DE DIETRICH® history The history of the de Dietrich family has been linked to that of France and of Europe for over three centuries. To this day, the company that bears the family name continues to play a major role in the economic life of Alsace. De Dietrich® is one of the oldest manufacturing companies in France. It is located in the Vosges Mountains in North-Eastern France, where, as early as in the 17th century the rich natural resources of Alsace were beginning to be tapped. The presence of iron-ore, forests and water power led to the building of blast-furnaces and forges. In 1684, Jean...

enamel DD3009 MECHANICAL PROPERTIES Enamel is a glass with its qualities but also its main weaknesses which are brittleness and low tensile strength. Since the resistance of glass to compression is well above its tensile strength, one of the solutions to improve the mechanical resistance is to put the glazed layer under compressive pre-stress. This is achieved during controlled cooling after each firing. During mechanical work (deformation, mechanical or thermal shock) the compressive stress must first be offset by an equivalent tensile before the glass could be put under dangerous tensile stress....

enamel DD3009 THERMAL PROPERTIES The large majority of equipment that we manufacture is designed with a system that enables the heating and cooling of their contents. As heat transfers may cause serious damage to the enamelled coating, the user should respect the limits described in this chapter, which take account both of the data in the ISO 28721-3: 2008 norm and our experience as a constructor of glass-lined equipment. Instructions devoted entirely to the thermal properties of the enamel are attached to the Maintenance Manual of our equipment and enamel leaflet to enable their installation...

enamel DD3009 CHEMICAL PROPERTIES RESISTANCE TO ACIDS Generally, DD 3009 glass has a high degree of resistance to acids whatever their concentration, up to relatively high temperatures. For most of the inorganic acids, the resistance of the glass passes through a minimum for a concentration of 20-30% weight, then increases with the acid concentration. For example, the 0.1 mm/year rate is found at 128°C in H2SO4 30% and at 180°C in H2SO4 60%. Exceptionally, in the case of phosphoric acid, the speed of attack increases with the concentration: 0.1 mm/year at 163°C for 10% concentration and at 112°C...

Corrosion values Reference norm Here the permissible temperature limits are lower than for acids. At pH = 13 (NaOH 0.1N) this maximum is 70°C. Therefore, it is important to be cautious when using hot alkalis. Temperature must be controlled, as an increase of 10°C doubles the rate of attack of the glass. Care must be taken for the introduction of alkalis into a vessel. Avoid the flow of alkalis along the warm vessel wall by using a dip pipe. Thermal shocks – Statiflux surface cracks Mechanical shocks Improvement against former glass: 80 % °C Sodium carbonate Ammonium hydroxide Sodium hydroxide...
