Note:

  • The wall thicknesses for pipe diameters 90mm and below, including the entire class 4 pressure range, are based on a design stress, ós of 10MPa and an overall service (design) coefficient (or safety factor) of C = 2.5 at 50 years.
  • Wall thicknesses for pipe diameters greater than 110mm are based on a design stress, ós of 12.5MPa and an overall service (design) coefficient (or safety factor) of C=2.0 at 50 years.
