RENEWABLE ENERGY
Wind energy is a clean and pollution-free renewable energy source. Wind power refers to the conversion of wind kinetic energy into electrical energy. DHDZ offers a variety of large diameter wind power flanges. It is a structural member that connects each section of the wind tower or between the tower and the hub. The material used for wind power flange is low-alloy high-strength steel Q345E/S355NL. The working environment has a minimum temperature of -40 °C and can withstand up to 12 winds. The heat treatment requires normalizing. The normalizing process improves the comprehensive mechanical properties of the wind power flange by refining the grains, uniformizing the structure, improving the structure defects.
-
OIL & GAS INDUSTRIES
The oil and gas industies demand reliable flanges for Upstream, Midstream and Downstream processes. In the construction of these large-scale projects, the working conditions are diverse and complex, involving a large number of media and materials. There are many special requirements for the quality of the flanges and other fittings. DHDZ offers flanges meeting the requirements for resistance to sulfide stress cracking (SSC) in sour refinery process enviroments, i.e., enviroments that contain wet hydrogen sulfide (H₂S).
