How To Do Assembly Work Of Fish Cage Bracket, Upright And Tees?
Firstly, do the butt fusion welding work for the tee and upright pipe, the diameter of upright pipe is equal to that of tee. Then, plug the well fished upright pipe into the hole of bracket.
Welding Requirement：
1、Welding should ensure that the section is completely in the middle and the wrong side does not exceed 10% of the wall thickness.
2、The butt temperature should be kept at 210-230℃, and the melting length of the two ends should be 1-2mm
3、Welding parameters: pipe heat absorption time 70-120s, cooling time 10-16min.
Heat Absorption And Cooling Schedule Of PE Pipe:
Wall Thickness mm | Pipe Heat Absorption Times | Maximum Time Allowed For Switch s | Pressurized Cooling Time | Cooling Time min |
＜4.5 | 45 | 5 | 5 | 6 |
4.5-7 | 45-70 | 5-6 | 5-6 | 6-10 |
7-12 | 70-120 | 6-8 | 6-8 | 10-16 |
12-19 | 120-190 | 8-10 | 8-11 | 16-24 |
19-26 | 190-260 | 10-12 | 11-14 | 24-32 |
26-37 | 260-370 | 12-16 | 14-19 | 32-45 |
37-50 | 370-500 | 16-20 | 19-25 | 45-60 |
50-70 | 500-700 | 20-25 | 25-35 | 60-80 |
The cooling time of welded nozzle is generally 10-12 times the thickness of pipe wall. | ||||
