BLUTOP Vi joint
Study of the full range of pressure options
During their useful lifetime, water distribution pipelines are subjected to numerous types of pressure, but also the following :
- Day/night time pressure cycles
- Water hammer
- Pressure drops
- External pressure
- Period without pressure prior to commencement of operations
In each of these situations, the joints are subjected to specific types of stress. For this reason all joints for ductile iron pipeline are designated and tested in accordance with strict methods :
In accordance with EN 545 testing : 2007 - 4 tests
PAM’s own specific testing - 4 additional tests
These tests are carried out on both non-anchored and anchored joints, taking into account the full impact of said tests, with a safety factor of 1.5 x PFA + 5 , namely 29 bar, in the case of 16 bar pressure.
Performances
High perfomance level with anchored joints
| DN/OD | Class | PFA | PMA | PEA |
|---|---|---|---|---|
| Allowable operating pressure bar | Allowable maximum pressure bar | Allowable Test Pressure bar | ||
| DN/OD 75 to DN/OD 160 | C25 | 16 | 19 | 20 |
Angular Deflection
| DN/OD | Allowable laid deflection | Pipe end displacement (cm) |
|---|---|---|
| DN/OD 75 to DN/OD 160 (6cm) | 6° | 62 |
BLUTOP joint withstands a maximum angular deflection of 6°.
Range
From DN/OD 75 to DN/OD 160.
