The Smart Gamma™ Pipe Scan is a trusted solution for accurately detecting pipeline blockages, fouling, and the presence of gas or liquid. This non-intrusive scanning process is performed externally, meaning it requires no removal of insulation and can be done while the pipeline remains in operation. Utilizing a low-curie radioactive source, Smart Gamma™ Pipe Scan is designed to scan gas or liquid pipelines with diameters ranging from 4 inches to 72 inches.
