Abstract: This paper describes new hitherto unused procedures that combine hydraulic and explosive expanding to produce tube-to-tubesheet joints in tubular heat transfer equipment with thick tubesheets. This ...

Abstract: This paper describes some results of shear load testing of welded and hybrid expanded tube–to–tube-sheet joints. The construction consisted of strength welding SA-688-TP 304N tubes to SA350LF-2 ...

Abstract: This paper discusses factory and field pressure testing of tubular heat transfer equipment such as closed feedwater heaters, steam surface condensers, and power plant auxiliary heat exchangers ...

Abstract: This paper advocates correlating rolling torque or hydraulic expanding pressure with shear load strength instead of percent wall reduction as the criterion of expanding adequacy for thin-walled ...

Abstract: The Bellamy nomograph is applied to a triangle over southeastern Florida and adjacent waters to compute the horizontal divergence and convergence in the lower levels for the period June?August 1951. The general diurnal ...
