The main work of developing a steel pipe hydrostatic testing machine

1. Research on sealing performance: sealing parts with steel pipe end face, outer diameter end face or radial sealing, as well as sealing performance of various hydraulic cylinders and valve bodies; 2. Research on oil-water balance system: Research on the coordination and control of hydraulic system, low-pressure water system, and high-pressure water system in hydraulic testing units; 3. Research on mechanical structures.
