VIKING JOHNSON MAXISTEP REDUCING COUPLINGS
MaxiStep reducing couplings are designed to provide transitions between pipes of different nominal bores simplifying installations when repairing old pipe with new.
All models accommodate angularity between pipes which allows for normal pipeline movement due to ground settlement. Couplings and reducing couplings allow for 6° total angular deflection/
- Design life expectancy of 50 years, established by rigorous ''Accelerated Age Testing'' which subjects product to working pressure at 80 Celsius for 1,000 hours
- A rigorous bolt torque test is completed to confirm that the bolt, end ring and adaptor bosy are capable of withstanding bolt over-tightening to 1.5 times maximum recommended torque
- Wide tolerances
