South America is a region with a fast increase in economic growth and energy needs, and natural gas represents a strategic energy source not only for producers like Argentina but also for net importers like Uruguay and source-differentiated countries like Brazil. The fast development of the economy leads to request of gas from industrial estates requiring medium pressure gas, and in these cases, PE100 pipes that can be used up to 10 bar pressure are a winning alternative to steel pipes, pushed by technology transfer from the successful European experience and the economic value provided to endusers. Detailed case studies are presented and analyzed in Brazil, Argentina and Uruguay. In al these cases, PE100 / SDR 11 pipes have been produced with Eltex® orange material and installed for service pressure from 4 to 10 bar to serve both industrial and domestic users. A common feature is represented by the adoption of imported raw material combined with local production of pipes. The end-users have imposed the use of orange PE100, which comes from the same production units used by major European gas companies and guarantees a track record of test and experience in all installation and use conditions. The adoption of orange PE100 results in safe design of a perennial network combining asset management, safety and performance; and demonstrates the validity of a global model where gas industry across the world share the same needs and the same solutions to the benefit of their customers. This global supply to gas companies allows the material producer to offer dedicated assets with full leverage of quality and guarantee. The need for and the availability of natural gas is increasing in South America, together with the desire to reduce carbon dioxide emission and to preserve oil resources. We believe that plastic industry and pipe producers have an important stake in this future providing that we continue to act responsibly towards final consumers and to commit on safety and quality.

This paper looks at the origin of the 10% allowable scratch depth rule for polyethylene (PE) pressure pipe developed in 1971 and research that has been performed over the years since its inception to determine the validity of this rule. The 10% rule has been used by natural gas pipeline operators since the 1970’s to...

The CRS (Categorized Required Strength) concept was developed within the ISO pressure rating system to provide more flexibility to the design engineer. One of the major uses of CRS is to provide a design basis of 100 years for plastic piping applications. With the CRS concept plastic pipe can now have a design basis...

ISO MRS and ASTM HDB rating systems have been successfully used for more than four decades in Europe and North America. MRS differentiates well the three generations of HDPE materials by classifying them as PE63, PE80 and PE100. However, HDB classifies all three generations of HDPE as only one PE 3408. When...
