Additional Product Information
Port of machining by cutting and become, within many sharp-angled transition, easy to cause uneven stress at the sharp corners, produce craze. Modular design of welded together at the same time, the forging of the valve seat diameter is relatively fixed, on some valve size, its diameter is small, influence the flow capacity. Causes the valve flow resistance to increase, the entire system efficiency reduction. Due to the limitation of large size valve forging technology and to save cost, many manufacturers usually adopt the structure of the forging parts at both ends and the center part of the valve body. Whether it's casting, forging. It is possible that the product is defective in processing. The main defects of casting are sand holes, air bubbles, etc. The main defects of forgings are large grains, cold and hard phenomena, cracks, cracks and cracks. In order to obtain qualified product quality, the corresponding castings need heat treatment to eliminate the stress in the casting process. Meanwhile, X- ray, magnetic particle inspection, permeability inspection and other detection methods are adopted. For forgings, this requires strict heat treatment of the weld and corresponding testing methods to ensure. Ultrasonic testing is often required for forgings. In addition, it should be mentioned that the welding process is very strict, and the qualification of welding engineers is also the key to ensure the quality of products.
