Abstract
The utility model belongs to the field of oil and gas pipelines, and particularly relates to an anticorrosive steel pipe for oil and gas transportation. The anticorrosive steel pipe for oil and gas transportation comprises a steel pipe base body, an epoxy powder layer is coated to the outer wall of the steel pipe base body, and a polyolefin layer is stuck to the periphery of the epoxy powder layer via an adhesive layer. The steel pipe has simple structure and convenience for manufacturing, excellent chemical media resistance of the epoxy powder layer and excellent moisture permeation resistance and mechanical protection performance of the polyolefin layer are integrated, so that double protection can be performed on the steel pipe. The steel pipe has good corrosion resistance and is especially applicable to the long-distance transportation of heavy viscous crude oil, fuel oil or natural gas and the like.
Description
Technical field
The utility model relates to a kind of anti-corrosive steel tube that oil gas is carried that is used for, and belongs to the oil and gas pipes field.
Background technique
Along with domestic increase to the oil gas demand, increasing oil gas is carried by land route transportation commonly used and is changed line transportation into.Line transportation has easy care, carries advantages such as cost is low, transfer efficiency height.But if will grow distances heavy stickiness crude oil, fuel oil or natural gas etc.; Just need do preservative treatment to steel pipe; The method that traditional steel pipe is employed in steel pipe matrix surface spraying individual layer epoxy powder is carried out anticorrosion, but owing to can have leak source, the as easy as rolling off a log corrosion that causes steel pipe of these leak sources in the spraying process; Therefore this antiseptic effect is poor, and is unfavorable to steel pipe.
The model utility content
According to above deficiency of the prior art, the technical problem that the utility model will solve is: the anti-corrosive steel tube that oil gas is carried that is used for that a kind of simple in structure, easy to make and favorable anti-corrosion effect is provided.
The utility model solves the technological scheme that its technical problem adopted: the described anti-corrosive steel tube that is used for the oil gas conveying; Comprise the steel pipe matrix; Be coated with the epoxy powder layer on the outer wall of steel pipe matrix, it is characterized in that: the periphery of epoxy powder layer is stained with polyolefin layer through the glue bond layer.
The polyolefin layer that is stained with outward through outer epoxy powder layer that sprays of steel pipe matrix and epoxy powder layer can carry out the bilayer protection to steel pipe; Thereby can significantly strengthen the antiseptic effect of steel pipe, be applicable to long distances heavy stickiness crude oil, fuel oil or natural gas etc.
The beneficial effect that the utility model had is:
This steel-pipe construction is simple, easily manufactured; Chemical mediator-resitant property and splendid water-fast impervious and the mechanical protection performance of polyolefin layer that integrated epoxy powder layer is excellent; Thereby can carry out the bilayer protection to steel pipe; Corrosion resistance and good is particularly suitable for long distances heavy stickiness crude oil, fuel oil or natural gas etc.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1, steel pipe matrix; 2, epoxy powder layer; 3, glue bond layer; 4, polyolefin layer.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done and to further describe:
As shown in Figure 1, be used for the anti-corrosive steel tube that oil gas is carried, comprise steel pipe matrix 1, be coated with epoxy powder layer 2 on the outer wall of steel pipe matrix 1, the periphery of epoxy powder layer 2 is stained with polyolefin layer 4 through glue bond layer 3.
Because epoxy powder has excellent chemical mediator-resitant property; Polyolefin has splendid water-fast impervious and mechanical protection performance; Therefore; Epoxy powder layer 2 and the epoxy powder layer 2 outer polyolefin layer 4 that is stained with through the 1 outer spraying of steel pipe matrix can carry out the bilayer protection to steel pipe matrix 1, thereby can significantly strengthen the antiseptic effect of steel pipe, are particularly suitable for long distances heavy stickiness crude oil, fuel oil or natural gas etc.
