Chemical Injection Skid with Variable Output Pressure and Flow

  • Chemical Injection Skid, is a piece of equipment designed to inject chemicals into a system at the required pressure of the system.
  • WINGOIL chemical injection skid provides low-pressure compressed air as a booster power source a pressure to keep convenience and safety. This equipment is applicated in surface low pressure, and downhole high pressure.

  • > Low-pressure compressed air as booster power source to keep convenience and safety.
  • > Adopted pressure to be self-locked to adjust output pressure keeps constant in case of overshoot under air-driven pressure setting constant.
  • > With shockproof and dual scale display pressure gauge.
  • > Equipped with a glass column and high-precision flow control valve to meet the requirements of high flow rate chemical injection.The main -material are glass and 316s to meet the corrosion-proof requirements;
  • > All components, piping and valves are made of 316s or 316L, which can prevent from corrosion effectively ;
  • > Has operation schematic on the control panel, which is easy to observe and operate.
