- Commodity name: Anti-freezing heat tracing system for fire-fighting pipelines
The cold water piping system is closely related to people's lives. In the northern region, cold weather can bring damage to the cold water piping system at any time, and this damage is undoubtedly fatal to the entire piping system. Therefore, when designing the cold water pipeline system, it is necessary to take heat tracing and insulation measures to ensure that the pipeline can be used normally in the severe winter.
► Application scenarios
The cold water piping system is closely related to people's lives. In the northern region, cold weather can bring damage to the cold water piping system at any time, and this damage is undoubtedly fatal to the entire piping system. Therefore, when designing the cold water pipeline system, it is necessary to take heat tracing and insulation measures to ensure that the pipeline can be used normally in the severe winter.
The specific application site has underground garage fire protection and water supply and drainage, outdoor water supply and drainage, cooling tower pipelines, municipal water supply and drainage, station fire protection and water supply and drainage, airport fire protection and water supply and drainage, air conditioning cooling water pipes, office building fire protection and water supply and drainage, etc.
► Pipe antifreeze heating system
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.
► How it works
安装于管道上的温度传感器将感应到的温度通过信号电缆输送到智能温控配电箱内的温控仪表上，温控表将接收到的温度与设定温度相比较，当前温度大于设定温度时，电伴热不会工作，当前温度小于设定温度时，电伴热开始工作，为了避免频繁启动，一般会设定一个回差，配电箱还可以远程通讯与中控室或DCS系统连接，可以在远端进行观察与控制电伴热带的启停。

► Construction and installation
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.
