Design life expectancy of 50 years, established by rigorous ‘Accelerated Age Testing’ which subjects product to working pressure at 80°C for 1000 hours.
Wide tolerances permit lower stock holding
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
Main body: Ductile Iron to BS EN 1563 Symbol EN GJS-450-10
Gasket: EPDM compound Grade E to BS EN 681-1, Type WA, WC
Nitrile compound to Grade G BS EN 682, Type G
Captive, non-rotating bolt heads require just a torque wrench to install.
All models accommodate angularity between pipes which allows for normal pipeline movement caused by ground settlement. Couplings and reducing couplings allowing for 6° total angular deflection (3° total on the flange adaptors)
