Is the nozzle in fusible alloy afraid of freezing?

Best answer: Not afraid of freezing. Fusible alloy nozzle can withstand the low temperature of-30 degrees Celsius. The glass tube of spray head is not filled with water, but a special liquid, which is controlled by various burst temperatures, so it is not afraid of freezing. In order to prevent the pipeline from freezing and cracking, antifreeze is usually added to the fire water, but if the water in the pipeline crystallizes, its volume will expand, resulting in the glass tube bursting under excessive pressure.
