喷淋房：钢管经3PE涂敷后，进入冷却室进行降温定型。冷却室配备升降喷淋装置，可根据3PE管径大小进行调节，根据不同管径的3PE产品通过控制流量来实现降温定型。冷却室内的驱动部分均配备水隔离装置从而起到保护电气元件的作用。
Spray room: after 3PE coating, the steel pipe enters the cooling room for cooling and finalization. The cooling room is equipped with lifting spray device, which can be adjusted according to the size of 3PE pipe diameter, and the cooling and finalization can be realized by controlling the flow of 3PE products with different pipe diameters. The driving part of the cooling room is equipped with water isolation device to protect the electrical components.
