 1.Described scale removal layer 6 is the modified epoxy layer.Described thermal insulation layer 2 is the foaming pvdf layer.Described metal wire layer 3 is equidistant evenly to be wrapped on the steel pipe 4 clockwise.Described metal wire layer 3 cross-shaped being wrapped on the steel pipe 4.When the utility model is made, metal wire layer 3 is wrapped on the steel pipe 4, then steel pipe 4 and the Glass Steel Tube 5 that has scale removal layer 6 is combined with each other, again thermal insulation layer 2 and corrosion resistant coating 1 are fixed on the steel pipe 4, to the thickness that meets product requirement, solidify.The utility model is used for oil field gathering and transportation, water filling project, reasonable in design, novelty is skillfully constructed, because metal wire layer 3 is folded in inside, can not expose, and can prevent corrosion wiry, also avoided the phenomenon that fractures, be out of shape occurring because geology changes, make pipeline be more suitable for the characteristics of direct-burried, but also be applicable in the engineering with insulation requirement, have more the use prospect as conveyance conduit.Be convenient to construction, maintenance cost is very low, and is easy to large-scale promotion application.
