They specialize in high-performance stainless steel tubes that are expertly designed to offer exceptional corrosion resistance, mechanical strength, and stability at high temperatures. Crafted with precision, these tubes boast uniform wall thickness, smooth internal surfaces, and impressive dimensional accuracy. The Duplex Steel Boiler Tubing from David Pipes and Tubes is perfect for use in boilers, heat exchangers, and high-pressure steam systems across various industries, including chemical processing, power generation, petrochemical, and marine sectors, where durability, reliability, and a long service life are essential.
This type of tubing is primarily made up of 22% chromium, 5–6% nickel, 3% molybdenum, and 0.14–0.20% nitrogen, which together create a balanced duplex microstructure. This unique composition provides outstanding resistance to pitting, crevice corrosion, and stress-corrosion cracking, especially in high-temperature and chloride-rich environments. The tubing showcases a tensile strength ranging from 620 to 850 MPa, a yield strength between 450 and 550 MPa, and good ductility, ensuring it maintains its mechanical integrity even under extreme pressure and temperature conditions.
