LONG-TERM PERFORMANCE AND LIFETIME PREDICTION OF GEOSYNTHETICS

Y.G. Hsuan1 , H. F. Schroeder2 , K. Rowe3 , W. Müller4 , J. Greenwood5 , D. Cazzuffi6 , R.M. Koerner7 To properly understand and assess the long-term behaviour of geosynthetic materials it is necessary to investigate the various types of possible degradation mechanims. This includes both chemical and mechanical behaviour, and sometimes even their […]

Perbandingan pipa pembuangan bawah tanah HDPE dengan pipa konkrit

1.Diameter pipa antara DN600-DN1600, rasio harga satuan komprehensif dengan diameter yang sama antara pipa HDPE dengan pipa konkrit/semen adalah 1：1.3. 2.Kapasitas aliran HDPE 1.3 kali dari pipa konkrit/semen. Misalnya jika menggunakan pipa konkrit/semen diameter DN800, maka pipa HDPE hanya perlu menggunakan diameter DN700(800/1.3). 3.Penyambungan HDPE yang sederhana dan cepat, meningkatkan kemajuan konstruksi. Dalam kondisi normal, […]

Investigation of The Failure Behavior of Polyethylene Electrofusion Sockets

Isabelle J. Berger, Andreas Frank, Gerald Pinter, David Nitsche, Dirk Petry Papers # 2018 Las-Vegas Electrofusion (EF) sockets constitute a well-established and practically proven technology for the joining of polyethylene (PE) pressure pipes. As for the pipes, the potential lifetime of such welding connections is beside other properties also depending on the resistance against slow […]

Less is more: polypropylene materials for sewerage & drainage pipes with reduced energy and carbon footprints

Papers # 2016 Berlin The environmental impact in terms of global warming potentials (GWP) and nonrenewable energy demand (NRED) of sewerage & drainage pipes based on PP-MD, PP-HM, PP-B, and concrete has been assessed using life cycle analysis methodology. It can be concluded that PP-MD and PP-HM materials are able to significantly lower both GWP […]

Chemical and Temperature Resistance of Polyethylene Pipes for Industrial Applications

Dr. Amaia Bastero, David López Piquer Papers # 2014 Chicago 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 […]

Limits On The Slow Crack Growth Resistance Evaluation For The PE100 And PE100RC Polyethylene Resins

Carlos Domínguez, Nuria Robledo, Rafael A. García-Muñoz Papers # 2016 Berlin With the last advances and improvements in the polyethylene resins used for pipe application, new methods for evaluating long-term mechanical properties need to be introduced. Standard PENT and FNCT tests needs more than one year for characterizing the new PE100RC grades with the consequent […]

Effect Of Eccentricity On The Measurement Of Hydrostatic Pressure Resistance Of Plastic Pipes

Suleyman Deveci, Birkan Eryigit, Senthil K. Kaliappan Papers # 2018 Las-Vegas The effect of eccentricity on the failure time of pipes under hydrostatic pressure test has a significant magnitude that it can easily mislead the evaluation of pipes according to requirement of ISO 4427-2. Therefore, authors propose a maximum relative eccentricity limit of 0.015, even […]
