High performing polyolefin materials for demanding applications like solar absorbers

Author(s) : Stubenrauch Kurt 2012 Barcelona

High performing Polyolefins, in terms of mechanical strength and thermal stability, can contribute to an interesting property profile and aid cost reduction in order to aid further growth of renewable energy systems. Cross-linked Polyethylene (PE-X) is discussed in the group of polyethylene, and PP-RCT (Random,...

High Temperatures on PE Pipes for Water Supply Pressure Verification

Author(s) : Chen Zenggui 2012 Barcelona

For PE pipes for water supply installed in the summer, the pipeline’s temperature under the sun exposure can influence the properties of the pipe. If you carry out the pressure tests directly, it can result in damage to the pipeline. So we conducted a detailed analysis and research on the influence of exposure to...

High Thermal Conductivity Polyethylene Pipe

Author(s) : Xia Chengwen 2012 Barcelona

Composites of HDPE/graphite were prepared through blending high density polyethylene (HDPE) with surface activating treatment graphite by self-made compatibilizer and titanate coupling agent. It was studied that the kinds of matrix resin, coupling agent, compatibilizer and graphite particle size and its content...

HOW CPVC INDUSTRIAL PIPING SYSTEM ENTERED NEW APPLICATIONS IN INDIA

Author(s) : Manoj Dhar 2012 Barcelona

 

HOW MUCH RECYCLED PVC IN PVC PIPES?

Author(s) : J.Fumire and S.R.Tan 2012 Barcelona

This paper demonstrates the excellent recyclability of rigid PVC and the strong possibilities of incorporating recyclate into foamed PVC pipes. Calculations show that it is the availability of rigid PVC recyclate, partly due to the long service lives of PVC pipes, which is the limiting factor in further extending the...

IDENTIFICATION OF THE PE RESINS OF THE DISTRIBUTION NETWORKS BY MEANS OF THE DSC-SIS TECHNIQUE APPLIED ON MICRO-SAMPLING

Author(s) : Gueugnaut Dominique, Boujlal Adil, Rousselot Denise, Bouaffre Romuald 2012 Barcelona

(Polyethylene, Non destructive technique, Ultrasonic Phased Array, Slow Crack initiation time) Since a few years it has been proved that - among the available concepts - the Ultrasonic Phased-Array technique (PA UT) was one of the most promising candidate for Non Destructive and Non Intrusive analysis of PE and...

Increasing energy efficiency of pipe extrusion processes through advanced polymer design

Author(s) : Ralph Handstanger, Rainer Kloth 2012 Barcelona

Most process improvement efforts in the pipe extrusion industry were traditionally aimed at increasing the throughput and/or enhancing the product quality. In recent years an additional aspect has been steadily gaining relevance: Energy efficiency. This has been driven by rising energy costs as well as by increased...

Industrial Application of PE pipes and Production Quality Control

Author(s) : Wang Zhiwei 2012 Barcelona

In recent years, considerable progress has been made in the quality of PE pipe materials and products. PE pipes have been widely used in the water and gas distribution market sectors. Also thanks to the excellent performance and chemical resistance of these high quality PE pipes they have been used in other...

Influence of Molecular weight on the properties of molecularly oriented PVC

Author(s) : Fumire Joel 2012 Barcelona

Bioriented pipes or plates show strongly improved mechanical properties compared with standard u-PVC. It is known that biorientation process is less efficient on PVC composition with lower molecular weight. The target of this study is to quantify the relationship between the molecular weight (Kw) of the composition...

Innovative approachs to assuring quality pipe compounds

Author(s) : White Jee 2012 Barcelona

As significant improvements are made to thermoplastic materials from the first generation of monomodal pipe compounds to the current generation of high melt strength, bimodal pipe compounds, signihnt innovations have occurred to assure quality pipe compounds are produced and used in this industry. One of...
