Guided Wave Technology Aims To Help As ECDA Tool

E-mail Print PDF

Another tool to help the direct assessment of external pipeline corrosion appears to be gaining the attention of operators. Long-range guided wave ultrasonic testing (LRGWUT) technology is being viewed more widely as another tool to help. The increasing visibility of the technique can be attributed to capability improvements, an increased understanding of the decisions that must be thoughtfully made about where to use the technology and, equally important, the importance of employing professional data interpretation.

New Soil Corrosiveness And External Corrosion Rate Model

E-mail Print PDF

This article examines how soil corrosiveness and pipeline corrosion rate data support integrity management programs. Pipeline integrity management programs address a wide range of threats to safe operation. Among these threats is external corrosion of buried steel pipelines. While external coatings and cathodic protection (CP) are typically used to mitigate external corrosion, corrosion can result from the combined presence of degraded coatings and inadequate CP.

Lab Testing Reveals Relationships Among Soil Quality, Corrosion And The Pipeline Environment

E-mail Print PDF

While most operators understand the importance of acquiring data to efficiently manage the integrity of their pipeline systems, many are unaware of laboratory testing procedures that are available to help guide risk and integrity management. This article will look at lab testing capabilities related to corrosion and integrity that can benefit the pipeline and gas distribution industry.
