Stress Concentrations Around Circular Holes in Perforated Drainage Pipes

Authors: R.W.I. Brachman, , and R.P. Krushelnitzky, Stress concentrations around circular holes in perforated buried pipes obtained from three-dimensional elastic finite element analysis are presented. The maximum stresses around the perforation were found to depend on the thickness and diameter of the pipe, the diameter of the perforation, the circumferential location of the perforation, and the axial and circumferential […]

Earth Pressure Measurements On Buried HDPE Pipe

Authors:  M.L. TALESNICK*, H.-W. XIA†, and I.D. MOORE† An understanding of the stress distributions that act on buried pipes plays a key role in the development and use of design methods for these structures. The radial stresses that develop on buried flexible pipes have been investigated by a number of researchers through experimental, analytical and numerical methods. […]

Performance Of Buried HDPE Pipes- Part 1 : Peaking Deflection During Initial Backfilling Process

Zhou1 Y. J. Du2 F. Wang3 M. D. Liu4 PhD Candidate Professor and Director Associate Professor Senior Lecturer Peaking deflection caused by compacting the sidefill, referred to as the maximum change of the pipe diameter divided by the undeformed diameter, is an important parameter in the design and safety check of buried pipelines. However, quantitative equations on the deflection useful for engineering […]

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, […]

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 […]

Study On Parameters Affecting Durability Of Polyethylene Pipes For Hot Water Application

Hirofumi Kyutoku, Kazuhisa Igawa, Hidekazu Honma, Sakiko Fukunishi, Hiroyuki Nishimura Papers # 2018 Las-Vegas There are mainly two grades of polyethylene pipes for hot water supply and heating. The excellent molecular structure polyethylene resins having resistance to stress crack growth are used because hot water is flowed for a long time in both polyethylene pipes. […]
