Field failures in PE Gas Pipes - Analysis versus Lifetime Prediction [PE]

# 1992 Eindhoven

Eight excavated HDPE pipes of the 1st generation along with 3 modern PE types have been investigated. Comonomer content as a function of molecular weight of the old HDPE pipes appeared to be nonoptimal with respect to the modern PE types. Further unwanted effects in the old pipes were  : particles, oxydation, inhomogeneity. Premature failures were due to previously unexpected effects of external point loadings.

DETERMINING THE RESIDUAL QUALITY OF PE PIPES USING THE STRAIN HARDENING TEST

Author(s) : Ernst van der Stok, Frans Scholten 2016 Berlin

Samples machined directly from pipe show that orientation has a large influence on the strain hardening modulus. No effects arising as a result of residual stresses were found. Samples machined in the axial direction from a hydrostatic pressurised pipe showed no effect as a result of this mechanical degradation. For...

PREDICTING THE LIFETIME OF PE50 GAS PIPES UNDER POINT LOADING

Author(s) : Frans Scholten, Ernst van der Stok 2016 Berlin

The residual quality of first generation PE50 gas pipes, installed in Netherland between 1961 and 1979, is still remarkably good. The only premature failures of a few PE50 pipes were exclusively caused by point loads. When under point loading, they started failing in practice after 8 to 26 years, in a brittle manner....

RESIDUAL QUALITY OF EXCAVATED UPVC GAS AND WATER DISTRIBUTION PIPELINES

The current condition of 35-50 years old uPVC main (110 mm) and service (32 mm) pipes for gas and water distribution was assessed. From 27 excavation sites in total about 400 segments of 1.2 meters length each were tested using many techniques. The K-value (average molecular weight) of the PVC, the degree of gelation...

THE EFFECT OF RESIDUAL STRESSES AND EXTERNAL EFFECTS ON THE FRACTURE BEHAVIOUR OF PVC PIPES

This paper describes falling-weight tests as a first step towards determining the effect of residual stresses on the fracture behaviour of old PVC-U gas pipes at impact. Results showed that the level of surrounding pipe support, the quality of the material and the diameter of the striker had a major effect on the...

Designing Against Rapid Crack Propagation in PVC Water Pipes

Author(s) : Frans Scholten, Ernst van der Stok, Jan Breen 2014 Chicago

Very occasionally PVC-U water pipes suddenly fail due to a long brittle crack with a length of many meters which propagates with the speed of sound along the pipe and causes extensive water loss. This phenomenon has been recognized as Rapid Crack Propagation (RCP). The conditions under which RCP can occur are an...

Energy-to-Failure to Assess the Quality of Electro Fusion Joints in PE Pipes

Author(s) : Frans Scholten 2014 Chicago

When electro fused joints in newly installed PE100 pipelines are tested using the Peel test (ISO 13954 [1]) they too often fail in a brittle manner. Contamination in the interface between the surfaces to be fused is usually the cause. About 77 % of the contaminants in 39 cases of brittle test bars could be identified...

Two Complementary Tests to Determine the Quality of PE 100RC

Author(s) : Ernst van der Stok, Frans Scholten 2014 Chicago

The Strain Hardening (SH) test and the Point Load Test (PLT) are two complementary tests designed to determine the quality of PE 100-RC. The SH test is a resin test, whereas the PLT is a pipe test. The SH test is a tensile test performed at 80 °C. Extensive research on the SH test has been conducted and published in...

PLASTIC PIPEWORK FOR GAS IN BUILDINGS AND THE CONSEQUENCES OF FIRE

The application of plastic pipework for gas inside buildings is still restricted by national laws or local regulations in many countries, while other countries allow this application. The exclusion of plastics is in the main based on the supposed fear of the impact of a fire on the pipework and the escape of unburned...

STRAIN HARDENING TESTS ON PE PIPE MATERIALS

Author(s) : Van der Stok, Scholten 2012 Barcelona

The Strain Hardening (SH) test developed by Kurelec et al. has been applied to a variety of PE pipe and resin materials. The clear trend in the strain hardening modulus, of first, second and third generation PE pipe resins and PE100 RC pipe resins, illustrates the large progress in resin quality during the past four...

A mathematical model was set up to assess the equilibrium gas pressure in the annulus of the reinforcement layer of an RTP pipe. This is done by using the theory of gas permeation, ruled by Fick's Law and the theory for a temperature gradient over the pipe wall, ruled by Fourier's law. The model allows calculating the...
