  • 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.
  • Extensive range is available in sizes DN40 - DN300.
  • 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).
  • A rigorous bolt torque test is completed to confirm that the bolt, end ring and adaptor body are capable of withstanding bolt over-tightening to 1.5 times maximum recommended torque.
Pipe Materials
ABS Asbestos Cement Cast Iron Concrete Copper Ductile Iron GRP HEP30 PE PVC Stainless Steel Steel

PE*Due to the flexible nature of the plastic pipes, a close fit Stainless Steel internal support liner is required when PE Pipe or thin walled PVC is used to make a repair to prevent excessive pipe deformation which can occur when a coupling or flange adaptor is installed.
