Abstract
Pipings and pipelines are vulnerable to internal and external corrosion and subjected to deposit
accumulation because of chemical effects. Determining the extend and progress rate of
corrosion and deposit provides useful information about the operational life and safety of the
equipments and plants.
The condition of pipings and pipelines can be monitored by the proper use of non-destructive
inspection methods even while the plant is in operation.
Pitting is a special kind of corrosion, which is very often encountered in pipes. Detection of
corrosion pits in pipes can easily be performed by using tangential radiographic and film density
measurement methods. Detection of pits, which are associated with deposit can not be directly
performed by density measurement method and requires special simulations. This study
describes the determination of depths of pits in pipes associated with deposit by radiographic
density measurement method. Special simulations were made in order to obtain density-deposit
thickness reference curves for the evaluation of deposit thickness and thus pit depth. Difficulties
and limitations of the method were discussed.
