Core Features

• Superior Corrosion Resistance: Resists pitting, crevice corrosion, and stress corrosion cracking, ideal for marine, chemical, and offshore applications.

• High Strength-to-Weight Ratio: Offers twice the strength of conventional austenitic stainless steel, reducing structural weight and installation costs.

• Temperature Versatility: Performs reliably in extreme temperatures, from low-temperature cryogenic environments to high-temperature industrial processes.

• Precision Manufacturing: Strict dimensional control ensures smooth surface finish, accurate wall thickness (thin wall & thick wall options), and tight tolerance for seamless integration.

• Long Service Life: Excellent fatigue resistance and wear resistance minimize maintenance needs and extend operational lifespan.

Application Fields

Our stainless steel pipes are widely used in key industries:

• Oil & Gas: Downhole tubing, pipelines, and offshore platform components

• Chemical Processing: Reactors, heat exchangers, and fluid transport systems

• Water Treatment: Desalination plants, wastewater treatment, and municipal water supply

• Marine Engineering: Ship hull structures, ballast pipes, and offshore wind energy systems

• Power Generation: Boiler tubes, steam pipelines, and nuclear power plant components

• Food & Pharmaceutical: Sanitary piping for food processing and pharmaceutical manufacturing

Executive Standards

• American Standards: ASTM A790, ASTM A213, ASTM A312, ASTM A480 (for seamless/welded duplex stainless steel pipes)

• International Standards: EN 10216-5, ISO 1127, DIN 17458 (compliant with global quality and safety requirements)

Customization Services

We offer flexible customization to meet specific project needs:

• Custom Length: Cut-to-size options from standard lengths to special requirements

• Wall Thickness: Thin wall (0.5mm–3mm) and thick wall (3mm–50mm+) configurations

• Surface Finish: Annealed, pickled, passivated, or polished surfaces

• End Connections: Plain end, beveled end, threaded end, or flanged end

All products undergo rigorous quality inspections, including non-destructive testing (NDT), chemical composition analysis, and mechanical property testing, to ensure compliance with customer specifications and industry standards.
