Duplex Seamless Tube Manufacturer, Supplier, and Exporter in India
he Mcneil Instrument Duplex Steel Pipe derives its name from the dual nature inherent in the alloy’s microstructure. Mcneil Instrument’s Duplex Stainless Steel Seamless Pipe exhibits excellent mechanical properties and can be utilized in an as-welded state. Regarded as superior compared to austenitic alloys like ASTM A312 TP304 or ASTM A312 TP316, the Seamless Duplex Pipe offers significantly enhanced resistance to corrosion.
Mcneil Instrument offers Duplex Pipe in custom lengths and sizes, a feature particularly beneficial when exposed to corrosive environments containing compounds causing chloride stress corrosion and pitting corrosion. The Duplex Welded Pipe also boasts higher tensile strength properties compared to standard austenitic stainless steel grades. Primarily utilized in the offshore oil and gas industry, the lower nickel content in Duplex Pipe makes it cost-effective. As a leading distributor and manufacturer of A790 Duplex Pipe, Mcneil Instrument ensures the supply of high-quality products to its customers.

Features & Benefits of Duplex Stainless Steel Pipe
Purchase directly from Mcneil Instrument, a leading manufacturer, supplier, and exporter of Duplex pipes, ensuring genuine materials, competitive pricing, and expedited global deliveries. Our products adhere to ASTM A790/ASTM A928 American specifications. Although more challenging to machine and form compared to austenitic materials, our Duplex pipes offer double the design strength of both austenitic and ferritic stainless steels. While weldable, thick materials require extra care during the welding process. With a maximum temperature limit of 300°C, our Duplex pipes exhibit superior toughness down to -80°C, although they are not suitable for cryogenic applications. Mcneil Instrument offers a diverse range of corrosion resistance options to suit various applications, making our Duplex pipes ideal for resisting stress corrosion cracking.
