During the cold winter, the primary method for preventing freezing in instrumentation is still relying on technicians to inspect and maintain the equipment. When encountering frozen or condensation in circuits, the solution involves blowing with external steam and knocking on the pipeline, a rather primitive and inefficient approach, which also requires significant effort from maintenance personnel. To reduce the workload on pressure gauge maintenance and ensure stable production, as well as to keep the instrumentation equipment safe throughout the winter, the following five measures can be taken to prevent "freezing" damage to the instruments.

Pressure Gauge Installation Procedures

Select a reasonable installation location, instruments and meters should be installed in a dry area without rain or snow leakage.

Insulation Measures

Insulate with thermal insulation materials, i.e., wrap the parts of instruments and equipment that are prone to freezing or sensitive to cold with such materials. As winter approaches, inspect and regularly drain to prevent damage to the insulated packaging materials.

3. Inspection Measures

When conditions permit, a designated professional conducts daily technical confirmation and treatment for the integrity of insulation materials and the unblocking of steam pipelines.

4. Alarm Measures

Optional sound and light alarm devices for steam leakage or power outage can be installed to facilitate the detection and timely rectification of potential hazards in thermal insulation and frost prevention measures.

5. Inspection Measures

The responsible person for regional pressure gauge maintenance conducts scheduled inspections along predetermined routes. During inspections, they check if the insulation pipeline valves, insulation boxes, drainage devices, insulation material packaging, and electric tracing power components are functioning properly. Key inspections are performed on instruments of devices prone to freezing, and inspection records are kept. Maintenance and care for instruments and insulation anti-freezing measures are conducted to ensure they are dry, complete, and clean, and any on-site insulation and heating issues are addressed promptly.
