Pressure piping, fabricated in accordance with ASME B31.3 or B31.1, can be supplied as a skid mounted system complete with pumps, valves and other miscellaneous components, or shipped as loose pipe spools.  Welding is normally done via GTAW (root pass) and GMAW/FCAW (cover passes).  Below are photos of some of the pressure piping projects completed.
