Sagar Steel Corporation is the leading super duplex seamless pipe manufacturer in India, offering superior-grade piping solutions known for exceptional corrosion resistance, high tensile strength, and long-term durability. These pipes are engineered to perform under high-pressure and chloride-rich conditions, making them ideal for offshore oil drilling, desalination plants, and chemical processing facilities. The high chromium, molybdenum, and nitrogen content ensures strong resistance to pitting, stress corrosion cracking, and crevice corrosion. With outstanding weldability and mechanical strength, these pipes are trusted across marine environments and industrial fluid systems requiring reliability in extreme conditions.
We are the best super duplex seamless pipe suppliers in India, delivering seamless pipes with tight dimensional tolerances and smooth internal surfaces for maximum fluid efficiency. Our products conform to international standards like ASTM A790, ensuring compatibility across high-demand sectors including petrochemicals, heat exchangers, and refineries. These pipes are available in a wide range of diameters, thicknesses, and lengths, tailored to meet specialized application needs.
High-strength pipe with superior corrosion resistance for offshore and subsea operations.
Built for aggressive environments, ensuring stability and durability in chemical and marine applications.
What is the use of SS seamless pipe?
Stainless steel (SS) seamless pipes are widely used in various industries due to their strength, durability, and resistance to corrosion and high temperatures. They are ideal for applications that require a smooth, uninterrupted surface with no welds or seams, ensuring uniform strength and reducing the risk of leaks. Common uses include oil and gas transportation, chemical processing, pharmaceutical manufacturing, power generation, and food and beverage industries. SS seamless pipes are also used in heat exchangers, boilers, and high-pressure systems where reliability and corrosion resistance are critical, as well as in structural applications requiring strength and longevity.
What grade is super duplex pipe?
Super duplex pipes are primarily classified under the grades S32750 and S32760, which are known for their superior strength and exceptional corrosion resistance. Grade S32750, commonly referred to as 2507, contains a balanced composition of chromium, nickel, and molybdenum, providing excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, making it ideal for marine and oil and gas applications. Grade S32760, also known as Zeron 100, offers even greater resistance to aggressive environments and is particularly suited for chemical processing and petrochemical industries. Both grades exhibit high mechanical strength and excellent toughness, even at low temperatures, making them suitable for demanding applications.
Is S32750 a duplex or super duplex?
S32750 is classified as a super duplex stainless steel. This grade contains a higher proportion of chromium (around 25%), nickel (around 7%), and molybdenum (around 4%), which gives it enhanced strength and exceptional corrosion resistance compared to standard duplex stainless steels. The super duplex structure, characterized by a balanced microstructure of austenite and ferrite, provides improved resistance to pitting, stress corrosion cracking, and crevice corrosion, making S32750 suitable for demanding applications in harsh environments such as marine, oil and gas, and chemical processing industries.
