Labdhi Metals is a trusted manufacturer, stockist, and exporter of Duplex 2205 Tubes and Pipes, offering high-performance piping solutions for industries requiring superior strength and corrosion resistance. Duplex 2205, a nitrogen-enhanced duplex stainless steel, contains nearly equal proportions of austenite and ferrite, which provides it with excellent mechanical properties and resistance to stress corrosion cracking, pitting, and crevice corrosion. Labdhi Metals supplies both seamless and welded tubes and pipes in this grade, designed to meet the most demanding applications.
Duplex 2205 is designated under UNS S32205/S31803 and is widely used in industries such as oil and gas, petrochemical, chemical processing, marine, and power generation. These industries benefit from the high yield strength (about twice that of conventional austenitic stainless steels) and excellent corrosion resistance offered by Duplex 2205. Labdhi Metals manufactures and supplies pipes and tubes in various forms such as round, square, rectangular, and custom-shaped as per client requirements.
As a reliable stockist, Labdhi Metals maintains a large inventory of Duplex 2205 tubing and piping in a variety of sizes, wall thicknesses, and finishes. These pipes and tubes are available in schedules from SCH 10 to SCH 160, with outer diameters ranging from 6 mm to 610 mm, and wall thicknesses up to 30 mm. This ready stock enables Labdhi to meet both small and bulk orders with quick turnaround and efficient logistics.
Labdhi Metals is also a reputed exporter, supplying Duplex 2205 tubes and pipes to markets across Europe, the Middle East, North America, Africa, and Asia-Pacific. All products are manufactured under strict quality control and conform to international standards like ASTM A790, ASME SA790, EN 10216-5, and NORSOK M-630. The company conducts various tests including hydrostatic testing, ultrasonic testing, PMI (Positive Material Identification), and dimensional accuracy checks to ensure flawless product delivery.
