Armstrong: Guidelines for Steam System Efficiency

This educational video covers basic considerations in the design, piping, and trapping of steam systems. Topics include correct sizing and installation of steam supply and condensate return lines; steam velocities in the system; proper steam trap installation; trap safety factors; the use of air vents, vacuum breakers and safety drains; and how non-condensables affect the performance and service life of heat exchanger equipment.

Armstrong: What is Steam?

Armstrong: What is Steam?

This is the basics-of-steam primer… the "Steam 101" short course on the principles of steam that leads to a thorough understanding of the concepts outlined in the many Armstrong training courses and materials. Both live action video and clear, simple animation are used to illustrate steam properties and behavior. Everyday demonstrations and a straight-forward style help make this an informative and entertaining video, whether used as an introduction or as a refresher.

Armstrong: The Causes and Effects of Water Hammer

Armstrong: The Causes and Effects of Water Hammer

Water hammer has the potential to rupture valves, pipes, and fittings. Condensate can collect on the bottom of steam lines, out of the flow path, so it requires some external means, like gravity for instance, to move it through the system. While damage is most often caused by repeated occurrences of water hammer, sometimes damage can be immediate and catastrophic, and sometimes harmful to employee safety.
