Benefits for Offshore Applications: The cold-rolled surface reduces roughness and improves fluid flow efficiency, while the long seam construction minimizes weld joints and potential leak points. This pipe is specifically designed to withstand high pressure, cyclic loading, and aggressive seawater conditions. It is widely used in seawater intake/discharge lines, firewater systems, chemical injection lines, and instrumentation tubing on offshore platforms. Our factory's strict quality management ensures each pipe meets the highest standards for offshore safety regulations.
The 60x3mm size is optimal for medium-duty offshore piping, offering a good balance between weight, strength, and flow capacity. The cold rolling process enhances the material's grain structure, resulting in improved toughness and resistance to fatigue. Additionally, the precision welding ensures uniform weld bead geometry, making it easier to install and inspect in the field.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between ASTM A928 and other stainless steel pipe standards?
A: ASTM A928 specifically covers longitudinally welded stainless steel pipe made from ferritic/austenitic (duplex) or austenitic stainless steel with filler metal addition. It is designed for high-corrosion environments like offshore, offering better weld integrity and crack resistance compared to standard A312 pipes. -
Q: Can this pipe be used for subsea applications?
A: Yes, the 60x3mm cold rolled welded long seam tube is suitable for subsea systems, provided additional coating or cathodic protection is applied as per your project requirements. The material composition and weld quality meet typical offshore standards. -
Q: What grades of stainless steel are available for this pipe?
A: We offer common grades like 304, 304L, 316, 316L, and also duplex grades (e.g., 2205) upon request. The specific grade affects corrosion resistance and mechanical properties; please consult our team for the best grade for your application. -
Q: How is the long seam weld quality ensured?
A: We use automated TIG or plasma welding with real-time monitoring. Each weld is visually inspected, and non-destructive testing (NDT) such as radiographic or ultrasonic testing can be performed as per your specification. Hydrostatic testing is standard. -
Q: What is the minimum order quantity (MOQ) for this pipe?
A: Our MOQ is typically 500 meters for standard sizes, but we can accommodate smaller quantities for sample orders or urgent projects. Please contact us for details. -
Q: Can you provide custom lengths or end preparations?
A: Yes, we can cut pipes to any length between 1m and 12m, and provide beveled, threaded, or plain ends. Custom packaging (e.g., crating for sea freight) is also available. -
Q: What is the delivery time for this product?
A: For standard sizes and quantities, delivery time is usually 15-25 days after order confirmation. Rush orders may be expedited; please inquire. -
Q: Do you provide third-party inspection?
A: Yes, we can arrange inspection by your nominated third-party agency (e.g., SGS, BV, DNV) at additional cost. We also welcome customer visits to our factory.
