|Publication Date:||19 June 2016|
This standard describes the manufacture of reinforced concrete cylinder pipe in sizes 30 in. to 144 in. (760 mm to 3,660 mm), inclusive. Larger sizes have been manufactured based on the concepts of this standard. This type of pipe is designed for the internal pressure, external loads, and bedding conditions designated by the purchaser. This standard does not include requirements for design, handling, delivery, laying, field testing, or disinfection of pipe. Refer to AWWA Manual M9, Concrete Pressure Pipe, for information on these topics.
Essential requirements. The pipe shall have the following principal features: a welded steel cylinder with steel joint rings welded to its ends; a reinforcing cage or cages of steel bars, wire, or welded wire reinforcement; a wall of concrete encasing the steel cylinder and reinforcing cage or cages inside and outside of the steel cylinder; and a joint with a preformed gasket of rubber, designed so that the joint will be watertight under all conditions of service.
The purpose of this standard is to provide the minimum requirements for reinforced concrete pressure pipe, steel-cylinder type, including fabrication and testing requirements.
