Rajendra Pipe Fittings is a leading manufacturer and supplier of the Duplex & Super Duplex Steel Seamless Pipes. Rajendra Pipe Fittings is recognized as industry-leading expert for Super Duplex Steel Seamless Pipes manufacturing. The Super Duplex Steel Seamless Pipes are produced that meet international and national quality standards. Duplex Steel Seamless Pipes we manufacture are known for their long working life and durable for applications in many industries. Super Duplex Steel Seamless Pipes are considered to provide much greater resistivity to corrosion and to oxidation. We at Rajendra Pipe Fittings are considered to give our clients the highest selection of products. Therefore, we carry out multiple checks on our goods before shipping them to the customers. Some of the tests we perform on our Duplex Steel Seamless Pipes are mechanical Testing Such as Tensile of Area, Chemical Analysis – Spectra Analysis, Positive Material Identification – PMI Testing, Inter-granular Corrosion (IGC) Test, Pitting Resistance Test, Micro, and Macro Test.
The Super Duplex Steel Seamless Pipes are smooth pipes that are highly corrosion resistant and composed of a combination of austenite and ferrite materials. These Seamless Valves are used in high-chloride applications. They show high resistivity to corrosion from pitting and heat. Such Smooth Pipes also show resistivity to crevice corrosion and cracking. The Duplex Steel Seamless Pipes are usually not appropriate for high temperature applications, above 300 ° C temperatures, where micro-components are likely to suffer from embrittlement. Such Seamless Pipes are outstanding for corrosion resistance and oxidation resistance at elevated temperatures. They are resistant to corrosion from corrosion cracking from chloride heat. The Seamless Super Duplex Steel Pipes exhibit high resistivity against seawater. Generally stronger than SS Smooth Pipes number 316. They contain large quantities of chromium, which increases the resistivity to corrosion of these Seamless Pipes. They have a high tensile strength of 620 Min MPa.
The Duplex Steel Seamless Pipes are used in many industries such as the chemical manufacturing, shipping and storage industries for applications. They are also seen in maritime environments, oil and gas mining machinery, and offshore platforms. The Seamless Super Duplex Steel Pipes are also used in the oil and gas refining industries.
