Abstract
The utility model discloses a composite steel pipe with an outer polyethylene layer and an inner epoxy resin layer, which comprises a steel tube basal body, an outer epoxy resin layer and the polyethylene layer are arranged sequentially from inside to outside on the outer surface of the steel tube basal body, an adhesive layer is arranged between the outer epoxy resin layer and the polyethylene layer, and the inner epoxy resin layer is arranged on the inner surface of the steel tube basal body. The composite steel pipe of the structure has excellent anti-corrosion capability and a good machine-protecting property, and the service life of the composite steel pipe can be greatly prolonged.
Description
Technical field
The utility model relates to epoxy coating composite steel tube in a kind of outer polyethylene.
Background technique
At present, the anti-corrosive steel tube of selling on the market, its outer surface scribbles anticorrosive coat, its internal surface generally do not have anticorrosive coat or adopt simply spray paint carry out anticorrosion.Because the adhesion of the inhomogeneous and enamelled coating that sprays paint is low, steel pipe in use, its internal surface antiseptic power is poor, corrodes easily and weares and teares, and causes reduce greatly the working life of steel pipe.
The model utility content
The technical problems to be solved in the utility model is at above-mentioned deficiency, and a kind of internal surface favorable anti-corrosion effect is provided, and the outer surface mechanical property is good, epoxy coating composite steel tube in the outer polyethylene of long service life.
In order to solve the problems of the technologies described above, the utility model provides a kind of outer polyethylene of following structure interior epoxy coating composite steel tube, comprise the steel pipe matrix, its structural feature is: from inside to outside be provided with outer epoxy resin layer and polyethylene layer on the outer surface of described steel pipe matrix successively, be provided with adhesive layer between outer epoxy resin layer and the polyethylene layer, the internal surface of steel pipe matrix is provided with interior epoxy resin layer.
Epoxy coating composite steel tube in the outer polyethylene of said structure, because internal surface is provided with interior epoxy resin layer, epoxy resin has good rotproofness and wear resistance, therefore, the corrosion protection abrasion resistant ability of steel pipe internal-surface is improved greatly; Again because its outer surface is provided with outer epoxy resin layer and polyethylene layer, outer epoxy resin layer and polyethylene layer link together firmly by adhesive layer between the two, interfacial characteristics and chemically-resistant characteristic with epoxy resin layer, fully combine with the good mechanical protection feature of polyethylene layer, therefore, make the outer surface of steel pipe not only have good corrosion resistant ability, but also have good mechanical protection performance; Under antiseptic power and mechanical protection performance all were further enhanced situation, also prolonged greatly naturally the working life of steel pipe.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model.
Embodiment
Epoxy coating composite steel tube in the outer as shown in drawings polyethylene, comprise steel pipe matrix 1, from inside to outside be provided with outer epoxy resin layer 2 and polyethylene layer 3 on the outer surface of described steel pipe matrix 1 successively, be provided with adhesive layer 4 between outer epoxy resin layer 2 and the polyethylene layer 3, the internal surface of steel pipe matrix 1 is provided with interior epoxy resin layer 5.
Claims (1)
1. epoxy coating composite steel tube in the outer polyethylene, comprise steel pipe matrix (1), it is characterized in that: from inside to outside be provided with outer epoxy resin layer (2) and polyethylene layer (3) on the outer surface of described steel pipe matrix (1) successively, be provided with adhesive layer (4) between outer epoxy resin layer (2) and the polyethylene layer (3), the internal surface of steel pipe matrix (1) is provided with interior epoxy resin layer (5).
