Process reactor DIN

Fixed design pressures and temperatures Fixed dimensions, H/D ratio of the glass-lined inner vessel: same nozzle table, nozzle orientation, diameters; allows to find on the market, at different manufacturers new or reglassed equipment suitable for replacing a damaged reactor Standardized manufacturing tolerances Standard agitator support flange: allows interchangeability of drive systems and sealing systems Standard agitator shaft head: allowing for interchangeability, modernization, retrofit of agitators, regardless of the original manufacturer allows modernization of the sealing system in relation to the modern INTERSEAL dry9000® system, regardless of the original agitator manufacturer Standard nozzle necks and flanges: allowing for interchangeability between manufacturer components, such as manhole covers, baffles, internals, gaskets, clamps, split flanges, and so on In the frame of the mechanical standardization of the reactors, a standard for a minimum enamel quality of the so-called “chemical glass” was also defined: DIN EN ISO 28721-1 standard. The DIN 28721 standard defines the quality requirements and acceptance conditions of vitreous enamel for glass-lined equipment in process plants: Glassing quality, visual aspects, glass thickness, thickness variation Checks, such as the spark test, thickness measurement, magnetic particle test (if necessary) Enamel defects, acceptable, not acceptable, repair methods Final quality report The above are the minimum requirements that Pfaudler meets and regularly exceeds in manufacturing.
