Sandco Metal Industries specialize in manufacturing of Duplex Steel UNS S31803 tubes available in various grades and dimensions at affordable cost with no quality compromise. We are manufacturing Duplex Steel UNS S31803 tubes (seamless, welded, ERW) from past 25 years under supervision of technical experts with their expert guidance and support. Our Organization is ISO-9001:2008 certified with added advantage of products electro polishing, cutting as per customer requirements.
Duplex tubes are used in regions where austenitic stainless steel is not suitable as it is a cheaper alternative for corrosion resistance to various nickel-based alloys. We have a wide range of Duplex Steel UNS S31803 Pipes & Tubes from ½” to 16” for immediate dispatch. The high mechanical strength of duplex grades is a result of the duplex microstructure and the alloying with nitrogen which gives opportunities for reducing both weight and cost. Duplex products have high thermal conductivity, Low coefficient of thermal expansion. Our Duplex Pipes & Tubes are available as seamless , welded and ERW (ERW stands for Electric Resistance Welded) pipes & tubes .
UNS S31803 Duplex Steel Tubes are available at random lengths of upto 6 meter long or 20 feet long in Seamless / Welded / ERW. UNS S31803 Tubes can be offer at random short length or cut length to specific length as per order. We offer complete range in this grade Buttweld fittings- ellbow,tee,bends,reducer,stubend, UNS SAF S31803 Duplex Forged Fittings & UNS S31803 Duplex Flanges
Alloy 2205 (UNS S31803) is combination of chromium, molybdenum and nitrogen which provides good resistance to chloride pitting and crevice corrosion.UNS S31803 also inhibits high Strength, good weldability and workability . This alloy finds its applications in Food processing equipment, Oil field piping and heat exchangers, Chemical process vessels, piping and heat exchangers. The resistance capability of duplex steel makes it suitable for marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications.
UNS S31803 Duplex Seamless Tubes
Seamless Tubes are manufactured by using an extruded hollow tube or a drilled solid bar which then undergo various tube reduction processes to meet customers specifications.
UNS S31803 Duplex Welded Tubes
Welded Tubesmanufacturing process starts with cold rolled strip of metal, roll formed into tubular shape and seam welded without the use of any filler material which then undergo various cold working techniques like Pilgering, cold drawing etc., until it reaches the exact size, tolerances, and temper in accordance to customer’s specifications.
UNS S31803 Duplex ERW Tubes
ERW Tubesmanufacturing process involves spot and seam welding where the sides are trimmed to control the width and the condition the edges for welding. It is then passed through a number of contoured rollers which cold form the stainless steel into a tube. ERW stands for Electric Resistance Welding.
