Discover exceptional quality with our meticulously crafted 0.8mm, 1.0mm, and 1.2mm thickness metal pipes. These 25mm diameter galvanized pipes boast superior chrome plating, offering a sleek silver iron finish. Perfectly rounded and robust, they are the ideal choice for your construction needs.
Our galvanized welded steel pipes represent the pinnacle of durability and versatility. These hot-dip galvanized steel pipes are extensively utilized across a multitude of sectors, including construction, machinery, coal mining, chemical industries, electric power, railway vehicles, automotive industry, highways, bridges, container manufacturing, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery. Additionally, they play a vital role in greenhouse construction and various other manufacturing industries.
Steel pipes with galvanized coating are the backbone of pipeline technology. These welded steel pipes, enveloped with either a hot-dip or electro-galvanized layer, exhibit remarkable corrosion resistance, significantly extending their lifespan. Their applications are vast and varied, ranging from pipeline conduits for water, gas, and oil to integral components in petroleum industries as oil well and transport pipes. They are indispensable in offshore oil fields and function as oil heaters and condensers in chemical coking equipment. Furthermore, they serve as essential parts in coolers, coal distillation washing oil exchangers, as well as structural supports for trestle piles and mine tunnels.
Hot-dip galvanizing is an advanced method ensuring the durability of steel pipes. This process involves a chemical reaction between molten metal and the iron matrix, resulting in a tightly bound alloy layer. Initially, steel pipes undergo pickling to remove surface iron oxide. They are then immersed in an ammonium or zinc chloride solution before being hot-dipped. This technique guarantees a uniform coating with strong adhesion, creating a robust zinc-iron alloy layer that seamlessly integrates with the pure zinc and steel pipe substrate, offering unparalleled corrosion resistance.
Cold galvanized pipes, known for their electro-galvanized coating, exhibit a significantly lower zinc content, ranging from 10-50g/m2. Consequently, their corrosion resistance is markedly inferior to that of hot-dip galvanized pipes. Reputable manufacturers have largely abandoned this method due to its outdated technology and subpar performance. The Ministry of Construction has mandated the phasing out of cold galvanized pipes, especially for water and gas applications, due to their weak zinc-plating layer that tends to easily detach from the steel substrate, compromising its integrity.
Effective Rust Removal Techniques
(1). Begin by utilizing solvents to cleanse the steel surface, effectively stripping away any organic materials.
(2). Next, employ mechanical tools such as wire brushes to meticulously remove any loose rust, scale, or welding slag, ensuring a clean surface.
(3). Conclude the process with pickling, a proven method for thorough rust removal and preparation of the steel for further processing.
Galvanizing is categorized into two distinct processes: hot-dip and cold-dip. Hot-dip galvanizing is renowned for its superior rust resistance, while cold-dip galvanizing is more prone to rust.
