Continuously wound pipes for Indian irrigation project

these pipes. GRP are corrosion resistant and have an extraordinary life span. The continuous pipe manufacturing process allows the supply of long-length pipes as well as short cut pieces. This reduces the number of couplings needed and speeds up installation. The supply of tailor made pipe lengths also allows great flexibility in pipe laying. The lightweight pipes need no heavy installation equipment and their smooth inner surface guarantees low operation and maintenance costs. Pipe supply has already started and according to the contractor, installation is proceeding without any problems.

IN 1985, the Narmada Valley Development Authority, a multidisciplinary organisation of the Indian State Government, was given jurisdiction over the major water resources development projects in the Narmada region. With a length of more than 1,300km, the Narmada River passes through many Indian districts and is well known as the ‘Life Line’ of Madhya Pradesh. To support and develop regional agricultural development in Madhya Pradesh, the Indian government decided to utilise 18.25 MAF (million acre-feet) of water from the Narmada River to realise 29 major, 135 medium-sized and over 3,000 minor irrigation projects in this region. The Punasa Lift Irrigation Scheme is part of this development plan. In a first phase, to be completed in 2010, an irrigation network will be established to irrigate 3,500 hectares of land around the villages of Punasa and Mundi. The network plan, developed by the Narmada Valley Development Authority, includes existing open trench water channels as well as new irrigation lines. To avoid evaporation and to prevent erosion and water pollution through sewerage and pesticides, it was decided to install a closed pipeline system. The main requirements for the pipe system defined in the tender were easy installation and good corrosion resistance, as well as low operational and maintenance costs. In the end, Amiantit India, a supplier of Flowtite GRP pipes was awarded the contract to supply 21,000m of glass fibre reinforced plastic pipes (GRP) in diameters DN 600mm and DN 900mm with a pressure of PN 6 and a stiffness of 124 Kpa. The main reasons for this decision were the manufacturing method and the excellent product properties of
