噴淋房：鋼管經3PE涂敷后，進入冷卻室進行降溫定型。冷卻室配備升降噴淋裝置，可根據3PE管徑大小進行調節，根據不同管徑的3PE產品通過控制流量來實現降溫定型。冷卻室內的驅動部分均配備水隔離裝置從而起到保護電氣元件的作用。
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.
