What is electric heat tracing technology for pipelines?
Electric heat tracing technology of pipeline is a technology to keep the surface of pipeline at a certain temperature by electric heating. It can help the pipeline to maintain normal operation in low temperature environment and avoid freezing or solidification of the medium in the pipeline.
Operation steps of pipeline electric heat tracing technology
Step 1: Determine the insulation requirements of the pipeline.
Before the pipeline is insulated, the insulation requirements of the pipeline must be determined. This includes the temperature range of the pipeline, the flow rate and properties of the medium, etc. Only by knowing this information can we choose suitable insulation materials and pipeline electric heat tracing equipment.
Step 2: Select the pipe insulation material.
According to the thermal insulation requirements of the pipeline, select the appropriate thermal insulation materials. Common thermal insulation materials include glass wool, polyurethane foam, aluminum silicate, etc. At the same time, the appropriate insulation thickness should be selected to achieve the insulation effect.
Step 3: Install the pipeline insulation material.
Install thermal insulation materials as required. Note that the joints of thermal insulation materials need to be sealed to prevent heat loss.
Step 4: Install pipeline electric heat tracing equipment.
According to the insulation requirements of the pipeline, choose the appropriate electric heat tracing equipment for the pipeline. Common electric heat tracing equipment for pipelines includes electric heat tracing belt, electric heat tracing felt and so on. Install electric heat tracing equipment on the surface of pipeline, and pay attention to waterproof treatment of equipment wiring.
Step 5: Connect the power supply.
Connect the pipeline electric heat tracing equipment to the power supply, and pay attention to the voltage and current of the power supply to match the equipment. Before connecting the power supply, it is necessary to test the leakage of the equipment to ensure that the equipment does not leak electricity.
Matters needing attention in electric heat tracing technology of pipeline
warn
Safety should be paid attention to in pipeline electric heat tracing technology. Operators need to wear insulating gloves, insulating shoes and other personal protective equipment to prevent electric shock accidents.
Pay attention to waterproofing
When installing pipeline electric heat tracing equipment, attention should be paid to waterproofing. The wiring of the equipment needs to be waterproof to prevent moisture from entering the equipment and causing equipment failure.
Pay attention to maintenance
Pipeline electric heat tracing equipment needs regular maintenance to ensure the normal operation of the equipment. Maintenance includes cleaning the surface of the equipment and checking whether the wiring is loose.
