High-Quality Hot Dip Galvanized Pipes – Custom Lengths & Thicknesses

        In the fields of modern industry, construction, and energy transportation, steel pipes serve as indispensable foundational materials. Among them, hot-dip galvanized steel pipes, with their excellent anti-corrosion properties and stable mechanical strength, have become the preferred choice for numerous engineering projects.

        Ⅰ.Product Structure and Specification Overview

        Hot-dip galvanized steel pipes are typically manufactured from high-quality carbon steel materials such as Q195 to Q235. They feature a common circular cross-section, with sizes ranging from 1/2" to 8". Wall thickness can be customized (e.g., sch10, sch40, or STD standards), and lengths generally range between 5 to 12 meters. The product complies with international dimensional grade standards such as BS 1387/1985 and EN10219-2:1997, meeting the piping requirements for various industrial systems.

        II. Principle and Advantages of Hot-Dip Galvanizing Process

        Hot-dip galvanizing is a metal surface treatment method that involves fully immersing steel pipes into molten zinc at high temperatures. The specific process includes acid pickling for rust removal, water rinsing, neutralization, drying, zinc immersion, cooling, cleaning, and polishing, ultimately forming a dense galvanized protective layer on the surface of the steel pipe. Additionally, the hot-dip galvanized layer forms a metallurgical bond with the steel, exhibiting strong adhesion and significantly higher resistance to peeling compared to cold-galvanized products.

        III. Wide Range of Applications  

        Thanks to its excellent weather resistance and chemical corrosion resistance, hot-dip galvanized steel pipes are widely used in the following fields:

        • Urban infrastructure construction: such as municipal water supply, drainage systems, and natural gas pipelines;

        • Industrial fluid transportation: including steam, gas, compressed air, and chemical liquids;

        • Agriculture and greenhouse facilities: used for constructing supports, irrigation pipelines, and protective fences;

        • Building and steel structure engineering: serving as scaffolding, safety guardrails, or structural pipes;

        • Marine and port facilities: maintaining long-term stability even in salt spray environments.
