Experience from the field…
Since 1998 leaks have repeatedly been detected in 304L stainless steel bellows in a ‘contaminated’ process steam system at one of the chemical plants on the Chemelot Site. Investigations revealed that while the outside of the bellows were corrosion-free the inside exhibited severe corrosion. The challenge: to determine whether the corrosion was due to design of the bellow or the operating conditions.
Metallurgical selection for piping in the process industry
Many industrial accepted standards for pressure design address all aspects of piping design for
chemical plants and refineries; none discuss all of the considerations for metallurgical selection. These code standards do list materials that are acceptable for use in chemical plants and refineries.This paper discusses some but not all of the resources that a designer can reference in properly selecting materials for an application.
Burgundian beer: Brasserie de Vézelay
The Burgundy in France is better known for its wine than for its beer. The slopes leading up to the medieval hilltop city of Vézelay are clad with vines, and the area provides many opportunities for wine-tasting. However, there is plenty of room for brewers offering pure organic beer, which is why Marc Neyret set up his Brasserie de Vézelay in the village of Saint Père, near Vézelay.
