1.1 This specification covers nonreinforced concrete pipe with rubber gasket joints to be used for the conveyance of irrigation water with working pressures, including hydraulic transients, as shown in Table 1.

1.2 A complete metric companion to Specification C 505 has been developed—C 505M; therefore, no SI equivalents are presented in this specification.

Note 1—This specification is for manufacturing and purchase only and does not include requirements for bedding, backfill, installation, or field repairs. The owner is cautioned that he must correlate field conditions with the characteristics of the pipe specified and provide inspection during installation.


This specification covers nonreinforced concrete pipes with rubber gasket joints for use in irrigation water conveyance with working pressure, including hydraulic transients. The concrete material shall consist of cement, fly ash, ground granulated blast furnace slag, and some allowable combinations of cementitious materials. The gasket should be extruded or molded and cured from natural or synthetic rubber, or a mixture of the two. The gasket material should also conform to the specified values of the ultimate elongation at break, ultimate elongation at break after aging, hardness, compression strength, water absorption, and ozone resistance. Pipes should be manufactured with male- and female-type joints designed so that the flexibility and water tightness of the joint will only be dependent on the rubber gasket. The joint should be designed to allow pipe deflection and to withstand the forces caused by gasket compression without cracking or fracturing. A lubricant may be used if required to facilitate assembly of particular joint designs.
