The utility model is characterized in that a hydroxyamino rubber modified bitumen layer (2) and a polyethylene protective layer (3) are sequentially arranged outside a steel pipe (1). The hydroxyamino rubber modified bitumen anti-corrosion pipe has the advantages of good shock resistance performance, little possibility of embrittlement cracking or falling-off and long service life.

Description

Hydroxyl ammonia rubber modified asphalt anticorrosion pipe

Technical field:

The utility model relates to a steel pipe used for liquid or gas in the field of oil recovery in an oil field, which belongs to the hydroxyl ammonia rubber modified asphalt anticorrosion pipe.

Background technique:

Steel pipes are used to transport liquids during oil production. Corrosion and perforation will occur in long-term use of steel pipes, which will cause the steel pipes to be unusable before their service life is reached. However, due to structural reasons, the anticorrosion of steel pipes currently used in the field has the problems of poor impact resistance, brittle cracking and falling off, short service life and high production costs, which affect the anticorrosion effect of steel pipes.

Utility model content:

In order to solve the problems of poor anti-corrosion and impact resistance of existing steel pipes, easy brittle cracking and falling off, and short service life, the utility model provides a hydroxyl ammonia rubber modified asphalt anti-corrosion pipe. The hydroxyl ammonia rubber modified asphalt anti-corrosion pipe has good impact resistance , not easy to break and fall off, and has the characteristics of long service life.

The technical scheme adopted by the utility model is: the hydroxyl ammonia rubber modified asphalt anticorrosion pipe includes a steel pipe, and the steel pipe is successively provided with a hydroxyl ammonia rubber modified asphalt layer and a polyethylene protective layer.

The beneficial effects of the utility model are: the hydroxyl ammonia rubber modified asphalt anticorrosion pipe adopts the above scheme, the hydroxyl ammonia rubber modified asphalt layer and the steel pipe have high adhesion and strong adhesion, and are protected by a polyethylene protective layer. , with good impact resistance, not easy to break and fall off, long service life, high mechanical strength and corrosion resistance; the surface of the pipe is bright and smooth, without pinholes. Therefore, the hydroxyl ammonia rubber modified asphalt anticorrosion pipe has the characteristics of good impact resistance, not easy to be brittle and broken, and has a long service life.

Description of drawings:

Accompanying drawing 1 is a structural sectional view of the utility model.

1-steel pipe, 2-hydroxylamine rubber modified asphalt layer, 3-polyethylene protective layer.

Detailed ways:

The utility model will be further described below in conjunction with accompanying drawing:

As shown in Figure 1, the hydroxyl ammonia rubber modified asphalt anticorrosion pipe includes a steel pipe 1, and the steel pipe 1 has a hydroxyl ammonia rubber modified asphalt layer 2 and a polyethylene protective layer 3, and the hydroxyl ammonia rubber modified asphalt layer 2 Extrude negative pressure through the circular die of the extruder to coat the outer surface of the steel pipe 1 and the polyethylene protective layer 3, and the polyethylene protective layer 3 and the hydroxyl ammonia rubber modified asphalt layer 2 are closely bonded together, A reliable anti-corrosion effect and a long service life are formed, and at the same time, the difficulty of production and processing is reduced, the pollution to the environment is reduced, and the production cost is reduced.

In actual use, since the hydroxyl ammonia rubber modified asphalt layer 2 is used as a modified material, the anticorrosion, bonding, and load-bearing properties of the anti-corrosion layer are improved. The hydroxyl ammonia rubber modified asphalt layer 2 is mixed with solids and extruded Extrusion circular die extrusion negative pressure coating on the surface of the steel pipe 1 to form the hydroxyl ammonia rubber modified asphalt layer 2, at the same time, under high temperature, the polyethylene protective layer 3 on the outer surface of the hydroxyl ammonia rubber modified asphalt layer 2 anti-corrosion layer , the two are closely bonded together to form a reliable anti-corrosion layer structure. The hydroxyl ammonia rubber modified asphalt anti-corrosion pipe has excellent anti-corrosion performance and anti-damage performance. In addition, the overall anti-corrosion layer is black, which improves the resistance to external radiation and aging, and greatly improves the service life.

The hydroxyl ammonia rubber modified asphalt anticorrosion pipe has good corrosion resistance, good impact resistance, is not easy to be brittle and falls off, and has a long service life, and can ensure that the outer surface will not be delaminated or fall off during construction and transportation; the main Applied to oil, gas and water pipelines in oil fields.
