During shutdown for maintenance, are the on-site pressure gauges and pressure transmitters both calibrated? Recording this in the calibration sheet requires a lot of work
Thread Content
I’d like to hear how various companies handle this situation
Generally, it is necessary to calibrate the pressure gauges and pressure transmitters at the parking and maintenance site, and the calibration results must be recorded in a calibration sheet. This ensures the safe and reliable operation of the equipment. For situations with a large workload, some companies may take the following measures: 1. Allocate tasks reasonably. Based on the availability of personnel and time resources, tasks are allocated appropriately to each responsible person, ensuring that everyone can complete their work successfully. 2. Use automated inspection equipment. Some modern pressure gauge and pressure transmitter calibration devices can perform calibration automatically, reducing the amount of manual work required. 3. Strengthen training and management. By strengthening employee training, improve employees’ skill levels and work efficiency ； At the same time, strengthen management by ensuring standardized work processes and establishing work standards in order to improve work efficiency and quality. In short, the calibration of pressure gauges and pressure transmitters at parking and maintenance sites must be taken seriously to ensure the safe and reliable operation of the equipment. .
The company has established a dedicated metrology department with staff assigned to carry out inspections and keep records.
The main issue is that there’s no dedicated person in charge; there’s too much to do, including inspection lists for valves and so on. With hundreds of circuits, it’s extremely complicated… If everything has to be checked individually, it will take a lot of time
At a petrochemical plant in Northeast China owned by CNPC, a major shutdown for maintenance is underway, during which pressure transmitters on site are all calibrated.
Everything needs to be verified; we have a dedicated metrology department
Major overhaul inspection, mainly involving interlocks and automatic control
Haha, right. I’m going to create an electronic version – adding a little bit each day
