Atmospheric Gauge Tank

General Introduction

Atmospheric Gauge Tank is the vessel designed for temporal storing of the crude oil after the separation in the separator and surge tanks, used in onshore and offshore well testing operations. Being the part of the well testing system, Atmospheric Gauge Vessel mainly used to measure the flow rate and calibrate liquid metering instruments of the test separator. Atmospheric Gauge Tank has inlet and outlet of the crude oil. Oil enters from the surge tank and emptied by the oil transfer pumps.

Atmospheric gauge tank consists of the enforced vessel to ensure proper storage, sight glasses (level gauges) to control oil level, flame arrestors on each vent of the vessel, a grounding strap, and shearing roof to prevent the vessel from overpressure. Nowadays, gauge tanks rarely used in offshore well test operations and replaced by the surge tank. Also, gauge tank is not used in areas where H2S is presented as this is hazardous to the operation personnel.

Our atmospheric gauge tanks are designed and manufactured for various volumes and pressures.

  • Application:
  • Well Clean-ups
  • Frack Flowback
