Characteristic 

1, the elbow runner smooth transition, reduce the runner resistance, ensure the smooth flow of fluid
2, accurate machining, diameter and Tube diameter matching
3, the welding port is straight, no burr
4, manual or automatic welding
5. Electrolytic polishing of the runner with surface roughness up to Ra0.25um(10uin)
6, the Tube wall thickness is uniform, improve the repeatability of welding
