Problems solved by technology

But its anti-corrosion layer is thin and uneven, and the fastness is poor, the anti-corrosion effect is not very good, and the service life is still short
However, the cost of stainless steel profiles is too high, and their mechanical properties are poor, so they are not suitable for large-scale promotion.

specific Embodiment

[0018] Such as figure 1 As shown, it is a specific embodiment of the present invention: a super strong and thin-walled corrosion-resistant steel pipe, the steel pipe is sequentially composed of the first alloy layer 1, the second alloy layer 2, the third alloy layer 3, the The body 4 , the third alloy layer 3 , the second alloy layer 2 and the first alloy layer 1 .

[0019] Wherein, the first alloy layer 1 is a zinc alloy layer or a zinc oxide alloy layer; the second alloy layer 2 is a zinc-aluminum alloy layer or a zinc-aluminum-magnesium alloy layer; the third alloy layer 3 is a zinc-aluminum-iron alloy layer , zinc-aluminum-magnesium-iron alloy layer, aluminum-iron-alloy layer or aluminum-magnesium-iron alloy layer; the steel pipe body 4 is low-alloy structural steel. The thicknesses of the first alloy layer 1 , the second alloy layer 2 and the third alloy layer 3 are respectively 0.01-0.2 mm; the thickness of the steel pipe body 4 is 1.0-1.8 mm.

[0020] As a preferred e...

Abstract

The invention discloses a super-strong thin-walled corrosion-resistant steel pipe. The steel pipe sequentially comprises a first alloy layer, a second alloy layer, a third alloy layer, a steel pipe body, the third alloy layer, the second alloy layer and the first alloy layer from outside to inside. The first alloy layer is a zinc alloy layer or a zinc oxide alloy layer; the second alloy layer is a zinc-aluminum alloy layer or a zinc-aluminum-magnesium alloy layer; and the third alloy layer is one of a zinc-aluminum-iron alloy layer, a zinc-aluminum-magnesium-iron alloy layer, an aluminum-iron alloy layer or an aluminum-magnesium-iron alloy layer. The steel pipe provided by the invention has the advantages of good mechanical property, long service life, high strength and light weight, is convenient for erecting a scaffold at high altitude, and reduces the construction risk.

Description

technical field [0001] The invention relates to the technical field of steel pipes, in particular to a super-strong and thin-walled corrosion-resistant steel pipe. Background technique [0002] The existing steel pipes, especially the steel pipes used for scaffolding, generally do not have the surface of the steel pipes treated, are easy to corrode, and have a short service life. In order to improve the anti-corrosion ability and prolong the service life, electroplating, plastic spraying or painting are often used to form a thinner anti-corrosion layer on the surface of the steel pipe. However, its anti-corrosion layer is thin and uneven, and its fastness is poor, the anti-corrosion effect is not very good, and its service life is still short. However, the cost of stainless steel profiles is too high, and their mechanical properties are poor, so they are not suitable for large-scale promotion. Contents of the invention [0003] Aiming at the deficiencies of the prior art...
