In many parts of rural developing Asia and even some parts of Africa, sewerage from households is often discharged directly to the surrounding. This unfortunate fact means that many waterborne diseases such as cholera, dysentery and typhoid continue to afflict these communities. Numerous efforts from governments,...

Molecularly oriented polyvinyl chloride (PVC-O) pipe has been found to withstand large ground deformation during seismic events without damage. The properties of PVC-O pipe that support this performance have been investigated in a multi-year testing program undertaken at the Geotechnical Lifelines Large Scale Testing...

This work presents the development of the Full Length Tensile Test (FLTT), a method that enables an objective judgement of welding quality of electrofusion welds by measuring the energy to break (J/mm2 ). In this way a brittle, ductile and transitional mode failure can be differentiated without subjective visual...

Normal High Density Polyethylene (HDPE) is commonly used as the fluid contacting element, or the “inner-liner”, in Reinforced Thermoplastic Pipes (RTP) and steel pipes up to 65 ºC. Through a modification of the HDPE polymer matrix, by adding nanoparticles, the E-modulus can be increased. Research shows that...

In today’s world a lot of energy is wasted. More than 50 % of the energy is lost on its way to the customer. The fundamental idea of modern district heating is to recycle heat that otherwise would be lost and to use renewable sources to heat homes. In other words: a market place for green heat that reduces...

World wide the MLFC pipe market is growing especially the PVC MLFC pipe market. Standards are established first in Europe, Australia, then the America’s, Japan and recently Asian countries are recently following. The main driver using MLFC pipe is reducing the costs of pipe by using less (virgin) material with a...

With a new and innovative catalyst concept it is possible to produce a bi-modal PE-RT Type II material with excellent properties in a single reactor process. The catalyst is based on two different metallocene components, whereas one component doesn’t incorporate any co-monomer and the other component shows a typical...

To take the advantages of the excellent properties of fiber-reinforced components even more economically and industrially, new ideas to implement these potentials are in demand. Only with the introduction of fibers in a plastic matrix, the elastic behavior is changed towards to higher stiffness, strength and impact...

Applications at elevated temperatures like cable conduit pipes for high voltage cables, pipelines used in oil industry or in industrial plants offer new possibilities for PE but additional requirements in such applications have to be taken into account. Long term experience in using PE100 pipes with respect to easy...

Applying scientifically well established and investigated linear fracture mechanic methods (LEFM) the kinetics of the slow crack growth (SCG) on polypropylene layers and coextruded interfaces on multi-layer-pipes could be investigated. Taking effects of ageing and stress relaxation during the service lifetime into...

Rigid PVC (PVC-U) is a well-established material for pipe systems for drinking water, with use dating back to the 1930s. In order for PVC-U to be used in drinking water systems, manufacturers must comply with all of the relevant regulations. These include self-assessment systems, where manufacturers demonstrate that...

The paper offers an overview of systems and components for efficient pipe extrusion, particularly for larger and thick-walled pipes. It introduces several possibilities for lower melt temperatures and internal pipe cooling. Together these systems can significantly reduce sagging and cooling length needed in the line....

PVC-O is the accepted pipe solution for the future. Worldwide, more and more countries go in the direction of PVC-O. The main applications for PVC-O at this moment are potable water, wastewater, irrigation and gas. PVC-O is produced for many years from the 80’s until 2007 the sizes were in majority small (mainly...

An overview of stabilizer systems for PVC pipes had been given at the last Plastics Pipes conference (PPXVII), detailing which technologies are used around the world. This presentation aims to give an update upon technology changes (replacement of Lead stabilizers by Ca-based stabilizers, situation of Tin stabilizers)...

The urgent diversion of a river through a rapidly constructed pipeline was required to avert a power supply crisis to the state of Victoria. In early June 2012, the Morwell River surged and a levee collapsed allowing the river to flow directly into the open cut coal mine which supplies the Yallourn power station. The...

Managing aging pipeline infrastructure is an important part of overall pipeline risk management. The critical risk management questions for an aging infrastructure are: how quickly should replacement occur and what parts of the system should be prioritized for replacement. To answer these questions it is necessary to...

A new methodology has been developed to validate the performance of polyethylene piping materials in potable water applications. The methodology is based on several research programs which examined a standardized accelerated test methodology (ASTM F2263 Standard Test Method for Evaluating the Oxidative Resistance of...

The industrial sector has traditionally used metal pipes for transporting a wide variety of chemicals and highly corrosive liquids. When metal pipes are exposed to aggressive media, their lifetime is considerably reduced. Polyethylene pipes, have demonstrated since the 1950s to be a safe, reliable and cost effective...

Producing PVC is a competitive market. Unless special products are produced like larger sizes or OPVC, the competiveness is important. Therefore the real issue becomes the saving of cost in producing pipe from PVC. There are many ways of saving costs and that issue must be considered in production companies making...
