- STIRRED REACTORS
The De Dietrich Process Systems group designs, manufactures and markets solutions based on equipment that uses enameled steel, stainless steel, special alloys and borosilicate glass technologies. The group operates globally, with entities located in more than fifteen countries, making it possible to respond ideally to all of its customers. Uses of enamel Enamel is particularly used for highly corrosive applications, but also for neutrality and ease of cleaning needs. De Dietrich enamel is resistant to almost all acids, regardless of concentration. In addition, its low roughness gives it ideal properties for simplified cleaning and its composition free of toxic materials prevents any pollution from the coating to the products. Therefore, enameled equipment is ideal for use in the field of chemistry, plant chemistry and the pharmaceutical field. Chemists have traditionally used glass equipment for their experiments. However, due to the fragility of glass and technological limitations, manufacturing large glass equipment is impossible. The solution to this problem lies in the use of a metal-glass composite material, where the metal provides its mechanical robustness while the glass retains its distinctive properties. From the end of the 19th century, De Dietrich began producing enameled cast iron equipment to meet the needs of the emerging chemical industry. Today, chemical equipment is generally enameled with low carbon steels or austenitic stainless steels, allowing their use at very low temperatures, down to -100°C and beyond. Design, manufacturing and installation of enameled steel equipment and systems intended for the chemical and pharmaceutical industries. Our specificities : « Since its creation in 1684, the company has continued to evolve to become a world leader in the design and manufacture of enameled steel equipment and accessories for the chemical and pharmaceutical industries. »
Presentation
BASIC POSTULATE
RANGE OF EQUIPMENT
Our job
• De Dietrich enamel is designed according to a specific recipe with the main criteria being chemical resistance (acids and bases), but also mechanical resistance (impact, abrasion, thermal shock). For example, in a concentrated hydrochloric acid medium at 160°C, enamel loses less than 1/10 of a millimeter per year (in permanent contact 24 hours a day, 365 days a year). Bare steel would resist no more than 30 to 35 minutes under the same conditions.
• The enamel used on De Dietrich equipment is manufactured directly on the Dietrich site, thus guaranteeing optimal quality throughout the world.
• The enamel thicknesses follow a very precise standard (28138) which imposes a thickness varying from 1 to 2.2mm.
• The equipment is subject to the PED (Pressure Equipment Directive) and is therefore designed to withstand a wide temperature range (-25°C to 200°C) and severe service conditions (-1 to 6 bar). Steel thicknesses vary depending on the pressure required during chemists’ and pharmacists’ processes.
