David Pipes and Tubes, located in Canberra, Australia, has built a solid reputation as a leading manufacturer and supplier of stainless steel 316H EFW pipes. These Electric Fusion Welded (EFW) pipes are crafted for top-notch performance in high-temperature and corrosive settings, where strength, durability, and resistance to scaling are absolutely essential. Thanks to the higher carbon content in stainless steel 316H, these pipes boast enhanced tensile and creep strength, making them perfect for elevated temperature applications. David Pipes and Tubes takes pride in their precision fabrication, smooth internal finishes, and strict adherence to international quality standards, ensuring they deliver reliable and long-lasting piping solutions for a variety of industrial needs.
Stainless steel 316H EFW pipes are made up of chromium (16–18%), nickel (10–14%), and molybdenum (2–3%), with that extra carbon content boosting their mechanical strength and stability at high temperatures. These pipes showcase impressive tensile strength ranging from 515 to 700 MPa, yield strength between 205 and 275 MPa, an elongation of 40%, and a hardness of about 90 HRB. This composition grants them remarkable resistance to oxidation, pitting, and crevice corrosion, even in harsh chloride and acidic environments, all while maintaining excellent formability and weldability.
