What are the principles and advantages of electric heat tracing?
Nov 14, 2024
Basic introduction:
Electric heat tracing is an effective pipeline insulation and antifreeze solution, which has been widely used. Its working principle is to dissipate a certain amount of heat through a heat tracing medium, and supplement the loss of the heat tracing pipeline through direct or indirect heat exchange, in order to achieve the normal working requirements of heating, insulation or antifreeze.
Electric heat tracing is a uniform heat release along the length of a pipeline or over a large area of the tank volume, which is different from electric heat tracing where the heat load is highly concentrated at a single point or over a small area; Electric heating has a small temperature gradient and a long thermal stability time, making it suitable for long-term use. Its required heat (electric power) is much lower than that of electric heating.
Advantages:
(1) The electric heat tracing device is simple, produces uniform heat, has accurate temperature control, and can be remotely controlled to achieve automated management.
(2) Heat has explosion-proof, all-weather working performance, high reliability, and long service life.
(3) Electric heat tracing has no leakage, which is beneficial for environmental protection.
(4) Save steel: It does not require the one to two heat tracing pipelines required for steam tracing.
(5) Save insulation materials.
(6) Save water resources, unlike boilers that require a large amount of water every day.
(7) Electric heat tracing can also solve the problem that steam and hot water heat tracing are difficult to solve.
(8) Electric heat tracing design has a small workload, easy and simple construction, and low maintenance workload.
(9) High efficiency, can greatly reduce energy consumption.
Summary:
Electric heat tracing is the only new generation strip constant temperature electric heater that can automatically limit the temperature during heating and adjust the output power according to the temperature of the heated object without any additional equipment; It can be cut short or extended within a certain length range, suitable for temperature control, heat tracing, insulation, and heating of pipelines, equipment, and containers, especially when materials are prone to decomposition, deterioration, crystallization, condensation, and freezing. It has a wide range of applications in the production and processing of petroleum, chemical, power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline products, and other sectors. It is a technological development direction that replaces steam and hot water tracing.
