Hot-dip galvanized pipes are truly a testament to the marvels of industrial innovation. This advanced process involves the intricate interaction of molten metal with an iron matrix, crafting an exceptionally resilient alloy layer. The fusion achieved through this method ensures a harmonious bond between the matrix and its protective coating. Initially, the steel pipe undergoes a meticulous pickling process to effectively remove iron oxide residues. Following this, a cleansing dip in a solution of ammonium chloride or zinc chloride, or a combination thereof, prepares the pipe for immersion in the hot-dip bath. Renowned for offering a uniform coating, robust adhesion, and an extended lifespan, this technique facilitates intricate physical and chemical exchanges between the hot-dip galvanized steel pipe and the molten plating solution, producing a corrosion-resistant zinc-iron alloy layer with an impressive, compact structure. This alloy layer seamlessly integrates with both the pure zinc coating and the steel pipe itself, offering formidable corrosion resistance.
Cold galvanized pipes, often referred to as electro-galvanized pipes, are characterized by a minimal zinc coating, typically ranging from 10-50g/m2. This results in significantly inferior corrosion resistance when compared to the more robust hot-dip galvanized pipes. Reputable manufacturers of galvanized pipes predominantly avoid the use of electro-galvanization due to its qualitative shortcomings. Smaller enterprises, equipped with outdated technology, may still resort to this method primarily for its cost-effectiveness. However, current regulations by the Ministry of Construction mandate the phasing out of such antiquated technology, disallowing the use of cold galvanized pipes for crucial applications such as water and gas. The electroplated zinc layer in cold galvanized steel pipes exists independently of the steel substrate, lacking the necessary thickness and adhesion found in hot-dip variants. This deficiency renders them susceptible to peeling and corrosion.
Rust Removal Method
(1). Begin by employing a solvent to meticulously cleanse the steel surface, effectively eradicating any organic contaminants.
(2). Next, utilize mechanical tools, such as wire brushes, to efficiently remove loose or scaling rust, welding slag, and other surface impurities.
(3). Lastly, apply the pickling method for comprehensive rust removal, ensuring a pristine finish.
Galvanizing can be divided into two primary types: hot-dip and cold-dip. Hot-dip galvanizing is your superior choice for rust resistance, while cold-dip is more susceptible to rust.
How to Store Galvanized Pipes:
To ensure optimal storage of galvanized steel pipes, select a site or warehouse that is both impeccably clean and well-drained. Position it away from any factories or mines emitting harmful gases or dust. Remove all vegetation and debris to maintain a pristine environment. Keep corrosive materials such as acid, alkali, salt, and cement separate to prevent detrimental interactions. Different square tube varieties should be stacked distinctly to avoid mix-ups and contact corrosion. Large sections and items like rails, steel plates, and large-diameter pipes may be stored outdoors.
Smaller items, including square pipes, thin steel plates, steel strips, silicon sheets, and various cold-rolled or galvanized steel pipes, particularly those with higher costs and susceptibility to corrosion, should be stored indoors. The warehouse should be carefully chosen to align with geographical factors, preferably featuring an ordinary closed structure with a roof, walls, sealed doors and windows, and proper ventilation for maximum protection.
The Advantages of Galvanized Pipe:
1. Low Processing Cost: Hot-dip galvanizing provides an economical, efficient rust prevention solution compared to alternative paint coatings, making it a cost-effective choice.
2. Durability: With its lustrous surface, uniform zinc layer, and no leakage or dripping, hot-dip galvanized steel pipes showcase remarkable adhesion and corrosion resistance. This robust anti-rust coating can endure for over 50 years without maintenance, and in urban or coastal environments, it remains intact for up to 20 years without requiring repairs.
3. Exceptional Reliability: The galvanized layer seamlessly integrates with the steel surface, forming a robust metallurgical bond that significantly enhances the durability and reliability of our Heavy-Duty Galvanized Steel Pipe. This seamless integration ensures that the coating won't easily wear off, providing a long-lasting protective shield that stands the test of time.
4. Remarkable Coating Toughness: Experience the unparalleled durability of our galvanized layer, meticulously engineered with an exceptional metallurgical structure. This design is crafted to withstand mechanical damage, ensuring enduring strength and integrity of the pipe. Whether under the demands of transportation or the rigor of industrial and commercial usage, this robustness safeguards the pipe, preserving its quality and functionality for years to come.
5. Holistic Protection: Revel in the assurance of our galvanizing process, which promises all-encompassing coverage for every facet of the pipe. Even the most intricate areas-be it depressions, sharp corners, or concealed spots-receive full protection. This comprehensive approach guarantees unwavering performance and reliability, no matter the challenge.
6. Efficient and Cost-Effective: Discover the efficiency and cost savings of our advanced galvanizing process. It not only expedites the procedure but also significantly cuts down labor expenses. Unlike the cumbersome traditional painting methods, our process is completed pre-installation, eliminating cumbersome on-site applications. This results in substantial savings of precious time and resources, streamlining your project execution.
