Installation Notes Electric Heating Cable Installation

Heating installation and installation notes

1. Before installation, check whether the heating cable is in good condition and check the surrounding environment so as to adjust it in time.

2. Pipeline: It will need to be installed along the pipe along the cable, laying the length according to the need, leaving allowance for elbows, valves, etc.

3. Tanks: When tanks are installed, they should be installed from the top to the bottom, starting from the top of the tanks, to the bottom of the tanks. This is so that one end of the power supply can be placed on the bottom of the tank for later use. operating.

4, meet the need to thread the place, there must be timely threading. Do not pull the cable directly, especially at the corners, to prevent damage to the heating cable.

5, first from the end of the electric heating cable installation, installation of the terminal junction box, and fixed on the pipe or tank.

6. Adjust the length of the electric heating cable along the pipeline. Reserve the appropriate margin where needed, and attach the electric heating cable to the pipeline. Use a pressure-sensitive tape to fix it roughly. The tank installation is connected to the terminal junction box wiring and fixed at the bottom of the tank. The electric heating cable is flatly attached to the tank, and spirally installed along the tank from bottom to top. Keep the parallel distance between the cables. Use pressure sensitive tape or aluminum foil tape to fix it roughly.

7. When the electrical heating cable is roughly fixed, pay attention to adjusting the length and reserve amount of the heating cable. Due to the fact that the electric cables are laid and reserved along the pipeline during installation, only minor adjustments are required.

8. When it is fixed to the power terminal, connect the power terminal box (there is no electricity at this time) and fix it.

9, install explosion-proof temperature controller and temperature control probe.

10. Use pressure-sensitive tape or tape to fix it accurately. If necessary, use foil tape to wrap all or part of the cable.

11. Ground the metal braid of the heating cable.

12. The power distribution device installed with the electric heat tracing system must be equipped with a leakage protection or air switch to ensure safe use.

13, electricity test electric heating system can operate normally.

14, according to the overall construction progress, install the insulation layer.

15. Suspension of electric heat warning signs and signposts.

Product Description

Detailed introduction: s filling agent for ablating grinding wheel abrasive, which can effectively reduce the grinding wheel temperature during ablation, improve the heat resistance, and prolong the service life of the grinding wheel.

Formation of a protective layer
(1)The reaction absorbing oxygen occurs between 400 and 475 degrees, thereby reducing the oxidation of resin, reducing the oxidation burn of workpieces, and prolonging the working life of grinding wheels at high temperature.

4 FeS2 + 11 O2â†’2 Fe2O3 + 8 SO2
(2) 4 FeS + 7 O2â†’4 Fe2O3 + 4 SO2

400-475 degrees is a limit that the grinding wheel can easily reach. The above reaction creates an oxygen-free and hypoxic environment for the grinding wheel at the micro level, thereby improving the high-temperature performance of the grinding wheel.
Decomposition reaction occurs at 650-degree heat absorption, thereby reducing the working temperature of the grinding wheels.

FeS2â†’FeS + S
(3) It enters the melting state at about 1100 degrees, which becomes a good lubricant to protect the grinding wheel FeS(s)â†’FeS(l).

(4)Sulfur, sulfur dioxide and sulfur trioxide react with the workpiece surface to form FexSy:

Quality:
