Experience the unparalleled strength and durability of our metal pipes, available in a variety of thicknesses-0.8mm, 1.0mm, and 1.2mm. The 25mm galvanized pipe diameter, complete with chrome plating, offers a sleek and sophisticated silver finish, ensuring that our round steel tubes are not only functional but also aesthetically pleasing. Ideal for a multitude of applications, our silver iron pipes are crafted to meet your highest standards.
Discover the versatility and reliability of our galvanized welded steel pipes. Our hot-dip galvanized steel pipes serve as the backbone for numerous industries, including construction, machinery, and more. Perfect for use in coal mines, chemicals, and electric power, they provide essential support for railway vehicles, the automobile industry, and infrastructure projects like highways and bridges. With applications extending to containers, sports facilities, agricultural equipment, and beyond, our steel pipes are integral to petroleum and prospecting machinery, greenhouse constructions, and a wide array of manufacturing industries.
Our galvanized steel pipes represent the pinnacle of durability and utility. With a robust hot-dip or electro-galvanized layer, these welded steel pipes boast enhanced corrosion resistance, significantly extending their lifespan. Beyond their role in transporting low-pressure fluids such as water, gas, and oil, they find critical applications in the petroleum industry as oil well and oil pipes, particularly in offshore oil fields. Additionally, they stand out in chemical coking equipment as oil heaters and condensers, and in coal distillation washing oil exchangers. They also serve as foundational elements for trestle piles and supporting structures in mine tunnels, showcasing their versatility and reliability.
Hot-dip galvanized pipes are engineered for superior performance with a unique process that combines molten metal with the iron matrix to form a resilient alloy layer. This meticulous procedure involves pickling to eliminate iron oxide, followed by cleansing in an ammonium chloride or zinc chloride aqueous solution, and culminating in a hot dip bath. The result is a uniformly coated pipe renowned for its strong adhesion and extended service life. The complex physical and chemical interactions create a robust zinc-iron alloy layer, seamlessly integrating with the pure zinc layer and steel substrate, ensuring impressive corrosion resistance.
Cold galvanized pipes, characterized by electro-galvanization, offer limited protection with a mere 10-50g/m2 of zinc coating. Their corrosion resistance pales in comparison to hot-dip galvanized pipes. Renowned manufacturers prioritize high-quality processes, thus seldom employ electro-galvanizing, which is often relegated to smaller enterprises with outdated technology due to cost constraints. Notably, the Ministry of Construction has mandated the phasing out of cold galvanized pipes for water and gas applications. These pipes feature an electroplating layer where the zinc does not fully integrate with the steel substrate, resulting in a fragile, easily detachable zinc layer and subsequent reduced corrosion resistance.
Techniques for Rust Removal
(1). Start with a solvent-based cleaning to effectively eliminate organic contaminants from the steel surface, ensuring a pristine base.
(2). Utilize wire brushes and other tools to meticulously remove loose rust, scale, and welding slags, preparing the surface for further treatment.
(3). Employ the pickling method to achieve deep, thorough rust removal, setting the stage for the next stages of processing.
Galvanization Techniques: Delve into the world of galvanization by exploring the two primary methods-hot-dip and cold-dip. Hot-dip galvanizing offers superior rust resistance, making it the preferred choice for long-lasting applications. Conversely, cold-dip galvanizing is more susceptible to rust, requiring careful consideration of its usage conditions.
