CSA Z662 is the Standard for the use of plastic pipe in Canadian oil and gas pipeline systems. This paper will give an overview of the recently approved revisions to CSA Z662-11 “Oil and Gas Pipeline Systems”, which will be published next year. These revisions include the following : - RCP Requirements for PE pipe, - MRS Design Equation and PE 100, - HDB Design Factor of 0.45, - Plus Performance PE materials, - CRS Methodology, - Polyamide Materials and - Reinforced Thermoplastic Pipe. The paper will discuss the reasons why these revisions to incorporate higher performance plastic pipes were made to the CSA Z662 Standard, and will serve as an introduction to several papers on the use of plastic piping for natural gas distribution in Canada that will be presented at PP XV.

Structural behavior of flexible plastic manholes is very different from rigid concrete products. Although this is state-of-the-art knowledge, no international or EN standard exists on structural design of these products. Therefore, traditional soil models and soil pressure coefficients are usually applied if...
