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

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
