Integrity

Current Magnetometry Inspection (CMI) uses multi-frequency AC fields, AI/ML, and dense aboveground sensing to 3D-map pipelines, calculate EIR-free, and distinguish passivated versus actively corroding defects—enabling targeted digs on unpiggable lines without disrupting CP or operations.

Incorrect internal diameter specifications in insulating gasket kits can cause electrical bridging and galvanic corrosion at pipeline flanges. Saudi Aramco engineers explain how proper bore sizing and torque control are critical to maintaining electrical isolation and long-term integrity.

Pipeline operators are turning to thermal insulative coatings (TICs) to combat corrosion under insulation (CUI) and prevent heat loss. These advanced coatings provide long-term protection, improve energy efficiency, and eliminate moisture-trapping insulation systems prone to corrosion and failure.

A new reliability study from Universidad Nacional de Colombia analyzes how slow crack growth (SCG) and burial design variables—such as soil class, depth of cover, and trench width—affect the long-term performance of HDPE pipelines. Using Monte Carlo simulations and machine learning, researchers identify key factors influencing pipeline failure risk.

EUROPIPE expert Christoph Bosch outlines a new toughness model using drop-weight tear testing to improve safety in CO₂ pipelines, addressing limits of traditional Charpy impact tests.

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.

Learn how utilities and processors use modern gas analysis technologies, including tunable diode laser absorption spectroscopy (TDLAS), to detect and remove contaminants like H₂S and ensure natural gas purity across the U.S. pipeline grid.

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.

(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.

The Charlotte-based Piedmont Natural Gas utility field representative is a serial hero, having performed three life-changing heroic acts in 2023.

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.
