Non-Destructive Testing Methods for Coke Drum Inspection
In the oil refining process, coke drums play a key role, especially in the delayed coking unit, where the heavy oil residue is converted into lighter hydrocarbon products and petroleum coke. These drums operate under extreme conditions of cyclic thermal stresses, high temperatures and pressures, making them susceptible to various types of service failures.

Phase Array Ultrasound (PAUT) in corrosion control of minor pipelines
Author: Ing. Carlos Alvarez, 06 March 2024.
Corrosion control is a problem in industries, especially in sectors that depend on pipelines for the transport of fluids such as oil, gas and water, such as the petroleum, petrochemical and nuclear sectors. Internal corrosion of pipelines, if not properly controlled, can lead to catastrophic failures, environmental damage, loss of life and large financial losses.
