Heating issue
Thread Content
There is a 2\" pipeline that requires heating to maintain a temperature of 0°C. The coldest temperatures in the northeast can reach minus 30 degrees Celsius. The length of this pipeline is around 1200 meters. Currently, hot water heating and electric heating are being considered as options for heating; which method is better? Additionally, there are no hot water pipelines in the pipe rack, so one would need to be installed. How should the load requirements be taken into account?
Electric heating is recommended for the outer pipe gallery, as it allows for precise temperature control, keeping it at 0 degrees. The heat tracing effect of water is relatively inferior to that of electric heat tracing
Electric heating is recommended; it’s easy to install and there’s no need for separate water pipes
If it is a flammable or explosive material, electric heating is not recommended
If it has no impact on the material, electric heating is still the reliable option. Steam is not required; maintaining a temperature of 0 degrees is possible without steam – one water circulation is enough to provide heat. However, it’s not possible to keep the temperature at exactly 0 degrees, and the circulation stops after a while. In the weather conditions of the northeast, temperatures change rapidly. There are many types of electric heating elements, such as heating wires and heating strips, with varying prices and quality levels; simply choose one that suits your needs
Are the maintenance costs for electric heating high? If it gets damaged, replacing it is very troublesome.
Choose a better supplier; electric heating is actually quite stable, while water heating poses a risk of freezing at minus 30°C
Electric heating is recommended; it’s simple to install. At 0 degrees, it only needs to be used for one winter. Although winters in the northeast are quite long, electric heating is still the better choice
Electric heat tracing: Our factory has been using it for five years without any problems
I was a bit panicked when I suddenly saw your message. I work at an acetylene plant, and there’s a point on the main acetylene pipeline where water needs to be drained – the gas contains moisture, and this drainage is necessary on an hourly basis. Additionally, electric heating is used to prevent freezing. It’s really scary!
