Pipeline Specialized Surveys

Pipeline Specialized Surveys

SARK provides specialized pipeline surveys to monitor the efficiency, productivity and output of Cathodic Protection systems.This is essential to any Cathodic Protection program and ensures the continued operation of your facility.

Soil Resistivity

It gives us an idea of the corrosivity of soil. The soil resistivity indicates the relative capability of the soil to conduct electrical current. Higher the current, higher is the corrosion.

CIPS

Close interval potential survey is carried over the entire length of the pipeline to identify the if the installed CP system is providing the required protection against external corrosion.

Current Attenuation Test (CAT)

The main objective of CAT Survey is,

  • To identity of pipeline sections where coating deterioration is expected.
  • To estimate the health of the pipeline coating.

Direct current voltage gradient (DCVG)

A direct current voltage gradient (DCVG) survey is a type of survey method that is used to find the effectiveness of coating on buried pipelines. This is highly useful in the natural gas and oil industries, as this technique is used to trace and pinpoint the coating faults.

External Corrsion Direct Assessment (ECDA)

The assessment involves estimating the remaining life of the existing structure and the remaining strength.

Ultrasonic Thickness Measurement

This method involves the measurement of metal thickness of structures such as pipeline, steel plating insides, tanks, decks, superstructures, etc. The purpose is to determine the extent of corrosion on the structure and to estimate its remaining useful life.

Coating Peeling Test

Coating Peeling Test is to determine the bond strength between the coating and the metallic structure. It is an essential aspect of assessing the products’ overall quality.
