Part 2 of this cathodic protection series examines how alternating current (AC) interference affects sacrificial anode performance, including polarity reversal in magnesium and corrosion rates in zinc ribbon anodes used for pipeline protection.
Cathodic protection (CP) is a technique to reduce the corrosion of a metal surface by making that surface the cathode of an electrochemical cell. The cathode in an electrochemical cell is the electrode where reduction (and no corrosion) occurs.
IMI is ready to deliver 15 QuickTrak Digital Valve Control System and Positioners for one of the world’s largest oil pipelines, which spans approximately 800 miles (1,287 km) across Alaska, marking a significant step forward in enhancing the efficiency and safety of this piece of critical infrastructure.
In 2007, the Pipeline Hazardous Materials Safety Administration (PHMSA) released a Notice of Preliminary Rule Making (NPRM), known as the Control Room Management (CRM) rule. Since the CRM rule went into full effect in 2012, pipeline operators have seen significant transformation in the control room operation.
With rising global carbon dioxide (CO2) emissions and worldwide commitment to avoid environmental impacts, the contribution of Carbon Capture and Storage (CCS) technologies is crucial. Controlling impurities in CCS pipelines is key to this effort.
Editor-in-Chief Michael Reed examines how recent West Coast wildfires exposed vulnerabilities in fuel supply chains, leading to temporary pipeline shutdowns and regional fuel concerns. While quick action restored operations, the incident underscores the importance of pipeline resilience and emergency preparedness.
(P&GJ) — Pipelines can accumulate deposits and debris, with fouling influenced by fluid composition, contaminants like hydrogen sulfide and heavy metals, and operating conditions such as temperature, pressure, and flow.
Dry gas flows can unpredictably become wet, and accidental liquids in gas transmission networks create hidden financial costs and pose serious safety risks.
PipeSense, installed three of its advanced systems across the U.S. in support of EnControl, a third-party control room company to the oil, gas and hydrogen industries.
The article examines the future of pipeline development post-TIMP rule, highlighting advancements in integrity assessments, data collection, and preventive measures. It discusses how the industry has evolved over the past 20 years and the potential for future improvements in pipeline safety and technology.
Pipelines play an integral part in modern industry. They help transport essential resources like water, oil, and gas across vast distances, ensuring facilities stay functional and operational.
(P&GJ) — Innovative inline inspection technologies NDT Global launched a 56-inch ultrasonic inline inspection tool, which was developed in collaboration oil and gas company Aramco.
Risk models are prominent pipeline integrity management (PIM) tools used to make data-driven decisions. As computing power has increased and data acquisition methods have proliferated, risk models have become more complex.
The pursuit of building a better mousetrap can often pay off in big ways in terms of efficiencies. Such a productivity payout was the goal for finding a better solution for coating pipeline girth welds in the field – a solution that would speed up the coating process per weld.
