Manufacturers and suppliers of UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (Super Duplex 2507), engineered for the most demanding and highly corrosive service environments in offshore platforms, oil & gas production facilities, desalination plants, chemical processing units, and marine infrastructure.
Our UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (Super Duplex 2507)
are engineered from a high-performance super duplex stainless steel grade that delivers
exceptional mechanical strength and outstanding resistance to pitting, crevice corrosion,
and stress corrosion cracking. This advanced dual-phase austenitic–ferritic microstructure
makes these tubes ideal for the most aggressive and chloride-rich service environments.
The seamless, precision-engineered construction ensures uniform wall thickness and
smooth internal surfaces, enabling efficient fluid flow and precise control in
critical hydraulic, pneumatic, and sensitive instrumentation systems. These tubes
maintain excellent dimensional stability and structural integrity under continuous
high pressure, elevated temperatures, and cyclic loading conditions.
Widely used in offshore platforms, chemical and petrochemical processing plants,
desalination facilities, marine systems, subsea installations, and heavy industrial
infrastructure, our UNS S32750 stainless steel seamless tubes are manufactured and
tested to international standards to provide a long-lasting, reliable, and
cost-effective solution for the most demanding service applications.
Our UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes are trusted across major industrial cities in India, including Mumbai, Chennai, Pune, Ahmedabad, and Hyderabad. These super duplex tubes support offshore fabrication yards, chemical processing plants, power generation facilities, and heavy engineering projects that demand exceptional strength and superior resistance to aggressive and chloride-rich environments.
Throughout the Middle East, we supply the UAE (Dubai, Abu Dhabi, Sharjah, Ajman, Al Ain, and Ras Al Khaimah), Saudi Arabia, Qatar (Doha), Kuwait, Oman, Bahrain, Iraq, Jordan, and Lebanon. Our UNS S32750 seamless tubes are widely used in offshore oil & gas operations, desalination plants, subsea systems, marine infrastructure, and EPC projects operating under extreme pressure, salinity, and corrosive service conditions.
In Europe, our tubes serve Italy, Germany, Spain, France, the United Kingdom, Turkey, Greece, Austria, and Eastern European markets, where precision engineering and long-term corrosion resistance are critical. Across Africa, the Americas, and the Asia-Pacific region—including the United States, Canada, Brazil, Mexico, Morocco, Algeria, Egypt, Nigeria, South Africa, Singapore, Malaysia, Thailand, Vietnam, and Australia—our UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes support offshore platforms, chemical processing plants, desalination facilities, marine systems, and high-pressure industrial infrastructure.
Wherever you operate—Doha, Dubai, London, Houston, Singapore, Sydney, or New York— Seminox Pipes & Tubes delivers premium-quality UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes, manufactured and certified to international standards to ensure full material traceability, dimensional accuracy, and long-term reliability in critical, pressure-sensitive, and corrosion-intensive hydraulic and instrumentation applications worldwide.
The advanced austenitic–ferritic structure of Super Duplex 2507 provides exceptionally high mechanical strength and superior load-bearing capacity, enabling reduced wall thickness while maintaining excellent pressure ratings in demanding hydraulic and instrumentation systems.
With a high PREN value and enhanced chromium, molybdenum, and nitrogen content, UNS S32750 offers outstanding protection against localized corrosion in chloride-rich, seawater, and highly aggressive chemical environments.
Engineered to perform reliably under high stress and elevated temperatures, these tubes resist stress corrosion cracking in harsh offshore, marine, and chemical processing applications.
Manufactured using advanced cold drawing and seamless forming techniques to achieve tight dimensional tolerances, uniform wall thickness, and smooth internal surfaces for accurate flow control and dependable instrumentation performance.
Designed for controlled welding and forming procedures that preserve the super duplex phase balance, allowing efficient fabrication and installation without compromising corrosion resistance or mechanical integrity.
Delivers extended durability and reduced maintenance in offshore platforms, subsea systems, desalination plants, marine infrastructure, and high-pressure industrial facilities operating in highly corrosive and saline conditions.
UNS S32750 Stainless Steel Seamless Hydraulic & Instrumentation Tubes (Super Duplex 2507) are produced using precision cold drawing and cold rolling processes, followed by controlled solution annealing and pickling or bright annealing to maintain the balanced austenitic–ferritic microstructure. This advanced metallurgy delivers exceptionally high mechanical strength and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, ensuring reliable performance in the most aggressive, chloride-rich, and high-pressure service environments.
Each tube undergoes rigorous quality control, including Eddy Current Testing (ECT), Hydrostatic or Pneumatic Pressure Testing, Positive Material Identification (PMI), chemical composition verification, mechanical property testing, dimensional inspection, and 100% visual examination. Testing is carried out in accordance with ASTM A789, ASTM A790, ASME SA789 / SA790, and relevant EN standards to ensure safe, consistent, and reliable performance in offshore, subsea, oil & gas, chemical processing, desalination, and marine infrastructure applications.
Manufactured and certified in compliance with ASTM A789, ASTM A790, ASME SA789, ASME SA790, EN 10216-5, EN 10297-2, ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, PED 2014/68/EU, and NACE MR0175 / ISO 15156 (for sour service applications, when required). Tubes are supplied with EN 10204 3.1 / 3.2 Mill Test Certificates (MTC), ensuring full traceability, regulatory compliance, and acceptance for EPC, offshore, marine, desalination, petrochemical, and heavy industrial projects worldwide.
