Rigid drainage pipe

About 2 million hectares are under irrigation with low-diameter pipe made of LDPE/LLDPE in Europe. Higher diameter (>32 mm) tubes are usually made in HDPE or PVC. Western Europe used 100,000 tonnes of rigid PVC pipe for drainage and 65,000 tonnes/year of flexible PVC hose piping [45]. Apart from these materials, corrugated PP pipes, fittings, and accessories are also used worldwide. [Pg.202]

Suppose that the problem involves a length of 2-in.-diameter. Schedule 80 rigid PVC pipe holding water under a pressure of 50 psi at room temperature. The maximum allowable sag or deflection between supports is 0.25 in., which is a realistic value actually used to avoid drainage problems. It is also required that the pipe sag by not more than this amount after 10,000 hours of service. There are no wind loads and the material has an initial elastic modulus of 450,000 psi. It can now be shown that the 2-in.-diameter PVC pipe filled with water has a weight of 0.194 Ib./ft. [Pg.185]
