Inspect the stairs and service areas of the gas separator equipment. Check the serviceability of the lighting, the presence of explosion-proof lampshades on the lamps execution, the integrity of the pipe electrical wiring and switch housings. Check the presence of inscriptions on the inlet and outlet pipelines indicating the nature of the transported medium and arrows indicating the direction of movement of gas and liquid, the tightness of the pipelines. Check the condition of all hatches and flange connections on the device, the absence of gas and liquid leaks , completeness of their fasteners and fastening. Check the serviceability and functionality of the shut-off valves, ease of rotation of the steering wheels, completeness and correct installation of fasteners in the flange connections of the shut-off valves. There should be arrows on the steering wheel indicating the direction of rotation when opening and closing the valve. Check for the presence of signs indicating the valve number according to the technological diagram. Make sure that there are no leaks of gas and liquid through the stuffing box seals. If there are gaps, tighten the stuffing box seal. Check the data on the registration plate, which should indicate: - technological index of the device - serial number - registration number - permitted operating pressure - dates for the next internal inspection and hydraulic test Check the presence, serviceability and suitability of the control measuring instruments. Check the serviceability of the SPVK by forced opening (undermining), the presence of a seal and a plate on it indicating: - Serial number of the valve - Set pressure, Ru - Date of the next inspection and calibration Based on the inspection results, draw a conclusion about the technical condition of the gas separator and the possibility of its further operation. Make an entry in the logbook about the results of the inspection. 21. Report the results of the inspection to the installation manager (shift supervisor) Number of points

Task 1. Select from the proposed technical pressure gauges suitable for measuring working pressure and explain your choice. Installation location of the pressure gauge - gas separator GS with a volume of 8 m3 with a working pressure of 4 kg/cm2. The level of the observation platform is 2 m from the installation site of the pressure gauge.

The duration of the selection of a suitable pressure gauge is 10 minutes. Technical means and equipment pressure gauges of different types, suitable and unsuitable, technological map of the installation, technological diagram of the installation….

Criteria for assessing labor actions Registration of actions Expert comments Complies (2 points) Partially complies (1 point) Does not comply (0 points) Select all pressure gauges with a scale, so that the working readings are 2/3 of the scale. Inspect and reject the selected pressure gauges on the following grounds. : damage to the housing; damage to the threaded connection; glass damage; the arrow reading is not at the zero mark; lack of seal; lack of brand; verification period. Draw a red line or set a red arrow in accordance with the permitted pressure on the selected pressure gauge. Make sure that the arrow of the selected pressure gauge is at the zero mark.
