Hari Plaast HDPE Pipes are manufactured in sizes from 20mm to 315 mm Outside Diameter in all Classes Pressure Ratings as per IS:4984-1995 & IS-14333-1996. The pipes are available in Coil-Form or Straight Lengths depending on sizes and customer requirements. A complete range of fittings such as Pipe Ends, Bends, Tees, Elbows, Reducers, Flanges are also fall under the range of manufacture.
FEATURES AND BENEFITS
Economic Pipes and fittings are about 30% cheaper in material cost and 35% cheaper when installation cost are compared.
Light- weight Pipes are extremely light.
Highly flexible Easy installation on uneven contours/unleveled trenches.
Low friction Pipe walls are very smooth resulting in lower frictional losses. Do not permit any bacterial growth or algae.
Chemically inert Immune to corrosion due to any reasons with all chemicals from PH 0 to 14.
Weather resistant Pipes made from HDPE contain non toxic additives like carbon black which safeguards the use in open sunlight & do not pose any problem or stringency regarding their use for potable water supply.
Long life Designed to 50 years trouble free life in all kind of environ- ments.
FIELD OF APPLICATION
Water supply Certified by NEERI for potable water transport
Effluent transport Long service life in handling effluents of all kinds.
Chemical transport Can resist corrosion by chemicals from PH 0 to 14. Can safely be used in hostile environments for acids, sludge, D.M.Water.
Gas transport High creep strength PE pipes ideal as gas carriers for Natural gas, Coal gas, LPG etc.
Slurry transport High abrasion resistance together with immune ness to corrosion is an advantage for handling slurry mixture of iron water, Boiler ash water & dredge slurry disposals.
Telecom ducts For use as underground optical fiber conduits.
Irrigation For micro and sprinkler irrigation systems.
