Pipeline scale and blockage inspection

Pipeline scale and blockage inspection

     Inheriting the research from the parent company – Chugai Technos Corporation in Japan, we would like to introduce the pipeline blockage inspection service. Through Scale Checker device, know the status, scale, rate of adhesion, sticking and accumulating in the pipeline. Through the processing software on the computer, the status of adhesive and scale will be displayed on the screen. Furthermore, it is possible to analyze composition of the scale and show it at the elemental level.

Measurement principle

Video demo Scale Checker


  • The source and the detector are set or either side of pipe and moved parallel to sectional direction, then an amount of scale is estimate by measuring the stregnt of radioactive ray passed through at each scanning point.
  • Measuring can be performed without removing the heat insulation and disassembling pipe, possible even existence of fluid in the pipe.
  • It is so easy to get measured data and imaging picture in field that the judging can be obtained immediatly.
  • Measured data can be stored by computer, therefore the hard-copy can be obtained later, for edit at office.
  • Software is conversation-type to operate convinently.

Material: Steel pipe (carbon steel pipe, SUS steel pipe), PVC pipe, etc.

Pipe size

  • In the case without fluid in the pipe: Diameter 50 – 600 mm.
  • In the case existence of fluid in the pipe: Diameter 50 – 300 mm.


     Check the scale deposition and clogging of various plant’s pipelines, seawater pipeline, (shellfish adhesion), powder transport pipeline, gas pipeline, water supply and drainage pipeline, cooling and heating pipeline, hot spring pipeline, etc.
