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.
1. Clean the dirt on the surface in time
No matter leather shoes or leather clothes, they will be contaminated with dirt and dust as long as they are used. Therefore, they must be cleaned up every day after use. This can also prevent some dirt from staying on the leather for a long time, making it more difficult to clean the leather. When cleaning the surface, white vinegar can be used to mix with water, and then a cloth can be dipped on the leather to wipe off dirt and dust. If the dirt is serious and there is no proper detergent around, please send it to a professional organization for maintenance immediately.
2. Choose the right leather oil
If it is made of genuine leather, you can choose natural animal oil, such as mink oil or salmon nourishing oil, which can help maintain leather. Different brands of animal oil have different absorption and ductility. For example, mink oil is cheap and easy to use, but it is difficult to push evenly, and the absorption effect is poor. In addition, it is not recommended to choose leather oil containing wax. Although it will be very shiny when smeared, excessive wax will affect the air permeability and shorten the life of leather.
3. Small wear can be repaired naturally
If there are some small scratches on the leather, you can use your fingertips, palms or cotton cloth to gently and slowly wipe, dip a little leather oil, and push along the scratches to slowly eliminate the small scratches.
