Experience the robust and versatile craftsmanship of our galvanized steel tubes, available in precise thicknesses of 0.8mm, 1.0mm, and 1.2mm. Featuring a 25mm diameter, these chrome-plated steel tubes stand out with their striking silver finish, perfect for a range of applications requiring round, iron-based pipe structures.
Our galvanized welded steel pipes, particularly those enhanced through hot-dip galvanization, are the top choice across various industries. From the sturdy frameworks of construction and the precision demands of machinery to the resilient requirements of coal mining and chemical processing, our pipes excel. They play crucial roles in powering electric grids, forming the backbone of railway vehicles, and underpinning the automotive industry. Whether it's highways, bridges, containers, sports facilities, or agricultural machinery, these pipes meet diverse needs. Trusted in petroleum machinery, prospecting machinery, and fostering greenhouse construction, our products are indispensable across the manufacturing landscape.
The galvanized steel pipe is a marvel of modern engineering, boasting a welded structure enveloped in a protective hot-dip or electro-galvanized layer. This galvanization exponentially boosts its resistance to corrosion, thereby extending its service life. Its versatility finds it used in pipelines for low-pressure fluids-be it water, gas, or oil. Notably, it is indispensable in the petroleum industry, serving as oil well and oil pipes, especially in challenging offshore oil fields. In the realm of chemical coking equipment, it functions as oil heaters and condensers. Additionally, it plays a pivotal role in the cooling systems of coal distillation, acts as trestle piles, and supports mine tunnels.
Hot-dip galvanized pipes embody a fusion of molten metal and iron matrix, creating a durable alloy layer that intimately bonds the matrix and coating. Through a meticulous process, the steel pipe undergoes pickling to cleanse surface iron oxides, followed by a treatment in ammonium chloride or zinc chloride solutions, culminating in a hot dip bath. This results in a uniform, tightly adhered coating that ensures longevity. The physical and chemical reactions during this process forge a zinc-iron alloy layer, endowing the pipe with formidable corrosion resistance-a hallmark of strong, enduring steel pipe solutions.
Cold-galvanized pipes, characterized by their electro-galvanization, feature a minimal zinc coating of just 10-50g/m². This sparse layer significantly compromises corrosion resistance compared to their hot-dip counterparts. Consequently, reputable manufacturers have phased out electro-galvanization in favor of more advanced techniques. The Ministry of Construction has mandated discontinuing the use of cold-galvanized pipes for water and gas due to their inferior quality. The electroplated zinc layer is thin, merely adhering to the steel substrate, rendering it prone to peeling and, therefore, inadequate for resisting corrosion effectively.
Comprehensive Rust Removal Methodology
(1). Begin with a thorough solvent clean to eradicate surface-level organic contaminants on the steel.
(2). Proceed with mechanical rust removal using wire brushes to dislodge loose scales, rust, and welding slag, ensuring a clean substrate.
(3). Complete the rust removal process with an effective pickling treatment.
Galvanization Processes: Hot-dip vs. Cold-dip. Hot-dip ensures robust rust resistance, while cold-dip, being more susceptible to rust, is less favored in durability-focused applications.
