Dura-Guard™ Comparison With RCC, GI And PVC Ducts

Property	Dura-Guard™ Duct	RCC Pipe	GI Pipe	PVC Pipe
ChemicalResistance	Good resistance to acids & alkalis	No resistance to most alkalis& acids	Low resistanceto acids and alkalis	Moderate resistance to mostalkalis and acids
Soil Settlement	Being flexible, adjusts itself to soil settlement. Does not crack	Does not adjust itself to soil settlementand cracks	Does not adjust itself to soil settlement andgets stressed	Does not adjust itself to soil settlement and cracks
Transportation & Handling	Easy handling due to light weight. Cost of transportation is low	Very heavy & brittle. Difficult to handle, chances of breakages during handling and transportation.Cost of transportation is high	Very heavy. Cost oftransportation is high	Easy handling. However losses occur due to breakages caused due to its limited flexibility
Flexibility	Flexible, can be bent to a radius as low as10 x O.D. of the duct	Rigid, cannot be bent	Rigid, cannot be bent	Rigid, cannot be bent
No. of Joints	Less number of joints. Can be supplied in coilform in length up to 30m	More joints. Supplylength 1.5 to 2.0m	More joints. Standardsupply length 6.0m	More joints. Standardsupply length 6.0m
Laying of Additional Ducts/ Replacement of Ducts & Cables	Possible due to alignedjoints, continuous length and smooth bends	Not possible. High chances of breakages/damages.Re-digging is necessary	Not possible due to sharp bends. Re-digging is necessary	Not possible as joints are of permanent nature. Re-digging is necessary
