2. Sewer pipe A pipe material is used to transport of water A pipe used to carry waste matter such as faeces or dirty water from homes and factories

3. Primary Function of Sewer Pipe The primary function of sewer pipes is to carry the sewage or wastewater from homes or commercial buildings to the drainage system to be treated or removed The sewage pipes can be damaged or decayed with time and require repairs or replacement

4. Types of Sewage Pipes Most common Sewage pipes depending upon particular application are Clay: less expensive Concrete Plastic Cast iron or steel pipes: Cast iron or Steel pipes are used under unusual loading conditions or under pressure

5. Clay Sewer Pipe Clay pipe made of clay or shale which have been grounded,wet,molded,dried and burned in kiln Near end of burning Sodium chloride is added to kiln and vaporize to form hard waterproof glaze by reacting with pipe surface Burning itself produce fusion and clay become hard and dense

6. Clay pipe manufactured with integral bell and spigot ends fitted with polymeric rings spotted at end also fitted fiber glass polyester sockets Manufactured to standard specification of ASTM3 in diameter 100 to 1070 mm

7. Strength and loading of Vitrified clay pipe Static load produced on buried pipe may be calculated using an equation of the form W=CwB2 W= Load of pipe per unit length w= weight of fill material B= width of trench

8. Benefits of Clay Sewer Pipe Reduce the risk of damage Clay pipes are inherently strong, so when it comes to laying them, there is a reduced risk of breakage or damage Reduce the risk of leaks More environmentally friendly than alternatives Clay pipes are economical

9. Plain Concrete Sewer Pipe May be used for small storm drains and for sanitary sewer in locations where grades temperature and sewage characteristics prevent corrosion Should not used for sanitary sewage in southern united states where high temperature and grades are common Manufactured to specification of ASTM

10. Reinforced Concrete Sewer pipe Precast pipe in diameter larger than 610mm is reinforced Also obtained in smaller size Size from 305 to 760mm and tongue and groove above the size

11. Asbestos Cement pipe Also known as AC pipe or  transite pipe, it is a tubular liquid transport vessel made up of cement and asbestos fibers. were first used in North America in the 1930s for potable water distribution. They were also utilized to transport gases, fumes, and  wastewater .

12. Benefits Higher Tensile Strength Better Flow Long Lifespan  Corrosion-Resistant Resistant To Deterioration Low Cost Easier Installation Disadvantages Of Asbestos Cement Pipe Use Public Health Impacts Lungs disease Pleural Disease Cancers Benign Intestinal Polyps

13. Plastic Truss Pipe Consist of extruded shell with integral diagonal stiffeners between inner and outer membrane Space between inner and outer membrane is filled with lightweight concrete which increase stiffness Section joined with chemical welding of ABS material

14. Other Sewer materials Bituminized Fiber Pipe manufactured in small size and primarily used in houses Solid wall plastic pipe size is 100 to 305mm pipe is made of polyvinyl chloride may be used alone in vacuumed and pressurized collection system Cast iron or steel pipes: Cast iron or Steel pipes are used under unusual loading conditions or under pressure Corrugated metal pipe used for storm sewe primarily used in roadway drainage

15. Corrosion of Sewers Under acidic or turbulent conditions, hydrogen sulfide is released from wastewater in the form of gas Thiobacillus bacteria in the system oxidize the gas to form sulfuric acid, which corrodes sewer pipes and weakens concrete structures, shortening the life of your wastewater treatment system
