Abstract
The invention discloses a light aluminum alloy pipe which comprises an aluminum alloy outer layer and a plastic inner layer. The aluminum alloy outer layer and the plastic inner layer are combined together through prestressing force and manufactured into the aluminum alloy pipe through a seamless extrusion forming process. The aluminum alloy outer layer is made of light aluminum-magnesium alloy material which comprises, by mass, 5% to 10% of magnesium, 0.5% to 1% of copper, 0.2 % to 0.8% of nickel, 0.2% to 0.5% of manganese, 0.1% to 0.5% of iron, 0.4% to 0.8% of chromium and the balance aluminum and inevitable impurities. The plastic inner layer is made of thermoplastic PP-R plastic. In this way, the dual-layer combination structure is adopted, and the aluminum alloy pipe is formed by combining the aluminum alloy outer layer and the thermoplastic plastic inner layer through prestressing force, has the advantages of being resistant to corrosion, high in rigidity and strength and resistant to impact, and meanwhile has the advantages of being light in weight, easy to prepare and low in cost.
Description
Technical field
The present invention relates to alloy pipe field, particularly relate to a kind of light aluminum alloy pipe.
Background technique
Along with expanding economy, the raising of living standards of the people, energy demand is in continuous growth, and oil, rock gas will be occupied an leading position in world's primary energy structure of consumer demand.I crosses and is in the medium exploration phase by land at present, and old filed is in exploitation middle and advanced stage, and rock gas is in the early stage exploration phase, and Exploration Potential is large, and reserves increase fast.
When drilling oil, rock gas, except needs boring mechanic equipment, also need special tubing, namely drill string, sleeve pipe, oil pipe etc., be referred to as " oil well pipe ".According to the particularity of China's oil-gas mining environment, expert thinks, superhigh strength tubing and casing, high collapse strength, anti-acid environment corrosion oil pipe and special screw-threaded oil well pipes are the current and following Superior Oil Country Tubular Goods be badly in need of of China.At present, domestic Superior Oil Country Tubular Goods all dependence on import substantially production is substantially blank.Therefore, imperative at my excessive forces exploitation Superior Oil Country Tubular Goods.
Long-term dependence, oil well pipe selection mainly contains 13Cr, 22Cr, 25Cr, 316 stainless steels etc., and this several stainless steel intensity is higher, simultaneously containing higher Cr content, easily forms the Cr of one deck densification at alloy surface
2o
3passivating film, is highly resistant to CO
2corrosion, and along with the increase of Cr content, anti-CO
2the ability of corrosion strengthens gradually.But along with burying discovery gradually and the exploitation of very dark peracidity oil gas field, H in mining environment
2s
2, CO
2, S, Cl content is very high, conventional stainless steel pipe cannot meet exploitation requirement.Therefore, present stage oil well pipe material mainly adopt the abros of high-alloying, but abros oil well pipe manufacturing process is complicated, production difficulty is large and cost is higher.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of light aluminum alloy pipe, adopt two-layer composite, be composited through prestressing force by aluminum alloy skin and thermoplastic internal layer, have corrosion-resistant, hardness is high, intensity good, impact-resistant advantage, has the feature that quality is light, preparation is simple, cost is low simultaneously.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: provide a kind of light aluminum alloy pipe, comprise: aluminum alloy skin and inner plastic, described aluminum alloy skin and inner plastic are combined with each other through prestressing force, then make Al-alloy pipe through seamless extrusion moulding process; Described aluminum alloy skin adopts lightweight aluminium magnesium alloy materials, the mass percent of the raw material components that described lightweight aluminium magnesium alloy materials comprises and each component is: magnesium: 5%-10%, copper: 0.5%-1%, nickel: 0.2%-0.8%, manganese: 0.2%-0.5%, iron: 0.1%-0.5%, chromium: 0.4%-0.8%, and all the other are aluminium and inevitable impurity; Described inner plastic adopts thermoplasticity PP-R plastics.
In a preferred embodiment of the present invention, the outer field thickness of described aluminum alloy is 0.5-1mm.
