The global crisis has brought new challenges to the water industry. The water infrastructure sector is forcing to lower product and installation cost, boosting installers and pipe manufacturers to offer alternative solutions more efficient.
Currently pipe materials are used for water transport include mainly plastics (PVC, HDPE) and metals (Ductile Iron, Cast Iron). Plastic materials are more likely to be used for small and medium water nets, with pressures ranging up to PN 16 bars, due to material brittleness and low impact resistance restrictions. Ductile iron is used for large water nets, in pressure PN 25 bars. However, other troubles arise due to corrosion and therefore, service life expectancy is compromised.
In the recent years, new technologies have emerged to manufacture PVC-O pipes that considerably improve the traditionally mechanical properties of plastic pipes. International standards rule the PVC-O pressure requirements, which enable pressure pipe applications up to PN 25 bars.
Pioneers in the line of manufacturing of plastic pipes in India, Ori-Plast launches PVC-O Pipes.
The pipes are made complying to the Standards ISO 16422 and IS 1616.
PVC-O pipes have a wide range able to cover all the needs of medium and high pressures. Ori-Plast is manufacturing PVC-O pipes in nominal diameters (DN) 90, 110, 140, 160, 200, 225, 250, 280 and 315 mm and pressures (PN) 16 and 25 bars.
Hydraulic capacity: PVC-O piping systems have between 15% and 40% more hydraulic capacity. This is because Molecular Orientation reduces the thickness of the pipe wall, giving PVC-O pipes a greater internal diameter and flow section. Besides, the internal surface is extremely smooth, reducing load loss
Unbeatable impact resistance: PVC-O CLASS 500 pipes are not easily destroyed by regular impacts. The risk of bursting during installation due to stone dropping or impact is minimal. The layered structure achieved with the molecular orientation process keeps from crack propagation and scratches.
No crack propagation: The layered structure achieved with the Molecular Orientation process is the main feature which prevents from crack propagation along the pipe wall thickness. During the installation, scratches caused by stones on the site might be produced. When cracks appear, they progress through the amorphous wall structure. In PVC-O CLASS 500 pipes, these cracks remain on the first layers, not affecting the pipe’s properties at all.
Flexibility: Thanks to the excellent elasticity, PVC-O pipes can withstand deformations of their internal diameter without the appearance of fissures. If the pipes are flattened, or if they are involved in any kind of mechanical accident, they immediately go back to their original shape. Moreover, there is no risk of breakage from land subsidence or sharp impacts, such as from stones or machinery.
Fully watertight: PVC-O pipes ensures a perfect watertight fit. To this end, the pipes have a seal composed of a polypropylene ring and a synthetic rubber lip that makes them be an integral part of the tube, preventing them to move from their emplacement or moving around generally while being installed.
