Duplex Pipe

A Duplex grade is a dual microstructure composed of both austenitic and ferritic grades. A Duplex Pipe is designed with a superior chemical composition of chromium, nickel, and molybdenum with other constituting elements. The outstanding content embedded within this grade gives them enhanced resistance against corrosive and oxidative media across stress-induced environments. The Duplex Stainless Steel Pipe has enhanced strength and load-bearing capacity as compared to normal stainless steel grades. These pipes also have good tolerance against pitting, which is common in marine systems. A Duplex 2205 Pipe works well in elevated temperature setups in temperatures up to 600 degrees F. These pipes are designed with excellent mechanical properties. They have a minimum tensile strength of 116ksi with a minimum yield strength of 80ksi. These pipes can be elongated by 15% in the system. The Duplex 2205 Tube has a hardness of 310 HRB max and is stronger as compared to pipes in this grade. The versatile grade of tubes can be manufactured in a square, circular and rectangular shapes.

A Duplex Tube has excellent fabricability and workability. Designed with a lower thermal expansion, the tube is resistant to intergranular carbide corrosion. These tubes have a density of 7.8 g/cm3 and have enhanced tolerance against crevice corrosion cracking. The 2205 Stainless Steel Tubing can be processed in hot or cold rolling procedures. The versatile grade of tubes can be readily welded in place following the standard welding process. The dual microstructure Uns S31803 Pipe is commonly used in Chemical process plants, pollution control, chemical processing, oil and gas, marine systems, communication networks, pulp and paper, and an array of applications. These pipes are produced by vigorous testing and making use of the best raw material and latest machinery.
