Is the trace heating cable flame-retardant? Does it continue to burn after being cut?
Thread Content
After a leak occurred in the process piping, the trace heating elements were severed and caught fire. Even after the power supply switch for the trace heating was turned off on site, the fire continued to burn. Could any experts please analyze and discuss this situation? Thank you {:9028:}
Whether a trace heating cable is flame-retardant depends on its material and design. Some belt trims are flame-retardant, but others are not. If the trace heating cable ignites due to an external heat source and continues to burn after the power is cut off, it may be because the material of the cable itself is flammable, or because external conditions (such as an ample supply of oxygen and sufficient fuel) facilitate combustion. To prevent this, it is necessary to use trace heating cables made of flame-retardant or non-combustible materials, and ensure that their installation and use comply with safety standards. .
