Note: Only personnel suitably qualified and certified competent as per the relevant Act should perform activities consisting of internal and external inspections and pressure testing. During this operation the condition and calibration of the safety valves (In-Service only) as well as the applicable pressure gauges (New Manufacturing and In-service) are also checked. Safety valves (In-Service only) will be adjusted if required, either on-site or at an independent facility if so required. Problem areas are identified, and plant management is assisted to determine potential failure trends.
Tankage Inspection Services
API 653 tankage inspections are conducted examining the
tank's exterior and interior for signs of corrosion, damage, or structural
weaknesses using both visual and non-destructive testing methods. Proper
cleaning and preparation of the tank is crucial for a thorough inspection.
Regular API 653 inspections are necessary to ensure the continued safe
operation of storage tanks.
Key elements of an API 653 tankage inspection include:
▪ External visual inspection: Checking the tank's exterior for signs of corrosion, dents, cracks, leaks, or damage to the shell, bottom, roof, and appurtenances.
▪ Ultrasonic thickness surveys: Using ultrasonic testing to measure the remaining wall thickness of the tank shell, floor, roof, and nozzle areas to assess corrosion and determine if the tank still meets minimum thickness requirements.
▪ Vacuum box testing: Employing a vacuum box to detect leaks at weld joints on the tank floor and shell-to-bottom circumferential welds.
▪ Floor plating inspection: Thoroughly inspecting the tank floor plates for corrosion, pitting, and damage, often requiring cleaning to ensure proper visibility.
▪ Corrosion assessment of welded joints: Examining all welded joints for signs of corrosion, particularly at areas where different materials meet or where stress concentrations occur.
▪ Cathodic protection inspection: Assessing the integrity of the tank's cathodic protection system to ensure adequate corrosion mitigation.
▪ Internal inspection (if required): Depending on the tank's condition and access, an internal inspection may be conducted to examine the tank's interior for corrosion, sediment build-up, or other issues.
▪ Reporting: A detailed report documenting all inspection findings, including measurements, photographs, areas of concern, and recommendations for repairs or further actions.
Non-Destructive Testing (NDT) Consulting Services
Non-Destructive Testing (NDT) Consulting can be provided in order to assist Clients with the selection of the correct NDT type and the extent required, according to minimum code requirements.
▪ Magnetic Particle Examination (MT): Dry or wet fluorescent magnetic particle examinations are performed on ferromagnetic materials to detect surface and slight subsurface discontinuities such as cracks, seams, laps, voids, or flaws.
▪ Liquid Penetrant Testing (PT): Various types of liquid penetrant testing methods are utilized to detect material defects open to the surface or to detect open surface cracks. Red dye or fluorescent penetrants are utilized as well as various types of wet and dry developers. Fluorescent dye penetrant examinations are performed under black light conditions to ensure the highest detectability for very fine fatigue crack.
▪ Radiographic Testing (RT): Radiographic testing is utilized for the detection of internal defects in castings, welds or forgings by exposure to x-ray or gamma ray radiation. Defects are detected by differences in radiation absorption in the material as seen on a shadow graph displayed on photographic film or a fluorescent screen.
▪ Ultrasonic Testing (UT): In ultrasonic testing (UT), very short ultrasonic pulse-waves with centre frequencies ranging from 0.1-15 MHz and occasionally up to 50 MHz are launched into materials to detect internal flaws or to characterize materials. The technique is also commonly used to determine the thickness of the test object, for example, to monitor pipework corrosion.
▪ Hardness Testing (HT): Harness is defined as the “Resistance to Deformation”. When doing a harness test, the hardness tester applies a fixed load and the depth of penetration is measured by different means and converted to different units. More simply put, when using a fixed force (load) and a given indenter, the smaller the indentation, the harder the material. Indentation hardness value is obtained by measuring the depth or the area of the indentation using one of over 12 different test methods.
▪ Visual Testing (VT): Visual testing is the oldest and most common NDT technique “Visual inspection is the process of examination and evaluation of systems and components by use of human sensory systems aided only by mechanical enhancements to sensory input such as magnifiers, dental picks, stethoscopes, and the like.
▪ Holiday Testing (Spark Test): Holiday test or a Continuity test is one of the non-destructive test methods applied on protective coatings to detect unacceptable discontinuities such as pinholes and voids. The test involves checking of an electric circuit to see if current flows to complete the electrical circuit.
▪ Thickness Gauging (WT): Ultrasonic thickness measurement (UTM) is a non-destructive testing method used to inspect the metal thickness of ship hulls, piping and structural steel. Thickness measuring is essential across many industries to monitor corrosion, erosion and damage.
▪ Vacuum Box Testing: Vacuum Box testing is used to detect leaks at weld joints on the tank floor and shell-to-bottom circumferential welds.
