Reinforced Concrete Pressure Pipe, Noncylinder Type

Published by: 2017-01-01 / 2017-01-01 / 40 pages
This standard covers the manufacture of circumferentially reinforced concrete pressure pipe, without a steel cylinder and not prestressed, in sizes from 12 to 144 in. (300 to 3,660 mm) inclusive and for working pressures not exceeding 55 psi (380 kPa) and for working plus surge pressures not exceeding a total pressure of 65 psi (450 kPa). This type of pipe is designed for the internal pressure, external loads, and bedding conditions designated by the purchaser. Pipe of diameters larger than 144 in. (3,660 mm) have been manufactured based on the concepts of this standard. This standard does not include requirements for design, handling, delivery, laying, field testing, or disinfection of pipe. The pipe shall have the following principal features: a reinforcing cage or cages of steel rods, bars, wire, or fabric; a wall of concrete covering the reinforcing cage or cages inside and out; and a joint with a preformed rubber gasket or gaskets of rubber of circular cross section, so designed that the joint will be watertight under all conditions of service. The purpose of this standard is to provide purchasers, manufacturers, and constructors with the minimum requirements for reinforced concrete pressure pipe, noncylinder type, including fabrication and testing requirements.
