Oil & Gas Inspection

Fitness for service

Fitness-for-service assessments evaluate the structural integrity of components and their suitability for continuous service. an add any service you want or edit the ones that are already listed. The method can be used to support design, fabrication, operation, change of service and life extension.

PSM (process safety management system)
is an analytical tool focused on preventing releases of any substance defined as a "highly hazardous chemical" by the EPA(Environmental protection act)or OSHA. Process Safety Management (PSMS) refers to a set of interrelated approaches to managing hazards associated with the process industries and is intended to reduce the frequency and severity of incidents resulting from releases of chemicals and other energy sources (US OSHA 1999). These standards are composed of organizational and operational procedures, design guidance, audit programs, and a host of other methods.

Three Levels of a Fitness-For-Service Assessment:
Level 1
Level 1 assessments require the least amount of data and experience. This type of assessment usually uses tables and screening curves and requires few computations. This means the computations can be quite conservative, similar to design code calculations. This level of inspection tends to take less time than the other two.
Level 2
If a Level 1 assessment on a piece of equipment does not meet acceptance criteria, a Level 2 assessment can be performed. A Level 2 assessment requires significantly more involved computations to replace the simple, conservative computations that make up the Level 1 assessment. The benefit is that fewer conservative calculations may lead to a better outcome, but the computations are complex enough that FFS software is often required.
Level 3
Generally, Level 2 assessment criteria are met and the equipment can be returned to service. But, In severe cases, a Level 3 assessment may be required. Compared to the previous two levels, a Level 3 assessment requires more detailed data and a considerable amount of operational experience on the part of the inspector. Because of errors that can occur due to using the more advanced equipment Level 3 analysis are rarely conducted.
The factors that go into selecting a level of FFS include the quantity of data available with which to perform an evaluation, the quality of that data, and the degree of significance of the analysis to equipment operations.

What is the meaning of standard? something established by authority, custom, or general consent as a model, example, or point of reference. the standard of the reasonable person. : something established by authority as a rule for the measure of quantity, weight, extent, value, or quality

Material classification: Another use of ASTM grade designators is found in pipe, tube, and forging products, * where the first letter (P) refers to pipe .Example: (A335 Grade P22). * (T) refers to tube. Example:(A213M Grade T22) * (TP) may refer to tube or pipe. Example:(A312 Grade TP304) * (F) refers to forging. Example:(A 336 Class F22) Grade, Type, and Class in material classification: 1- Grade is used to describe chemical composition 2- Type is used to define the deoxidation practice 3- Class is used to indicate other characteristics such as strength level or surface finish.

Advanced NDTs for Inspection of Catalyst Tubes of Reformer Furnace: * the determination of the serviceability of these tubes beyond their design life of 100,000 operating hours is of vital importance. A range of NDTs are presently available which provides the opportunity to improve the reliable service life of reformer tubes. * NDE assessment using : 1- Wall Thickness Measurement (apparent decrease in wall thickness with creep). 2- Replication (final stages of creep damage; i.e., macro-cracking). 3- Radiography (final stages of creep damage; i.e., macro-cracking). 4-Eddy Current Testing (responds to chromium migration due to overheating and conductivity changes). 5- Ultrasonic Testing (responds to attenuation and scattering).

Hydrogen attack/ fissuring: Steels exposed to high temperature high pressure hydrogen for days or months lose its strength and ductility suddenly. This type of damage is called hydrogen attack. Hydrogen attack is irreversible damage and occurs at high temperature. In hydrogen attack of steel, absorbed hydrogen reacts internally with carbides to produce methane bubbles along grain boundaries; these bubbles subsequently grow and merge to form fissures. Failures by hydrogen attack are characterized by decarburization and fissuring at grain boundaries or by bubbles in the metal matrix. This type of hydrogen damage is experienced in steels that are subjected to elevated temperature in chemical refinery plant equipments hydrogen and hydrogen-hydrocarbon streams at high pressure and high temperature. The severity of hydrogen attack depends on temperature, hydrogen partial pressure, stress level, exposure time and steel composition. Additions of chromium and Molybdenum to the steel composition improve the resistance to hydrogen attack.

Replication: Replica technique is one of the methods used for study of micro-structural changes and the extent and nature of damage/defects. The method being limited to study of the exposed surface, replica technique has comparatively limited used in the study of hydrogen related damage.

Eddy Current Testing: The technique relies on changes in electric circuit conditions; the circuit being the instrumentation, cables, sensing coil, and the item under test. As the mechanical properties of the test materials change, a change in overall circuit impedance occurs, which is displayed on an oscilloscope. By monitoring these changes, it can be inferred that creep damage is present, based on observation of the signal parameters in comparison to similar changes that occurred on known creep-damaged materials.
