Inspection dimensions

The measurements were earned out on rectangular slots in aluminium and mild steel inspected using two probes at several frequeneies. The size of the eoils are adapted to the dimensions of the slots which simulate rectangular defects. [Pg.142]

The analysis of the curves obtained in the thin-skin regime ean lead to a simple determination of slot length depending on the dimension of the probe chosen for the inspection. If the size of the probe (outer diameter) is smaller than the defect length we can notice 5 zones relative to the relationship between the position of the probe, the interaction of the induced eddy current and the slot, and the impedance change for the probe. [Pg.146]

The offered method has allowed essentially to simplify the X-ray apparatus main circuit, to reduce weight and dimensions of the apparatus, to increase sensitivity and reliability of the inspection and to ensure the apparatus control by a computer The main principle is based on the operation of the transformer controlled by magnetic commutation (TCMC). [Pg.430]

The requirements for an ultrasonic PC-board depend on the material and the dimensions of the component and on the type of inspection (manual or automatic inspection, with or without rmaging). [Pg.855]

The coin-tap test is a widely used teclinique on thin filament winded beams for detection of disbonded and delaminated areas. However, since the sensitivity of this teclinique depends not only on the operator but also on the thickness of the inspected component, the coin-tap testing technique is most sensitive to defects positioned near the surface of the laminate. Therefore, it was decided to constructed a new scaimer for automated ultrasonic inspection of filament winded beams. A complete test rig illustrated in figure 6 was constructed in order to reduce the scanning time. While the beam rotates the probe is moved from one end to the other of the beam. When the scarming is complete it is saved on diskette and can then be evaluated on a PC. The scanner is controlled by the P-scan system, which enables the results to be presented in three dimensions (Top, Side and End view). [Pg.983]

Using CD s streamlines the automatic comparison of data. Because of their large storage capacity and their reduced dimensions CD s provide a complete historical database for all steam generator tubes from a mobile inspection platform. [Pg.1024]

Laser-based profilometry is now being applied to a wide variety of both NDT and Quality Control gauging applications. In the world of NDT, the primary interest is in the details associated with surface topography or deformation of a particular component. Laser-based profilometry systems are commonly used to inspect surfaces for defects such as pitting, corrosion, deformation and cracking. Quality control gauges are used for absolute measurement of dimensions, such as the diameter and thickness of a given part. [Pg.1061]

Here m < 5, n = 8, p > 3. Choose D, V, i, k, and as the primary variables. By examining the 5x5 matrix associated with those variables, we can see that its determinant is not zero, so the rank of the matrix is m = 5 thus, p = 3. These variables are thus a possible basis set. The dimensions of the other three variables h, p, and Cp must be defined in terms of the primary variables. This can be done by inspection, although linear algebra can be used, too. [Pg.507]

For flanges of nonstandard dimensions or for sizes beyond the scope of the approved standards, design shall be in accordance with the requirements of the ASME Boiler and Pressure Vessel Code, Sec. T11, except that requirements for fabrication, assembly, inspection testing, and the pressure and temperature hmits for materials of the Piping Code are to prevail. Countermoment flanges of flat face or otherwise providing a reaction outside the bolt circle are permitted if... [Pg.985]

Shear strength is measured via a simple single overlap shear specimen of standard dimensions (Fig. 9). In contrast to its simple appearance, the forces in a thin-adherend shear specimen can be quite complex due to the inherent offset loading of the specimen and subsequent bending in the substrates. The single overlap shear test is anything but a pure shear test, but the configuration is easy to manufacture, simple to test and is firmly entrenched in the industry as a primary examination technique for materials qualifications, inspection and process control. [Pg.1147]

It must be pointed out that a Code stamp does not necessarily mean that the vessel is fabricated in accordance with critical nozzle dimensions or internal devices as required by the process. The Code inspector is only interested in those aspects that relate to the pressure-handling integrity of the vessel. The owner must do his own inspection to assure that nozzle locations are within tolerance, vessel internals are installed as designed, coatings are applied properly, etc. [Pg.334]

A better arrangement is shown in Figure 9-7. The dimensions are chosen so that the water injection pipe can be removed for inspection. [Pg.186]

In this case, the operations within a sequence are further defined according to various criteria such as whether they involve reception or transition of information, storage of information, manual control responses, inspections, and decisions. However, some other dimensions of an operation may require particular emphasis such as whether information is transmitted electronically, by external communication etc. A type of vertical axis can still be used to represent sequential order and if required this can incorporate the same timing information as temporal OSDs. [Pg.175]

The selection of column characteristics is determined by solvent resistance, the need to visually inspect the bed, the pressure rating of the system, and the dimensions [column inner diameter (i.d.) and length (L)] required from productivity considerations. Productivity considerations will vary if the requirement is based on the amount of information per unit time (analytical gel filtration) or the amount of substance per unit time (preparative gel filtration). [Pg.61]

Feedwater take-off. This will be from the bottom of the tank and preferably from the base with a weir pipe extending 50-100 mm up into the tank. If the take-off is from the side of the tank the bottom of the pipe bore must be a similar dimension up from the base. This allows sludge to remain in the tank, which should be inspected and cleaned as required. [Pg.359]

In planning the quality dimension, include specifications for the quality and types of materials to be used, the performance standards to be met, and the means of verifying quality such as testing and inspection. Two techniques facilitate planning for quality a work breakdown structure and project specifications. Both are described on the next few pages. [Pg.820]
