Frequently Asked Questions
ERW (Electric Resistance Welding) is typically used for smaller diameters and standard wall thicknesses, while SAW (Submerged Arc Welding), including LSAW and Helical, is utilized for larger diameters and heavier walls required in high-pressure transmission.
For high-temperature environments up to 650°C, we recommend Chromium-Molybdenum Alloy Steel, specifically ASTM A335 grades like P6, P11, or P22, which offer enhanced creep and oxidation resistance.
Yes, our Low-Temp Carbon Steel (ASTM A333 Gr.1, Gr.6) is impact-tested for toughness at sub-zero temperatures, making it ideal for cryogenic service and cold climates.
We offer a variety of protective coatings including Galvanizing (ASTM A53), Fusion Bonded Epoxy (FBE), and Three-Layer Polyethylene/Polypropylene (3LPE/3LPP) depending on the service environment.
Absolutely. Our pipes are manufactured to API 5L Grade B and X-series (X42 to X70) specifications, meeting the strict pressure and safety standards required for flow lines and transmission pipelines.
We provide Plain ends for standard fit, Beveled ends for professional welding, and Threaded & Coupled (T&C) ends for specific installation requirements.
