FLOWTITE GRP piping products and accessories offer many advantages for the use in Hydropower and Penstock applications.

Due to the worldwide product availability, the Amiantit Group has established penstocks all over the world. The following case studies represent only a small extract of the available references. Only in Norway, more than 200 penstocks have been installed with FLOWTITE GRP pipes since 1975. And in many other countries around the world an increasing number of installations were already installed or they are recently in work.

Further information about additional references and case studies can be found on our website at www.amiantit.com!

Additional information about product advantages and available product range of our GRP pipes for the use in hydropower projects are available in our brochure “Flowtite GRP Pipe systems - for Hydropower and Penstock applications - “. Please request it from your local dealer.

PROJECT NAME: Hidroeléctrica Montecristo

Country/Community: Guatemala


Description: The project makes part of three small hydroelectric power plant projects installed in line and called, from top to bottom, Hydroelectric El Canada, Hydroelectric Montecristo, and Hydroelectric El Recreo. Montecristo is designed to generate 12,9 MW with a net fall of 106m and an average flow of 14 m3/s supplied form the discharge of the El Canada project.The flow delivered is transported to the water house using a low pressure line of GRP pipe with a length of 560m and diameter DN2600 mm, to a reservoir of regulation with a capacity of 16.500m3. Downstream, there is a line of high pressure, with approximately 1600m of GRP pipe in diameters of DN2500 and DN2400, and pressures from 6 to 16 bars.The project began its construction in 2005 and the GRP pipe and fittings for the project were produced and delivered by Flowtite Andercol S.A. whose factory is located in Medellin - Colombia.
