- Commodity name: Cold water pipeline anti-freeze tracing system solutions
Cold plumbing systems are closely related to people's lives. In the northern region, the cold weather will bring damage to the cold water piping system at any time, and this damage is undoubtedly fatal for the whole piping system. Therefore, in the design of cold water piping system, must take the accompanying heat preservation measures to ensure that the pipeline in the cold winter can be used normally.
► Application scenarios
The cold water pipe system is closely related to people's lives. In the northern region, cold weather can cause damage to the cold water pipe system at any time, and this damage is undoubtedly fatal to the entire pipe system. Therefore, when designing the cold water pipe system, heating and insulation measures must be taken to ensure that the pipe can be used normally in the severe winter.
Specific application places include 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.
► Pipeline antifreeze heating system
The main components of the electric heating system: intelligent temperature control distribution box, self-limiting temperature electric heating tape, 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. High cost performance: The electric heating cables designed and selected by our company have long service life, low maintenance rate and high heat transfer rate.
The advantages of YATALO self-limiting temperature electric heating cable are: 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. We focus on the quality of each single product and the professional quality of system integration product matching, so as to achieve the effect of truly reducing costs and increasing efficiency.
2. Safety guarantee: The main performance items of YATALO electric heating product manufacturing standards comply with GB/T19835-2015 standards. The product materials are made of high-quality materials to ensure that all performance of the electric heating belt meets various standards, with good thermal stability, low starting current, uniform heating temperature, and heating temperature within the standard range. It will not overheat or short-circuit and cause the heating belt to burn or burn. It has a long service life and low power meter attenuation, which reduces the high cost of replacement cycle caused by short life.
► How it works
The temperature sensor installed on the pipeline transmits the sensed temperature to the temperature control instrument in the intelligent temperature control distribution box through the signal cable. The temperature control meter compares the received temperature with the set temperature. When the current temperature is greater than the set temperature, the electric heating will not work. When the current temperature is less than the set temperature, the electric heating will start to work. In order to avoid frequent startup, a hysteresis is generally set. The distribution box can also be connected to the central control room or DCS system by remote communication, so that the start and stop of the electric heating tape can be observed and controlled remotely.
► General selection
1.Tinned copper core wire
2. Conductive plastic (heating PTC)
3. Inner insulation layer (modified polyolefin/low smoke halogen-free/fluorinated type)
4. Metal shielding layer (metal alloy wire/tinned copper wire)
5. Outer sheath layer (modified polyolefin/PVC/low smoke halogen-free/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. ► Construction and installation
Installation specification steps: Check whether the pipeline surface is polished smooth without burrs and sharp edges, dry and free of dirt; check whether the paint inside the pipeline is completely dry and the gas has evaporated for more than 3 weeks; check whether the corresponding heating tape materials and accessories are consistent with the materials in the design table; check whether the materials required for construction are intact, etc.
Key points of construction and installation: Electric heating tape is generally installed on the pipeline by direct laying or winding. During installation, it is fixed with heat-resistant pressure-sensitive tape every 300-600mm. After the installation is completed, a layer of aluminum foil tape is covered along the direction of the electric heating tape to increase the heating area of the pipeline. The power junction box and temperature sensor are fixed to the pipeline with stainless steel tape. When the temperature of the two-way junction box and the three-way junction box is not high, it can be fixed with heat-resistant pressure-sensitive tape. When the temperature is higher than 200℃, it is generally fixed with stainless steel tie tape.
