Technical Examples

For use in drawing samples of e.g water from a well. The sampling pipe is formed as an extrusion in polyethylene. The profile includes three equi-spaced channels. The profile, being triangulated, is rigid and resistant to buckling, which allows the sampling pipe to be coiled for transport to the site. Sample-tubes, pumps, etc, can be inserted into the channels. The channels can be plugged for isolation of sampling ports at different depths.
