What internal pressures can be expected?
Products required to hold internal pressures must be substantially designed. Automotive Expansion tanks are the most widely used and will operate at 15 PSI in elevated temperature (95 degrees Centigrade) conditions. Pressure cleaning systems used in the Brewing industries operate at 60 PSI. The mechanical properties of the materials must be checked very carefully and products tested at suitable safety margins.
