Piping systems must be able to tolerate variations in pressure caused by starting or stopping pumps, opening or closing valves, filling and draining, etc. Piping systems should be analyzed to quantify transient pressures. For many systems, it is helpful to use a numerical model to quantify transient pressures and determine if and what type of surge protection is needed.



TEC solves transient problems for consulting engineering firms, equipment manufacturers, governmental agencies and law firms.
