DIN17175 Seamless Boiler Tube description
DIN 17175 is a technical standard for seamless steel tubes at high temperatures, issued by the German Institute for Standardization, specifically designed for high-temperature and high-pressure equipment such as power station boilers and heat exchangers. Our products achieve excellent room-temperature strength, high-temperature creep resistance, and weldability through precise alloy element ratios (C ≤ 0.17%, Cr: 0.7-1.15%, Mo: 0.4-0.6%) and a patented normalizing + tempering heat treatment process. GNEE Group is equipped with a first-class international testing laboratory, featuring advanced equipment such as phased array ultrasonic flaw detectors, creep rupture strength testing machines, and metallographic image analysis systems. Every batch of DIN 17175 steel tubes undergoes comprehensive inspections, from macroscopic defects to microscopic structures, ensuring their safety and reliability under high-temperature and high-pressure operating conditions.
