During the cold winter, the temperature gradually decreases. The oil refining of petrochemical enterprises has always followed the principle of "not freezing a piece of equipment or freezing a pipeline", and has done a good job of anti-freezing and anti-condensation of equipment to ensure that each equipment can survive the winter safely.
In winter, due to the severe cold weather, the external environment for on-site equipment operation is very harsh. Not only is heavy oil easy to condense due to its high freezing point and high viscosity, but also the operating conditions of outdoor instruments will become fragile in winter, and it is easy to "catch a cold" and fail. Various factors will affect the safe production in winter.
The steam tracing of heavy oil pipelines, instruments, dehydration bags and other parts has always been the protagonist of anti-freezing and anti-condensation work. However, with the continuous progress and passage of technology and time, steam tracing has not kept up with people's expectations for anti-freezing of pipelines, heat tracing and insulation of pipelines. A series of higher requirements, so steam heat tracing began to gradually fade out of people's sight, and electric heat tracing came into people's field of vision in its unique way. The explosion-proof electric heat tracing pipeline insulation technology is used in the field of chemical pipeline heat tracing. Electricity is used as the starting energy. The heat dissipation is balanced and lasting. , dripping, leakage' worries, almost zero operating cost is also one of the main reasons for explosion-proof electric heating cable to replace steam heating.
