AUT - Time of Flight Diffraction on ndt.net

TCR Engineering Services, as an NDT services company, routinely provide AUT using ToFD in India and Saudi Arabia. I wanted to give something back to the outstanding forum on ndt.net and thought that one of the best ways will be to create a compilation of answers on ToFD that are so frequently asked on ndt.net.  I plan to update this thread as time permits so that we can all benefit from the collective wisdom of the contributors of this forum. Here are links and brief outlines to important discussions on Time of Flight Diffraction:

 

Sizing a Defect using ToFD

Contributor Suresh on ndt.net writes:

However, over the last 20 years, TOFD has probably been used more in validations, round robin trials et cetera than any other NDT technique. From this, we have established that TOFD is probably the most accurate sizing technique for embedded defects presently available to the world. A recent test for a major oil company we did on some 30 rootcracks in thin walled material, which were compared to physical measurements after destructive testing showed a mean error on height sizing for TOFD of 0.27 mm with a standard deviation of 0.7 mm. The X-Ray results obviously did not give any height measurement. On the length measurement the accuracy of TOFD was 2.6 mm, with a standard deviation of 4.5 mm. For X-Ray the accuracy of the length measurement was -19 mm (undersized) with a standard deviation of 43.5 mm. By the way, X-Ray only revealed 55% of the cracks, whereas TOFD found 97%.

 

Demonstration of technique as per 2235-9

Contributor Ed Ginzel writes:

The method of sizing (vertical extent?) for CC2235-9 for examining pressure vessels with a thickness over 13 mm needs to be qualified (demonstrated).  It states in i)(3) Flaw Sizing. Flaws shall be sized in accordance with a procedure demonstrated to size similar flaws at similar material depths. Alternatively, a flaw may be sized by a supplemental manual technique so long as it has been qualified by the demonstration above.

 

Dead Zone Calculation

If I were to bet, this thread is the longest and most frequently asked question with respect to ToFD.

Tom Nelligan of Olympus NDT wrote:

Dead zone -- the interval following the excitation pulse in which potential exchoes are obscured by ringdown -- is a property of BOTH the probe and the instrument. The response of any transducer is highly dependent on how it its pulsed. Changing pulse energy, type (spike, square wave, or tone burst), and damping, as well as receiver gain and filtering, will have a significant effect on the excitation pulse ringdown envelope and hence on dead zone length. As others have suggested, your best approach is to simply measure it under your actual test conditions using appropriate reference blocks.

 

Ed Ginzel wrote

The "missed data" would be the dead zone. This is not actually a function of the wall thickness but instead, the ring time equivalent depth of the pulse. Frequency, probe spacing and angle used can all be factors. A simple calculator is provided as a download on NDT.net to estimate the Dead Zone heights associated with TOFD setups.

 

Smallest detectable flaw using TOFD

Ed Ginzel once again has a truly informative posting where he mentions:

In clean low carbon steel I have “detected” pores on the order of 0.2mm diameter using a 5MHz TOFD. That is on the order of 5-6 times smaller than the wavelength! But when the same TOFD technique is applied to austenitic stainless steel with grain size on the order of 50-100 microns, the scatter makes it virtually impossible to detect anything but the largest of flaws. Grain size in chrome stainless steels are typical of this order of magnitude. (see http://www.ultrasonic.de/abstract/wcndt96/data2/165.htm)

Properties of the materials tested (not just the alloy, since an alloy may be made in many forms of different grain sizes) and the purpose of the test will be critically important factors when considering the answer to your question. We can discuss “theoretical” limits to “detections”; but in UT (including and especially in TOFD) the response of the indication of concern over the background scatter noise from grain structure will be crucial. If you are expecting to RELIABLY “detect” flaws smaller than the grain size you will probably not be successful. The lateral wave will cause you problems at the lower end of thicknesses due to the dead zone (but I have seen shear wave TOFD used on 4mm wall in fine grained zirconium tubing). Thick sections (200-300mm) can also be tested by TOFD but accumulation of scatter increases with increasing soundpaths. In all cases the signal to noise ratio you can achieve will be the limiting factor for practical use of TOFD.

 

LoF vs. Slag when doing ToFD as per B31.3 in Piping

J. Mark Davis wrote:

LOF being a planar defect will tend to have a fast rise and fall time, and a short pulse duration. Slag is a volumetric defect and tends to have a slow rise and a long duration. Both defects can cause a beam redirection to the OD or the ID. Also, please realize that as with radiography, you can have several people look at a radiograph and make a slag or a LOF call, and sometimes not all will be in agreement. The same will hold true with UT and Phased Array. If the indication plots to the weld fusion line this probably is side wall lack of fusion. If the indication plots to the weld centerline, line this is probably Slag. Plus, you still analyze Rise and Fall and Pulse Duration.

 

Code Case 181

A lot people were searching for the actual code case 181 for ToFD. John O'Brien gave the URL to be as http://cstools.asme.org/csconnect/pdf/CommitteeFiles/15243.pdf on the page

 

ToFD working Procedure

Rohit Bafna of TCR Engineering Services wrote:

We perform ToFD Services in India and Saudi Arabia and have a two member team. The first team member does the scanning (we are doing ToFD projects as per API 650 appendix u, Code case 181 for piping as well as code case 2235-9) while the second person has a manual UT machine with him.  Prior to the start of any project we give out two documents:

- Procedure for examination

- ToFD operating guide for inspectors which illustrates the step by step machine operations. It also includes the timelines of work during the day. For example we prefer to do the scanning in the morning and reporting in the afternoon.

                                                                                      

I encourage others to update this posting/thread whenever they find any interesting article on ToFD. I hope over time, we can help other inspectors and fellow technicians learn and improve the usage of ToFD in the industry.

History of ASME B31

Author JohnBreen writes on eng-tips that that The ASME B31 Code for Pressure Piping includes specific “books” for various piping applications.  The Code is dynamic and the “sitting committees” work at keeping the Codes up to date with current standard industry practice – note, not “cutting edge”, not “trend setting”, not “latest and greatest" - rather current standard industry practice.   The B31 Codes are not the final word, only the latest word.

 

The history of the B31 Code is very interesting.  In 1926 the American Standards Associations, ASA (forerunner of ANSI) initiated project B31 to develop a pressure piping Code.  The resulting document, "American Tentative Standard Code for Pressure Piping, ASA B31.1 was issued in 1935.

 

During the long history of the B31 Codes various “book section” numbers were assigned for development.  Some of these documents were developed but not used as the work was pulled into another “book”.  Others of them were withdrawn when superseded by another document.  For completeness JohnBreen presented the following list of B31 “projects” and Codes:

 

B31.1 – Power Piping

B31.2 – Fuel Gas Piping, WITHDRAWN superseded by ANSI Z223.1

B31.3 – Process Piping, (formerly Chemical Plant and Petroleum Refinery Piping)

B31.4 – Liquid Hydrocarbon Transportation Piping (for example oil cross country pipelines)

B31.5 – Refrigeration Piping

B31.6 – Chemical Plant Piping, never issued as a separate document, folded into B31.3

B31.7 – Nuclear Power Piping, WITHDRAWN, superseded by ASME Code, Section III

B31.8 – Gas Transportation Piping (for example cross country gas pipelines)

B31.9 – Building Services Piping (for example office building hot water heating and air conditioning)

B31.10 – Cryogenic Piping, never issued as a separate document, folded into B31.3

B31.11 – Slurry Transportation Piping (for example cross country coal/water slurries)

Industrial troubleshooting using Radioisotopes

TCR (India, Kuwait, Saudi Arabia) in association with its Associates have upped its skills to now undertake intelligent pigging as well as other services to help conduct detailed quality inspections and assessments of pipelines/ reactors/ vessels/ process columns in refineries, petrochemicals, chemical, oil and gas industrial vertical.

 

TCR now undertakes:

• Blockage detection in underground pipelines

• Leakage detection/location in pipelines

• Gamma scanning of various process columns

• Residence time distribution analysis

 

Blockage detection in underground cross-country pipelines

TCR can undertake Blockage detection of almost all the major cross country pipelines using radiotracer pigs. Sealed source used is 5-10 mCi of 137Cs or 60Co. Associates of TCR have worked on the Mumbai - Pune 160 Km long pipeline, Kandla - Bhatinda pipeline, Vaizag - Vijaiwada 350 Km long pipeline and many other noteworthy projects.

 

Leakage detection/location in pipelines

Radiotracers are extensively used for locating leakages from underground pipelines and in industrial systems. The technique is cost effective. in the past, TCR Associates have accurately determined and located leaks of the order of 1 litre/hour from 10" dia cross country pipelines.

 

The principle of the Leak detector pig method is as follows:

1.  Leaky section fitted with pig launcher & receiver, radiotracer inlet & outlet

2.  Marker sources are placed on pipe in the dug pits at regular intervals

3.  Pipeline filled completely with diluted radiotracer (short-lived : mostly 82Br as ammonium bromide)

4.  A Data logger records the location of leak with respect to marker sources and downloads the same to a computer

5.  Location of leak is exactly identified with respect to location of marker sources

 

Gamma Scanning of various Process Columns

Gamma Column Scanning Technique is the only technique to view inside the column. Using this technique TCR, in conjunction with a RLA study, TCR can determine the health of a process column and help plants generate maximum output.

 

Residence Time Distribution Analysis (RTD)

In a chemical reaction of known kinetics, the extent of conversion will depend upon the time of reaction or MRT. The resulting distribution of residence times (RTD) governs the overall reaction. Most widely method used for visualization of RTD is ‘stimulus response technique.’ Interpretation RTD curve leads to determine dynamic hold-up of fluid flowing in the system.

 

A computer generated RTD curve gives information such as:

• Type of flow (plug flow, well mixed flow)

• Flow anomalies like, channeling, bye-passing, recirculation, presence of dead zones, parallel flow, etc.

 

TCR's associates have custom developed an RTD software that helps and assists in all analysis efforts.

Oil companies find shortage of engineers

USAtoday reports on an article titled, Oil companies scramble to find engineers.

Bustling oilfield activity and retiring baby boomers, among other factors, have petroleum outfits large and small trying to hire thousands of engineers, and experts say the trend is expected to extend into the next decade as worldwide energy demand grows.

"I've talked to quite a few of my peers, and we know we're in a good spot," Cornell University's Reasor said as she and Arsenault, of the Massachusetts Institute of Technology, took part in a week-long recruitment program sponsored by Royal Dutch Shell's U.S. arm. "It's nice to know we're needed."

Management consulting firm Oliver Wyman says roughly eight in 10 global oil and gas companies forecast a shortage of petroleum engineers through at least 2011. The American Petroleum Institute said U.S. energy companies will need at least another 5,000 engineers by decade's end.

Fossil fuels — despite efforts to find and market alternative fuels — will continue to be the world's primary energy source for the foreseeable future, making petroleum and other engineers vital for finding and extracting oil and natural gas from all around the world.

And demand is only going to grow.

The shortage of engineers has been caused in part by the upsurge in exploration and a wave of retirements from baby boomers who have spent 25 to 30 years on the job.
