Two of the most demanding process piping systems are steam and dump lines. Both operate under high pressures and temperatures, and multiphase flow is a frequent occurrence.
DRG is qualified and experienced and can help identify and solve the problems due to condensation and slug flow in these demanding systems.
One of the most hazardous forms of lines is the steam line. Working at high pressures and high temperatures, failures can have catastrophic effects.
The risk in steam lines is intensified by the potential formation of condensate, which results in two-phase conditions. Two-phase flow conditions can develop into slug flow, resulting in unbalanced loads on the piping systems, such that potential failure of the lines is a real possibility.
Generally, potential problems can be anticipated during the start-up of a high pressure steam line, due to condensation of the steam when the steam enters the cold pipe line. Moreover, during the plant stop, the steam that remains in the line during the stop may condensate.
In factories where dangerous chemicals or fluids are processed, it is common to have dump facilities to temporarily store dangerous processing liquids during an emergency situation. Dump lines are high performance lines, as they have to transport dangerous liquids under high pressures and multiphase flow conditions at high flow rates.
