Guidelines for Using Water Analysis for Corrosion Prediction- Sampling Analysis and Data Interpretation

Product Number: 51323-19421-SG

Author: Y. Zheng, J. Sonke, B. Brown

Publication Date: 2023

$20.00

Various corrosion prediction tools for CO₂/H₂S corrosion have been developed in the past thirty years. For corrosion analysis in oil and gas production, the water chemistry largely determines the corrosion rate which is mainly driven by in-situ pH.

The in-situ water or brine is pressurized with acid gases (CO₂/H₂S) which results in a decrease in pH and typically an increase in the corrosion rate.

How Fluoropolymers Resist Chemical Attack across the pH Spectrum

Product Number: 51324-20603-SG

Author: Jason Knapp

Publication Date: 2024

$40.00

When chemical process systems require extremely harsh or demanding environments, material selection is critical for providing longevity and preventing downtime. For systems utilizing exceedingly low or high pH chemicals, fluoropolymers are often an excellent choice to prevent corrosion in a system. The strong carbon-fluorine bond allows fluoropolymers to thrive in areas where other materials would be subject to failures. Strong acids are handled exceptionally well by many fluoropolymers, and certain copolymerization reactions with materials such as PVDF can provide a material that holds up to even more challenging situations. This paper will summarize the most commonly used fluoropolymers in the industry, as well as discuss applications where fluoropolymers are used. The paper will also detail why fluoropolymers can resist exceptionally aggressive chemicals, and how PVDF-HFP copolymers improve the corrosion resistance of both low and high pH environments. Case studies will also be provided.

Laboratory Study of Internal Corrosion and Cathodic Protection Concerns Related to Offshore Monopile Structures

Product Number: 51323-18894-SG

Author: Suresh Divi, Adam Rowe, Dan Efird

Publication Date: 2023

$20.00

There have been several studies and publications over the past decade that clearly illustrate how initial assumptions about monopile interiors being perfectly sealed compartments were not correct in practice. Oxygen ingress through various points in the monopile contributes to persistent internal corrosion, and planned inspections are also opportunities to introduce fresh oxygen into the monopile. The replenishment of oxygen has been found to continue the corrosion reaction between the monopile wall and entrapped water.

Potassium Hydroxide For PWR Primary Coolant pH Control: EPRI Program

Product Number: ED22-17394-SG

Author: Keith Fruzzetti, Dennis Hussey, Peter Chou, David Perkins

Publication Date: 2022

$20.00

This paper outlines and summarizes the robust testing and assessment program developed and implemented by the Electric Power Research Institute (EPRI), following upon an initial feasibility evaluation completed in 2015. A multi-year, multi-discipline program has been developed, incorporating significant industry input, to address the identified technical gaps in materials, fuels, chemistry, and radiation safety that need evaluation to support a plant demonstration in a Western-design PWR.

Weld Jointing Influence on Boiler Tube Sheet Integrity

Product Number: MPWT19-14366

Publication Date: 2019

Boiler system is one of the most critical systems for a utility plant. A utility plant had experienced high percentages of boiler downtime owing to boiler tube sheet cracking failures. Investigations carried out revealed high stress at the tube-to-tube sheet joint in the boiler fire-side entrance. Tube-to-tube sheet joints at the boiler fire-side entrance had been fabricated by strength welding and without any expansion. The strength welded joint had created undue stress leading to cracking of the weld joint by thermal expansion. A higher quality expanded joint consisting of expanding, flaring and seal welding the fire-side entrance was implemented during the re-tube process. The utility plant has now zero downtime due to boiler tube failure. This article summarizes the description and history of failures with the boiler at the utility plant; investigations and corrective actions carried out; and the present improved condition of the boilers.
