DR-4 - Most versatile mapping system
The DR-4 has proven to be the most versatile and unique multi-purpose pipeline mapping system. With a proven track record on every continent and in most pipeline segments, this multi-diameter system has easy handling features and provides the most accurate positional data location.
A unique system of exchangeable centralizing wheel-sets gives the DR-4 an operational range of ID90mm (3.5") to ID1500 (60"). Whether the pipeline is made of steel, concrete, PE or PVC, this mapping system will improve any horizontal directional drilling (HDD) implementation procedure.
A selection of invert wheel-sets are also available to map pipes with tight access and/or lateral feeder lines.
