Presenting our premium Hot Dip Galvanized Round Steel Pipes, also known as GI Pipes. These Pre Galvanized Steel Pipes or Galvanized Tubes are crafted with excellence to meet diverse construction demands.
Our top-tier Galvanized Welded Steel Pipes, featuring a robust hot-dip galvanized coating, are the epitome of reliability and durability. These versatile pipes are integral to a myriad of industries, including construction, machinery, coal mining, chemicals, electric power, railway vehicles, and the automobile sector. They also serve key roles in infrastructure, such as highways, bridges, and containers, as well as in sports facilities, agricultural machinery, petroleum and prospecting machinery, and greenhouse construction, making them an essential choice for manufacturing and industrial applications.
Galvanized steel pipes are expertly engineered welded steel pipes, enveloped in a protective hot-dip or electro-galvanized layer. This advanced galvanizing process significantly enhances the corrosion resistance, thereby extending the lifespan of the pipes. These galvanized pipes are highly versatile, serving as pipeline solutions for various low-pressure fluids like water, gas, and oil. They are also crucial in the petroleum industry as oil well and oil pipes, especially in offshore oil fields. Additionally, they are utilized in oil heaters, condensers within chemical coking equipment, coolers, coal distillation washing oil exchangers, as well as in structural applications like trestle piles and supporting frames for mine tunnels, showcasing their indispensable role in industrial and construction settings.

Hot-dip galvanized pipe undergoes a sophisticated process where molten metal seamlessly bonds with the iron matrix to create a robust alloy layer, ensuring a perfect union between the coating and the base. This involves an initial pickling of the steel to eliminate iron oxide, followed by immersion in an ammonium chloride, zinc chloride, or a combination solution, culminating in the hot dip bath. The numerous benefits of hot-dip galvanization include remarkably uniform coating, exceptional adhesion, and an extended lifespan. Through intricate physical and chemical interactions with the molten plating solution, the substrate transforms into a zinc-iron alloy layer, celebrated for its dense and corrosion-resistant properties. Fully integrated with pure zinc and the steel substrate, this composition offers formidable resistance against corrosion.
Cold galvanized pipe, or electro-galvanized pipe, features a minimal zinc coating of merely 10-50g/m2, resulting in markedly reduced corrosion resistance compared to hot-dip galvanized pipes. Reputable manufacturers avoid this method, leaving it to outdated facilities that offer lower prices due to substandard processes. The construction industry has mandated the phase-out of such pipes, particularly for water and gas applications. The zinc layer, simply electroplated onto the steel, lacks robustness, being thin and prone to detachment, which significantly diminishes its protective capabilities.
Rust Removal Method
(1). Begin by using a solvent to meticulously cleanse the steel surface, ridding it of any organic substances.
(2). Employ tools like a wire brush to effectively eliminate rust, including loose or scaling rust, welding slag, and other residues.
(3). Proceed with the pickling method for thorough rust removal.
Galvanizing is categorized into hot-dip and cold-dip techniques. Hot-dip galvanizing stands out for its superior rust resistance, whereas cold-dip galvanizing is more susceptible to rust.
How to Store Galvanized Pipes:
Galvanized steel pipes should be stored in clean, well-drained locations, distanced from factories or mines emitting harmful gases or dust. The site must be cleared of weeds and debris to maintain cleanliness. In warehouses, galvanizing materials must not be stored alongside corrosive substances like acids, alkalis, salts, or cement. Different types of square tubes should be carefully separated to avert mixing and contact corrosion. Larger sections, rails, steel plates, large-diameter pipes, and forgings can be safely stored outdoors.
Small square pipes, thin steel plates, strips, silicon steel sheets, small-diameter, or thin-walled steel pipes, alongside cold-rolled or galvanized steel pipes and other metal products sensitive to corrosion, are best stored indoors. Warehouses should be chosen based on location, with ordinary closed warehouses being ideal, featuring roofs, walls, secure doors, windows, and proper ventilation.
The Advantages of Galvanized Pipe:
1. Economical Processing: Hot-dip galvanizing offers a cost-effective rust prevention solution compared to other coating methods.
2. Long-lasting Durability: Hot-dip galvanized steel pipes boast a lustrous finish, uniform zinc layer, complete coverage without leaks or drips, strong adhesion, and impressive anti-corrosion properties. The anti-rust layer can persist for over 50 years without maintenance; in urban or coastal areas, it maintains protection for 20 years without repair.
3. Exceptional Reliability: Rejoice in the outstanding reliability of our product! The seamless metallurgical bond between the galvanized layer and the steel surface forms a cohesive part of the Hot Galvanized Steel Pipe. This integration ensures that the coating's durability is not just reliable but exceeds expectations, promising long-lasting performance.
4. Robust Coating Toughness: Experience the unmatched strength of our specialized galvanized layer, designed to form a unique metallurgical structure. This robust construction empowers the coating to resist mechanical damage during both transportation and practical use, safeguarding the quality and integrity of your steel pipe.
5. All-Encompassing Protection: Revel in the comprehensive protection that our galvanization process offers. Every inch of the steel pipe is meticulously galvanized, ensuring complete defense even in the most challenging areas such as depressions, sharp corners, and hidden spots, providing thorough and reliable coverage.
6. Efficient and Labor-Saving: Embrace the efficiency of our galvanizing process, which outpaces other coating methods, saving you precious time and labor. Skip the cumbersome on-site painting requirements post-installation, as our advanced technique ensures a swift and smooth construction experience.
