AC Modeling Introduction Video
This training video introduces AC modeling for pipelines affected by high voltage transmission line interference. It explains when a best-guess mitigation approach is appropriate versus when detailed computer modeling is warranted to evaluate induced voltage, fault current, and step and touch potential impacts.
PHMSA Rule Making Updates – a look at what is ahead on the US Regulatory Front
The US pipeline regulatory environment was moving toward new PHMSA rules expanding integrity management and safety requirements. This article reviews key pending changes, including the Liquids Final Rule that extended integrity management and leak detection obligations beyond high consequence areas.
Pipeline Cathodic Protection Design for New Transmission Stations
Growth in US pipeline construction has increased demand for cathodic protection engineering at new transmission stations. This article describes MATCOR’s approach to cathodic protection design for new compressor and pump stations, including the installation advantages of linear anodes in new construction environments.
CP Introduction Video
Created as an internal video to train employees, this video is great for anyone that wants to understand the basics of cathodic protection.
Anode Current Ratings and Soil Resistivity
Anode current ratings are based on expected service life in amp-hours, not soil resistivity, which only affects circuit resistance. This article explains anode life calculations for magnesium and mixed metal oxide anodes and clarifies the distinction between current rating and operating resistance.
Quick Ship Cathodic Protection for Tanks
MATCOR’s Quick Ship program for tank cathodic protection maintains stock of its Tank Ring Anode System for rapid delivery when above ground storage tanks are unexpectedly taken out of service. Pre-assembled systems for tanks up to 200 feet in diameter ship from Chalfont, Pennsylvania with a two-day turnaround.
Deep Anode Comparison: 9 Reasons Durammo Beats Conventional Systems
The Durammo Deep Anode System is the only factory-assembled, ready-to-install deep anode system, eliminating the field assembly required by conventional designs. This article presents nine performance and installation advantages of the Durammo continuous wire anode over traditional deep anode systems.
MATCOR Now Part of BrandSafway Integrity Services Group
In January 2018, BrandSafway formed the Integrity Services Group, combining MATCOR’s cathodic protection services with LDAR and industrial specialty services. The group was created following the 2017 merger of Brand Energy and Infrastructure Services with Safway Group to form BrandSafway.
AC Interference – Basic Theory | Video Training Course
This 16-minute AC interference training video covers three primary effects on buried pipelines: the 15-volt safety threshold, fault condition interactions including conductive coupling, and AC induced corrosion. The course explains how high voltage power lines in shared corridors interact with parallel pipelines.
AC Modeling – The Basics
AC modeling evaluates the impact of high voltage AC transmission systems on buried pipelines sharing a right of way. This article explains how computer-based models assess steady-state induced current, fault current effects, and safety risks to above-ground appurtenances along pipeline corridors.
6 Sled Anodes Replace 274 Galvanic Anodes for Marine Jetty Corrosion Protection
MATCOR’s Sea-Bottom impressed current anode sleds protected a steel pile jetty in Indonesia, replacing a galvanic design that would have required 374 aluminum anodes. Six sled anodes were installed in three days, demonstrating a cost-effective alternative to galvanic cathodic protection for marine structures.
Remediation Options for Aging Pipeline Coating Systems
As pipeline coating systems age and degrade, operators must evaluate remediation strategies to maintain pipeline integrity. This article examines two approaches—pipeline recoating and linear anode installation—as alternatives for managing aging pipelines with deteriorating external coating systems.
