Avoid Water Hammer Problems in High-Pressure Hydraulic Systems

Aug 06,  · Water hammer, high-velocity fluid flow and contaminated hydraulic media are among the worst enemies of high-pressure hydraulic systems. Water hammer, in particular, can be very destructive in high-pressure descaling applications. At steel mills, persistent water hammer in high-pressure piping systems often leads to burst pipes, cracked welds

Feature Report: The Number One Problem in a Steam System

Apr 15,  · (Page 1) Water hammer — a high-pressure surge or wave created by the kinetic energy of the moving liquid — is not only a system issue, but primarily a safety concern. Understanding the nature and severity of water hammer in a steam-and-condensate system will allow prevention of its destructive forces. A better understanding will also help with the introduction of preventative measures into

Supply Chain Modeling: What Does the Future Hold

The simulation allows companies to run the events through a model almost as though they were happening. Sometimes the simulation displays a 2D or 3D image that enables users to observe waiting lines, moving equipment, and congestion in real time—all before the facility has even been built. It is like watching a movie before it has been released.
