engineers meeting pipes


Behind the technical reason for a failure, there resides a lack of technical curiosity, a search for the truth and, ultimately, a lack of consensus.

How Better Industry Teamwork Can Reduce Premature Coating Failures


Pitfalls often plague the success of coatings application projects, resulting in costly premature failures across numerous industries. We examine some solutions.

Corrosion Resistance in Reinforced Concrete Structures


Although steel reinforcement is embedded in the concrete, it is still vulnerable to corrosion. This corrosion deteriorates the bars and reduces the overall load carrying...

The Impact of Minimum & Maximum DFT Values on Coating Performance


Two leading marine coating experts illustrate how to assess and control a myriad of painting process variables using a simple control chart showing the impact of...

How Hydrophilic Coatings Are Effectively Protecting Against Copper Corrosion in High Temperature and Salty Environments


Copper it is not hydrophilic, making it unsuitable for some applications in hot, humid or salty environments. Various surface treatment methods and coatings are being...

The Composition of a Paint Coating


A coating is a substance spread over a surface to provide protection or to serve decorative purposes. Here's an overview of paint coatings, particularly industrial...

The Tuberculation Battle: How to Effectively Use the Unidirectional Flushing Method


Tuberculation is a common problem associated with aging metal iron pipes. In an attempt to improve operational efficiency and overall water quality standards,...

Evaluating New Trenchless Technology for Water and Wastewater Pipeline Infrastructure


New economical rehabilitation technologies show promise in extending the operation life of critical assets. A review of a recent EPA study on two commercially available...

How to Prevent Premature Coating Failures by Removing Soluble Salt Contaminants during Surface Preparation


Here we offer a proven way to remove what is known and documented to be a leading cause of premature coating failures — soluble salt contamination.

The 4 Best Nondestructive Inspection Methods for Corrosion Under Insulation


The advantages and limitations of four of the best nondestructive inspection methods for corrosion under insulation (CUI) in pipelines are examined.

7 Best Methods for Detecting Leaks in Pressure Vessels


Pressure vessels may become unusable if leaks are present and the internal pressure decays. It is critical that pressure vessels remain sealed and there are no leaks...

Increased Rates of Copper Corrosion in the Zone of Aeration Explained


Variation in environmental conditions tends to create conditions ideal for the formation of differential aeration cells in the zone of aeration and lead to corrosion of...

10 Best Ways to Prevent Gusset Plate Corrosion


Gusset plate corrosion can cause a reduction in load carrying capability and ultimately lead to a collapse of the structure. Steps should be taken to address the types...

Why One Insulation Material Does Not Fit All Applications


Johns Manville Industrial Insulation Group explains why there isn’t a single insulation on the market today that will provide optimal performance in all conditions.

CUI Myth: Shop Coatings are Better Quality than Field Coatings


If you have a controlled environment, you’re much more capable of controlling (and thus optimizing) the quality with which a coating is applied—right? Nothing could be...

What are the benefits of using refractory metals?


Refractory metals are a classification of metallic elements that possess properties that make them more durable and resilient than other standard metals. While the...

How can I avoid galvanic corrosion?


Galvanic corrosion is a destructive electrochemical process that occurs when dissimilar metals are in direct or indirect contact with each other with an electrolyte...

What are the different Xylan coatings and how do I decide which is best?


Xylan is an industrial dry film lubricant consisting primarily of one or more fluoropolymers including polytetrafluoroethylene (PTFE), perfluoroalkoxy alkane (PFA) and...

What is a biofilm and how does it contribute to microbiologically induced corrosion?


Biofilms are deposits of biological origin that form on surfaces such as the inside walls of pipes, process vessels, storage tanks, condensers and pumps. (Corrosion in...

What is the significance of the high temperature range when considering corrosion under insulation (CUI)?


Corrosion under insulation (CUI), like other forms of corrosion, is electrochemical in nature and therefore is significantly influenced by the temperature of the...
