Frequently Asked Questions (FAQ)
-
Q: Is this pipe seamless or welded?
A: DIN 2440 standard typically applies to welded steel pipes. However, we can also supply seamless pipes that meet the same dimensional requirements if needed. Please confirm with our sales team. -
Q: Can you provide threaded ends? What thread standard is used?
A: Yes, we can thread the pipe ends. The standard thread for DIN 2440 is BSPT (British Standard Pipe Taper). NPT threading is also available upon request. -
Q: What is the maximum working pressure for this pipe?
A: The allowable working pressure depends on the application and safety factors. For reference, with 2.65mm wall thickness and 21.3mm OD, the theoretical burst pressure is approximately 40 MPa. We recommend consulting a professional engineer for your specific system. -
Q: Do you offer shorter or custom lengths?
A: Yes, we can cut pipes to custom lengths (e.g., 4m, 5m, or 5.8m) with an additional charge. Standard 6m length is the most economical for bulk orders. -
Q: What surface treatment options are available?
A: Standard product is black annealed. For better corrosion resistance, we offer hot-dip galvanized (HDG) or pre-galvanized finish. Please specify your requirement. -
Q: How is the pipe packaged for export?
A: Pipes are bundled with steel straps, wrapped in waterproof plastic, or packed in wooden crates as per your request. We ensure safe handling during sea freight. -
Q: What is the typical lead time for a 20-foot container order?
A: For standard stock sizes, lead time is 7–15 days after payment. For special sizes or surface treatments, it may take 20–30 days.
