FAQ
Q: Why choose LSAW over SSAW for high-pressure gas lines?
A: LSAW has a single straight seam and undergoes cold expansion, which improves dimensional accuracy and reduces residual stress, making it safer for high-pressure combustible gas applications.
Q: What's the difference between seamless and welded pipes?
A: Seamless pipes offer superior strength and pressure rating but cost more. Welded pipes provide excellent value for lower-pressure applications with good dimensional control.
Q: Do you provide material certificates?
A: Yes, we provide mill test certificates, material certificates, and third-party inspection reports upon request.
