The design and installation of electric heat tracing is an important part of its knowledge, and it is also related to the use of electric heat tracing. In the design and installation, there are actually some requirements, which should not be carried out blindly. These requirements should be followed, so that the design can be reasonable and the installation can be correct.
First of all, we use pictures to understand the composition of electric heat tracing, which is conducive to the understanding and mastery of knowledge.
The design requirements for electric heat tracing are:
1. To meet process standards and requirements, the devices in the electric heat tracing system should be able to adapt to the surrounding environment.
2. When the voltage variation range is 15% and the frequency variation range is 2%, the electric heat tracing can work normally and continuously.
3. The heating unit of the electric heat tracing should be made of conductive plastic, the outer sheath should be made of anti-corrosion material, and there should be a shielding layer.
4. The identification of the electric heat tracing system should be standardized, the explosion-proof level should meet the corresponding requirements, and the maximum exposure temperature should meet the design requirements.
5. The materials used in electric heat tracing and power junction boxes must meet the standards and pass the corresponding certification, so that the quality can be guaranteed.
The installation requirements for electric heat tracing are:
1. Electric heat tracing must be covered with aluminum foil, and the heat tracing wire should be installed diagonally below the pipeline.
2. The same heat tracing circuit should be used for the venting, condensate draining pipeline and electric heat tracing process pipeline, and the same is true for the instrument.
3. The insulation performance of the electric heat tracing should be measured, and the measurement should be carried out again before power transmission; after power transmission, the starting current, running current and real-time power should be measured.
4. If it is a concealed project, the specific location and data of the power box, two-way, three-way, and end sealing box of each circuit should be clearly marked, so that it can be easily inquired during maintenance.
