Also, electric heating cable systems are typically used as backup systems when steam is used as the main source of freeze protection. Specific allowances need to be made for tracing water for safety showers and fire protection systems. In order to manage this effectively, various features can be designed into your system such as real-time temperature data, backup operations (in the event of a failure), system failure notifications, wireless connectivity, and more. The controls in these types of systems can be very complicated, as often they are process critical. This will help to determine the right amount of power necessary for the applications so an efficient heat trace system can be designed and supplied. These include pipe size/diameter, liquid temperature/heat loss, number of thermal heat sinks in the run (flanges/valves), and type of insulation. The system design for electric pipe heat tracing applications will be affected by several factors. Using self-regulating electric heat trace alongside an ambient temperature sensing system is the most cost-effective and efficient way to protect your pipes from freezing. One of the most commonly used applications for electric industrial heat trace products is to avoid the freezing of pipes. Also, it’s possible to control the level of heat generation through these wires by altering the wattage of the heat trace cable to work with particular requirements for processing fluid. You can design a customised heat trace system for certain applications by choosing the right type of industrial heat trace cable. ![]() Pipe heat tracing (also referred to as heat tracing) is often used to make sure fluid, process, or material temperatures within pipes and piping systems are kept above ambient temperatures during static flow conditions as well as offering additional freeze protection in specific applications. In this article, we’ll be going into detail on what pipe heat tracing is and how it is used. In serious cases, the build-up of pressure in pipes can result in cracks, or the pipes could even blow up, causing serious injuries to anyone near to the system. If freezing occurs within pipes, it can cause damage to the piping system as a whole. Korea EHT introduced MI (mineral insulated) heating cable for the first time in Korea in 1989.Having a pipe heat trace system is essential for cold weather conditions when the liquid that flows through pipes tend to freeze. For the process of welding the connection between cold lead part, special technology from the expert company is required Because of the series heating method, available usage length must be considered while deciding the model. It also has high heat resistance(800℃).Ĥ.Ělthough it has various advantages, it needs sophisticated design. Because it has seamless form which does not have the joints, its durability is the best among all heating cable products. Recently the outer sheath is produced with drawing method rather than welding method. According to the maximum voltage, it is categorized as 300V, 600V, and 750V rating type. And it’s sheathed with metallic materials.Īccording to the sheath materials, there are Inconel type, Alloy825 type, Stainless Steel 316 type, Coupro nickel type, and Copper Sheath type. The heating element of one (or two) strands are insulated with Magnesium Oxide Powder that has 2600℃ heat resistance character. Its maximum exposure temperature is 260℃. And according to the heating value, there are models of 5, 10, 15, 20 watts/feet (16, 33, 49, 66 watts/meter). As a result, it has the character of PTC (Positive Temperature Coefficient) that increases the resistance and reduces the output as the temperature increases. And its structure leads to the increase of the heating element’s length in each circuit. On site, it reduces the possibility of circuit damage by bending the cable. In this structure, the glass yarn supports the heating elements. It has the advantages of constant wattage heating cable and strengthens the disadvantages. 1 meter forms one zone, and parallel electric circuits are made. ![]() But instead of winding the bare Nichrome heating element itself, glass yarn is winded by Nichrome heating cable first, and they together winds the conductor. Its structure is similar to the constant wattage heating cable.
