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 […]

HDPE-Geopipes, Soil-Structure Interaction

Zanzinger LGA, Geotechnical Institute, Nuremberg, Germany Gartung LGA, Geotechnical Institute, Nuremberg, Germany Perforated geopipes are part of the leachate collection system at the base of solid waste landfills. Their structural performance depends on the embedment which is formed by a compacted clay layer, a geomembrane and a sand-bentonite cushion below and coarse gravel above the […]

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, […]

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 […]

Expanding The Application Range Of High Density Polyethylene For Use As An Inner-Liner Material In Reinforced Thermoplastic Pipe And Steel Pipe

Johannes de Bruin, Dr. Bert Dalmolen, Albo van Hateren Papers # 2016 Berlin Normal High Density Polyethylene (HDPE) is commonly used as the fluid contacting element, or the “inner-liner”, in Reinforced Thermoplastic Pipes (RTP) and steel pipes up to 65 ºC. Through a modification of the HDPE polymer matrix, by adding nanoparticles, the E-modulus can be increased. […]

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 […]

New Process For The Hot Forming Of The Integrated Socket On Underground Drainage Pipes Made Of High Modulus Polypropylene With A Compact Or Multilayer Wall Structure

Giorgio Tabanelli Papers # 2018 Las-Vegas In underground plastic drainage pipes the integrated socket joint technology is now used widely in PVC pipes with a compact or multilayer wall. On the other hand, in PP and HDPE pipes this form of connection, despite its well-known advantages, is still not widely used. The reason for this is basically […]
