Duplex Stainless Steel Pipe Fittings

High-performance duplex stainless steel pipe fittings engineered for demanding industrial environments. Available in elbows, tees, reducers, caps, crosses and flanges, these fittings are manufactured in both welded and seamless forms and offered in commonly specified duplex grades (S31803 / 2205, S32750 / 2507, S32760) for enhanced strength and corrosion resistance.

Key features

• Materials: Duplex stainless steels (S31803 / 2205, S32750 / 2507, S32760) for superior resistance to chloride stress-corrosion cracking and higher yield strength compared with austenitic grades.
• Product range: Elbow, tee, reducer, cap, cross, flange — butt-welding and other connection styles available.
• Size coverage: Outside diameters from 2 mm up to 1600 mm; wall thicknesses from 0.8 mm to 60 mm; also available in square and rectangular profiles.
• Manufacturing: Offered in welded and seamless constructions to match application requirements and design specifications.
• Typical applications: Oil & gas, petrochemical and chemical processing, desalination, marine, pulp & paper, and other corrosive or high-stress service environments.

Supply and specification options

• Custom sizing, connection types and machining available on request to meet project drawings and piping specifications.
• Surface finishes and protective packaging suited for export shipping and on-site handling.
• Inspection and test documentation can be provided on request to support procurement (e.g., material certificates, mechanical test reports and visual/NDT records).

Why choose duplex fittings

Duplex grades combine the toughness of ferritic steels with the corrosion resistance of austenitic stainless steels, delivering higher strength (allowing thinner sections for the same pressure rating) and improved resistance to localized corrosion in chloride-bearing environments. These properties make duplex fittings a cost-effective choice for long-term performance in aggressive service conditions.
