- Description
-
- Commodity name: Antifreeze heat tracing system for water treatment pipelines
The winter in the north is cold, the protection and maintenance of water treatment equipment is as important as the correct use method, because the volume of water in the process of solidification and freezing will increase significantly, if the water in the water treatment equipment and pipeline is frozen, it will directly rupture the water treatment equipment and pipeline, resulting in economic losses.
► Application scenarios
The winter in the north is cold, the protection and maintenance of water treatment equipment is as important as the correct use method, because the volume of water in the process of solidification and freezing will increase significantly, if the water in the water treatment equipment and pipeline is frozen, it will directly rupture the water treatment equipment and pipeline, resulting in economic losses.
In order to ensure that the biochemical treatment effect of sewage is good, meet the water quality standards stipulated by the state, and ensure that the sewage treatment process will not be interfered with by the external environment temperature such as climate, it is necessary to use the antifreeze heating system of the water treatment pipeline.
► Antifreeze heat tracing system for water treatment pipelines
The main components of the electric heating system: intelligent temperature control distribution box, self-limiting electric heat tracing, power junction box, two-way junction box, three-way junction box, four-way junction box, terminal junction box, thickened aluminum foil tape, heat-resistant pressure-sensitive tape, temperature sensor, stainless steel cable tie, special distribution box for electric heating, insulation layer, etc.
System Advantages:
1. Cost-effective: The electric heat tracing designed and selected by our company has a long service life, low maintenance rate and high heat transfer rate. The advantages of YATALO self-limiting electric heat tracing: low starting current, low upfront power distribution cost, long service life, low maintenance cost in the later stage, low power consumption for long-term operation, and high heat conversion rate. We pay attention to the quality of each single product and the professional quality of system integration products, so as to achieve the effect of reducing costs and increasing efficiency in the real sense.
2. Safety guarantee: The main performance items of YATALO electric heating product manufacturing standards meet the GB/T19835-2015 standard, and the product materials are made of high-quality materials to ensure that the performance of the electric heat tracing meets the standards, with good thermal stability, low starting current, uniform heating temperature, heating temperature is within the standard range, will not overheat or short circuit lead to heat tracing combustion or burning, long service life, low attenuation of power meter, and high cost of replacement cycle caused by short life.
► 工作原理
The temperature sensor installed on the pipeline will be transmitted to the temperature control instrument in the intelligent temperature control distribution box through the signal cable, the temperature control meter will compare the received temperature with the set temperature, when the current temperature is greater than the set temperature, the electric heat tracing will not work, when the current temperature is less than the set temperature, the electric heat tracing will start working, in order to avoid frequent start-up, a return difference will generally be set, the distribution box can also be connected with the central control room or DCS system by remote communication, and the start and stop of the electric heat trace can be observed and controlled at the remote end.
► 常规选型
1. Tinned copper core wire
2. Conductive Plastics (Heat-Generating PTC)
3. Inner insulation layer (modified polyolefin/LSZH/fluorinated type)
4. Metal shielding layer (metal alloy wire/tinned copper wire)
5. Outer sheath layer (modified polyolefin/PVC/LSZH/fluorinated type)
Maximum maintenance temperature: 65°C±5°C (continuous power on) Maximum temperature: 85℃±5℃ (intermittent power supply) Rated power: 10W/m、16W/m、26W/m、33W/m Rated voltage: 220VAC Minimum installation temperature: -40°C Minimum bending radius: 5 times the thickness of heating cable Flame retardant type: External flame retardant, internal and external double flame retardant Product advantages: Small starting current, low initial power distribution cost, long service life, low later maintenance cost, low power consumption in long-term operation and high heat conversion rate. ► 施工安装
Installation specification steps: check whether the surface of the pipeline is polished smooth and free of burrs and sharp edges, dry and free of dirt; Check whether the paint inside the pipe is dry and the gas has evaporated for more than 3 weeks; Check whether the corresponding heating tracing materials and accessories are consistent with the materials in the design table; Check whether the materials required for construction are in good condition, etc.
Construction and installation points: the installation of electric heat tracing on the pipeline generally adopts the way of straight laying or winding, during installation, every interval of 300-600mm is fixed with heat-resistant pressure-sensitive tape, after the installation is completed, along the direction of the electric heat tracing is covered with a layer of aluminum foil tape, which is used to increase the heating area of the pipeline, the power junction box and the temperature sensor are fixed on the pipeline with stainless steel tape, and the two-way junction box and the three-way junction box can be fixed with heat-resistant pressure-sensitive tape when the temperature is not high. When the temperature is higher than 200°C, it is generally fixed with stainless steel cable ties.
