Expansion tank

STF surge tanks protect hydraulic networks against water hammer. Custom-designed under international standards, they are suitable for drinking, wastewater, and seawater systems, with full instrumentation and control integration. STF Filters' surge tanks are engineered to absorb the effects of water hammer in hydraulic networks, protecting pipelines and equipment from sudden pressure changes. Manufactured under AWWA and ASME standards, each unit is custom-sized based on hydraulic parameters such as flow rates, closure times, pipeline lengths, and maximum allowable pressures. Available in open and closed configurations, they feature automated control systems with regulating valves, pressure switches, compressors, and supervisory control units. Constructed in carbon steel with internal and external anti-corrosion coatings, or in stainless steel for aggressive water types (potable, wastewater, or seawater). Their robust design withstands severe operating conditions and adjustable volumes. Surge tanks can include advanced instrumentation, relief valves, automatic vents, and remote monitoring systems. Ideal for pumping stations, treatment plants, and pressurized water transport systems, STF surge tanks ensure reliable, long-lasting protection against hydraulic transients. Surge Tanks for Demanding Hydraulic Network Protection The STF surge tanks is designed to absorb overpressures caused by water hammer in pumping and pipeline systems. Its main function is to protect pipes, valves, and sensitive equipment from sudden pressure changes, extending their service life.
