Big diameter polyethylene pipes used an important role due to superior performance (Flexibility, light weight, long lifetime and tighten joint) for water and industrial supply to several countries. However according to standard concerned Polyethylene pipes as like ISO4427 we are being used solid wall pipe with too...

As the resistance to notches of the new PE 100 RC materials continuously improves, the classical control methods - as mentioned in the product standards - of PE have to improve consequently. Indeed, the resin compound producers now have pipe qualities with notch resistance far beyond 1000 h. It was necessary to...

Polyethylene pipes are successful worldwide due to the superior performance (Flexibility, light weight, lifetime, tighten joint) for water and sewerage supply. However according to our ISO standard concerned Polyethylene pipes we have to use solid wall pipe with too thick against for internal pressure. The major job...

ISO CD 29561 applies to glass fibre reinforced polyethylene pipes and fittings intended to be used for the conveyance of water under pressure for general purposes, as well as for the supply of drinking water. The pipeline may be buried, above ground, or outside buildings. The temperature of the medium to be...

As polyethylene pressure pipes enter the global marketplace under an ever-wider range of operating conditions, there is increasing emphasis on their rapid crack propagation performance. It is important that both producers and end-users are able to rely on the robustness of the rapid crack propagation test results and...

Since the official introduction of the S4 test in several ISO and CEN standards, different test institutes have achieved experience in the RCP behaviour of polyethylene gas and water pipes. In most cases the S4 test is limited for smaller pipes up to a diameter 250 mm. This paper resumes the results recently obtained...

Although total safety in the gas industry may be an impossible dream, each engineer must definitely use every possible means to come near to this perfection. In view of this objective some gas companies join their efforts for combined research and development in order to improve standards or specifications and...

Plastics pipes and fittings are used in all types of applications in the water, gas, sewer and other industrial applications, where long life (minimum 50 years) is needed.Early applications have already been reported since the year 1935, but the imp0rtar.t growth was after the years 1970. A steady stream of new...

After a water supply crisis due to the age of the distribution system and insufficient sources of water, the Municipal Water Supply Co~npanyof Palermo (A.M.A.P.) decided in 1990 to proceed to the acquisition of a new "Preliminary Project of the water supply for the town of Palermo".Four engineers (Cesare Arici,...

This investigation was initiated because the producers, users and testing institutes of the same PE compound recommended different procedures for butt fusion. The major difference was in the pressure to produce the weld. The difference was obviously reflected in the shape of the fusion bead as shown in Figure 1. The...

This paper describes the test methods to study rapid crack propagation (RCP) behaviour of polyethylene (PE) pipes, including the evaluation of the correlations between different test methods. The test methods concerned are the Full Scale test, the Small Scale Steady State (S4) test, the Small Scale Steady State Scum...
