Continuous development and innovation in the production of plastic pipes made by high density polyethylene (HDPE) has enabled the industry to produce much larger diameter systems than ever believed possible. The enablers for production of such large plastic pipes are three main pillars: continuous innovation of plastic piping raw materials with improved properties, advances in extruders and other equipment developments as well as value- added engineering. This has meant that plastic pipes have become the piping of choice for usage in industrial, municipal and infrastructure works, such as water distribution and transmission, storm water management and sewage.
Especially in the Middle East governments and industries have continued to invest, knowing that low labour costs and low feedstock and material costs, would ensure that they remained competitive. Also, many large water and wastewater projects have been continued for the desalination of sea water, wastewater treatment or water recycling, to provide improved water and sanitation for the growing population. All these projects require large diameter pipes and in many of these countries they have had the confidence to break with tradition and choose thermoplastic pipe materials rather than the conventional ones: such as steel, ductile iron or concrete.

In PPXX, a technology was presented for the first time that could bi-axially orient polyolefin pipes. With this technology, it is possible to prepare pipes that have a performance far beyond the standard ones. One approach to achieving this performance is via a continuous in-line process. To optimize the in-line...

In March 1999, a project report on the performance of buried Thermoplastics pipes was published by TEPPFA /1/. In the report, deflection and strain data on buried pipes were analyzed and compared with calculation results from several well-known static calculation models in use in Europe. Pipes were installed to...

The required wall thickness for a fully fused HDPE water main subject to an earthquake induced lateral spread is addressed in this paper. The water main is assumed to be buried via cut and cover (i.e., open cut with typical burial depths in the 2 to 15 feet range) procedures and any laterals have small diameters. For...

The Notched Constant Ligament Stress test (NCLS test, ASTM F2136)[1] is a test method that measures the slow crack growth in High Density Polyethylene. The NCLS test requires a notch on all test specimens to act as a stress concentration at that point so crack propagation can be easily predicted and studied. In...
