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 […]
