Duplex Steel Pipes

Product Details:

Duplex 2205 Pipe in 50NB × Schedule 80S specification is a high-strength, corrosion-resistant pipe manufactured for demanding industrial applications where both mechanical strength and corrosion protection are critical. Duplex 2205, a nitrogen-enhanced duplex stainless steel, consists of a balanced microstructure of austenite and ferrite, giving it nearly double the strength of standard austenitic stainless steels like SS 304/316 while offering outstanding resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking. This makes it highly suitable for aggressive chloride environments, seawater exposure, and high-pressure systems.

In this size, 50NB (2" NB) Schedule 80S Duplex 2205 Pipe ensures thick-wall strength suitable for high-pressure fluid handling, chemical lines, heat-exchanger piping, offshore structural systems, pulp & paper processing, and petrochemical applications. The pipe maintains excellent dimensional stability, weldability, and toughness across a wide temperature range. Its superior PREN value (typically >34) ensures long-term reliability against localized corrosion in chloride and acidic media.

Duplex 2205 pipes are commonly supplied in solution-annealed and pickled condition as per ASTM A790 / ASTM A928 standards, ensuring consistent mechanical properties, smooth internal finish, and enhanced corrosion resistance. The robust mechanical performance—yield strength around 450 MPa and tensile strength exceeding 620 MPa—makes Schedule 80S ideal for high-pressure and critical service where both safety and longevity are essential.

For genuine supply and technical support, Duplex 2205 Pipes in 50NB × Schedule 80S rating are available with Raj Metals located in Mumbai.

Super Duplex Stainless Steel 32750 pipes are high-performance tubular products designed for use in extremely corrosive and high-pressure environments. This grade corresponds to UNS S32750 and is classified as a super duplex stainless steel, featuring a balanced austenitic–ferritic microstructure. This dual-phase structure provides an excellent combination of very high mechanical strength and outstanding resistance to corrosion, particularly in chloride-rich and seawater applications.

In various international standards, Super Duplex 32750 pipes are known by equivalent designations such as UNS S32750 in ASTM/ASME standards, EN 1.4410 in European specifications, DIN X2CrNiMoN25-7-4, and ISO 17781 – X2CrNiMoN25-7-4. The grade is also widely recognized in industry under the trade name Super Duplex 2507.

Super Duplex 32750 pipes are available in seamless and welded forms and can be supplied in different nominal bores, outside diameters, wall thicknesses, and schedules as per project requirements. These pipes exhibit excellent resistance to pitting, crevice corrosion, and chloride stress corrosion cracking, along with good weldability when appropriate welding procedures and consumables are used.

Due to their superior strength and corrosion resistance, Super Duplex 32750 pipes are extensively used in oil and gas production and processing, offshore platforms, marine and shipbuilding applications, chemical and petrochemical plants, desalination and seawater handling systems, heat exchangers, pressure piping, and hydraulic systems.

Super Duplex 32750 pipes are manufactured and supplied by Raj Metals, Mumbai, with full material traceability and test certification available on request. For technical details, sizes, standards, or commercial enquiries, Raj Metals can be contacted at +91 81045 97964.

Product Details:

Super Duplex Stainless Steel 32760 Seamless Pipe in 80 NB × Schedule 80 is a high-performance piping product designed for extremely demanding service conditions requiring very high mechanical strength and superior corrosion resistance. Super Duplex 32760 offers exceptional resistance to pitting, crevice corrosion, erosion corrosion, and stress corrosion cracking, particularly in chloride-rich, marine, and offshore environments, making it one of the most reliable materials for severe service applications.

The 80 NB seamless pipe with Schedule 80 wall thickness provides enhanced pressure-handling capability and structural strength compared to lighter schedules, ensuring safe and long-term performance in high-pressure and high-temperature systems. The seamless construction eliminates weld seams, resulting in uniform metallurgical properties, improved fatigue resistance, and superior reliability for critical process pipelines.

Super Duplex 32760 seamless pipes exhibit good weldability when proper welding procedures are followed and maintain excellent toughness and dimensional stability across a wide temperature range. The balanced ferritic–austenitic microstructure ensures high yield strength—approximately twice that of conventional austenitic stainless steels—while retaining excellent corrosion resistance.

Equivalent and standard designations for Super Duplex 32760 include UNS S32760, EN 1.4501 / X2CrNiMoCuN25-7-4, ASTM A790 / A789, and it is widely known in the industry as Zeron® 100, confirming compliance with major international standards.

These Super Duplex 32760 Seamless Pipes, 80 NB × Schedule 80, are supplied by Raj Metals, Mumbai. For technical specifications, availability, and commercial inquiries, please contact +91 81045 97964.
