THE IMPORTANCE OF CHEMICAL STABILIZATION IN RECYCLED MATERIAL FOR CORRUGATED AND CONDUIT POLYOLEFIN PIPES

摘要

Much attention has been given to stabilization packages for polyolefin pressure pipes over the past couple decades,however corrugated and conduit pipes have generally been ignored with respect to more robust stabilization packages.Certain groups such as the Florida Department of Transportation have set rules establishing oxidative resistance in HDPE corrugated pipes,but few others have followed this example.A discussion of the simplicity and importance of pipe resin stabilization as well as examples from stabilized pipes will be covered.
