Discover the excellence of our metal pipes, available in versatile thickness options of 0.8mm, 1.0mm, and 1.2mm. Engineered with precision, these 25mm diameter galvanized pipes boast chrome plating, exuding a stunning silver finish. Perfectly crafted, these round iron tubes are an ideal choice for those seeking both durability and style in their construction projects.
Our galvanized welded steel pipes are the epitome of versatility and reliability. The hot-dip galvanized finish ensures robustness, making them indispensable across numerous sectors. Whether you are in construction, machinery, coal mining, chemicals, or any other industry, these pipes are built to perform. From electric power systems to railway vehicles, the automobile industry, highways, bridges, and even sporting facilities, our steel pipes meet all demands. They are also pivotal in agricultural, petroleum, prospecting machinery, container manufacturing, and greenhouse construction. Rely on our galvanized steel pipes for unmatched performance in every manufacturing industry.
Galvanized steel pipes are the backbone of modern infrastructure, featuring a welded design with a protective hot-dip or electro-galvanized layer. This galvanization significantly enhances the corrosion resistance, extending the service life of the pipes. These pipes flourish in a multitude of applications: as low-pressure fluid conduits for water, gas, and oil, and specially in the petroleum industry as oil well piping. Offshore oil fields depend on them, as do chemical coking equipment for oil heating and condensers. They are essential in cooling systems, coal distillation oil exchangers, trestle pile construction, and framework for mine tunnels, proving their versatility and reliability.
Hot-dip galvanized pipes are crafted through an intricate process where molten metal interacts with iron matrices to form a robust alloy layer. This process ensures a harmonized bond between the matrix and coating. Initially, the pipes undergo pickling to strip away iron oxide, followed by a meticulous cleaning in an ammonium chloride or zinc chloride solution. The subsequent immersion in a hot dip bath yields a coating that promises uniformity, robust adhesion, and an extended service life. The physical and chemical reactions create a compact, corrosion-resistant zinc-iron alloy layer, seamlessly fusing with the pure zinc coat and steel substrate for unparalleled corrosion resistance.
Cold galvanized pipes, known as electro-galvanized pipes, suffer from minimal galvanization, with only 10-50g/m² zinc coating, which compromises their corrosion resistance compared to hot-dip alternatives. Recognizing quality assurance, most reputable manufacturers avoid this outdated technique, relegating it to small enterprises with older equipment, resulting in lower costs. The Ministry of Construction has mandated the phasing out of cold galvanized pipes, particularly for water and gas applications. These pipes feature an electroplated zinc layer that is not integrated with the steel substrate, leading to a fragile coating that is prone to detachment, thus diminishing its protective properties.
Advanced Rust Removal Techniques
(1). Begin with a solvent wash to effectively cleanse the steel surface of any organic contaminants, ensuring thorough preparation for subsequent treatments.
(2). Employ mechanical tools such as wire brushes to meticulously eliminate rust, loose scales, and welding residues, preparing the surface for optimal adhesion.
(3). Utilize the pickling method to further enhance the rust removal process, setting the stage for superior surface treatment.
Galvanization comes in two types: hot-dip and cold-dip. Hot-dip offers superior rust resistance, while cold-dip tends to deteriorate more quickly, emphasizing the importance of choosing the right treatment for longevity.
