Radial Interaction for Corrosion Defects in Offshore Pipeline

Carbon steel pipeline had been trusted as the most reliable and safest way to transmit the fluid from the sources to the consumers. Like any other structural behaviour, this carbon steel tends to fails and require further maintenance after certain period of time. One of the major threats that cause...
