Unlock the potential of our exceptional metal pipes, offered with thickness options of 0.8mm, 1.0mm, and 1.2mm. These 25mm diameter galvanized pipes are adorned with a brilliant chrome-plated finish, crafted from premium-grade steel. Their sleek and contemporary silver iron round design makes them an ideal choice for diverse industrial and construction applications, ensuring both functionality and aesthetic appeal.
Our galvanized welded steel pipes, distinguished by their hot-dip galvanization process, are vital across numerous industries. From sturdy construction projects and advanced machinery to the demanding settings of coal mines and chemical plants, these pipes guarantee unwavering reliability and prolonged service life. They are indispensable in electric power systems, railway vehicles, automotive manufacture, and infrastructure projects like highways, bridges, and containers. Additionally, they play crucial roles in sports facilities, agricultural and petroleum machinery, and pioneering greenhouse construction solutions, among various other manufacturing sectors.
Galvanized steel pipes represent a pinnacle of engineering excellence. With a protective hot-dip or electro-galvanized layer, they achieve remarkable corrosion resistance and extended service life. These versatile pipes are extensively used not only as conduits for low-pressure fluids such as water, gas, and oil but also as vital components in the petroleum industry, including oil well pipes and offshore oil field operations. They are indispensable in chemical coking equipment, functioning as oil heaters and condensers, and find applications in coolers, coal distillation washing oil exchangers, and as structural supports like trestle piles and mining tunnel frames.
Hot-dip galvanized pipes are meticulously crafted through a sophisticated process where molten metal interacts with the iron matrix to form a robust alloy layer that integrally bonds with the steel substrate. This process begins with pickling the steel to remove surface impurities, followed by immersion in ammonium chloride or zinc chloride solutions before a final hot dip. The result is a pipe with a uniformly applied coating, demonstrating strong adhesion and extended durability. The complex physical and chemical reactions during this process create a compact, corrosion-resistant zinc-iron alloy layer, firmly bonded to both the pure zinc layer and the steel substrate, offering unmatched corrosion resistance.
Cold galvanized pipes, also known as electro-galvanized pipes, possess a minimal zinc coating of just 10-50g/m2, resulting in notably reduced corrosion resistance compared to their hot-dip counterparts. Due to quality concerns, reputable manufacturers steer clear of electro-galvanizing, a practice typically relegated to smaller firms with outdated technology, leading to cheaper products. The Ministry of Construction has mandated the elimination of these technologically inferior cold galvanized pipes, banning their use in water and gas pipelines. The electroplated zinc layer in cold galvanized pipes is thin and separate from the steel substrate, resulting in a tendency to detach and thus offering inadequate protection against corrosion.
Advanced Rust Removal Techniques
(1). Start with a solvent to thoroughly cleanse the steel surface, efficiently removing any organic material and priming the surface for subsequent treatments.
(2). Proceed with mechanical rust removal using tools like a wire brush to dislodge loose or inclined scale, rust, welding slag, and other surface imperfections, ensuring a pristine and smooth finish.
(3). Complete the process with the pickling method for comprehensive cleansing and rust removal, enhancing the surface's readiness for further coating or painting.
Galvanizing is available in two forms: hot-dip and cold-dip. Hot-dip galvanizing offers superior rust resistance, making it the ideal choice for long-term durability, while cold-dip galvanizing, being more vulnerable to corrosion, is less suitable for long-lasting applications.
