HDPE Pipes & Coils

MATERIALS : It is made of either of three grades of High Density Poly Ethylene polymers. i.e PE-63, PE-80 or PE-100

PRODUCT RANGE : These HDPE pipes are available in sizes 20 mm to 500 mm in pressure rating of PN-2.5, PN-4.0, PN-6.0, PN-8.0, PN-10.0 , PN-12.5 & PN-16.0 in all three grades PE-63, PE-80 and PE-100.

APPLICATIONS : Effluent and Waste Water Disposal: Effluents of varied chemical compositions can be effectively disposed of using Kadambari HDPE pipes & coils, with the aid of the latest know-how on piping engineering, pipelines for waste collection and disposal in chemical industry. Longevity of Kadambari pipes under such application would rate the best amongst the conventional pipe even under critical service conditions.

Domestic Gas Distributions : Earlier, engineers always carried a psychological fear in using HDPE pipes rather plastic pipes for conveyance of inflammably gases. However experiments and extensive trials proved these fears totally wrong and have established excellence of performance of HDPE pipes for conveyance of all type of combustible gases. Experiments have also proved that the permeable losses are insignificant in regard to safety and environmental impact

Submarine Pipelines : One of the most important applications where all salient features of Kadambari pipes prominently figure out is for under water pipelines. Kadambari pipes have been successfully laid for under water river crossing, creek crossing, marine out-falls and for brine intake lines in the open sea. Hazardous chemical effluents and radio active wastes are being harmlessly disposed into deep sea through Kadambari pipes with substantial cost savings. Schemes which would have been dropped due to economical un-viability have been made feasible with Kadambari pipes.

PROPERTIES

  • Economical than traditional pipe material.
  • Resistance to chemicals- Exceptional resistance to all external and internal corrosion.
  • Resistant to electrolytic corrosion.
  • Will not rust or rot.
  • Very good thermal insulation due to low thermal conductivity.
  • Perfect stability of material obviates the risk of ageing.
  • Total neutrality to products conveyed.
  • Low maintenance cost.
  • Easy to install.
  • Longer life than G.I, M.S cement and other pipes.
  • Flame resistance classifying the material as self extinguishing according to test standard employed.
  • Welded joints speedup installation- Trench widths reduced which leads to saving in the cost of excavation and back filling.
  • Light weight - One sixth of the weight of steel. Low specific gravity giving an outstanding light weight product for easy transportation, handling, fitting etc.
  • Smooth bore provided less head loss. Flow resistance is approximately 30 % less than that of conventional pipes, permitting the use of a smaller bore pipe for a given rate of flow.
