Introducing our premier selection of Hot Dipped Galvanized Round Pipes, available in thicknesses of 0.8mm, 1.0mm, and 1.2mm, and boasting a sleek 25mm diameter. These pipes are crafted from chrome plating steel and finished in a dazzling silver, making them not just practical but also visually appealing for your construction needs.
Our high-quality galvanized welded steel pipes are a cornerstone in a multitude of industries, including construction, machinery, and beyond. With a robust hot-dip galvanized finish, these pipes deliver unparalleled durability and are integral in sectors such as coal mining, chemical processing, electric power, railway vehicles, the automotive industry, highways, and bridge construction. They also serve in containers, sports facilities, agricultural machinery, petroleum and prospecting machinery, greenhouse construction, and other manufacturing spheres.
Experience the superior advantages of galvanized steel pipes, known for their resilient hot-dip or electro-galvanized layer, which significantly enhances corrosion resistance and extends service life. Versatile in application, these pipes are essential for low-pressure fluid transportation such as water, gas, and oil, and are indispensable in the petroleum industry for oil wells, especially offshore oil fields, and in chemical coking equipment as heaters and condensers. They are also crucial in coolers, coal distillation washing oil exchangers, and serve as support structures for mine tunnels and trestle piles.
The process of hot-dip galvanizing involves a transformative reaction between molten metal and an iron matrix, creating a robust alloy layer. This seamless integration between the matrix and the coating ensures a durable and long-lasting finish. Hot-dip galvanizing begins with pickling the steel pipe to eliminate surface iron oxide, followed by immersion in a cleaning solution before dipping into the molten bath. This method offers uniform coating, strong adhesion, and an extended lifespan. The resulting zinc-iron alloy layer is corrosion-resistant and intricately bonded with both the zinc layer and steel pipe substrate.
Cold galvanizing, or electro-galvanization, involves a minimal zinc application ranging from 10-50g/m2, resulting in significantly lesser corrosion resistance compared to hot-dip galvanizing. Notably, most reputable manufacturers avoid this method due to its inferior quality and adherence issues. The Ministry of Construction has mandated the phase-out of outdated cold galvanizing technology for water and gas pipes. The electroplated zinc layer in cold galvanization lacks bond strength and can easily detach, leading to poorer protection against corrosion.
Methods for Effective Rust Removal
(1). Begin by applying a solvent to thoroughly cleanse the steel surface, effectively eliminating any organic contaminants.
(2). Follow up with mechanical rust removal using tools such as wire brushes. This step is crucial for dislodging loose scale, rust, and welding slag.
(3). Proceed with the pickling method to ensure optimal surface preparation.
Galvanizing is categorized into hot-dip and cold-dip processes. Hot-dip galvanizing offers superior rust resistance, whereas cold-dip galvanizing is prone to quicker rusting.
