Abstract: Fracturing pump valve box (2300, 2500 and 2800) for unconventional oil and gas fields is widely used in fracturing service for shale gas field development in Sichuan-Chongqing region. This series of new-type fracturing pump valve boxes is based on innovation of materials, structure and manufacturing process. The inner structure is suitable for double guide rod valve and the overall structure replaces dividing structure. With application of static pressure self-enhanced treatment technology, rolling treatment technology and shot blasting strengthening technology, the product is characterized for high pressure resistance, stabilization, high safety and long service life. It has a good ability against corrosion, alternating stress and fatigue stress in the harsh service environment of high pressure, large displacement and long time. The service life is raised by more than 200 hours under the work pressure of 70-105MPa. The work time surpasses the domestic product of the same kind by more than 30 percent, effectively lowering the service cost.
