Salt Fog Testing - Texas Style - by G2MT Labs

Salt Fog Testing of Large Components and Systems

“The Salt Fog Sauna”

Sometimes a typical salt fog tester just isn’t big enough; so we just keep making them bigger!  G2MT Labs now offers one of Houston’s largest salt fog testing units in our new 6′ x 8′ system. Engineered from the ground up by our team, this system sports a total working space of over 2,400 cubic feet; that’s big enough for a twelve-person dry sauna!

With multiple collection units, an automated heating system, and optional UV exposure capabilities, we can handle a wide range of tests including ASTM B117 and many other related standards.

“The Junior Box”

Our intermediate-size box has a working interior capacity of 24″ x 40″, sufficient for many typical jobs of 1 to 100 parts. Designed for easy access and analysis, it can be run constantly without opening the lid or can be checked daily (or more) to evaluate the onset of corrosion.

And of course, our team has the knowledge and experience to help you understand what the results mean and how to apply them. Contact us today for a quote or to learn more!

Replacing and Maintaing the Global Infrastructure

Over $60 Trillion Needed to Combat Corrosion of Global Infrastructure

A staggering new estimate of the cost of corrosion over the next 15 years says we will need to spend at least $60 trillion globally just to upgrade and maintain the existing infrastructure. This includes the cost of replacing and upgrading bridges, railroads, highways, power generation, telecommunications, and water facilities around the world. However, the recommendations suggested by this study to mitigate the problems are:

“McKinsey recommends improving:

  • Strategic sourcing
  • Demand consolidation
  • Contractor development
  • Lean execution
  • Project organization/governance planning optimization
  • Increasing infrastructure construction productivity
  • Getting more from existing capacity”

That misses the point: we need to attack corrosion at its source by understanding the likely causes of failures and preventing them. This requires a combination of efforts:

  1. Appropriate materials selection, design, and maintenance.
  2. Integrity management programs provide an effective means to predict and prevent corrosion.
  3. Just as importantly, proper design and selection can prevent many failures from occurring.
  4. Advances in the development of new steel and other metal alloys, inspection technologies, and quality assurance are all likely to provide better management and prevention of corrosion.

Metallurgists at G2MT Labs and other companies are working hard on all of these topics. What approaches do you find are most effective against corrosion?

The importance of corrosion testing

Without corrosion tests, we would expect many more failures to occur. That is the importance of corrosion testing.

Corrosion Testing by ASTM B117 Salt Fog Test

As society advances, we are continually pushing technologies to their limits. This applies to materials and metals just as well as to computers, and it means that safety is always being challenged by improvement. To meet this challenge, a wide range of corrosion tests have been created to evaluate materials performance in the simulated or real environment. Many of these tests involve simulated analyses in a laboratory to reduce or eliminate the impacts of corrosion.

We perform many different corrosion tests with goals such as: (1) determining the rate of corrosion over time – for example ASTM G31, (2) evaluating for susceptible materials such as ASTM A262, (3) analyzing the effect of hydrogen on material, and (4) assessing in-field corrosion testing. These tests often provide the critical last line of protection that prevents unacceptable materials from being used.

 

We welcome your input and comments: How have you seen corrosion testing make an impact in the world?

 

Surface corrosion of drill pipes during storage

Drill pipe failure analysis

With drilling expanding in virtually every corner of the US, including the Bakken, Eagle Ford, Permian, Marcellus, Anadarko, Niobrara, and Granite Wash plays, failure analysis is increasingly important to keep up with the rapid expansion of oil and gas drilling operations.

Drill pipe and casing failures are one of the most common types we receive for failure analysis. G2MT has performed numerous failure analysis on drill pipe and joint sections from drill strings around the US and abroad. Improper processing and/or storage resulted in early corrosion and failures in several of these cases. The improper processing was demonstrated by metallography and microscopy of the drill pipe steels and can result in cracking, corrosion, and early failures if not found before use.  In other cases, improper use of pipe in overly aggressive conditions or spinning the pipe without lubrication were the root causes of failure.

Surface corrosion of drill pipes during storageAt G2MT we provide more than just guesswork about failures,  we focus on the root cause and provide effective recommendations to solve the problem.
