Aluminum Pipe Markers
Berntsen orbital forged aluminum survey caps for iron pipe with insulators attach to pipe with a few sharp hammer blows with a urethane hammer. The virtually straight walled socked and plastic insulator wedge create a strong compression fit between the pipe and the cap. The popular PC8200 two-inch (50.8 mm) cap diameter is available to fit one-inch (25.4 mm) ID standard pipe..
Our aluminum material is versatile and resistant to most environment conditions, however, if the survey markers are intended to be used in high traffic or caustic environments, such as roadways or salty conditions, we highly recommend using bronze survey markers to improve the lifetime of the markers.
