Estimation of Service Life of Concrete Pipes in Sewer Networks
The expense of repair and maintenance of private and public sewage systems in Germany runs to about 100 billion US $. This primarily affects concrete pipes and brickwork sewers. Approximately 40 per cent of the damage can be attributed to corrosion by biogenous sulfuric acid attack as a result of long flow periods and insufficient ventilation of waste water. The report deals with investigations...
متن کاملcomparative evaluation of poly urethane and poly vinyl chloride in lining concrete sewer pipes for preventing biological corrosion
corrosion makes huge economic and ecologic damage all over the world. biologic corrosion of sewer pipes is considered as a serious limitation in economic perspectives. to prevent biologic corrosive damage, lining techniques can be applied by materials and aggregate resistant to attack bacterially in sewer pipes. the role of bacteria is that they convert sulfur compounds into sulfuric acid which...
متن کاملFuzzy Expert System to Assess Corrosion of Cast/Ductile Iron Pipes from Backfill Properties
Several factors may contribute to the structural failure of cast and ductile iron water mains, the most important of which is considered to be corrosion. The ANSI/AWWA C105/A21.5–99 10-point scoring (10-P) method is commonly used to predict corrosivity potential of a given soil sample using certain soil properties. The 10-P and other scoring methods use binary logic to classify the soil either ...
