HDPE PIPES H.D.P.E. pipes conforms to IS-4984, H.D.P.E. pipes are best preferred for potable water supply, irrigation schemes, chemicals and edibles transportation, effluent collection and disposal system, submarine and underwater pipe lines, hydro transport system, gas/compressed air system etc.. H.D.P.E. pipes have been preferred over other available a vailable resources due to varied salient features 1•
High corrosion resistance, resulting into a longer life.
2• High impact strength. 3• Extremely light weight and hence easy to handle. 4• High flexibility. 5• High abrasion resistance. 6• Excellent water hammer characteristics, chara cteristics, helps sustaining surges. 7• Excellent flow characteristics leading to significant energy saving. 8• No exfiltration and infiltration, helps maintaining the quality of fluid being conveyed. 9• No trenches needed, resulting into easy and economical installation. 10• High UV resistance. 11• High resistance to scaling and biological build up. 12• High chemical resistance, absolutely inert to any pH value. 13• Virtually maintenance free.
Applications Industrial 1• In petrochemical, paper, dye, paint, cement and other chemical industries for disposal of chemical effluent and waste. 2• Oil and milk transportation in industries and dairies 3• Discharge of radioactive waste 4• Acid and Slurries transportation 5• Compressed gas supply at mines and construction sites 6• External & internal drainage and sewage 7• Salt water handling Agricultural 1• Water supply for irrigation in fields 2• Drip irrigation scheme 3• Sprinkler irrigation 4• Insecticide spraying 5• Drawing water from pump set for distribution 6• Most suitable for submersible pumps and jet pumps.
Domestic 1• For potable water supply in rural and urban areas, Other 1• Telecommunication cable ducting 2• Bio-gas, coal gas & natural gas distribution lines for domestic and industrial use. 3• Air conditioner ducting 4• Submarine delivery system
Salient Features Strong and Durable H.D.P.E. Pipes are strong, resilient and impact resistant. Light Weight Are easy in handling, transportation & installation, even on difficult terrain Length as Required Are available in straight as well as coil lengths, so less joints & couplers needed. Better Flow Characteristic There is no deposit deposit formation, formation, so diameter diameter of pipe remains the same same and and hence hence better better flow. Hygienic & Odorless There is no contamination contamination as the pipes are resist resistant ant to 1• Scale formation 2• Chemical formation 3• Biological formation Energy Saving Have smooth internal surface which implies low frictional loss. Hence the power consumption is on lower side. Leak Proof Are leak proof due to close dimensional tolerance & precision designing and joining. Chemical Resistance Are totally inert to all the chemicals. Economical Are reasonably priced and long lasting. These pipes have better flow characteristics so a small diameter pipe can be used. Long Lasting Are in fact 10 times longer lasting than GI or Rubber pipe. These pipes are free from rusting, weathering & abrasion therefore are an investment for a life time. Maintenance Free Have no breakage and are unaffected by environmental stress.
