A SIMPLE DESIGN PROCEDURE FOR PVC PIPE TO ACCOUNT FOR CYCLIC PRESSURE LOADING

Author(s) : Steven Folkman, Ron Bishop 2016 Berlin

One of conditions design engineers face is selecting an appropriate pipe wall thickness (or DR) that will accommodate both maximum operating pressure and repeated surge pressure events. Methods for assessing the number of cycles to failure is quite well developed for PVC pipe. Fracture mechanics approaches can be very...

RECENT TECHNOLOGY ALLOWS EVEN MORE FLEXIBLE RESINS TO BE...

Advancing of Plastic Corrugated Pipe Systems in India in Last Two Decades

Author(s) : C.B. Dandekar 2016 Berlin

Plastic Corrugated Piping System (PCPS) was introduced in India in 2001, much later than the western world started using it for various applications. It received a mixed response from the Govt. Agencies, but was well accepted by the market, actual users and standardizing institutions. PCPS finds applications in...

ASSESSMENT OF FUSION DEGREE OF UNPLASTICIZED POLY (VINYLCHLORIDE)(PVC-U) PRODUCTS USING TORQUE RHEOMETER

Author(s) : Fu Zhimin, He Guoshan, Wang Wanjuan 2016 Berlin

Our research shows that in a torque rheometer test the greater the fusion degree of PVC-U is, the higher the minimum torque of the torque curve is, and the smaller the difference between the maximum torque and the minimum torque of the torque curve. According to the relationship, the method of evaluating the fusion...

ASSET MANAGEMENT OF POLYETHYLENE GAS NETWORKS

Author(s) : Ian Aldridge, Declan Robinson, Dave Smart, Chris Reed, Martyn, Greig, Trevor Stafford, David Christie-Lowe, Alec Erskine 2016 Berlin

For the UK polyethylene (PE) gas pipe network, the first installations now exceed 40 years in the ground, with an original design life of 50 years. It was thus timely to review the current condition and performance history of these first generation PE materials. A major 4 year project was started in 2010 to examine...

ASSURED QUALITY OF BUTT FUSION AND ELECTROFUSION WELDING OF PE100 PIPE

Author(s) : David Chrystie-Lowe 2016 Berlin

The many benefits of PE100 pipe materials include flexibility and toughness in addition to being relatively light products that are not subject to corrosion and expected to last well beyond the design lifetime [1]. It is also a distinct advantage that end-load resistant joints can be made using butt fusion (BF) and...

BENEFITS OF MULTILAYER PIPE SYSTEMS WITH AN EVALTM EVOH BARRIER LAYER

Author(s) : Mieke Vanhoof, Cynthia Teniers 2016 Berlin

Since many years EVOH (ethylene/vinyl alcohol copolymer) is applied in plastic heating systems [cross-linked polyethylene (PEX), polyethylene of raised temperature resistance (PE-RT), polypropylene (PP), polybutylene (PB)], where its excellent gas barrier properties ensure a minimization of corrosion of the metal...

BI-ORIENTED PVC EXTRUSION: STRETCHING PIPE PERFORMANCE

Author(s) : André Nijland 2016 Berlin

Bi-oriented PVC (PVC-O) pipes are increasingly installed on a worldwide basis for drinking water applications. This is due to the outstanding mechanical properties of PVC-O pipes, such as high strength and high ductility. Furthermore bi-oriented PVC pipes are light weight, flexible and have a low carbon footprint and...

BIG DATA, BIG DIFFERENCE

Author(s) : Nick Mark, Eric Bridgstock, David Carey 2016 Berlin

An insight into a unique approach to the management of electrofusion and butt fusion joint quality on polyethylene pipelines. The presentation will reference experience and learnings from a system that has already been used in the field to great effect (see Abstract) and a new approach to butt fusion (see enclosed...

CAN PE AND PVC GAS DISTRIBUTION PIPES WITHSTAND THE IMPACT OF SUSTAINABLE GASES?

Author(s) : René Hermkens, Ernst van der Stok, Johannes de Bruin, Jeroen Weller 2016 Berlin

The replacement of fossil fuels like natural gas by sustainable gases such as biogas and hydrogen can mitigate global warming. There has been some debate about the impact of sustainable gases on the materials used in the gas grid. An extensive study of the behaviour of PE, PVC, POM and rubber materials was therefore...

CHAIRMAN’S REVIEW OF THE DEVELOPMENT PROCESS FOR U.S. PIPE STANDARD AWWA/ANSI C906-15

Author(s) : John Fishburne 2016 Berlin

The United States water industry relies heavily on American Water Works Association (AWWA) Standards publications for product ratings, design parameters, and guidance on installation methodologies. In September 2015, AWWA published Standard C906-15 covering 4” – 65” polyethylene pressure pipe for waterworks...

CHALLENGES IN THE DEVELOPMENT OF THE MARKET FOR LARGE DIAMETER PE PIPES FOR MARINE INSTALLATIONS

Author(s) : Ingemar Bjorklund, Trygve Blomster, Ilija Radeljic 2016 Berlin

The S-bend installation method is the reason for the successful worldwide development of the market for marine PE pipelines over the last 50 years. Small and medium sized PE pipes can safely be installed using the S-bend installation method; however, difficulties increase as pipe sizes increase. In order to ensure a...

Close-fit Pipe Lining Without the Machines

Author(s) : Derek Muckle 2016 Berlin

It has long been the case that plastic pipes have been subject of folding operations in a factory and then supplied to site for use in pipeline renovation applications. The same cannot be said for pipes subject to diameter reduction as they have, as a principle, relied on being diameter reduced at site in a forming...

Comparative Life Cycle Assessment of a PVC-U rain gutter system versus a system made from galvanized steel

Author(s) : Carolin Spirinckx, Peter Sejersen, Zoran Davidovski, Karolien Peeters 2016 Berlin

For the European Plastic Pipes and Fittings Association (TEPPFA) it is important to have an insight into the environmental aspects during the life-span of plastic pipe systems all the way from the cradle to the grave. The result of the studies allows TEPPFA and its member companies to distinct (for the pipe systems...
