Irrigation Options: The Buzz about HDPE Pipe - Golf …

Kirchdorfer introduced HDPE pipe to golf course irrigation systems in the late 1970s using HDPE on the tough appliions such as stream crossings, exposed pipe, intake pipe and poor soil conditions. During this early period of HDPE pipe in golf irrigation, from the late 1980s until the mid-1990s, the selection of fittings for the pipe was limited.

Are thrust blocks required with HDPE pipelines? | …

No. HDPE pipe and fittings joined by heat fusion are self-restrained and do not require thrust blocks. It is only at the transition to unrestrained bell and gasketed pipe that provision must be made to limit the transmission of axial forces to the other piping system.

Hydraulic Thrust & Anchoring Pipes | Saint-Gobain …

Hydraulic thrust occurs at changes in direction, reductions in diameter (bends, tees, tapers) and at the ends of pipelines carrying water under pressure. Greater freedom in designing networks Phasing out concrete anchor blocks Anchoring technologies are increasingly taking the place of concrete anchor blocks, which have many drawbacks including their weight and size.
