Up to 70 percent less expensive than iron pipe, PVC pipe is an easy winner when it comes to saving water utilities money on capital expenditures (See: "Pleasanton's Underground Infrastructure: Sustainability, Cost-Efficiency Through Better Materials Procurement Practices," U.S. Mayor). Equally important, PVC is also the best performing pipe available according to a landmark study by Utah State University’s (USU) Buried Structures Laboratory. Better performing pipes help reduce operations and maintenance costs, which are spiraling out of control at 6 percent above the annual rate of inflation mainly because of the use of corrosion-prone piping materials.
Study: PVC Pipe Has Lowest Failure Rate, Corrosion a Problem for 75% of U.S. Water Utilities
According to USU’s “Water Main Break Rates in the USA and Canada: A Comprehensive Study,” PVC pipe has the lowest overall failure rate when compared to cast iron, ductile iron, concrete, steel and asbestos cement pipes. Water main breaks are calculated for all pipe materials used in the transport of water to create a measurement to judge pipe performance and durability. The data for the comprehensive report was collected from 188 utilities, representing approximately 10% of the nation’s installed water main pipe network...

回复删除Uni-Bell PVC Pipe Association, PVC gasketed pipe has a factory-installed rubber ring joint. This locked-in-place design prevents fishmouthing or accidental dislocation of the sealing gasket when pipe spigots are inserted in the bell joint. Do not attempt to remove the gasket from the gasket groove.
