Potential Air Leakage Location


When was the last time you inspected your system’s Check Valve(s)?

You may not even realize that your vacuum pump system has more than one check valve. These, however, are critical components. If your process isolation valve fails to operate during a system shut down the check valve upstream of the vacuum pump prevents air leakage into the main condenser. Continue reading

When was the last time you checked your Flow Control Orifice?


When was the last time you checked your Flow Control Orifice?

You may not even realize that your vacuum pump system has a flow control orifice.  This is, however, a critical part of your system, which controls the seal water flow to the vacuum pump.  This is a wear item.  It is recommended that flow control orifices be inspected every 12 months.

Specifying and Operating Steam Ejectors in Steel Degassing Applications

Steam ejectors have been used successfully to remove entrained gasses from molten metal for nearly forty years. The removal of hydrogen, oxygen and nitrogen by this method produces ‘clean’ steels with superior properties and a higher level of reliability without the addition of ferroalloys.

Steam ejectors are well suited to this application for many of the same reasons they have been used in other industrial processes. Ejectors have a low capital cost relative to other types of high vacuum producing equipment. Since they have no moving parts maintenance requirements are very low. An ejector system can be expected to operate indefinitely without downtime. Continue reading


A Texas plant wrote, "We would like to thank Nitech for its outstanding support and service through our recent turnaround initiatives. I would like to acknowledge John Aglitz (Chief Engineer) and Rich Rosser for their help expediting our replacement jets. Without their help, we could not have succeeded in meeting our timelines for this project completion. With sincere appreciation and thanks. BT"
