For small bore (3/8", 1/2", 3/4") steam service, running pipe with all of it's fitting requirements has become "the old way" of doing things. The new way of running small bore steam pipe is to run steam tubing that is preinsulated.
The beauty of preinsulated steam tubing is its ease of installation; not to mention that you can color code your steam pressures by choosing a wide variety of colors.
The practicality is impressive. There are less fittings required; thus less leak points...less time to install...and less contamination potential from thread sealant materials migrating into the steam space.
