EN545 Self Restrained Joint Ductile Iron Pipe With Flexible Connection
Restrained flexible joint
Flexible joint in which a means is provided to prevent separation of the assembled joint
With the characteristics of flexible connection and rigid connection at the same time. The joint has excellent anti-extract performance, which especially suit for varied topography and plot slop, and has some adaptation for asymmetric foundation settlement results from inner pressure of pipeline.
The hydraulic test pressure of the ductile cast iron pipes is as follows:
| Nominal diamater (DN) mm | Hydraulic test pressure |
| 80≤DN≤300 | 5 |
| 350≤DN≤600 | 4 |
| 700≤DN≤1000 | 3.2 |
| 1100≤DN≤2000 | 2.5 |
External coating of zinc with finishing layer
The external coating of centrifugally cast ductile iron pipes shall comprise a layer of metallic zinc, covered by a finishing layer of a bituminous product or synthetic resin compatible with zinc. Both layers shall be works applied.
The zinc is normally applied on oxide-surfaced pipes after heat treatment; at the manufacturer’s option, it may also be applied on blast-cleaned pipes. Prior to application of the zinc, the pipe surface shall be dry and free from rust or non-adhering particles or foreign matter such as oil or grease.
