David Pipes and Tubes, located in Canberra, Australia, has earned a solid reputation as a reliable manufacturer and supplier of Hastelloy ERW Pipes. These pipes are crafted from a high-performance nickel-molybdenum-chromium alloy, specifically designed to thrive in corrosive and high-temperature settings. Utilizing cutting-edge Electric Resistance Welding (ERW) technology, they guarantee consistent wall thickness, smooth internal surfaces, and impressive dimensional accuracy. Whether it’s for chemical processing, petrochemical, oil and gas, or power generation, Hastelloy ERW Pipes from David Pipes and Tubes are the go-to choice for industries that demand corrosion resistance, durability, and a long service life.
The composition of Hastelloy ERW Pipes includes nickel (57–72%), molybdenum (16–22%), and chromium (6–10%), along with trace amounts of iron, cobalt, and tungsten, depending on the specific grade. This unique blend offers outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking, even in harsh chemical and high-temperature conditions. With a tensile strength ranging from 550 to 900 MPa, these pipes also boast excellent ductility and remarkable thermal stability. The ERW process not only ensures robust, leak-proof welds but also maintains consistent mechanical properties along the entire length of the pipe.
