Heating method
Thread Content
During the installation of instruments, which areas require heating, and what are the available methods for providing such heating?
Under normal circumstances, instrument heating and pipeline heating are required； Additionally, if the medium in the pipeline tends to condense under operating conditions, separate heating for the instrument can be considered. The types of heat tracing currently available are steam and jacketed heat tracing.
It depends on the specific conditions of the process; pressure transmission pipelines in which the medium is sensitive to freezing or that condense at low temperatures require heating, and instruments whose operating temperature is lower than the ambient temperature also need heating. (The root valve of instruments using flanged capillaries requires heat tracing.) The main methods of heat tracing are steam tracing and electric tracing, which are selected depending on the conditions.

The main methods of heat tracing include steam tracing and electric tracing, which are selected depending on the conditions. If conditions permit, it can also be wrapped in insulating material without adding anything else.
Heating methods include steam heating, water heating, and electric heating. Steam heating is used quite often, but it tends to freeze; after switching to water heating here, the maintenance needs have been greatly reduced.
There are three common types of heat tracing: steam, water, and electricity. Electric heat tracing requires a high initial investment, but it needs less maintenance later on; however, it should be used with caution in areas with strict explosion-proof requirements； Steam tracing is relatively common, but it freezes easily in the north, which is quite troublesome ； Water-based heating won’t freeze, but there is a certain temperature limit~~
