  • Electro Liquid Plug Valve
  • Brief Introduction:

  • Electro-hydraulic plug valves are mainly used in coaxial catalytic cracking units and catalytic cracking units with the same structure. They can cut off the valve catalyst cycle in case of open, shutdown or device failure.

  • Heat exchanger with convergent-divergent tube supported by Ring-nets
  • Brief Introduction:

  • Consists of converged sections and diverged sections regularly which are made in rolling process. Compared with plain tube, the local velocity and pressure vary in the axial direction periodically to enhance the turbulent in the early stage.
