Learn to judge the power and length of silicone heaters

The pipes between the working section, temperature compensation section, and pressure pump and regulating valve are wrapped with thermal conductive adhesive, and the electric heating belt and refrigeration pipe are wrapped axially along the loop inside the thermal conductive adhesive. The thermal insulation layer is wrapped on the outer side of the thermal conductive adhesive, and non-contact flow meters, multiple non-contact color testers, and multiple temperature sensors are installed on the working section. This device relatively lengthens the length of the experimental working section and can be used for long-distance transportation simulation experiments. The increase in the bending radius of the experimental loop neutralizes the influence of centrifugal and centripetal forces on the conveying medium.

The silicone heater can regulate the temperature of the conveying medium and pipelines. Based on the maintenance temperature of the traced system and the maximum operating temperature for accidental operation, select the product with the highest maintenance temperature higher than it. Determine the electric heat tracing scheme and product model based on the power supply conditions, grid load, and the layout, size, and complexity of the heat tracing system. Determine product power and length based on the heat loss per unit length of the pipeline or per unit area of the container. Select the product structure type based on the commonality, explosion-proof or anti-corrosion properties of the application environment. During installation, it is necessary to avoid pits, hidden corners, and other areas where flammable and explosive media may accumulate.

When selecting an electric heating strip, pay attention to its explosion-proof temperature group, which should not exceed 75% of the flash point or spontaneous ignition temperature of flammable media. Do not bend or drag the ribbon cable over long distances on the ground when discharging it. The installation of the heating strip must be completed after all the medium pipeline systems have been installed, and after passing the water pressure or air tightness test, the construction of the insulation layer must be carried out after all the heating strips have been installed, debugged, and the trial power supply is normal. When installing electric heating strips, sharp edges and corners should be polished smooth or covered with aluminum tape to prevent damage to the external insulation layer. In principle, the minimum bending radius of the electric heating strip during installation should not be less than 5 times its thickness.
