High performance self limiting temperature electric tracing tape
More than fifty years ago, since the introduction of temperature limited electric heating technology, the heating industry has made historic progress. This technology is widely used in the antifreeze, insulation, viscosity control, and prevention of condensation and freezing of any process in pipelines, tanks, and containers; The self limiting heating strip contains a heating core composed of a mixture of polymer and conductive carbon black, which forms a conductive path between the two parallel busbars of the entire heating strip. The number of paths varies with temperature, making the heating more uniform.
The product can automatically limit the temperature during heating and adjust the output power with the temperature of the heated body, avoiding high-temperature overheating and burning. The advantage of the product lies in the uniform temperature of the heat tracing pipeline, energy-saving, free shearing, low installation and operation system cost, simple maintenance, and automatic management, which is suitable for more complex pipeline heat tracing.
Principle of Huanrui self temperature limiting technology
01
When the ambient temperature cools, the tube body cools, and the conductive core or fiber undergoes microscopic shrinkage, forming a conductive pathway.
02
When the environmental temperature warms up, the belt body warms up, and the conductive core or fiber begins to expand microscopically, cutting off the conductive pathway.
03
When the conductive core or fiber is fully expanded, the belt becomes hot and can almost cut off all conductive pathways.
Characteristics of Huanrui self temperature limiting technology
Easy installation:
The parallel circuit and flat cable design make the use and installation of the electric heating system very convenient. This system can be freely cut at the project site or overlapped at valves, flanges, and instruments. Quick start: Provide high power output according to demand, and be able to start quickly when the surface temperature of pipelines or objects requiring heat tracing is low.
Low operating cost:
The system can compensate for variables such as heat dissipation and fluctuations in voltage and temperature, providing heat at a lower starting current at a limited time and location. Temperature balance: Due to the fact that the electric heating wire can sense the actual situation of the pipeline and respond, the overall temperature consistency of the system is better
Advantages of multi-layer co extrusion technology:
1. The multi-layer co extrusion technology can make the PTC heating core layer and inner insulation layer wrapped more tightly without gaps, preventing air, water, oil, and impurities from coming into contact with the substrate, reducing the attenuation rate of the heating cable.
2. The buffering regulation of the low voltage anode transition layer significantly reduces the current impact on the PTC core strip, thereby reducing the starting current of the self limiting heat tracing band and extending its service life.
3. Most of the insulation materials on the market cause more or less damage to the PTC heating core, reducing the performance and lifespan of the heating core belt: Huanrui's independently developed insulation materials can completely match the PTO core belt, without any damage to the PTC core belt. Huanrui's products have good weather resistance and UV resistance, and can operate at temperatures ranging from -40C to 140 ° C. At the same time, they have extremely high insulation performance. The insulation resistance of the 100 meter product is not less than 2000M Ω.
The multi-layer co extrusion technology of Huanrui self limiting temperature electric heating strip refers to the process of sequentially observing the low resistance transition layer, PTC heating core strip layer, inner edge outer winding metal braid layer, and outer sheath layer on the conductor surface. Among them, the low resistance transition layer, PTC heating core strip layer, and inner insulation layer are extruded at once, rather than being extruded multiple times using traditional processes
Used for complex pipeline heat tracing
Huanrui self-limiting electric heating strip can quickly respond to temperature changes. When the required temperature is reached, the electric heating strip will automatically reduce energy consumption. At this time, the energy consumption of other products in the market is still very high.
After 1000 cycles of cold and hot cycling tests, the output power of the Huanrui self-limiting electric heating strip remained stable. At this time, the power of other products in the market decreased very quickly
Self limiting temperature standard:
In order to meet the requirements of fast start and energy conservation, Huanrui uses strict self-control standards to measure the adjustment rate of thermal output with temperature changes. The output power of constant power products cannot be adjusted, and other products on the market cannot meet our standards.
The design life at a temperature of 120 ° C and a exposure temperature of 1000 hours of steam sweeping clearance is above 20, and the test results are superior to the design standards. At this time, the lifespan of other products in the market is very short.
Thermal stability at cyclic temperature:
We can ensure the stability of heat output for the heating and cold cycling treatment of Huanrui electric heating products.
After 1000 cycles of cold and hot cycling tests, the output power of the Huanrui self-limiting electric heating strip remained stable. At this time, the power of other products in the market decreased very quickly
Accelerated thermal aging test:
By heating Huanrui electric heat tracing products beyond their rated temperature range, we can estimate their main service life within the rated range.
