SSC test with 4 point bend fixture as per NACE TM 0177 as well as the ASTM G 39 Specification

The corrosion testing laboratory of TCR in India routinely performs SSCC test with 4 point bend fixture as per NACE TM 0177 as well as the ASTM G 39 Specification. The tests are conducted using a strain gauge to measure stress. The laboratory is accredited as per ISO 17025 specification. In the past, the lab has conducted tests under third party inspection of BV, LRS, TUV etc.

 

TCR has been carrying out Sulphide Stress Corrosion Cracking (SSC) test for the past 10 years with tensile specimen. At several occasions, the corrosion testing department at the material testing lab of TCR have tested as per 4 point bend test and C ring specimen also.   TRC has used 4 point bend specimen under Third Party inspection of BV for Chloride Stress Corrosion Test.

 

The specimen for 4 point bend test shall be a flat specimen of different sizes.  We have 3 type of fixtures ready for 4 point bend test.  These can accommodate following sizes:

a)            140 x 25 x 5mm

b)            106 x 15 x 2mm

c)            63 x 4.5 x 1.68mm

 

These samples are prepared in our own machine shop in Mumbai, India using milling and surface grinding machines.

 

The technicians at the lab at TCR note the strain required to produce desired stress by loading a sample in tensile to desired stress and note the strain.  This manner enables for validation of the strain measuring and loading arrangement.  All specimen are loaded to a particular deflection which will provide some strain.

 

TCR has a set of 9 fixtures of each type and therefore we can load up to 9 specimens of one type at a time.  If more are fixtures are needed, we can get more fixtures made at one week's notice.  We have capacity to accommodate up to 24 specimens in our set of 3 vessels. 

 

In case more than 24 number of specimens need to be tested, we can always add another couple of vessel and it would increase capacity up to 40 specimens at a time. In order to add more vessels, it will take us about 2 to 3 weeks notice and in the meantime, we can proceed with machining of samples so that we are ready with specimen by the time over additional fixtures and cells are ready.

61st Annual Technical Meeting - Indian Institute of Metals (IIM)

The Indian Institute of Metals (IIM), which is the largest professional organization for metallurgists in India with over 8000 members from R&D laboratories, academia and industries, is organizing a technical meet at Nehru Centre, Mumbai during November 13-16, 2007. This Annual Technical Meet is being organized under the Chairmanship of Dr. S. Banerjee, Director, Bhabha Atomic Research Centre (BARC), who is the current President of the IIM. On this occasion, there will be a special publication on “Stainless Steels”.

 

Mr. V.K. Bafna and Mr. Paresh Haribhakti of TCR Engineering Services, India are presenting a paper on, “Metallurgical Investigation of blister formation on Hydrocracker Reactors of Refinery”  at this technical meet.

 

The Hydrocracker Reactors represents amongst the critical component of the Refinery and Petrochemical industries both in terms of cost and operation point of view. The Reactor vessel used for the hydrogenation service are made from of low alloy steels having chromium and molybdenum being typical weld overlaid with stainless steels on the inner surface of the vessel in order to protect the low alloy steel against corrosive environments such H2S and other corrosion.

 

One of the Refineries in the Middle East country faced the problem of blister formation on the Six Hydrocracker Reactors. There were total 102 blisters  formed inside surface of the Reactor and were formed all over the reactors surface having the small bulging with diameter of about 1" to 3".

 

The Hydrocracker operates at 380-445OC temperature and 112-158 bars pressure during service. The feed for the Reactors are VGO residue and hydrogen which is received from hydrogen plant.

 

The Metallurgical root cause investigation was undertaken both at site with visual, in-situ Metallography, hardness and ultrasonic testing. Cut samples from the blister were removed and studied for detailed metallurgical analysis in the laboratory to find out the reason as well fitness for future service of the weld overlay.

 

The results of filed Metallography showed presence of martensite layer at the interface with Inter-granular cracking a typical signature of hydrogen de-bonding. The laboratory testing further establish the presence of hydrogen in the weld overlay samples with the help of simple tensile testing on both as received condition and after hydrogen removal heat treatment. For future fitness of these weld overlays extensive Metallography studies were undertaken to find out the mechanism of crack formation and role of harmful phases like sigma and carbides.   With the use of quantitative Metallography the % age of these phases were evaluated to judge the overall integrity of Reactors and valuable inputs were provided for repair weld of these Reactors.

      

The reason for de-bonding was identified due to accumulation of hydrogen at the interface between alloy steel and stainless steel weld overlay region. Under the operating temperature and pressure hydrogen diffusion through weld overlay is inevitable. Nevertheless, slow cooling of the Reactor would facilitate hydrogen removal during shutdown. While on other hand, fast cooling will retain diffused hydrogen. Also, it can cause de-bonding between base metal and weld overlay.   This was confirmed at the Refinery was attacked in the war and shutdown was not done as per the recommended practice. The trapped hydrogen in the reactor over the time period it migrated and got accumulated at the interface and created de-bonding.

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)
