Discover the remarkable qualities of our 0.8mm, 1.0mm, and 1.2mm thickness metal pipes featuring a 25mm galvanized pipe diameter. These chrome-plated steel tubes boast a striking silver finish, providing sleek and robust round pipes crafted from premium iron to meet diverse industrial needs.
Our galvanized welded steel pipes, featuring cutting-edge hot-dip galvanizing, are indispensable across a multitude of industries. From the robust infrastructure of construction sites to the innovative machinery in coal mines and chemical plants, these pipes serve as vital components in electric power systems, railway vehicles, and the automobile sector. Additionally, they hold a crucial role in the development of highways, bridges, containers, and sports facilities, while supporting the efficiency of agricultural machinery, petroleum exploration, and even greenhouse constructions.
Galvanized steel pipes are expertly engineered welded steel pipes, enveloped in a protective hot-dip or electro-galvanized layer, significantly boosting corrosion resistance and extending their lifespan. Beyond their primary function as conduits for low-pressure fluids like water, gas, and oil, these pipes find valuable applications in the petroleum sector as oil well and transport pipes, particularly in offshore fields. They are essential in chemical coking equipment, serving as oil heaters and condensers, and play a vital role in coolers, coal distillation washing oil exchangers, trestle piles, and mine tunnel support structures.
The hot-dip galvanizing process involves a transformative reaction between molten metal and the iron matrix, resulting in a durable alloy layer uniting the matrix and coating. Initially, steel pipes undergo pickling to remove surface iron oxide, followed by cleansing in an ammonium chloride or zinc chloride solution. Immersed in a hot dip bath, this method ensures uniform coating, robust adhesion, and prolonged service life. The metallurgical bond formed between the zinc-iron alloy layer and the pure zinc layer fortifies the steel pipe, rendering it exceptionally resistant to corrosion.
Cold galvanized pipes, known for their electro-galvanized finish, offer minimal zinc coating-ranging from 10-50g/m2-resulting in significantly lower corrosion resistance compared to their hot-dip counterparts. While some outdated enterprises may utilize electro-galvanizing for cost efficiency, leading manufacturers adhere to advanced standards, eschewing cold galvanization. In response, the Ministry of Construction has mandated the discontinuation of cold galvanized pipes, deeming them unsuitable for water and gas transport due to their fragile zinc layer, which simply adheres to the substrate and is prone to detachment.
Methods for Effective Rust Removal
(1). Begin by applying a solvent to meticulously clean the steel surface, effectively eliminating organic substances and preparing it for further treatment.
(2). Follow up with mechanical rust removal techniques, employing wire brushes to dislodge and clear away any loose or inclined scale, persistent rust, or welding slag.
(3). Conclude the process by utilizing a pickling method, ensuring thorough rust eradication and surface purification.
Galvanizing techniques are bifurcated into hot-dip and cold-dip methods. Hot-dip galvanizing is renowned for its superior rust resistance, while cold-dip galvanizing is more susceptible to corrosion.
