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...

ACCEPTANCE CRITERIA FOR NON-DESTRUCTIVE TESTING OF PE ELECTROFUSION JOINTS

Author(s) : Peter Postma 2016 Berlin

On request of the Dutch DSO’s and in cooperation with all important Dutch stakeholders (producers, suppliers, contractors and the regulator), Kiwa Technology investigated the relevancy of defects found with Phased Array Ultrasonic Testing (PAUT) and if it was possible to determine acceptance criteria. The project...

ADVANCED APPLICATIONS FOR HDPE PIPES WITH NEW PE-RT MATERIAL

Author(s) : Wes Long, Carl F. Baker 2016 Berlin

Canfor’s Prince George Pulp & Paper Mill in Prince George, BC, Canada operates a bleach plant effluent system for the production of Bleached Kraft Pulp. The original underground fiberglass reinforced pipe (FRP) presents an elevated risk to both environment and production targets. Over the past five years there...

ADVANCED CHEMISTRY IN PE POLYMERISATION ALLOW NEW POSSIBILITIES FOR PE-RT TYPE I RESIN

Author(s) : Alex Stolarz, Jian Wang 2016 Berlin

THE PE-RT TECHNOLOGY HAS EVOLVED SINCE IT HAS FIRST BEEN INVENTED 1982. AN ESTABLISHED TECHNOLOGY FOR HOT AND COLD SANITARY PIPES HAS POSITIONED ITSELF WELL WITHIN OTHER MATERIALS DUE TO THE EASY PROCESSING, HANDLING AND COST EFFICIENT PRODUCTION OF PIPES. 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...
