    "The casting method of large-scale thin-walled valve body castings" not only improves the efficiency of model production, but also reduces the cost of model production, and also prevents casting defects such as cracks, under-filling and cold insulation of thin-walled valve body steel castings. The sequential solidification of the casting meets the technical requirements of the valve body casting. The assembly tool for the inner and outer tube with through hole support realizes the assembly welding of the GE (ship hangar position) product similar to the 6F.01 nozzle inner and outer tube with through hole support.
    In the future, the company will vigorously carry out scientific and technological innovation work, strive to form more independent intellectual property rights in various work, and effectively protect the company's independent intellectual property rights through legal means such as patent applications, and provide protection for the company's sustainable development. .
