Experience the perfect blend of precision and durability with our metal tubes crafted to meet various thickness requirements: 0.8mm, 1.0mm, and 1.2mm. Our 25mm diameter galvanized pipes boast a sleek chrome-plated finish, offering a stunning silver hue in an iron round pipe that promises exceptional performance.
Our galvanized welded steel pipes define versatility and strength, making them indispensable across a multitude of industries. The hot-dip galvanized steel pipes lead the way in construction, machinery, and coal mining sectors, while finding pivotal roles in chemicals, electric power, and railway vehicle manufacturing. Their robust nature ensures reliability in the automobile industry, highways, and bridges. Beyond infrastructure, these pipes are essential in sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery, extending their utility to greenhouse construction and an array of manufacturing arenas.
Discover the unmatched resilience of galvanized steel pipes, expertly engineered as welded steel pipes with a protective hot-dip or electro-galvanized layer. This galvanization significantly bolsters corrosion resistance, ensuring longevity and durability. These versatile pipes excel as conduits for low-pressure fluids like water, gas, and oil and as critical components in the petroleum industry, notably offshore oil fields. They serve impeccably in oil heaters, condensers in chemical coking equipment, cooler pipes, and coal distillation washing oil exchangers, while also providing robust support as trestle piles and mine tunnel frameworks.
Hot-dip galvanized pipes embody synergy between molten metal and iron matrices, forming a robust alloy layer that unites the steel pipe's core with its coating. This process begins with thorough pickling to eradicate iron oxide, followed by immersion in ammonium chloride or zinc chloride solutions, culminating in a hot dip bath. The result is a coating that is uniformly applied, tenaciously adherent, and remarkably enduring. The hot-dip process fosters complex physical and chemical reactions producing a resilient zinc-iron alloy layer. This layer, seamlessly integrated with the pure zinc and steel substrate, fortifies the pipe against corrosion.
Cold galvanized pipes, characterized by electro-galvanized layers, offer only modest protection, with zinc coating ranging from 10-50g/m2. This process yields significantly reduced corrosion resistance compared to hot-dip galvanized pipes. Typically, reputable manufacturers avoid using electro-galvanizing due to its inferior longevity, often found in smaller enterprises with outdated technologies aiming for cost-efficiency. As a testament to improved standards, the Ministry of Construction has decreed the phase-out of cold galvanized pipes in water and gas applications. The electroplated zinc layer, lacking integration with the steel substrate, is prone to detachment, compromising its defensive capabilities.
Effective Rust Removal Techniques
(1). Begin by utilizing a solvent to thoroughly cleanse the steel surface, efficiently eliminating any organic residue or contaminants.
(2). Follow up with mechanical rust removal using a wire brush to meticulously strip away loose or angled scale, rust, welding slag, and similar impurities.
(3). Conclude with an acid-based pickling technique for comprehensive rust elimination.
The galvanization process is categorized into hot-dip and cold-dip methods. Hot-dip galvanizing offers superior rust prevention, while cold-dip galvanizing is more susceptible to rust development.
