Discover the slim yet robust choice of steel perfection: our metal pipes, available in 0.8mm, 1.0mm, and 1.2mm thickness. With a precise 25mm diameter, these galvanized pipes boast a chrome-plated, silver iron finish, creating a stunning, round steel tube ideal for diverse applications.
Our galvanized welded steel pipes are the backbone of a myriad of industries, from construction to machinery, and beyond. The hot-dip process imbues these pipes with exceptional resilience, making them indispensable across sectors such as coal mining, chemical processing, and electric power. Whether in the automobile industry, on highways, bridges, or within sports facilities, our pipes ensure structural integrity and durability. Furthermore, they serve critical roles in agricultural machinery, petroleum equipment, and even greenhouse construction, standing as a testament to their versatility and strength.
Galvanized steel pipes represent the pinnacle of durability, featuring a welded construction enveloped in a protective hot-dip or electro-galvanized coating. This galvanization elevates the pipes' resistance to corrosion, significantly extending their lifespan. Versatile in application, these pipes confidently channel low-pressure fluids like water, gas, and oil, while also finding specialized uses in the petroleum industry as oil well and pipeline conduits, particularly offshore. They're also key components in chemical coking equipment, oil heaters, and condensers. Across industries from coal distillation to mining support frames, these pipes are indispensable, underpinning operations with unparalleled reliability and efficacy.
The hot-dip galvanized pipe is a marvel of metallurgical innovation, where molten metal melds with the iron matrix to spawn an alloy layer, fusing foundation and coating seamlessly. This process starts with pickling the steel to eradicate iron oxides, followed by immersion in ammonium chloride or zinc chloride solutions, before entering the molten dip bath. The result is a pipe with a uniformly applied, strongly adhesive, and enduring coating. Through intricate physical and chemical reactions, the zinc-iron alloy materializes, forming a dense, corrosion-resistant barrier integrated with the pure zinc layer and the steel substrate, ensuring formidable protection and longevity.
Cold galvanized pipes, known for their electro-galvanized finish, exhibit minimal coating—ranging from just 10 to 50g/m2. Their corrosion resistance pales in comparison to their hot-dip counterparts. As a result, leading manufacturers have transitioned away from this outdated technology, leaving it to smaller enterprises with antiquated processes seeking cost advantages. The Ministry of Construction has mandated the phase-out of these pipes for water and gas applications, emphasizing their inferior quality. The electroplated zinc layer in cold galvanized pipes lies independently from the steel substrate, easily detaching and offering scant protection against corrosion.
Effective Rust Removal Techniques for Steel Surfaces
(1). Initiate the rust removal process by utilizing solvents to meticulously cleanse the steel surface, effectively stripping away any organic contaminants that could jeopardize the integrity of the material.
(2). Follow up with mechanical rust removal techniques, such as wire brushing, to efficiently eradicate loose or sloped scale, rust, welding residue, and other surface blemishes, ensuring a pristine metal surface.
(3). Employ the pickling method as a final step, to ensure a thorough removal of any remaining rust and impurities, preparing the steel for further processing or coating.
In the realm of galvanization, differentiation between hot-dip and cold-dip processes is crucial: hot-dip galvanization provides superior resistance to rust, whereas cold-dip galvanization offers lesser protection, making it more prone to corrosion over time.
