Title:
ULTRA-STRONG THIN-WALLED CORROSION-RESISTANT STEEL PIPE
Document Type and Number:
WIPO Patent Application WO/2022/257880
Kind Code:
A1
Abstract:
An ultra-strong thin-walled corrosion-resistant steel pipe. The steel pipe 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 in order from the outside to the 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 has good mechanical properties, a long service life, is strong and lightweight, and can facilitate the erection of scaffolding at a high altitude, thereby reducing construction risks.
