DEVICE FOR AIR BLEED FROM OIL PIPELINE

摘要

FIELD: oil and gas industry.SUBSTANCE: device includes an equipment for air bleed and return to a pipeline of oil removed with air, which includes a valve that is tightly connected to the oil pipeline by means of a branch pipe; the above equipment is made in the form of a combination of a vertical pipe connected to the valve, which is connected to an inclined pipe oriented towards oil movement and connected to the oil pipeline by means of a gate valve arranged on a vertical branch pipe connected to the lower end of the inclined pipe; a vertical edge of the vertical pipe is arranged with exceedance of h above upper part of the inclined pipe and is equipped with a gate valve.EFFECT: improving operating reliability of the device at compressed air bleed from the oil pipeline owing to simplifying the device design; simplifying the return scheme of oil leaving the oil pipeline at compressed air bleeding-off, and possibility of automatic activation and deactivation of the device at compressed air bleed from the oil pipeline.1 dwg
