David Pipes and Tubes, located in Canberra, Australia, is a well-respected manufacturer and supplier of stainless steel 310/310S EFW pipes. These Electric Fusion Welded (EFW) pipes are specifically crafted to withstand high temperatures and corrosive environments, providing outstanding oxidation resistance, strength, and durability. They are perfect for industrial applications where high-temperature performance and structural integrity are essential. David Pipes and Tubes takes pride in their precision fabrication, ensuring smooth internal surfaces and compliance with international standards, which results in reliable and long-lasting piping solutions for industries like heat treatment, chemical processing, and power generation.
The stainless steel 310/310S EFW pipes are made up of chromium (24–26%) and nickel (19–22%), with the 310S variant having a lower carbon content that enhances weldability and minimizes carbide precipitation. These pipes boast impressive mechanical properties, including a tensile strength of 515–700 MPa, yield strength of 205 MPa, elongation of 40%, and a hardness of around 90 HRB. This unique composition grants them excellent resistance to oxidation, scaling, and sulfidation at high temperatures, along with remarkable creep resistance and structural stability during thermal cycling.
