Virgin Engineers are leading enterprises that are globally dealing as a producer, supplier and stockiest of Duplex Steel S31803 / S32205 Pipes and Tubes. These pipes and tubes are made available at various grades, sizes, wall thickness, types, standards, length, dimensions, schedules, outer diameter, etc. These pipes are tubes are globally appreciated among the large numbers of industrialists for durability, smooth finishing, corrosion resistance, dimensional accuracy, etc. It is also provided to the buyers at custom-built specifications.
Grade 2205 today has become one of the widely used duplex stainless steel (austenitic/ferritic) grades. It has today found in many applications because of being corrosion resistant and has high tensile strength. By many steel suppliers, the standard duplex S31803 composition has been greatly refined and it thus results in restricting the composition ranges that were authorized as UNS S32205. Grade S32205 is providing well-assured corrosion resistance. For duplex S31803 recently produced is complying with S32205. But grade 2205 is not suitable for the usage of the temperature ranging more than 300 Deg C. The reason is that it suffers from the precipitation of the brittle micro constituents.
Properties of the Duplex Steel S31803 / S32205 Pipes and Tubes-
There are few good properties found in the product because of which it has become the right choice for tough applications in many big industries. The pipes and tubes are having the ability to resist high corrosion. It has greater tensile strength, comprising very good toughness and durability, long-term working services and stress corrosion cracking resistance. This grade of pipes and tubes can oppose grain boundary precipitation.
Manufacturing of the pipes and tubes-
The manufacturing of Duplex Steel S31803 / S32205 Pipes and Tubes is done with the clear aim of bringing out the best possible quality of the product. We are making use of tested and high quality of alloy with most modern technology and contemporary tools for fabricating very good quality of pipes and tubes.
