Frequently Asked Questions (FAQ)
- What is the difference between spiral welded pipe and seamless pipe? Spiral welded pipes are manufactured by welding a spiral seam, making them more cost-effective for large diameters and thinner walls. Seamless pipes have no weld seam, offering higher pressure resistance but at a higher cost. Our spiral welded pipe is ideal for low to medium pressure applications and structural use.
- Can you provide pipes with special coatings? Yes, we offer various coatings such as 3PE, FBE, galvanized, and black painting. Please specify your requirements when ordering, and we will customize accordingly.
- What is the typical lead time for an order? Lead time depends on quantity and specifications. For standard sizes, it is usually 15-30 days after deposit. For custom orders, it may be 30-45 days. We will confirm upon order placement.
- Do you have test certificates for the pipes? Yes, we provide mill test certificates (MTC) for each batch, including chemical composition, mechanical properties, hydrostatic test results, and NDT reports. Additional third-party inspection is available upon request.
- What is the minimum order quantity (MOQ)? Our MOQ is typically 10 tons for standard sizes. For small quantity samples, please contact our sales team.
- Can you ship to my country? We ship to ports worldwide, including Tianjin, Qingdao, Shanghai, and Foshan. Our main markets cover North America, South America, Europe, Asia, Africa, and Oceania. We can handle FOB, CIF, and other trade terms.
- How do you ensure the quality of the welded seam? Our production process includes automatic submerged arc welding with real-time monitoring. Each pipe undergoes hydrostatic testing, ultrasonic inspection, and visual checks. We follow strict quality control standards.
