This standard defines the methods to be used in the structural design of buried prestressed concrete cylinder pipe (PCCP) under internal pressure. These methods are provided for the design of pipe subjected to the effects of working, transient, and field-test load and internal pressure combinations.The design procedures of this standard are applicable to lined-cylinder pipe (LCP) having inside diameters of 16 in. through 60 in. (410 mm through 1,520 mm) and to embedded-cylinder pipe (ECP) having inside diameters of 24 in. (610 mm) and larger.
PCCP is used principally in the transmission and distribution of water in municipal, industrial, and irrigation systems. It is also used in plant piping systems, seawater cooling systems, sewer force mains, and gravity sewers. Other applications include inverted siphons, liners for pressure tunnels, and culverts with high earth covers.
The major revisions made to the standard in this edition include the following:
1. The unit weights for concrete and mortar have been made consistent throughout the standard.
2. An alternate criterion has been added for surcharge load computed in accordance with recognized and documented analytical procedures based on soil?pipe interaction.
3. The design yield strength of the steel cylinder in tension has been changed.
4. Numerous editorial improvements and reference updates have been made throughout.
