Discover the versatility of our metal pipes, available in varying thicknesses of 0.8mm, 1.0mm, and 1.2mm. These 25mm diameter galvanized pipes boast a lustrous chrome-plated finish, crafted from high-quality steel, and present a sleek and modern silver iron round design, perfect for various industrial and construction needs.
Our galvanized welded steel pipes, featuring hot-dip galvanization, are indispensable across a multitude of industries. From robust construction projects and sophisticated machinery to the demanding environments of coal mines and chemical plants, these pipes ensure reliability and longevity. They are also a staple in electric power systems, railway vehicles, the automotive sector, and infrastructure builds like highways, bridges, and containers. Furthermore, they serve essential roles in sports facilities, agricultural and petroleum machinery, and innovative solutions for greenhouse construction, among other manufacturing industries.
Galvanized steel pipes are a marvel of engineering, featuring a protective hot-dip or electro-galvanized layer that significantly boosts their corrosion resistance and extends their service life. These versatile pipes are widely utilized not only as conduits for low-pressure fluids such as water, gas, and oil but also as essential components in the petroleum industry, including oil well pipes and offshore oil field operations. They are critical in chemical coking equipment, serving as oil heaters and condensers, and find applications in coolers, coal distillation washing oil exchangers, and structural supports like trestle piles and mining tunnel frames.
Hot-dip galvanized pipes are crafted through a meticulous process where molten metal interacts with the iron matrix, forming a robust alloy layer that melds seamlessly with the steel substrate. The process begins with pickling the steel to eradicate surface impurities, followed by immersion in ammonium chloride or zinc chloride solutions before a final hot dip. This results in a pipe with a uniformly applied coating that boasts strong adhesion and extended durability. The intricate physical and chemical reactions during this process yield a compact, corrosion-resistant zinc-iron alloy layer, firmly bonded to both the pure zinc layer and the steel substrate, offering unparalleled corrosion resistance.
Cold galvanized pipes, or electro-galvanized pipes, carry a minimal zinc coating of merely 10-50g/m2, resulting in significantly reduced corrosion resistance compared to their hot-dip counterparts. Due to quality concerns, reputable manufacturers avoid electro-galvanizing, typically left to smaller firms with outdated technology, which in turn, offer cheaper products. The Ministry of Construction has mandated the phasing out of these technologically inferior cold galvanized pipes, prohibiting their use in water and gas pipelines. The electroplated zinc layer in cold galvanized pipes is thin and separate from the steel substrate, making it prone to detachment and thus less effective against corrosion.
Efficient Rust Removal Techniques
(1). Begin by employing a solvent to meticulously cleanse the steel surface, effectively removing any organic material and preparing the surface for further treatment.
(2). Follow with mechanical rust removal using tools such as a wire brush to detach loose or inclined scale, rust, welding slag, and other surface imperfections, ensuring a clean and smooth finish.
(3). Conclude with the pickling method for thorough cleansing and rust removal, enhancing the surface's readiness for subsequent coating or painting.
Galvanizing comes in two forms: hot-dip and cold-dip. Hot-dip galvanizing provides superior rust resistance, making it the preferred choice for long-term durability, whereas cold-dip galvanizing, being more susceptible to corrosion, is less favorable for enduring applications.
