Super Duplex Steel EFW Pipes Supplier

Super Duplex Steel is a material that has the features of ferritic steel and austenitic steel. Super Duplex Steel EFW Pipes possess high strength from the ferritic structure and high corrosion resistance from the austenitic structure. The Super Duplex Steel EFW Pipes built with chromium, molybdenum, nickel and nitrogen in its composition. Additionally, there is high corrosion resistance and strength. These Super Duplex Steel EFW Pipes are easy to install and handle, and they are very much accurate in their dimensions. These Super Duplex Steel EFW Pipes are therefore used in high pitting corrosion prone environments such as the deep-water offshore oil drilling. The Super Duplex Steel EFW Pipes are electric resistance welded and retains the strength after welding and does not compromise the corrosion resistance properties. These pipes are extremely usable in the areas of marine, chemical processing, petrochemicals, power generation, food processing
The EFW process involves rolling a plate into a pipe and joining it together with a weld. This process removes weld flash and enables the weld zone to be heat-treated. Once the pipe is welded, it undergoes mechanical tests. These tests include a hydrostatic test and a transverse tension test.
Super Duplex Steel EFW Pipes are suitable for applications where temperatures can be below 600 degrees Fahrenheit. Moreover, they are highly resistant to organic Plateids, acetic acid, and formic acid. As a result, these pipes are an excellent choice for oil and gas equipment.
They can also be used for welding. As they have low thermal expansion, they can be easily welded. A super duplex pipe can withstand welding and cutting processes. There is no need to apply specialized welding techniques.
As per ASTM A928 specification, Super Duplex Steel EFW Pipes are manufactured in different forms. They come in SAF 2507 Hollow Pipes and ASTM A928 Welded Pipes. ASTM A928 Pipes is a special category of ERW pipes made from Super Duplex Steel.
