Corrosion Under Insulation And Atmospheric Corrosion In The Refinery Industry. An Accurate Approach To Estimate Corrosion Growth Rates, A Texas Refinery Case Study

Product Number: 51322-17751-SG

Author: Bernardo Cuervo, Mark McQueen

Publication Date: 2022

$20.00

External corrosion in uninsulated pipelines is normally able to be prevented by cathodic protection (CP). Generally, external corrosion on buried pipelines cannot occur if CP current is getting onto the pipe. CP is an electrochemical means of corrosion control in which the oxidation reaction in a galvanic cell is concentrated at the anode and suppresses corrosion of the cathode (pipe) in the same cell. For instance, to make a pipeline a cathode, an anode is attached to it.

Evaluation of Various IMM/IC Coating Systems in Terms of Corrosion Protection

Product Number: 51324-20414-SG

Publication Date: 2024

$40.00

In Oil & Gas facilities projects, coating system selection of bulk valves is challenging for EPC contractor to manage because their quantity is extensive and they are installed at each specific situation. IMM (Inert Multi Polymeric Matrix) / IC (Inorganic Copolymer) coatings, hereinafter referred to as IMM, which can be applied under various situations are anticipated to be applied for the bulk valves. Several types of IMM paints have been introduced to the market and corrosion protection performance were evaluated in this paper. Test panels of IMM coatings were prepared from five different manufacture’s brands, with variations in dry film thickness, hereinafter referred as DFT, (125µm/250µm) and with or without heat curing. Corrosion protection performance was tested by salt spray tests (720 hours, 1440 hours) and natural weathering tests (18 month), and evaluated by degree of rust, pull-off tests, and EIS (Electrochemical Impedance Spectroscopy) tests. The results of salt spray tests and natural weathering tests varied depending on each brand's product. The overall trend indicates that panels with a 250µm DFT and without heat curing panels demonstrates better corrosion protection performance rather than panels with a 125µm DFT and with heat curing. In the EIS test, some test panels showed a significant drop in impedance values at low frequency (0.1Hz) with heat curing, which may suggest a degradation in corrosion protection performance. In conclusion, it is recommended to use IMM coatings with a 250µm DFT and to be cautious when applying them at high temperature services.

Improving mineral wool CUI performance – next generation

Product Number: 51323-18959-SG

Author: Mikkel Østergaard Hansen, Soeren Nyborg Rasmussen

Publication Date: 2023

$20.00

Mineral wool has been widely used for several decades as the primary thermal insulation on piping and equipment to save energy, protect personnel, and reduce emissions. The products have been favored because they are non-combustible, cost effective, provide excellent (and reliable) thermal performance and are safe, easy, and efficient to install.

Integrity Maintaining and Cost Saving Advanced CUI Detection Technique (PEC)

Product Number: MPWT19-14242

Author: Amro Hassanein, Ahmed Elsharkawi

Publication Date: 2019

$0.00

Corrosion under insulation (CUI) is a major problem for petroleum and petrochemical process industries that affects the plant mechanical integrity and attacks assets. CUI can result in sudden and hazardous leaks (safety concern), and plant shutdowns with high losses of production (economical concern).
Traditional detecting methods of CUI to cut a window in thermal insulation used to inspect visually, to measure the thickness, and then return thermal insulation back, giving high chance for water and moisture ingress, accelerating CUI, moreover big amount of scaffolding erection along with thermal insulation removal required.
SHARQ (Eastern Petrochemical Company, one of SABIC companies) is pioneer to study CUI, evaluating many Non–Destructive techniques has proven Pulsed Eddy Current (PEC) as the most effective technique in terms of integrity and cost optimization.
Considering all available techniques, all aspects studied, such as range of applications, features, and limitations, it is concluded and verified to meet our inspection plan strategy needs.
PEC does not require thermal insulation removal; optimize scaffolding erection, has a wide range of applications related to thickness, and temperature. PEC approved by international codes and standards (API) to meet RBI Meridium software requirements.
The validation study results show cost savings of more than 50% compared to traditional thickness measurement methodology, moreover it reduces EHSS (Environment, Health, Safety, and Security) negative impact reduces the probability of safety incidents due to reducing labor, man-hours, and eliminating many associated activities with potential hazard and risk.
PEC has high productivity, easily operated, and provides comprehensive and professional inspection report

Mineral Wool CUI Mitigation Improvements

Product Number: 51324-20798-SG

Author: Ricky Seto

Publication Date: 2024

$40.00

Mineral wool has been used for well over half a century as insulation to reduce heat loss, provide personnel protection, and protect against hearing loss. Corrosion under insulation (CUI) has been a major topic of interest as process facilities age and experience issues with corrosion, particularly on pipelines. Efforts have focused on reducing any effect of the insulation material on corrosion – e.g., by reducing chlorides, making the insulation hydrophobic, and recently, by upgrading the hydrophobic performance in terms of high-temperature resistance. The next step is to introduce a proprietary corrosion inhibitor within the mineral wool. If water does make its way to the metal substrate, the inhibitor will activate in contact with water to mitigate corrosion. This paper will present the CUI-mitigating efficacy of mineral wool with an integral corrosion inhibitor using the ASTM C1617 test modified for various chloride concentrations above the standard. The paper also discusses corrosion-inhibiting mechanisms, particularly how such mechanisms can modify the environment around steel substrates to mitigate factors that advance stress corrosion cracking.

New Development in Thermal Insulation Coatings

Product Number: 51324-21011-SG

Author: Nicole Rakers

Publication Date: 2024

$40.00

In chemical process industries, oil and gas, and petrochemical plants, it is common practice to use mechanical insulation such as mineral wool or calcium silicate and metal jacketing on heated tanks, piping, and related equipment as a means of either personal protection or improved energy retention. These traditional insulation systems can become saturated with moisture, leading to significant reduction in ability to thermally insulate as well as creating an environment that may cause an increase in corrosion under insulation. To combat these issues, asset owners have also been using spray-on insulation coatings. However, these are often limited in film thickness and temperature resistance and require a primer. Recent coating technology has been developed to address these challenges currently faced in the field. This paper will discuss some of the coating’s improved properties including hydrophobicity, higher film thickness, improved temperature resistance, and direct-to-metal corrosion protection. These properties provide an asset owner the means to spray apply thermal insulation at higher operating temperatures in less coats and with better long-term protection against corrosion of the asset.
