Basic Introduction of Valve Left & Right Body Open-Die Forgings (Custom Forgings from Manufacturer)
Founded in 2011, Shandong Qingliang Mould Technology Co., Ltd. has 15 years of experience in forging manufacturing, and is a professional manufacturing enterprise focusing on the R&D, production and customized service of valve left and right body open-die forgings. Focusing on the harsh working conditions of fluid control in industries including petrochemical industry, oil and gas long-distance transmission, power stations, nuclear power and shipbuilding heavy industry, we provide left and right body forgings with stable pressure resistance, reliable dimensional accuracy and good sealing performance for core valves such as ball valves and gate valves. The products comply with national standards, American standards and relevant specifications of JB/T 4728 pressure equipment forgings, and have become long-term supporting suppliers for many backbone valve manufacturing enterprises in China.
Performance Features of Valve Left & Right Body Open-Die Forgings (Custom Forgings from Manufacturer)
Performance Characteristics of Valve Left & Right Body Forgings
Directional Material Gathering + Integral Non-Welded Forging
With a forging ratio ≥4.5, the raw materials are processed by electric furnace smelting + vacuum refining. The cavity, flange and mating surface of the left and right bodies are controlled and formed through special loose tooling, with a metal density ≥99.8%. It helps reduce the strength and sealing risks caused by forged and welded structures, and the metal flow lines are continuous without fracture.
Customized Material Heat Treatment
Customized heat treatment processes are implemented for different materials: normalizing + tempering for carbon steel, quenching and tempering for heat-resistant steel, and solution annealing for stainless steel. Temperature-controlled cooling after forging achieves an internal stress relief rate ≥98%, which helps improve the high-temperature creep resistance and low-temperature impact toughness of the forgings, adapting to mechanical requirements of multiple working conditions.
Precision Pre-Machining of Mating Surfaces
Precision rough machining and surface strengthening treatment are carried out on the mating surfaces of the left and right bodies, with machining allowances reserved and a flatness ≤0.05mm/m. It helps improve the mating accuracy with other valve components, and provides basic guarantee at the forging end for the overall sealing effect of the valve.
