Detailed Product Description
Our 2.5-inch OD hot-dipped galvanized steel pipe is specifically designed for agricultural irrigation systems where reliability and longevity are paramount. The hot-dipping process ensures a uniform, thick zinc coating that adheres tightly to the steel, providing a barrier against moisture, chemicals, and soil corrosion. This makes it an excellent choice for above-ground or buried irrigation lines.
The 2.0mm wall thickness offers a robust balance between weight and strength, allowing the pipe to handle typical irrigation pressures (up to 300 psi, depending on application) without excessive material cost. The pipe is produced in accordance with international standards such as ASTM A53 and BS 1387, ensuring dimensional consistency and mechanical performance. Each pipe undergoes rigorous quality checks, including hydrostatic testing and coating thickness verification, to guarantee defect-free delivery.
For agricultural users, the galvanized coating eliminates the need for additional painting or protective wraps, saving time and labor. The smooth interior surface minimizes friction loss, improving water flow efficiency. Additionally, the pipe is compatible with standard fittings, valves, and sprinkler systems, simplifying installation and maintenance.

Frequently Asked Questions (FAQ)
Q1: What is the difference between hot-dipped and electro-galvanized pipe?
A: Hot-dipped galvanized pipe has a thicker, more durable zinc coating created by immersing the steel in molten zinc. It offers superior corrosion resistance, especially for outdoor agricultural use. Electro-galvanized pipe has a thinner coating applied via electrolysis and is more suitable for indoor applications.
Q2: Can this pipe be used for drinking water?
A: Yes, hot-dipped galvanized steel is commonly used for water supply lines. However, local regulations may vary. Our pipe meets ASTM A53 standards, which allows for potable water applications when properly installed. Please check with your local authority.
Q3: What is the maximum working pressure for this pipe?
A: The working pressure depends on the pipe schedule and application. For a 2.5-inch OD x 2.0mm wall (approx. Schedule 40), the maximum working pressure is typically around 300 psi (20 bar) for water. We recommend consulting a professional engineer for your specific system design.
Q4: Do you offer threaded ends or grooved ends?
A: Yes, we can provide plain ends, threaded ends (NPT or BSP), or grooved ends for mechanical couplings. Please specify your requirements when ordering.
Q5: What lengths are available?
A: Standard length is 6 meters (20 feet). Custom lengths from 1 meter to 12 meters are available upon request. Minimum order quantity may apply for custom lengths.
Q6: How is the pipe packaged for export?
A: Pipes are typically bundled in steel straps with protective end caps, or packed in wooden crates for smaller quantities. We can also arrange custom packaging based on your shipping method (FCL, LCL, or air freight).
Q7: What certifications do you have?
A: Our company is ISO9001 certified. We can also provide test reports and certificates of compliance for each shipment, including mill test certificates (MTC) as per EN 10204 3.1.
Q8: Do you provide samples before bulk order?
A: Yes, we can provide samples of approximately 1 meter length. The buyer is responsible for sample shipping cost, which can be deducted from the first order if placed. Please contact our sales team for details.
