Stainless Steel Backing Ring – Table D

When joining two pipes together, it is necessary to ensure prompt alignment to prevent leaks. To enable PVC pipe to be joined together, a backing ring is necessary. Backing rings are typically round, made from either Galvanised Steel or Stainless Steel. Backing rings are also referred to as an anti-extrusion ring or backup ring.

INSTALLATION (Caution) – Since Polyethylene (PE) Pipe Systems are end load bearing, care MUST be taken when connecting pipe of another material to backing rings. To prevent the pull-out of non load bearing joints, read the below installation instructions:

  1. Place the backing flange over the pipe before the stub flange is fused to the pipe.
  2. Clean the matting prior to installation, ensuring they are free from contamination or damage.
  3. To install, ensure the pipework configuration and matting faces align and are butted square prior to bolting up.
  4. The gasket must be centred properly between the two flanges before tightening commences.
  5. Tighten the nuts and bolts progressively and evenly in a diagonally opposite sequence

Bolt Tightening Sequence

When tightening pipe flange bolts the aim is achieve even compression of the PE flange face. The accepted way of achieving this is by progressing through several levels to achieve the final torque value. flanges less than 450mm diameter this progression should be in three stages with the first applying 30% of the final torque, the second stage 60% of the final torque and finishing with the final torque value. For each progression the nuts should be tightened in a diametric sequence to ensure the load is applied evenly.

For large flanges, the recommendation is for four stages beginning with 25% and increasing the torque by a further 25% at each stage. Again the nuts should be tightened in a diametric sequence.
