Manufacturers and suppliers of UNS S32750 (Super Duplex 2507) Stainless Steel Seamless High Precision & Heat Exchanger Tubes engineered for extreme service conditions in offshore, oil & gas, chemical processing, and marine applications.
Our UNS S32750 Super Duplex Stainless Steel Seamless High Precision & Heat Exchanger Tubes
are engineered for the most demanding industrial environments where exceptional
mechanical strength, superior corrosion resistance, and long-term operational
reliability are critical. Also known as Super Duplex 2507, this
advanced alloy features high levels of chromium, molybdenum, and nitrogen,
delivering outstanding resistance to pitting, crevice corrosion, and stress
corrosion cracking in aggressive and chloride-rich conditions.
The seamless, high-precision construction ensures uniform wall thickness and smooth
internal surfaces, reducing pressure loss and maximizing thermal efficiency in
heat exchangers, condensers, boilers, and high-pressure piping systems.
These tubes maintain excellent performance across wide temperature and pressure
ranges, making them ideal for offshore platforms, chemical processing plants,
desalination facilities, and marine installations.
Widely used in oil & gas, power generation, chemical, and marine industries,
our UNS S32750 seamless tubes undergo stringent quality control and advanced
testing to meet international standards, delivering a durable, high-performance,
and cost-effective solution for extreme service and critical process applications.
Our UNS S32750 Super Duplex Stainless Steel Seamless High Precision & Heat Exchanger Tubes are trusted across major industrial hubs in India and throughout the Middle East, including the UAE, Saudi Arabia, Qatar, Kuwait, and Oman. These regions rely on our super duplex tube solutions for oil & gas production, offshore platforms, desalination plants, chemical processing facilities, and large-scale infrastructure and energy projects where extreme corrosion resistance and high mechanical strength are essential.
In Europe, we supply Italy, Germany, Spain, the United Kingdom, France, and Turkey, where our UNS S32750 tubes are valued for their superior performance in high-temperature, high-pressure, and chloride-rich environments across chemical, marine, power generation, and thermal processing industries.
Across Africa, the Americas, and the Asia-Pacific region, our super duplex stainless steel tubes support offshore energy, marine engineering, chemical processing, mining, and heavy manufacturing industries, delivering reliable performance in corrosive, high-stress, and extreme operating conditions.
Wherever you operate—Doha, Dubai, London, Houston, or Singapore—Seminox Pipes & Tubes delivers premium-quality UNS S32750 Super Duplex Stainless Steel Seamless High Precision & Heat Exchanger Tubes, manufactured to stringent international standards for durability, traceability, and long-term performance in the world’s most demanding industrial environments.
Manufactured using advanced seamless forming and controlled heat treatment to achieve uniform wall thickness, tight dimensional tolerances, and smooth internal surfaces for optimal fluid flow and heat transfer efficiency.
Super Duplex 2507 stainless steel delivers outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking in highly aggressive, chloride-rich, and seawater environments.
Significantly higher yield and tensile strength than standard duplex and austenitic grades, enabling safe operation in extreme pressure, heavy-load, and structural service conditions.
Maintains mechanical integrity and thermal performance in high-temperature, high-pressure systems such as heat exchangers, condensers, and offshore process piping.
Engineered to withstand chloride-induced and sour-service cracking, ensuring enhanced safety, long-term reliability, and operational stability in harsh industrial and marine environments.
Designed for maximum durability with reduced maintenance requirements, delivering long-term cost efficiency in continuous-duty, corrosive, and high-performance applications.
UNS S32750 Super Duplex Stainless Steel Seamless Tubes are manufactured using advanced hot extrusion and cold drawing processes followed by precision solution annealing and controlled heat treatment. The super duplex microstructure, enriched with chromium, molybdenum, and nitrogen, delivers exceptional mechanical strength and outstanding resistance to pitting, crevice corrosion, and stress corrosion cracking, making these tubes ideal for offshore, marine, oil & gas, chemical processing, and high-pressure heat transfer applications.
Each tube undergoes rigorous inspection and testing including Eddy Current Testing (ECT), Hydrostatic Pressure Testing, Positive Material Identification (PMI), chemical composition analysis, mechanical property verification, dimensional inspection, and detailed visual examination to ensure structural integrity, metallurgical consistency, and reliable performance in extreme service environments.
Manufactured in accordance with ASTM, ASME, EN, and ISO standards, including ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, and PED 2014/68/EU. Tubes are supplied with EN 10204 3.1 / 3.2 certification, ensuring full material traceability, compliance with international regulatory requirements, and adherence to the highest global quality, safety, and environmental management systems.
