“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.

Versatile Application :-

The major and end use of “OM” HDPE pipes are

  • Telephone / Cable ducting
  • Drip & Sprinkler Irrigation
  • Potable water supply under water piping.
  • Fuel gas distribution.
  • Irrigation (Flow, lift, gravity flow)
  • Sewage & Sanitation piping.

Techno-Economic Advantage

“OM” HDPE pipes have various advantages over the conventional pipe system. These are

  • Outstanding resistance to conventional chemical & environments.
  • Light in weight.
  • Long length up to 500 Mt. (depending upon the size)
  • Exception durability and long life.
  • Excellent flow characteristics.
  • Absolutely light & lick proof.
  • Earthquake Resistance

Classification of Pipe

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)

Comparison of “OM” HDPE Pipes with Others

Properties HDPE Pipe Galvanized Pipe A.C. Pipe Cast iron Pipe
A) Weight Light
(Approx 10 time Light as compare to others)
Heavy Heavy Very Heavy
B) Surface Very smooth Rough Little raugh Rough
C) Length 6 Mtr. & upto 500 Mtr 5-6 Mtr. 3-4 Mtr. 3-4 Mtr.
D) Flaw Initially 50 & more flow in comparison to others & retail that standard till end. Initially flow get reduced slowly because of rust. Initially flow is 40% more Initially flow reduced by 40 to 50% after 5 to 10 year.
E) Rusting Do not get rusted Get rusted do not get rusted roped rust formation
F) Fitting arrangement Very easy, quick & leak proof Threading Is required Easy Very laborers & time consuming
G) Life Last a life line Get rusted so required to be changed after 30 years. Less chances of changing Required to to change after 20 Years.
H) Cost Very Very less Expensive Very expensive less expensive Very Costly
(I) Earth Quack Resistance YES NO NO NO
