ASME B31.4 VS CSA Z662

ASME B31.4 VS CSA Z662 by Meena Rezkallah, P.Eng. for engineering Services across canada and USA.

This article focuses on the comparison of ASME B31.4, Pipeline Transportation Systems for Liquid Hydrocarbons and Other Liquids and CSA Standard Z662, Oil and Gas Pipeline Systems. Significant issues which are expected to be the basis of continued discussion include:

  • Increasing the design factor in the US to the Canadian value of 0.80

  • Depth of cover requirements

  • IM requirements.

The liquid pipeline standards in the US do not provide even the minimal level of guidance found in the gas pipeline standards for concepts of strain-based design except for offshore liquid pipelines.

Table below provides a tabulated version of comparisons between US and Canadian liquid pipeline design.
