The Mike Rohe Foundation Changed My Life!

The Mike Rohe Foundation Changed My Life!"I started this journey with a mountain high of inspiration, but with no hope of financial realism. I knew I was certain about starting a career in NDT.

But, it takes money to earn money. I had no idea how I was going to be able to afford my education. Then I saw a commercial about the Mike Rowe scholarship foundation. I knew this was my shot to try and pursue after the education I wanted/needed.

I contacted my Mike Rowe foundation and submitted my application. I was nervous at first, had no idea what to expect, or even what to do. They made it easy, walked me thru the application steps, and kept in steady contact with me in term of the progress.

The day I found out I had been accepted, I was overjoyed, and in disbelief. I had to let reality sink in. Applying for the Mike Rowe foundation was absolutely the best decision vie ever made, it was life changing! Word can’t explain how thankful and fortunate I am to have this opportunity. And as I write this, I am full speed into my career and loving the NDT field."

How Low Temperatures Impact Dye Penetrant Testing

In this article, we look at how lower inspection temperatures affect the performance of dye penetrant testing cleaners, penetrant and developers

The operating temperature range for penetrant inspection as specified in ASTM E1417 Standard Practice for Liquid Penetrant Testing is 40°F to 125°F (4°C to 52°C), but how is the penetrant inspection affected at temperatures below 40°F (4°C) and can the inspection process be adjusted to achieve acceptable results?

To answer these questions, we evaluated SKC-S cleaner/remover, SKL-SP2 solvent removable dye penetrant and SKD-S2 non-aqueous developer at a range of temperatures in order to figure out what NDT inspectors can expect when using these, or similar quality dye penetrant products when inspecting at lower temperatures

Cleaning at lower temperatures

At lower temperatures in the range of 32°F – 50°F (0°C – 10°C), the solvent cleaner will take longer to dry.

We used 75°F (24°C) as our ambient, standard operating temperature, and observed how decreasing temperatures impacted how quickly the solvent cleaner dried. Below are our suggested drying time for solvent-based cleaner/removers at lower temperatures.
 

TemperatureCleaner Drying Time
75°F / 24°C Standard
50°F / 10°C 2 x Standard
40°F / 4°C 3 x Standard
32°F / 0°C 4 x Standard

It is critical to make sure the solvent has evaporated during the precleaning step either by wiping with a clean, lint free cloth or using air dryers to ensure a clean and dry part prior to penetrant application. Unevaporated cleaner remaining in indications can impede penetrant entry into the surface breaking indications.

Dwelling at lower temperatures

Penetration time should also be extended since the viscosity of penetrant increases with decreasing temperatures, which slows down penetration and can significantly impact the test results.
 

TemperatureDwell Time
75°F / 24°C Standard
45°F / 7°C 2 x Standard
32°F / 0°C 2.5 x Standard

Developer at lower temperatures

Developer drying time is more of a challenge and our tests showed the developing action is impeded because of the slower solvent evaporation. When the developer dries, the indications become fuzzy or show excessive bleed out.

Penetrant Developer

We were not able to get good results at 32°F (0°C) because the developer remained wet and did not dry within a reasonable amount of time. At 38 – 40°F (3 – 4°C), and with some air movement, developer film will dry at 5 times the standard time at 75°F (24°C).
 

TemperatureDeveloper Drying Time
75°F / 24°C Standard
40°F / 4°C 5 x Standard

A positive note is at low temperatures, we found good indications with extremely small and tight defects. The slow drying rate of the developer film allows greater bleed out of the penetrant from the defect. For large defects, longer development time caused excessive bleed out making indication interpretation more difficult.

Exposing 10 Common Misunderstandings about Penetrant Testing

We reveal common penetrant inspection misperceptions we’ve seen in the field in recent years

The liquid penetrant method of nondestructive testing has been used since the 1940’s. But even after being used by generations of NDT professionals, there are still some common areas of confusion or misunderstanding.

Here we set the record straight on 10 misperceptions we’ve seen in the field in recent years.

 

1. The highest sensitivity penetrant is the best penetrant for my application

The best penetrant for an application is the one that finds the right indications with the least amount of money and time. Sometimes this means not using the highest sensitivity penetrant.

While it is true that a higher sensitivity penetrant will produce indications for very small discontinuities, a higher sensitivity penetrant will probably not give you the best inspection results if you only need to find medium discontinuities since you will see far more indications than are relevant to the inspection.

To start selecting a penetrant, review any governing specifications and work procedures for required sensitivity levels.

Take into consideration the surface finish and configuration of the part.

A high sensitivity level fluorescent penetrant is appropriate for smooth, highly machined surfaces. However, a high sensitivity level fluorescent penetrant may leave excessive fluorescent background on a rough cast part, making inspection difficult. 

A lower sensitivity fluorescent penetrant is a better choice for rough surfaces.

 

2. A penetrant indication is a discontinuity

A penetrant indication is the visual results or response of the penetrant test which must be interpreted to determine its relevance.

Penetrant indications must be evaluated by a qualified inspector to determine if they are nonrelevant or relevant.

Nonrelevant indications may be present on parts because of inherent surface roughness or seams. Fingerprints or fibers may also cause nonrelevant indications.

Relevant indications are the result of a discontinuity, or interruption in the physical structure of an object, and are evaluated according to acceptance criteria. After evaluation, the part is accepted as is, reworked or discarded.

 

3. Water washable penetrants are water based

Some water washable penetrants are water based. However, this is not always the case. A penetrant can be water washable and not contain water.

Water-washable penetrants contain surfactants which allow the penetrant to be easily removed from the part surface with water rinsing, regardless of if they are water-based or oil-based.

 

4. Penetrants are only used on nonferrous metals

Penetrants can be used to inspect ferrous and nonferrous metals.

Penetrant inspection will find discontinuities open to the surface on ferrous and nonferrous metals.

Penetrant testing should not be done on porous surfaces, as the pores will act as discontinuities to trap penetrant and prevent accurate inspection.

 

5. Penetrant will be able to penetrate a discontinuity that contains water

Penetrant cannot seep into a discontinuity if it is already filled with water or other liquid.

Likewise, penetrant will not displace or penetrate through paint, particulate, oil or grease.

This is one of the reasons why an important prerequisite for a valid penetrant inspection is to start with properly cleaned and dried parts.

 

6. Tanks and an inspection booth are required for penetrant inspection

Penetrant inspection is easy to adapt to different environments and job sites.

Penetrant inspection systems with stationary tanks and booths are commonly seen in production environments. However, both fluorescent and visible dye penetrants are available in aerosol cans and kits for convenience and portability.

 

Check out our Penetrant Process Guide for a visual reference outlining each step in the various penetrant inspection methods and to learn 5 tips for penetrant testing

 

7. Penetrant is all that is needed to perform a penetrant inspection

At a minimum, penetrant and developer are required to perform a water washable penetrant inspection.

Additional products such as cleaner/removers and emulsifiers are required for solvent removable and post emulsifiable penetrant inspections.

 

8. Special lighting is required for penetrant inspection

Fluorescent penetrants do require inspection in a darkened area with specification compliant UV lighting. The UV lights may be mounted or hand-held for flexibility and portability.

Visible dye penetrants only require adequate white light, typically 100 foot candles minimum, for inspection.

 

9. Penetrant inspection should be the final check in a manufacturing process

Penetrant inspection is useful immediately after any manufacturing process which is known to cause discontinuities. This allows parts to be reworked or discarded earlier in the manufacturing process, which saves time and cost.

Penetrant inspection may sometimes be performed more than once during the manufacture of a part.

The placement of each penetrant inspection process should be optimized to locate manufacturing-induced discontinuities and reduce the amount of scrap or rework done later in the manufacturing process.

 

10. Penetrant inspection can take place at any point in the manufacturing process

As discussed, it is important to perform penetrant inspection after manufacturing operations likely to cause discontinuities open to the surface in parts.

However, care must be taken to perform penetrant inspection prior to mechanical operations that will smear the metal surface. Machining operations such as shot blasting, peening or grinding may close surface discontinuities, which can prevent subsequent penetrant inspections from finding these discontinuities.

Penetrant inspection should take place before machining operations like shot blasting, peening or grinding unless chemical etching can be used between these operations and the penetrant testing to reliably expose the discontinuities.

9 Transparently Amazing Facts About X-Rays

9 Transparently Amazing Facts About X-RaysIn 1895, Wilhelm Roentgen, a professor of Physics in Worzburg, Bavaria, was the first to find a way to peer inside the body without surgery. On the evening of November 8, he was experimenting with the conduction of electricity through low-pressure gases using an induction coil and a partially-evacuated glass tube when he accidentally discovered a mysterious ray capable of lighting up a fluorescent screen a few meters away.

On the evening of November 8, he was experimenting with the conduction of electricity through low-pressure gases using an induction coil and a partially-evacuated glass tube when he accidentally discovered a mysterious ray capable of lighting up a fluorescent screen a few meters away.

When he passed his hand between the ray and the screen, he glimpsed a shadow of his own bones. Further experimentation showed that the screen could be replaced by a photographic plate—and the x-ray was born. Roentgen would later earn the first Nobel Prize in physics for his discovery.

Corrosion Under Insulation: The 7 Inspection Methods You Must Know About

Melissa Syvrais | Apr 14, 2016
https://www.linkedin.com/pulse/corrosion-under-insulation-7-inspection-methods-you-must-syvrais-1

April 4, 2016 - Author: Charles Tremblay

As we discussed in our previous article, corrosion under insulation (CUI) is one of the most difficult corrosion processes to prevent. The reason for that is, by and large, no matter the precautions taken, water invariably seeps into the insulation and begins its dirty work—sometimes unseen until process leakage occurs. Data shows that about 60% of pipe leaks are caused by CUI. That’s not good.

CUI is difficult to find because the insulation covers the corrosion problem until it is too late. Removing insulation, inspecting, and then reinstating the insulation after inspection is an expensive process. Inspecting without removing insulation and weather jackets greatly reduces the cost of inspections. Non-destructive testing methods to detect CUI in such a way is therefore a major benefit to the industry.

There are a number of methods used today to inspect for CUI. No one method is ever used by itself—several methods complement each other for optimal results, but that’s not the object of this article.

The most common and straightforward way to inspect for corrosion under insulation is to cut plugs in the insulation that can be removed to allow for ultrasonic testing. The other commonly used methods are radiography, and complete insulation removal. More advanced methods include pulsed eddy current. CLICK HERE to read the seven most common methods of inspecting for CUI with their pros and cons.

"NDT training services market is expected to grow at the highest rate during the forecast period"

"The demand for NDT services would increase in the near future owing to the aging infrastructure and the increasing rate of new infrastructure development. Moreover, owing to the shift to advanced NDT techniques, such as phased array ultrasonic testing (PAUT) from traditional NDT techniques; there would be a need for skilled technicians. As a result, the NDT training services market is expected to grow because of the shortage for trained technicians for conducting NDT inspections in the NDT market.
"Oil & gas sector is expected to hold the largest share during the forecast period"

The demand for NDT technologies in the oil & gas sector is largely driven by government regulations for improving the safety of people and environment by avoiding oil spillage due to leaks, bursting of pipes, or any other accidents. As majority of the piping infrastructure and refineries are timeworn, it is imperative to conduct regular NDT inspections to ensure the integrity of these assets. The fall in oil prices since the end of 2014 are not expected to significantly impact the demand for NDT inspection on existing infrastructure. Thus, the oil & gas sector is expected to remain the largest market for NDT during the forecast period."
