Pipe Class Calculators & Engineering Software

The CPPAA PIPECLASS program designs and selects concrete pipe strength requirements in accordance with AS/NZS 3725:2007 “Design for Installation of Buried Concrete Pipe”.

Since the original version was first developed over 20 years ago, more than 25,000 users have registered to use the application.

PIPECLASS3, the latest release, is a result of the CPPAA listening to the community of users to develop an even more user-friendly, cloud-based application with additional design features to meet the requirements of specifiers, designers and installers.
