Duplex Steel UNS S32205 Seamless Tubes Manufacturer in India
What Are Duplex Steel UNS S32205 Seamless Tubes?
Duplex Steel UNS S32205 Seamless Tubes are tubular products manufactured from duplex stainless steel with a balanced austenitic and ferritic microstructure. UNS S32205, commonly known as Duplex 2205, provides a combination of high mechanical strength, good toughness, excellent corrosion resistance and resistance to chloride-induced stress corrosion cracking.
Duplex Steel UNS S32205 Seamless Tubes are valued for their high strength-to-weight ratio, excellent resistance to pitting and crevice corrosion, good chloride resistance and reliable performance in demanding environments. Their seamless construction provides a continuous tubular structure without a longitudinal weld, making them suitable for pressure, process and heat-transfer applications.
These seamless tubes are used in oil and gas equipment, petrochemical plants, chemical processing systems, marine applications, heat exchangers, desalination plants, power generation and wastewater treatment equipment. The tube grade, outside diameter, wall thickness, schedule, length and finish are selected according to operating conditions and applicable material specifications.
Kamal Steels is a reliable Duplex Steel UNS S32205 Seamless Tubes Manufacturer and Stockist in India, supplying seamless tubes in different sizes, wall thicknesses, schedules, lengths and finishes according to customer and project requirements.
