標準名: A-1620 鋁塑管
俗 稱: 1620鋁塑管
材 質: 鋁、塑料
尺 寸: 1620（內徑16mm，外徑20mm）
重 量: --
常用用途: 常用於總管、分支的冷熱水管 鋁塑管和PPR管常識：PPR管20管是20mm外徑，如果店鋪頁麵寫著20X3.4就是代表20mm外徑（也叫4分管），3.4mm厚度管，同理25*3.5就是25mm外徑，3.5mm厚度的6分管。
客戶問：4分管是哪個管？
小二答：PPR4分管是20管，外徑20mm。
客戶問：PPR熱水管可以當冷水管用嗎？
小二答：PPR熱水用於冷水更好，壽命更長。
客戶問：鋁塑管4分管是多大的管。
小二答：鋁塑管沒有多少分的說法，1216北方很多地區叫4分，1620叫6分。兩廣叫1216為3分，1620為4分，2025為6分。其標準叫法就是直呼標準名，1216鋁塑管就是內徑是12mm，外徑是16mm，1620鋁塑管是內徑16mm，外徑20mm。
