A quick look at the advantages of using UT over X-Ray

Conventional X-Ray NDT methods have been used for inspection purposes for many decades. The method of using radiographs (RT) to get a picture of components that have been manufactured or damaged due to process has not come a very long way, in terms of technological advances, since the beginning. Many inspectors have cut their teeth on RT and used the method for many years are reluctant to give any other inspection technologies a chance to prove their usefulness. Most Digital RT systems still require conventional RT techniques and film shots to be performed before the digitization of the film or shot can occur. Ultrasonic testing has developed many new methods and has made several technological advances since it was first introduced as an inspection method. Different techniques such as advanced sizing methods, Time of Flight Diffraction, and Phased Arrays have given UT testing incredible abilities to outperform RT inspections on many different levels.

Ultrasonics vs. X-Ray

Safety: Safety is first and foremost on everyone's minds. RT inspections require technicians to be licensed by the state. They must carry RT safety cards and dosimeters to make sure they do not get overexposed to radiation they use. RT trucks carry large vats of dangerous chemicals that are necessary for the

development of the film. Inspection areas must be cordoned off or components removed from high traffic areas and placed far away from facilities in order to protect surrounding individuals from unnecessary radiation exposure. This can be difficult to do in small facilities or during Turnaround/Shut Down times when many different personnel are in the same area performing different tasks necessary for overall success. There are also different components in chemical plants and refining facilities that can be damaged or caused to malfunction when exposed to the high doses of radiation used by RT crews and equipment. Ultrasonic examinations use no radiation and no harmful chemicals. UT technicians and surrounding individuals and equipment are not in danger of harm from the UT equipment they use. Inspections can be performed right next to welding/fabricating personnel as well as other personnel and processes with no side-effects. The equipment is small, portable, and usually handled by one technician when good access to components is feasible. Quality: RT inspections produce visible images of the insides of components. RT is mostly used for the inspection of welds. RT has the ability to find almost all of the weld-related defects that can form during weld manufacture or through in-service process. It is difficult to see crack and crack-like defects using RT unless positioning of the camera is at the proper angle when the shot is made. Inspections are very problematic and the technician is unsure of the quality of the shot until the film is developed. Several things can go wrong during an RT shot. Not enough/too much exposure time, bad film, wrong camera position, bad chemicals cause image distortion, etc. If the shot is bad for any reason, it must be re-shot. This uses up valuable time and resources, especially if there are surrounding crews waiting to get back to work. Inspection times are long enough due to preparing the area, cordoning off and setting up barricades, placing film and camera into position, taking the shot, breaking down the equipment and area. UT testing results are immediate and accurate. Almost all of the weldrelated defects that can form during weld manufacture or through in-service process can be found using UT inspection. The user friendly equipment allows necessary changes to be made to the inspection to produce better results and

images. The technician knows immediately if changes need to be made to a calibration or if different techniques need to be used to enhance the inspection. There is little or no waiting time between inspections. Cracks and planar flaws and slag/porosity or volumetric defects are readily detected by UT inspections. Many advanced techniques like ToFD and Phased Array allow for digital images of the UT signals to be produced and analyzed on the spot. UT also allows for through wall sizing/depth of defects to be presented. RT does not provide through-wall location or depth of defects. Knowing exactly where the flaws is, the length of the flaw, and the depth of the flaw allows manufacturers and repair crews to pinpoint the location and repair the area without disturbing more of the component necessary. Breakdown: Lets look at a breakdown of the two inspection methods over several different areas:

1.0 Safety 2.0 Accuracy RT Inspection Radiation hazard. Provides location, length, though characterization of defect may be difficult. Require State certification. Two-man crews. UT Inspection No specific hazards. Provides location, length, depth, sizing, and characterization of defects. API certification available.

3.0 Personnel

4.0 Cost

From $800.00 to $1,800.00 per day depending on location. General RT training required. No Advanced training except for Digital RT.

From $600.00 to $2,200.00 per day depending on method and technique used. API certification and Advanced training for advanced methods available.

5.0 Training

6.0 Inspection Time

Slow setup time, from 4-12 shots per hour if in close proximity.

Short setup, Inspection times. Immediate results. Up to 20 welds per hour.

Conclusion: The comparisons between RT and UT Inspections show, in general, that UT is a safer, faster, more reliable inspection method. Costs between the two are comparable and depend largely on the methods used. Thick components such as heavy walled reactors and vessels can be inspected much easier and safer than using RT methods. While there are some applications where RT is a better suited inspection method, nearly every RT inspection can be done using UT methods.

INTRODUCTION : Phased Array technology is one of the latest INTRODUCTION advances in ultrasonics. It provides many useful tools for refining and chemical industry inspection purposes. A row of elements are excited in precise timing patterns to produce certain desired effects, such as ultrasonic beam steering or focusing the beam. This allows the user the ability to inspect certain portions or volumes of the weld using many different beam angles and focal laws. The result may be viewed as A-scan, Bscan, C-scan, or as a S-Scan (Sector scan) image. This technique is also used in a single axis scan motion, which makes it faster than conventional manual scanning.

Phased Arrays Phased Arrays

Phased Arrays use multiple elements in a single housing, excited at specific intervals to generate uniform wave fronts at specified angles. Any UT technique for flaw detection and sizing can be applied using phased array probes. Allows for high speed electronic scanning without moving parts. Inspections at multiple angles using a single, electronically controlled probe.

ADVANTAGES:: ADVANTAGES Phased Arrays are extremely useful when examining difficult geometries. The ability to focus the beam at different points allows for accurate detection and maximum resolution of defects. One transducer has the ability to perform several inspections at once. Phased Array inspections also include pipe and pressure vessel weld examinations, turbine disk blade root inspections, Raised face and Ring-Joint Flange inspections, as well as supplemental prove up techniques for HIC/SOHIC inspections. · Tandem scanning in one array for the inspection of vertical fusion faces in narrow gap welds. · Beam steering enables greater control and flexibility to inspect complex geometries such as shafts, threaded pins, railroad axle set, or complex geometry welds such as those found in multi-layered vessels. · Focusing the beam intensely is important when looking at highly stressed points of a component, e.g. turbine disks, weld root areas. · Multiple focus, varied angle, complex scans: automated pipeline inspections and aerospace components.

INTRODUCTION:: Time of Flight Diffraction (TOFD) was developed in the 1970's as a INTRODUCTION more accurate way to size planar flaws (cracks) for the nuclear industry. Advances in technology have made TOFD an extremely accurate and reliable defect detection tool, which can be used to gain data quickly with a positive result.

AIS Advance Integrity Solutions Inc.

PO Box 720 Danbury, TX 77534 Office 979-922-8230 FAX: 979-922-8231 www.advanceintegritysolutions.com

THE TECHNOLOGY:: Time of Flight Diffraction uses two ultrasonic transducers in a THE TECHNOLOGY pitch-catch method to introduce ultrasonic waves into the test piece for inspection. The transducers produce three distinct waves with different characteristics, paths and velocities.

Both longitudinal (compression) waves and shear waves are produced, which spread and give full volumetric coverage of the test piece. There are two different longitudinal waves that are introduced into the material, each with a different sound path. The first Lwave travels between the transducers just under the surface of the material and is called the "Lateral wave". The second is angled at the back wall and skips to the receiving transducer in a full-V path. Depending on the thickness of the material, different angles can be used to achieve full volumetric coverage. From these L-waves, shear waves are formed and propagate through the volume of the material. When defects are present, diffracted energy from the edges or tips are reflected and picked up by the receiving transducer. APPLICATIONS:: TOFD can be used on piping and vessel welds. It is a useful tool in APPLICATIONS finding defects during initial equipment production, as well as service induced defects that occur over time. Weld washout due to process, cracking in coke drum welds; general existing or new weld production defects as well as surface corrosion can be detected and measured using the TOFD technique. There is no need to raster the transducers, TOFD is preformed in a single parallel line scan which makes data collection fast. With good access without limitations, up to 300 linear feet of weld can be inspected a day using this technique and equipment.

INTRODUCTION : The AIS automated inspection system uses different components INTRODUCTION from several manufacturers to provide complete automated inspection capabilities. It applies the TOFD, Pulse Echo, Corrosion mapping, and Phased Array technology to nondestructively screen piping and vessels, such as those found in the refining and petrochemical industries. The user is provided with a true representation of the test material, which speeds the process of defect interpretation and reporting. All data is recorded in digital format and scans are exactly repeatable for long-term monitoring purposes.

THE TECHNOLOGY:: Automated Ultrasonic inspection uses conventional and THE TECHNOLOGY specialized transducers to introduce sound in the test materials. These transducers are mounted to automated robotic crawlers, which articulate to cover large areas of the vessel or piping surface. The data collected is then displayed in color in multiple A-Scan, B-Scan, CScan, and D-Scan images A-scan representation is the view in which the signal amplitude is shown as a vertical excursion from the horizontal sweep time trace. The B-scan and D-scan presentations are two-dimensional views of cross-sectional planes through the test object on

different axis. This imaging is helpful in distinguishing mid-wall inclusions such as laminations and blistering, from back-wall discontinuities like erosion and corrosion. The Cscan image is a two-dimensional plan view of the object. Indication of depth is color coded to provide the image with qualities, which resemble a topographical map viewed from the inspecting surface.

performed today. It provides reliable information about the remaining wall and ID geometries of equipment and piping to engineers and inspectors, who use the information to establish corrosion rates, equipment longevity, and maintenance and repair cycles. It also provides information on the material integrity, such as laminar defects and blistering, which may occur due to the migration of hydrogen through the material due to process. It is possible to scan up to 400 square feet of surface area per day with the automated system. All vessels and piping systems in the refining and petrochemical industry are subject to material degradation and automated corrosion scanning can help detect where problem areas exist or where they may possibly exist in the future. AUT scanning provides digital images, which can be regenerated or archived for future examination. AUT corrosion scans can be remapped to establish flaw extension over time, allowing Fitness for Service assessments.

PMI: Positive Material Identification

Inttroducttiion In roduc on

While engineers push the boundaries of material capacities to their limits in the design, traceability of proper material becomes ever more important. In addition to compatibility issues, several other reasons can exist for material specification including design, corrosion resistance, and compliance to codes and standards such as ASME Boiler and Pressure Vessel Code. Quality procedures and techniques are put in place to document and track materials as they are received and as they move through the production process, but what happened to those raw materials before they arrived at site? Each time raw material changes hands - from the mill to the supply house, from processing plants (e.g., pipe, tube and fittings) to subcontractors ­ the opportunity for error increases, resulting in questionable material quality. PMI gives the ability to check a component's material make-up and grade to verify proper material is being implemented for the project.

Positive Material Identification (PMI) provides alloy chemistry and grade ID information instantly using a handheld analyzer without having to move, alter, or damage the material. PMI is also used to ensure that the parent material in vessels and pipe material is composed of the correct composition (i.e., 304 or 316L) and once the component is welded that the correct filler material was used. PMI also ensures that the base material of piping and vessels meets the design specification. When repairs are made to existing vessels and piping systems, a PMI test can verify the material composition to ensure that the correct welding procedures and consumables have been selected for use.

While both the MT and PT methods detect surface and surface-breaking defects, MT is recommended for ferrous materials due to the need to establish a magnetic field in the component. MT/PT inspections can be used on almost every component found in chemical plant and refining operations. Both inspections are among the cheapest methods for testing in the NDT community today. Very mild training is needed to qualify these methods, however experience is recommended. Fast, reliable results performed at low costs helps the

owner/user and establish degradation and failure mechanisms and plan for mitigation and repair before catastrophic failure can occur. MT TECHNOLOGY:: MT TECHNOLOGY The presence of a surface or near surface flaw (void) in the material causes distortion in the magnetic flux through it, which in turn causes leakage of the magnetic fields at the flaw. This deformation of the magnetic field is not limited to the immediate locality of the defect but extends for a considerable distance; even through the surface and into the air if the magnetism is intense enough. Thus the size of the distortion is much larger than that of the defect and is made visible at the surface of the part by means of the tiny particles that are attracted to the leakage fields. PT TECHNOLOGY:: PT TECHNOLOGY Dye Penetrant inspection is based upon capillary action, where low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed, a developer is applied. The developer helps to draw penetrant out of the flaw where a visible indication becomes visible to the inspector. Inspection is performed under ultraviolet or white light, depending upon the type of dye used - fluorescent or nonfluorescent (visible). APPLICATIONS:: MT/PT inspections can be used on piping and vessel welds, forgings, APPLICATIONS castings, billets, and plates. It is a useful tool in finding defects during initial equipment production, as well as service induced defects that occur over time.
