A multi-effect distilled water machine is generally not classified as a pressure vessel as a whole, but its internal pressure-bearing parts, such as steam heating chambers, condenser shells, and connecting flanges, must still be designed, manufactured, and inspected according to relevant standards. Unlike reverse osmosis water purification equipment, a multi-effect distilled water machine is a thermal distillation device. It produces high-purity distilled water mainly through multi-effect evaporation and condensation, rather than by pumping water through membranes to reduce TDS.
In pharmaceutical, electronics, and other industries, multi-effect distilled water machines need to operate stably over long periods. The sealing performance, dimensional accuracy, and material selection of pressure-bearing parts such as steam heating chambers and condensers directly affect equipment safety and product water quality. Hansheng Automation can custom-machine heating chamber flanges, tube sheets, sealing rings, condenser end covers, and non-standard connection parts according to customer-provided drawings. We support single-piece and small-batch precision machining, helping users meet maintenance and modification requirements while ensuring the reliability of pressure boundaries.
