During the cold winter, the temperature gradually decreases. The oil refining of petrochemical enterprises follows the principle of "not freezing a piece of equipment or freezing a pipeline", and does a good job in
Cov cuab yeej yog tiv thaiv - khov thiab tiv thaiv - condensing kom ntseeg tau tias txhua yam khoom siv tuaj yeem muaj sia nyob rau lub caij ntuj no yam nyab xeeb.
Nyob rau lub caij ntuj no, vim huab cua txias heev, ib puag ncig sab nraud rau kev ua haujlwm ntawm cov khoom siv ntawm qhov chaw yog hnyav heev. Tsis tsuas yog cov roj hnyav yooj yim rau condense vim nws qhov chaw txias txias thiab siab viscosity, tab sis kuj
The operating condition of the external instrument will also become fragile in winter, and it is easy to "catch a cold" and fail. Various factors will affect the safe production in winter.
Cov pa tracing ntawm cov roj kav dej hnyav, cov cuab yeej siv, lub hnab lub cev qhuav dej thiab lwm qhov chaw tau ib txwm ua tus thawj coj ntawm kev tiv thaiv - khov thiab tiv thaiv - ua haujlwm hws.
With the passage of time, steam tracing has been unable to keep up with a series of higher requirements for pipeline antifreeze, pipeline heat tracing and insulation, so steam tracing has gradually faded out of people's sight.
In addition, turning to electric heat tracing has entered people's field of vision in its unique way. Explosion-proof electric heat tracing pipeline insulation technology acts in the field of chemical pipeline heat tracing, using electric energy
As a starting energy, the heat dissipation is balanced and long-lasting, and it can be used when it is powered on. There is no industrial "three wastes" and the safety is very reliable. There is no so-called "running, risking,
Kev txhawj xeeb ntawm cov dej ntws tawm thiab xau, thiab tus nqi yuav luag tsis ua haujlwm kuj yog ib qho ntawm cov laj thawj tseem ceeb rau kev tawg - pov thawj hluav taws xob cua sov cable los hloov cov cua sov.
