Unmatched Characteristics & Core Advantages

Superior Performance & Durability: The inherent corrosion resistance of stainless steel, enhanced in grades like 316L or duplex, ensures these Large Diameter Pipes excel in harsh environments—resisting pitting, crevice corrosion, and stress corrosion cracking. This translates to drastically reduced maintenance costs and extended system longevity.

Advanced Manufacturing & Technology: Our pipes are produced using state-of-the-art automated welding (SAW) and forming technologies, guaranteeing consistent weld penetration, excellent bead profile, and uniform mechanical properties. Strict process control and comprehensive non-destructive testing (NDT), including ultrasonic and radiographic testing, ensure flawless integrity.

Key Application Areas:

•
Oil, Gas & Petrochemical: Process piping, feedwater lines, offshore platforms, refinery pipelines.
•
Power Generation: Main steam and feed lines, flue gas desulfurization (FGD) systems, condenser tubes.
•
Pulp & Paper: Digester lines, bleach plant piping, chemical recovery systems.
•
Water & Waste Treatment: Saltwater conveyance, effluent lines, municipal water distribution.
•
Mining & Desalination: Slurry transport, high-chloride feedwater in desalination plants.

FAQ

•
Q: What is the difference between welded and seamless for Large Diameter Pipes?

A: Seamless pipes are standard for smaller diameters under high pressure. For large diameters, welded pipes (especially SAW) are the industry standard, offering excellent strength, more cost-effectiveness, and availability in larger sizes. Our welded pipes undergo rigorous testing to match performance needs.
•
Q: How do I choose between Grade 304/L and 316/L?

A: 304/L offers excellent general corrosion resistance. Choose 316/L for environments with high chlorides (e.g., coastal, chemical processing) due to its molybdenum content, which provides superior resistance to pitting and crevice corrosion.
•
Q: Can you provide custom sizes and special surface finishes?

A: Yes. We specialize in manufacturing Large Diameter Stainless Steel Pipes to custom OD, wall thickness, and length specifications. Various surface finishes, including pickling/passivation for optimal corrosion resistance, are available.
