Explore our versatile range of galvanized steel tubes, featuring various thickness options including 0.8mm, 1.0mm, and 1.2mm. These tubes boast a 25mm diameter, are chrome-plated, and come in a sleek silver finish. Ideal for numerous applications, our round metal pipes are engineered for strength and durability.
Our premium galvanized welded steel pipes are hot-dip galvanized and serve a multitude of industries. From construction and machinery to coal mining, chemical processing, and more, our robust pipes are perfect for electric power, railway vehicles, automotive industries, and beyond. They are also a reliable choice for highways, bridges, containers, sports facilities, agriculture, petroleum machinery, and greenhouse construction.
Our galvanized steel pipes, outfitted with either a hot-dip or electro-galvanized layer, significantly boost corrosion resistance and extend service life. Beyond their role as pipeline conduits for water, gas, and oil, these versatile pipes are crucial in the petroleum industry, particularly offshore oil fields. They serve as oil well pipes, oil heaters, and condensers in chemical coking equipment, cooling systems, coal distillation washing oil exchangers, and are foundational in trestle piles and mine tunnel supports.
The hot-dip galvanizing process involves immersing steel pipes in molten metal to form a durable alloy layer that fuses the coating with the matrix. This method ensures a uniform coat, robust adhesion, and extended service life. As the substrate engages in intricate physical and chemical interactions with the molten zinc, it forms a tightly integrated, corrosion-resistant zinc-iron alloy layer. This layer, combined with the pure zinc coating and the steel pipe substrate, delivers formidable corrosion resistance.
Cold-galvanized pipes, or electro-galvanized pipes, feature minimal zinc coating (10-50g/m2), offering significantly less corrosion resistance compared to hot-dip counterparts. Established manufacturers prioritize hot-dip methods, as electro-galvanizing is mainly employed by smaller enterprises due to outdated technology, resulting in lower costs but inferior quality. The Ministry of Construction mandates eliminating outdated cold-galvanized pipes, particularly for water and gas applications, as their thin zinc layer easily detaches, compromising durability.
Methods for Effective Rust Removal
(1). Begin by using a solvent to cleanse the steel's surface, effectively removing any organic contaminants.
(2). Next, employ tools such as wire brushes to eliminate rust, loose scales, welding slag, and other residues.
(3). Apply the pickling method for thorough rust removal.
Galvanization options include hot-dip and cold-dip methods. Hot-dip galvanization offers superior rust resistance, while cold-dip is more susceptible to corrosion.
