trace heating การใช้

• Hit-temperature trace heating elements can prevent blockage of pipes.
• Electric trace heating cables are an alternative to steam trace heating where steam is not available or unwanted.
• Electric trace heating cables are an alternative to steam trace heating where steam is not available or unwanted.
• Industrial applications for trace heating range from chemical industry, oil refineries, nuclear power plants, food factories.
• In laboratories, researchers working in the field of materials science use trace heating to heat a sample isotropically.
• They may use trace heating in conjunction with a variac, so as to control the heat energy delivered.
• Trace heating takes the form of an electrical heating element run in physical contact along the length of a pipe.
• If a line becomes frozen because the heating was switched off then this may take some time to thaw out using trace heating.
• Trace heating can also be done with steam, but this requires a source of steam and may be inconvenient to install and operate.
• Self regulating Trace heating cables automatically regulate the amount of heat supplied so that only those parts with temperatures below the set point are heated.
• International standards applied in the design and installation of electric trace heating systems include IEEE standards 515 and 622, British standard BS 6351, and IEC standard 60208.
• This thawing out is done on the three phase systems by using an'auto transformer'to give a higher voltage, and consequently higher current, and make the trace heating elements a bit hotter.
• Snow guards are not the same as heat tape or trace heating systems used to melt snow faster; but these products can be and are commonly used together to offer better protection from sliding snow problems.
• Trace heating may be used to protect pipes from freezing, to maintain a constant flow temperature in hot water systems, or to maintain process temperatures for piping that must transport substances that solidify at ambient temperatures.
• Since smaller-bore pipes present a greater risk of freezing, insulation is typically used in combination with alternative methods of freeze prevention ( e . g ., modulating trace heating cable, or ensuring a consistent flow of water through the pipe ).
• Copper is required in the heliostat field ( power cables, signal, earthing, motors ), receiver ( trace heating, signal cables ), storage system ( circulating pumps, cabling to consumption points ), electricity generation ( alternator, transformer ), steam cycle ( water pumps, condenser fans ), cabling to consumption points, control signal and sensors, and motors.
