FAQ of ASTM B165 UNS N04400 Seamless Pipe
Q: What is your Minimum Order Quantity (MOQ)?
A: We offer highly flexible MOQs to cater to both large projects and pilot or R&D needs. Please contact us with your requirements.
Q: Can you provide custom sizes and specifications?
A: Absolutely. We specialize in customization. We can supply pipes to exact Outside Diameters (OD), Wall Thicknesses (WT), lengths, and end finishes as per your technical drawings.
Q: What documentation do you provide?
A: We provide full material traceability with complete Mill Test Certificates, which include chemical composition and mechanical property reports, ensuring full compliance with ASTM B165.
Q: Why is seamless pipe better than welded (ERW) for my application?
A: Seamless pipe has no weld seam, which is a potential point of failure under high pressure, corrosion, or cyclic loading. It offers more uniform strength around its entire circumference, making it mandatory for critical and high-pressure services.
