Hindustan Steel and Engineering Company is one of the known stockists and manufacturers of Duplex Steel Pipes and Tubes , where we also offer the same in different grades such as Duplex S32205 Pipes & Tubes, and Duplex S31803 Pipes & Tubes.
These Duplex Steel Seamless Pipes is hot worked in the temperature range of 954 Degree C – 1149 Degree C (1750 Degree F – 2100 Degree F). The best suited heat treatment for this grade is solution treatment (annealing), between the ranges of 1020 Degree C – 1100 Degree C, followed by rapid cooling. Use of welding electrodes for Duplex Steel Welded Pipes from Hindustan Steel and Engineering Company is recommended, where pre heating and post heating are not necessary.
The advantage of a duplex structure is that it combines the favorable qualities of a ferritic alloy (stress corrosion cracking resistance and high strength) with those of an austenitic alloy (ease of fabrication and corrosion resistance). In fact Duplex Steel Seamless Tubes offered by Hindustan Steel and Engineering Company can be used successfully as an alternative to 300 series austenitic stainless steels in almost all applications where higher mechanical strength / lower weight is required.
Duplex Steel Welded Tubes is often used in chemical processing, transport and storage – pressure vessels, tanks, piping, and heat exchangers. Hindustan Steel and Engineering Company also offer these Duplex Steel Tubes in different sizes, shapes and designs as per clients’ specifications at reasonable price.
