It is critical then to have a system in place that would keep the liquids flowing within the pipes at desired temperatures.Ī heat trace system essentially does that and is one of the most reliable ways to control temperatures in the process pipes. However, for process industries that handle liquids, this phase change is a problem.ĭuring cold weather conditions, liquids are likely to freeze, blocking or restricting the flow within the pipes. How to Design The Perfect Heat Trace SystemĪ liquid has a unique property that allows it to thicken and become solid at lower temperatures. In other words, these traces can automatically regulate the current flow based on the outside temperatures. Modern-day heat traces are made from polymers that are self-regulating. In extreme cases, the pressure build-up within the pipes can lead to cracks, or the pipes might even blow up, causing severe injuries to people working near the processing system.īy using a Chromalox's heat trace system, we can keep the pipes warm even when the surrounding temperatures plummet. To prevent heat loss and protect heaters from moisture and corrosion, wrap them with fiberglass insulation. Do not use electrical tape, duct tape, metal bands, or wire. As discussed earlier, freezing within the pipes can damage the entire piping system. Use fiberglass tape or heat-transfer putty to install them directly on surfaces that are free of dirt, grease, and rough edges. Heat trace system is necessary for cold conditions where the liquid flowing within pipes are prone to freezing. It is also possible to control the amount of heat generation through these cables by varying the wattage of the cable to suit particular processing fluid requirements. You can design a customized heat trace system for a specific process application by selecting the right type of cables for the traces. These paths are made up of a resistive element that heats up when electricity passes through it. Installation is quick, simple and requires no special tools, knowledge or skills.A heat trace system is a set of paths lined along pipes or vessels. A complete range of standard power connection kits, splice kits and tee splice kits are available to minimize power supply points and simplify cable routing on even the most complex piping systems.ĪutoWatt Xtra may be cut to length and terminated on site so installers may use only what is needed and are able to save and store extra cable for future installations. With power ratings up to 30 watts/ft, AutoWatt Xtra heating cables are well suited for use on large diameter pipes with high levels of heat loss.
