AbstractAbstract
[en] The welding of pipes can be eliminated from many applications where steel pipes need to be joined. This is the claim made for the recently launched Morgrip flange. The Morgrip flange incorporates rings of spring-loaded ball bearings which bite into the pipes to be joined when the flange bolts are tightened. Independent tests have shown that the tear-shaped bites made by the ball bearings do not affect the integrity of the pipe, while the connection can be designed to be stronger than the pipe in axial tension, bending and torsion. The flange is also more compact than other types of mechanical coupling. (author)

AbstractAbstract
[en] Shipping packages 9975-02274 and 9975-04769 were examined in K-Area following the identification of a non-conforming condition; the axial gap between the drum flange and upper fiberboard assembly exceeded the maximum allowed value of 1 inch. The fiberboard in package 9975-02274 had slightly elevated moisture content, up to 19% wood moisture equivalent (WME). Other compliant packages have displayed similar moisture levels locally, but not as consistently throughout the entire fiberboard assembly. Evidence of mold was observed on the lower assembly, although it appeared relatively dormant. Relatively little compaction or physical degradation was observed in this package. Due to the mold, it is recommended that the fiberboard in this package not be re-used. The fiberboard in package 9975-04769 was relatively dry (7-10% WME) and showed no sign of compaction or physical degradation. Variations in the axial gap that have been measured on this package result from variations in the height of the upper and lower fiberboard assemblies, and their relative orientation to each other. The fiberboard in this package is physically sound and considered fit for continued use.

AbstractAbstract
[en] The effect of pre-strain on the stretch flange deformation limit of steel sheets was investigated by hole expansion tests under various pre-strain conditions. Pre-strain was given by stretch forming with a cylindrical punch. The strain ratio and amount of pre-strain were controlled by changing the blank shape and forming height. The hole expansion tests were carried out with a conical punch and cylindrical punch in order to clarify the effect of the strain gradient. The effect of the strain ratio of pre-strain on the stretch flange deformation limit can be expressed by equivalent strain. In the case of higher strain gradients, the stretch flange deformation limit increased with increasing pre-strain. However, at lower strain gradients, the stretch flange deformation limit was almost constant. These results suggest that the formability of the stretch flange deformation area given by pre-strain should be determined from not only the total equivalent strain but also the strain gradient and the amount of pre-strain expressed by equivalent strain.

AbstractAbstract
[en] A coaxial coupling device located in the beam pipe of the TESLA type superconducting cavities provides for better propagation of Higher Order Modes (HOMs) and their strong damping in appropriate HOM couplers. Additionally, it also provides efficient coupling for fundamental mode RF power into the superconducting cavity. The whole coupling device can be designed as a detachable system. If appropriately dimensioned, the magnetic field can be minimized to a negligible level at the flange position. This scheme, presented previously*, provides for several advantages: strong HOM damping, flangeable solution, exchangeability of the HOM damping device on a cavity, less complexity of the superconducting cavity, possible cost advantages. This contribution will describe the results of the first cryogenic test.

AbstractAbstract
[en] In order to reduce any danger to personnel during opening of the lid of a nuclear reactor, it is proposed to provide a screw fastening device, which eases the fastening and unfastening of the lid nuts, and the unscrewing and screwing up of the screwed bolts and their fastening and removal. It is provided that bolt supports are arranged on the support ring, which is supported on the lid flange, which unload the bolts with respect to their weight. (UWI)

AbstractAbstract
[en] A review of current practices in designing the transverse reinforcement of concrete bridge slab supported by wide-flange prestressed-T girders is presented. Slabs are commonly assumed to be supported continuously at the center points of girders, neglecting the effect of the girder flange stiffness. The design in this manner may produce conservative transverse reinforcement of the slab. As alternative a newly constructed bridge deck is chosen as a case study where the design based on this conservative assumption is compared with that considering the girder flange length, thickness and rigidity. The results of these two designs are compared. It is found that the amount of transverse reinforcement of the concrete slab obtained from the conventional design is considerably larger than that considering the girder flange stiffness. This promising finding warrants further investigation of the latter approach focusing on the effect of girder flanges in taking bridge loading in the transverse direction. (paper)
