Plumbers, Pipe-fitters and Steam-fitters

 Plumbers are not Pipe-fitters.  Each has specific skill sets.

Steam Fitters...have specific skill sets that are NOT akin to Pipe Fitting and Plumbing.

POINT...if it's a STEAM job...don't hire any outfit that does not provide TENURED, SKILLED steam fitters.

Best Practices with steam fitting is not something to lay off on a jack of all trades.
