Condensate tanks collect the liquid water that forms after steam releases its latent heat to a process or heat exchange application, hold it at controlled pressure and temperature, and return it to the boiler feedwater system. The type required, the applicable construction standard, and the fabrication certification needed all depend on whether the tank operates at atmospheric pressure or above 15 psig. Key Takeaways Condensate tanks fall into two categories: atmospheric vented tanks that hold condensate at near-ambient pressure, and

Equalization tanks buffer variations in flow rate, concentration, temperature, or pH in industrial process and wastewater systems, delivering a consistent, controllable stream to downstream equipment regardless of upstream variability. The vessel holds the incoming process stream long enough for fluctuations to average out before the fluid moves forward to treatment, reaction, or distribution equipment. Key Takeaways Equalization tank sizing is driven by the peak-to-average flow ratio of the incoming stream, the required hydraulic retention time, and the variability in concentration

Thermal storage testing standards cover three distinct categories: code-required fabrication testing, performance testing, and in-service inspection. All three must be defined before the fabrication scope is finalized, because gaps in any category create problems that are significantly more expensive to resolve during commissioning than during the design phase. Key Takeaways Thermal storage testing standards span three categories: code-required fabrication testing, performance testing that verifies stratification efficiency, and thermal storage tank inspection standards that govern evaluation across the vessel service life.

The primary hydro test required for ASME Section VIII pressure vessels is a hydrostatic pressure test at 1.3 times the maximum allowable working pressure (MAWP), conducted with the vessel fully water-filled and witnessed by a third-party Authorized Inspector. The test must be completed before the ASME U Stamp is applied and before the vessel is released for shipment. Key Takeaways ASME hydrostatic test requirements under Section VIII call for 1.3 times MAWP, water-filled, witnessed by the Authorized Inspector, held long
