50 Years of Pipes made from High Density PE [PE]

Schulte

# 2006 Washington DC

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 pipes under internal hydrostatic pressure at temperatures of between 20 and 80 °C. Consistent continuation of the long term test has shown that even the first pipes to be made of HDPE more than exceeded the former design service life of 50 years. Through intensive material developments, the long term hydrostatic strength ascertained in long-term failure tests on HDPE pipes rated for 50 years' service meanwhile exceeds 10 MPa.

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....

2010 Vancouver : Influence of shock pressure testing on the service life of HDPE piping systems

Author(s) : Ulrich Schulte, Heinz Vogt, Hans-Friedrich Enderle, Dieter Lilge

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...

2004 Milan : HDPE PIPES ARE MORE RESISTANT TO OXIDATION THAN THE OIT INDICATES

Author(s) : U. Schulte

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...

2001 Munich : Multimodal Design of Thermoplastic Pipe Material

Author(s) : Berthold, Boehm, Enderle, Lackner, Lilge, Schulte

The new generation pipe materials PE 100 are now well positioned in the market because of their unusual combination of mechanical properties. Major advantages are high resistance versus slow crack growth combined with superior stiffness. These new PE 100 resins show very high long term hydrostatic strength for...

2001 Munich : Pipeline Systems Made of Plastics Pipes Extruded from PE

Author(s) : Schulte

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...

1998 Gothenburg : Fresh Water Supply System of Nonmetallic Materials for Large Aircraft

Author(s) : Otto, Schulte, Feldmann

The development of a large aeroplane with two decks and a capacity of more than 500 passengers yields numerous problems in structural design, logistics, passenger systems etc., including special requirements for the fresh water supply system. The reliability of this system is very important, especially during long...
