The use of multi-sensors for underground corrosion control is a cost-effective method for providing several different types of data that more fully characterize conditions at the structure.

Isolation plays a vital piece in the fight against corrosion. However, isolation in a cathodic protection system is not always used, isolation kits may malfunction, and/or an isolating kit may be found to not be isolating and might be replaced by a non-isolating gasket.

Companies across many industries use internal coating corrosion inhibitors today. These inhibitors are especially effective at protecting steel pipelines and vessels - they create protective films on the insides of these structures to prevent corrosive substances (e.g., oxygen in water, bacteria, and hazardous gases) from coming into contact with pipe surfaces.

Telluric activity induces time-varying electric currents that affect virtually every buried metallic pipeline on Earth to some degree.

The carbon steel pipes of the Cunduacán I Compression Station operate in a very corrosive environment. The challenge faced by conventional protective coatings is the continuously wet surface of the pipe.

Gaskets have been used for many years to disrupt the electrochemical pathway between anodes and cathodes in bolted joints. However, the gasket must maintain its primary objective which is providing a leak tight seal, while being electrically insulating.

This paper is intended to educate the reader on some common issues that influence interrupted surveys, existing solutions to these issues, and a description of how the PCRX provides value in its groundbreaking approach to solving a key issue with interrupted surveys. For the purposes of this paper, underground pipelines will be the targeted protected structure.

The passage of time inevitably takes its toll on the integrity of assets. Corrosion, in all its forms, is one of the most significant time-dependent pipeline degradation mechanisms, compromising the integrity of our pipelines and potentially reducing their remaining service life. The challenge for us, as pipeline engineers, is clear: to safely manage our pipeline infrastructure into the future.

Pipeline operators have realized tremendous cost efficiencies by collocating in the same corridors as high-voltage alternating current (HVAC) lines, but evolving and difficult challenges exist within these applications to protect against pipeline corrosion and safety hazards.

Stone wool insulation possesses unique physical properties that make it ideally suited to a number of industrial applications including petrochemical processing. The open cell structure of stone wool encapsulates and restricts air movement, which gives it excellent insulation capabilities, while still allowing for water vapor to freely pass through.

Electrochemical methods provide an alternative to traditional methods used to determine the rate of corrosion. Direct and quantitative determination of corrosion rates can be determined from simple electrochemical measurement like Linear sweep voltammetry

How well does a plastic isolation gasket with filler fair in today’s oil and gas pipelines? This paper , will analyze the chemical compatibility, the temperature resistance, the pressure resistance, the emissions capabilities and even the ease of installation of these materials.

Almost every man-made structure involves the use of metals; often, non noble metals that are susceptible to corrosion. The estimated worldwide costs for corrosion derived damages are about 2.5 trillion dollars. Proper corrosion protection could save 15–55% of the cost of these damages.

PTASCC occurs by the combination of 3 factors; formation of Polythionic acid due to exposure the metal sulfide scale to oxygen and water in the aqueous phase, residual tensile stress and sensitized microstructure having the Cr carbide precipitation at the grain boundary by welding.

Historically, the Cathodic Protection (CP) industry has lagged behind the technology curve. It has taken years for technicians to ditch their Big Chief tablets in favor of more modern data acquisition tools. As pipeline operators have started to adopt relevant technology for gathering and storing CP data, workflow efficiency has increased. But those technologies are not always fully leveraged to improve data quality.
