Introducing our premium range of galvanized steel pipes, available in diverse thickness options of 0.8mm, 1.0mm, and 1.2mm. These pipes boast a sturdy 25mm diameter, are expertly chrome-plated, and crafted from high-quality silver iron. Perfectly round and robust, these pipes are engineered for resilience and durability.
Our galvanized welded steel pipes, featuring superior hot-dip galvanization, are meticulously designed to meet diverse industrial demands. From construction and machinery to coal mining and chemical industries, these pipes are integral to sectors like electric power, railway vehicles, and automotive. They are also indispensable in infrastructure projects, including highways, bridges, and containers, while serving crucial roles in sports facilities, agricultural and petroleum machinery, exploratory equipment, and greenhouse construction.
Galvanized steel pipes are a hallmark of reliability, crafted with a protective hot-dip or electro-galvanized layer. This galvanization process significantly enhances corrosion resistance, ensuring longevity. Widely versatile, these pipes are ideal for general low-pressure fluid pipelines like water, gas, and oil. In the petroleum industry, they serve as essential oil well and oil pipes, especially offshore, and are vital in chemical coking equipment such as oil heaters and condensers. They also support cooling systems, coal distillation exchangers, trestle piles, and provide structural support in mine tunnels.
Hot-dip galvanized pipes are engineered through a meticulous process where molten metal forms an alloy layer by reacting with the iron matrix, ensuring a seamless bond between the coating and the substrate. Initially, the steel pipe undergoes pickling to eliminate iron oxide, followed by cleaning in a mixed aqueous solution of ammonium chloride and zinc chloride before immersion in a hot dip bath. This technique ensures a uniform coating, robust adhesion, and extended service life. The resultant zinc-iron alloy layer is compact and integrated with the pure zinc and steel substrate, offering unparalleled corrosion resistance.
Cold galvanized pipes utilize an electro-galvanization process, applying a minimal zinc coating (10-50g/m2) which results in less effective corrosion resistance compared to hot-dip galvanized pipes. Top manufacturers typically avoid electro-galvanization, as it is predominantly used by smaller enterprises with outdated equipment, offering lower-cost options. The Ministry of Construction has mandated the phasing out of obsolete cold galvanized pipes, particularly for water and gas applications. These pipes have a thin, weakly adhered zinc layer that is prone to detachment, leading to poor corrosion resistance.
Effective Rust Removal Techniques
(1). Initiate the process by applying a solvent to the steel surface, efficiently removing any organic contaminants.
(2). Employ mechanical tools, such as wire brushes, to meticulously eliminate loose or angled scale, rust, and welding residues.
(3). Conclude with the pickling method for comprehensive rust removal.
Galvanizing processes are categorized into hot-dip and cold-dip methods. Hot-dip galvanization is renowned for its superior resistance to rust, whereas cold-dip galvanization is more susceptible to corrosion.
