Gamma  Scanning of Industrial Process Columns

Gamma Scanning of industrial process columns is a useful NDT tool for visualizing the column internals without shutting down or opening the columns. It can detect the cause of malfunction in columns / packed beds like;

  • Location and extent of flooding/weeping.
  • Presence or absence of trays or other internals.
  • Liquid levels on trays and packed column liquid distributors.
  • Location and density characteristics of foaming.
  • Position of packed beds.
  • Extent of liquid misdistribution in packed beds.

The advantages of the system are:

  • On-line and non-destructive hence cost-effective
  • Assesses column hardware and general health
  • Helps in scheduling/predictive maintenance
  • Helps in optimization of process parameters

Pipe Scanning

The deposition of solids on the walls of pipes and vessels, whether insulated or otherwise, leads to partial/complete blockage and are frequently sources of major plant problems in chemical and petrochemical industries.

Pipe scan in progress -

Gamma-ray absorption techniques are useful in investigating the blockages in pipelines. Pipe scan provides a rapid means of locating and measuring the thickness of deposits in pipes on-line.

Radiometry of Shielded Containers

Radiometry inspection is carried out for the purpose of detecting internal discontinuities like cavities, blowholes, voids etc. Radiometry of following structures are carried out:

  • Lead filled vessels, doors and panels
  • Lead bricks
  • Hot Cells
