安裝要點INSTALL IMPORTANT POINT1. 管材與管件連接均應采用熱熔連接方式,與金屬管道可用法蘭連接2. 熱熔連接施工必須使用質量可靠的熱熔機具,以確保熔接質量,便攜式熔接工具適用于dn<63mm 管及系統最后連接,臺式熔接機適用于dn75&160mm 管預裝配連接。3. 熱熔施工在加熱和插接過程中不能轉動管材和管件,應直接插入。4. 熔接操作技術參數
| 管材外徑(mm) | 熔接深度(mm) | 加熱時間(s) | 插接時間(s) | 冷卻時間(min) |
| 20 | 14 | 5 | 4 | 3 |

| 40 | 21 | 12 | 6 | 4 |
| 50 | 22.5 | 18 | 6 | 5 |
| 63 | 24 | 24 | 6 | 6 |
| 75 | 26 | 30 | 10 | 8 |
| 90 | 32 | 40 | 10 | 8 |
| 110 | 38.5 | 50 | 15 | 10 |
| 160 | 55 | 80 | 30 | 20 |
注: 若環境溫度小于5℃, 加熱時間應延長50%.5. 連接后須經施壓驗收后方能封管及使用。 1. The connection of pipe and fittings is hot melt.Flange is used to connect the steel pipe.2. During hot melt connection use welding machine.The quality of welding machine must be guaranteed.To make sure the quality of connection.The portable welding machine applied to the final connection of the pipe and system of dn<63mm.The desk-mounted welding machine applied to the preframe connection of the pipe of dn75-160mm.3. During heating and peg graft,we can’t move the pipe and fittings.We should insert them directly.4. Welding technical parameters
| OD(mm) | Welding depth(mm) | Heating time(s) | Welding time(s) | Cooling time(min) |
| 20 | 14 | 5 | 4 | 2 |
| 25 | 15 | 6 | 4 | 2 |
| 32 | 16.5 | 8 | 6 | 4 |
| 40 | 18 | 12 | 6 | 4 |
| 50 | 20 | 18 | 6 | 4 |
| 63 | 24 | 24 | 8 | 6 |
| 75 | 26 | 30 | 10 | 8 |
| 90 | 32 | 40 | 10 | 8 |
| 110 | 38.5 | 50 | 15 | 10 |
| 160 | 55 | 80 | 30 | 20 |
TIP: The welding time should delay 50% if the working temperature below 5 ℃。5.After the pressure testing we can close the pipe and use.
