PLASTIC PIPEWORK FOR GAS IN BUILDINGS AND THE CONSEQUENCES OF FIRE

Author(s) : Hella J.M.Rijpkema, Hendrik J.Roebers, Marco C.A.Mekes 2012 Barcelona

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...

Polyethylene Pipe and Hydroelectric Development

Author(s) : Sandstrum Steve 2012 Barcelona

The term “hydroelectricity” conjures images of massive concrete dams and vast reservoirs that harness the power associated with moving water. More recently, however, technological advancements and environmental awareness have resulted in renewed interest in small-scale hydroelectric projects. These unique...

POLYETHYLENE PIPES: PE WATER PIPES AND CHLORINATED DISINFECTANTS: A PRAGMATIC APPROACH TO EVEN SAFER SOLUTIONS

Author(s) : Francis R. Costa, Christophe Salles, Anh Tuan Tran, Jeroen Oderkerk and Thomas Hjertberg 2012 Barcelona

Over the years polyethylene has gained preference as the material of choice for water distribution pipes due to its long successful track record offering comparatively lower frequency of leakage, corrosion resistance, flexibility, light weight, easy installation, etc. However, in recent years, there have been...

POLYPROPYLENE FOR STRUCTURED SEWAGE PIPES. COMPARATIVE STUDY OF MATERIALS IN USE THROUGH COMPUTER SIMULATION OF RADIAL COMPRESSION

Author(s) : Dario Sinnone, Francesca Tisi, Mario Vitali 2012 Barcelona

Polypropylene is widely used for double-wall structured pipes for sewage applications due to the superior performance it demonstrates versus traditional materials such as high density polyethylene, concrete and metals. Its outstanding balance of mechanical properties enable optimized designs and reduced weight per...

PP-MD PUSHFIT SILENT PIPING SYSTEM REINFORCED WITH NANO FILLERS

Author(s) : Alireza Sahaf Amin, Dr.Reza Bagheri 2012 Barcelona

A minerally reinforced polypropylene (PP-MD) ,Because of its high specific weight and its special molecular structure, is able to absorb airborne noise as well as structure borne noise created in soil & waste piping system. The Main mechanism of damping the sound in this piping structure is increasing the density...

Predicting slow crack growth resistance inPE resins

Author(s) : Deslauriers Paul 2012 Barcelona

(Key words: polyethylene, slow crack growth, primary structural parameter) In this paper molecular weight and SCB data obtained experimentally or digitally generated are combined into a single, primary structural parameter (PSP2) and used to rapidly screen the slow crack growth resistance of a variety of...

Production Technology Of Large Caliber Reinforced Polyethylene Pipe

Author(s) : Li Xing 2012 Barcelona

Large Caliber Steel Wire Reinforced Polyethylene pipe is composited from profiled wall HDPE with middle layer steel wire reinforcement, current diameter ranges from 400mm to 3000mm. The pipe combines the high rigidity of the steel wire ,the elasticity and good corrosion resistance of the PE resin, as well as the...

Protective Sheeting For Polyethylene Pipe

Author(s) : Tanaka Hiroaki 2012 Barcelona

Polyethylene (PE) pipes for gas supply, which have been widely used in recent years, have superiority in installability, seismic performance and corrosion resistance, while their resistivity against external force such as from strikes by excavator bucket edges is inferior to metal pipes. Under some installation...

PVC-O PIPES FOR BIG PRESSURE NETS: DN500 & DN630

Author(s) : Antonio Arena 2012 Barcelona

With the new DN500 & DN630 PVC-O pipes in PN16 and PN25 the possibilities of Plastic Pipes to compete against metal pipes in large diameters and high pressures increase dramatically. Advantages in terms of economic costs, hydraulic capacity, simplicity of installation, quality of water, absence of corrosion and...

PVC-O PIPES FOR WATER AND WASTE WATER APPLICATIONS: STANDARDISATION, QUALITY AND APPLICATIONS

Author(s) : Frans Alferink and Jos Oosterik 2012 Barcelona

PVC-O pipes were already introduced in the mid-seventies, but why did it take until the beginning of this century before this high quality pipe product really expanded successfully into the water markets? The second part of this paper will present an answer to that question. Feedback from various pipe markets...
