What are the quality requirements for electric heat tracing installation?
Thread Content
1. The heat generated by the power consumed by the electric heating strip should compensate for all the heat losses of the heat tracing insulation system. 2. Electric heating tapes should have good insulation properties, physical and mechanical strength, as well as resistance to aging. 3. The rated voltage of the electric heating belt should be the same as the operating voltage at which it is used. 4. The electric heating strip can be laid in close contact with the surface of the pipeline and secured firmly ； When the pipeline is flushed for cleaning, and its surface temperature may exceed the maximum allowable temperature for the electric heating strip, it is advisable to install it with a gap. 5. The operating length of the electric heating tape should not exceed its maximum allowable operating length; otherwise, an additional power supply should be connected. 6. Electric heating tapes used in hazardous locations should be equipped with dedicated explosion-proof junction boxes.
The quality requirements for the installation of electric heat tracing include: – The heat generation capacity must be sufficient to compensate for all heat losses. - Electric heating tapes must have good insulation properties, physical and mechanical strength, and resistance to aging. - The rated voltage must be the same as the operating voltage. - It can be laid in close contact with the pipeline for secure fixation ； It can be applied in intervals at high temperatures. - Use a length that does not exceed the maximum allowed length ； An additional power supply is required if it exceeds that amount. - Explosion-proof junction boxes should be used in hazardous locations. .
