Polyethlyene, Pipes, Buttfusion, Joining, Testing Several well established procedures are used for butt fusion welding of PE pipes globally. The most widely used are the European Single Pressure, UK Dual Pressure, and the USA High Pressure procedures. In the future it may be possible to rationalise these procedures. Materials and machinery developments are resulting in an increasing size range of pipe. Confirmation of the appropriate test methods is required to assure weld quality, to fully understand the properties of the welds, and to confirm the suitability of the fusion procedure used for such pipes. The PE 100+ Association established this project to evaluate welds in large diameter thick walled pipe. The results of this programme are discussed and conclusions made.

In order to protect the Austrian lakes effectively against the discharge of effluent, a 13 km long pressure pipeline made of high density polyethylene was laid on the bottom of Lake Ossiach back in 1971. The DN355 to DN200 pipes were produced from a first generation HDPE-compound. The classification would have been...

Plastics piping systems are specified against a relevant standard, giving dimensions, essential performance requirements, the design basis for pressure rating, and testing to prove fitness for purpose, giving the end user the confidence to use these systems. The plastics pipes industry has successfully developed...

Traditional piping materials e.g. metals are becoming outdated due to their high weight, difficult handling and questionable performance over time. These are only a few of the reasons why plastics have rapidly become the preferred pipe material over the last few decades. PP-RCT (PolyPropylene Random Crystalline...

Corrugated polyethylene drainage pipe has been used for agricultural drainage in the Midwestern United States for approximately forty years. The increased worldwide demand for corn and soybeans has triggered an increased use of fertilizers and drainage systems by the producer. This combination of these two yield...

The completion of a pressure test is mandatory for all new pipe systems. Its purpose is to demonstrate the overall leak-proof condition of the system. In the course of this test, HDPE pipes of SDR 17 class are exposed to high stress loads. In an extensive test programme, all failure mechanisms observed in long-term...

Kungsors Plast AB, in co-operation with Borealis, has pioneered the underground plastic piping for petrol filling stations with the first polyethylene piping used by Shell Sweden in 1981. The retail sector with petrol filling stations has used PE-based underground piping since the early 1980s. With increased awareness...

After the discovery of the low-pressure process for the production of polyethylene with the aid of Ziegler catalysts, only another year went by before pipes were being extruded in highdensity polyethylene. In the same year, at the end of 1954, Hoechst had already begun to carry out long-term failure tests on HDPE...

There are three factors that can influence the service life of plastics pipes: mechanical overloading, environmental stress cracking and degradation caused by oxidation at high temperatures. This article deals primarily with the degradation that occurs during processing at high temperatures and also – as an...

Design of pipe systems for lifetimes in excess of 100 years depends on accelerated testing of pipe at different temperatures, and standard extrapolation methods for assessment of the minimum required strength. However resistance to slow crack growth is an essential parameter to take into account for the development of...

Design of pipe systems for 50 year lifetimes depends on accelerated testing of pipe at different temperatures and standard extrapolation methods for assessment of whether the minimum required strength is achieved. Further acceleration is used in the notched pipe test (NPT), which is a medium term (up to 1000 hour)...

Lifetime expectations play a major role when selecting materials for pressure pipes. Information on the service life of a piping system made of polyethylene can be gained from the creep rupture tests at various temperatures being evaluated by standardized extrapolation methods (ISO/TR 9080). With the help of test...
