AWWA C-302 Non-Cylinder Reinforced Concrete Pressure Pipe is used for low head transmission lines in which the
maximum operating pressure will not exceed 380 kPa (55psi). Non-cylinder concrete pressure pipe is recommended for:

• water intakes
  
• gravity sewers (sanitary or storm)
  
• outfall sewers
  
• low pressure sewage forcemains
  
• siphons
  
• treatment plant piping
  

This superior pipe is best suited where the operating conditions require zero infiltration and exfiltration, vacuum conditions, and/or, where poor ground conditions exist.

"Standard pipe" refers to straight sections of C-302 which are manufactured in nominal lengths, typically 7.315m (24ft), 6.096m (20ft) and 4.877m (16ft). This type of concrete pipe does not require a steel cylinder, but has one or more reinforcing cages. It incorporates welded steel bell and spigot joint rings encased in the concrete wall of the pipe.

The accurately sized high grade steel joint rings with volumetrically sized rubber gasket
is designed to ensure water tightness, ease of installation, flexibility with ground movement and long service life. The joint rings have a zinc-metallized protective coating which, with the grouting of the completed joint in the field, provides a very high resistance to corrosion.

Hyprescon manufactures C-302 from 750mm (30in) to 3660mm (144in) diameters at the Uxbridge and Stouffville facilities.
