Fee for non-members $30+HST.
Overview:
Traditional air valves designs from some sixty years ago are outdated. Premature closing, inadequate air relief capacity or surge damage are the main factors that can make these installations ineffective. New designs are available to you incorporating modern air relief set ups inside corrosive resistant, anti-surge bodies.
Get out of the chambers! Eliminate costly air valve manhole chamber installations, transitioning pipeline materials, water infiltration through manhole apertures threatening potable water quality, and confined space safety requirements. Air valve cannisters to be installed directly over or off the pipeline are the answer to managing air inside pipelines. Direct bury air valves are designed to be serviced from above ground.
At the completion of this one-hour OJT session, participants will be able to demonstrate the following:
-
-
-
-
-
- How air infiltration affects pipeline performance and where to expect the air to accumulate.
- The two basic and unrelated air valve functions.
- Air valve chamber design requirements when upgrading existing installations
- Direct bury air valve design alternatives to avoid problems in the future.
