PLEASE NOTE:
  • Mass per metre is an approximation only.
  • Vula cannot guarantee the exact mass as listed on this table.
  • Standard sacrificial layers on sewer pipes are: 300 – 1050 ND – 13mm and 1200 ND – 19m
  • Should you require thicker sacrificial layers, this can be manufactured to order. L = All pipes are 2,5metres in length
