“OM” HDPE pipes are suitable for underground & overgrown installations and are available in 20mm to 110mm sizes. “OM” HDPE pipes are also available in coils of 50, 100, 150, & up to 300 Mt. in length.
The pipes to be used in the system are made up from 100% vergin High Density PolyEthylene Granuals. It also compare or passes the IS standard mark as per IS 4984-95. This pipe is light in weight, flexible & highly durable.
This pipes are classified by pressure rating (working pressure) at 27’C in IS 4984-95
Class of Pipe | Working Pressure |
---|---|
Class I | 0.25 MPA (2.5 Kgf/cm2) |
Class II | 0.4 MPA (4 Kgf/cm2) |
Class III | 0.6 MPA (6 Kgf/cm2) |
Class IV | 1.0 MPA (10 Kgf/cm2) |
