Exceptional Corrosion Resistance

Engineered from Duplex Stainless Steel with surface pickling and annealing treatment, our Duplex Pipe Bends exhibit outstanding resistance to pitting, cracking, and general corrosion, making them highly suitable for usage in aggressive chemical and high-salinity conditions where durability is paramount.

Precision Manufacturing and Customization

Available in seamless and welded forms, these pipe bends adhere to ASTM A815 specifications and support strict 0.5 mm tolerance. Our advanced forming and solution annealing process ensures mechanical reliability, and custom sizes or bends (1D, 1.5D, 2D) cater to diverse project requirements across India and global markets.

FAQ's of Duplex Pipes Bend:

Q: How are Duplex Pipes Bends manufactured and tested for quality?

A: These bends are produced using seamless and welded techniques, followed by solution annealing for enhanced strength. Each product undergoes hydrostatic and dye penetrant inspection (DPI) to guarantee pressure integrity and weld quality before packaging in wooden cases or bubble wrap.

Q: What are the benefits of using Duplex Stainless Steel for pipe bends?

A: Duplex Stainless Steel offers a combination of high tensile (minimum 620 MPa) and yield strength (minimum 450 MPa), exceptional corrosion resistance, and a 25% minimum elongation at break. This ensures longevity and reliable performance in demanding industrial settings.

Q: Where can Duplex Pipes Bends be used effectively?

A: They are designed for use in process piping, high-corrosive environments, and industries such as chemicals, petrochemicals, and oil & gas, thanks to their resilience against aggressive fluids and wide temperature range (-40C to 300C).

Q: When should you opt for seamless versus welded Duplex Pipe Bends?

A: Seamless pipe bends are preferable for critical operations needing superior integrity and pressure resistance, while welded options suit general applications where flexibility in diameter and length is prioritized.

Q: What customization options are available for these pipe bends?

A: Clients can specify diameter (12mm to 600mm), length (up to 6 meters), bend radii (1D, 1.5D, 2D), thickness (4mm to 20mm), and connection type (welded or flanged) to match unique pipeline configurations and requirements.

Q: How does the product ensure reliable sealing and mechanical fit?

A: With a metal-to-metal sealing type, plain or beveled ends, and strict dimensional tolerances, these bends achieve robust joining with pipes, minimizing leakage risks during high-pressure operations.
