2) Anhui heating cable has good flexibility, but it does not allow hard folding. When it needs bending, the bending radius should not be less than 6 times of the thickness of heating cable.
3) It is forbidden to use hard weights for heavy heat cables in Anhui heat trace cables.
4) The Anhui heat tracing cable should be tightly and fixedly attached to the heat tracing pipeline (or equipment) to improve the heat tracing efficiency. Use a special nylon cable tie when fixing the heating cable, and it is strictly forbidden to tie it with wire.
5) The non-metallic pipe shall be provided with a layer of aluminum tape between the outer wall of the pipe and the heating cable to increase the contact heat transfer area.
6) The installation of heating cable should fully consider the possibility of removal of pipeline accessories (or equipment), and the heating cable does not need to be cut off. When the Anhui heat tracing cable is cut or jointed, pay attention to the sealing of the joint.
7) When the heat loss per meter of pipe is greater than the output power of the heat tracing cable per meter, the heat tracing cable can be laid according to the drawings to facilitate disassembly.
8) The pipeline flange is prone to leakage. When winding the heating cable, avoid it directly below.
9) Installation method and fixing of heating cable on pipeline can be carried out according to drawings. The tie material should be chosen according to the temperature of the pipe.
10) After the heat tracing system is installed, the electrical test must be carried out one by one, after which the electrical test must be conducted to check the heating of the heating cable. Only after confirming normality is it allowed to keep warm.
11) Insulation material should be dry. The damp insulation material will not only affect the heat tracing effect, but also lead to corrosion of the heating cable and shorten the service life. The insulation pipe not covered by the outer protection layer should be air-dried and then exposed after construction.
12) After the construction of Anhui Heating Cable System is completed, an obvious electric heat tracing mark should be made on the outer protective layer of the pipeline to remind people to pay attention.
13) When Anhui heat tracing cable is installed, the other end of the bus should be sealed with a matching head cover before one end of the cable is connected to the power supply. The two bus bars must not be short-circuited.
14) When the multi-loop Anhui heat tracing cable is taken out from the same junction box, the busbars must be insulated with insulation sleeves to prevent short circuit of the cables.
15) Each junction box should be sealed to prevent rainwater ingress.
Anhui Electric Heating Cable Installation Precautions
When installing the Anhui Heating Cable, it is important to keep in mind the following: 1) When installing the Anhui Heating Cable, do not pull it on the ground to avoid being damaged by sharp objects. Do not touch high temperature objects and prevent molten slag from splashing on the heating cable.
