Frequently Asked Questions
-
Q: What is the difference between hot-dipped galvanized and pre-galvanized pipe?
A: Hot-dipped galvanized pipe is immersed in molten zinc after fabrication, resulting in a thicker, more durable coating that offers superior corrosion resistance, especially for outdoor and underground use. Pre-galvanized pipe has a thinner coating applied before forming and may not perform as well in harsh environments. -
Q: Can this pipe be used for high-pressure irrigation systems?
A: Yes, depending on the wall thickness selected. Our DN80 pipe with a wall thickness of 3.0 mm or more can withstand working pressures up to 2.0 MPa (290 psi). Please consult our technical team for specific pressure requirements. -
Q: What end connections are available?
A: We offer plain ends for welding, threaded ends for coupling, grooved ends for mechanical couplings, and flanged ends for bolted connections. Custom ends can be arranged upon request. -
Q: What is the typical lead time for an order?
A: For standard sizes and lengths, lead time is usually 15–25 days after deposit. Larger quantities or custom specifications may require 30–45 days. We always keep some stock for urgent orders. -
Q: How is the pipe packaged for export?
A: Pipes are bundled with steel straps, wrapped in waterproof material, and packed in containers. For threaded ends, we protect the threads with plastic caps. Wooden crates are available for extra protection if needed. -
Q: Do you provide samples?
A: Yes, we can provide free samples of short lengths (up to 30 cm) for quality evaluation. The customer only needs to cover the shipping cost. Contact our sales team for sample requests. -
Q: Is the pipe suitable for drinking water systems?
A: While our galvanized pipe is primarily designed for agricultural irrigation, it can be used for non-potable water applications. For potable water, we recommend our internal epoxy-lined or stainless steel pipe options. Please inquire for details. -
Q: What certifications do you have?
A: We are ISO9001 certified. Our products also comply with ASTM A53, BS 1387, and EN 10255 standards. Third-party inspection (e.g., SGS, BV) is welcome and can be arranged at the buyer's cost.
