TAKING POLYETHYLENE (PE) PIPE TO NEW HEIGHTS....AND NEW DIAMETERS!

Author(s) : Norbert Jansen, Albert Lueghamer 2018 Las-Vegas

Demand for polyethylene (PE) pipe continues to grow on a global basis. The performance properties of this tough, durable piping material are widely recognized by the engineering and design community on a worldwide scale and the range of applications expands. The evolutionary trend in PE piping systems has been very...

TESTING PARAMETERS INFLUENCING THE STRAIN HARDENING MODULUS

Author(s) : E.J.W. van der Stok 2018 Las-Vegas

The effect of eleven different test parameters on the strain hardening modulus was investigated using the Design of Experiments statistical method. The changes in strain hardening modulus due to temperature, tensile drawing speed and the cooling rate after annealing were assessed. The importance of taking account of...

The Evolution of Elastomeric Joints in Plastic Pipe Systems and the use of Long Term Stress Relaxation Testing to Predict Service Life

Author(s) : Julian West 2018 Las-Vegas

Until the late 1950’s, water and sewerage pipe lines used predominantly rigid joints. These were often made from tarred rope and cement mortar. The introduction of ‘flexible’ elastomeric joints allowed angular deflection, transverse shear load and localized pipe deformation without leakage or failure of the...

THE INFLUENCE OF MOLECULAR DESIGN VARIABLES OF BIMODAL HDPE ON THE SLOW CRACK GROWTH RESISTANCE MEASURED BY ACCELERATED METHODS

Author(s) : Cliff Mure, Siddharth Athreya, Dane Chang, Rujul Mehta 2018 Las-Vegas

New generations of PE100 and PE4710 pressure pipe materials exhibit a superior balance of mechanical properties. The slow crack growth performance of these materials measured by traditional tests such as PENT and FNCT can exceed one year. Accelerated test methods, including strain hardening modulus, accelerated FNCT,...

THE TEST METHOD OF METALLIC ELEMENT FOR POLYETHYLENE PLASTIC PIPES OR MATERIALS FOR PIPES AND ITS APPLICATION

Author(s) : Xiaoying Lu, Yujie Wang, Qiang Huang, Chunyan Xu, Guangyu Zhu, Aimin Xiang, Linmei Wu, Yanfang Wang 2018 Las-Vegas

The determination method of metal elements for polyethylene pipes was reported in this paper, the difference in metal elements content between raw materials and recycled materials was analyzed. The results showed that raw and recycled materials in polyethylene pipes were effectively distinguished via metal element...

THE USE OF TEMPERATURE, LUBRICATION, AND SUPPLIED HYDRAULIC PRESSURE IN THE PRODUCTION OF ORIENTED PVC PIPE

Author(s) : Jie Feng, Michael Petr, Jeff Wenzel, Mark Mirgon, Sam Crabtree, Alan Nakatani 2018 Las-Vegas

Through tensile tests, simulated orientation, tribology, and finite element analysis, this study explored the effect of temperature, lubrication and applied hydraulic pressure in the PVC orientation process. It was demonstrated that tight control of these parameters is critical in a continuous PVC orientation process...

THE WORLD'S FIRST CLASS 3 SAFETY RELATED NUCLEAR PE4710 PIPING PROJECT – 10 YEAR REVIEW

Author(s) : Lonnie Corley, Dane Chang, Harvey Svetlik, Matt Brandes, Thomas Musto, Frank Schaaf, David Fink 2018 Las-Vegas

This paper presents a brief overview of a challenging project at the Callaway Nuclear Power Plant where HDPE was utilized to replace degraded steel buried piping in a Safety Related water system. Callaway was the first Nuclear Power plant to obtain NRC approval and successfully place the HDPE piping system into...

TRENCHLESS ADVANCEMENTS IN HDD WITH FUSED PVC

Author(s) : T. R. Marti 2018 Las-Vegas

Horizontal Directional Drilling, or HDD, is now a common technique for installation of PVC pipe. This was not always the case. The fused PVC use in HDD has grown from an initial installation of 500’ (150M) in 2004 to installation lengths over 7000’ (2.14 KM) today. Advancements in connection properties taking into...

UNIMODAL MDPE (PE 2708/PE 80) PIPE MATERIALS SIGNIFICANTLY IMPROVE ABRASION RESISTANCE IN SLURRY FLOW APPLICATIONS

Author(s) : Ashish M. Sukhadia, Wes Long 2018 Las-Vegas

Polyethylene (PE) pipe is a frequent choice for transporting slurry solutions. It has proven to have superior wear resistance than other pipe materials. For example, when carrying fine grain slurries, polyethylene pipe has been shown in laboratory tests to be three to five times more wear resistant than steel pipes....
