Overview - Process & Power Pipe Fabrication Shop

Pipe spool fabrication services are  at the roots of our company. At Didion Vessel, we have the know-how to design your power and process piping to ASME Sect 1, B31.1 or B31.3 (in addition to API specs). We hold the ASME “S” & “PP” stamps.

Our shop can provide you with the fabrication of pipe spools only. Or, we can furnish the piping as an add-on to your vessels for a turn-key approach. We also provide weld overlay services for your pipe, which is done on-site at our shop. Moreover, we build assembled skids, which include piping, pumps, valves, instruments, and wiring.

When to use ASME B31.1 (Power Piping) vs B31.3 (Process Piping)?

ASME prescribes B31.1 for process piping systems typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, and central and district heating and cooling systems. It also covers boiler-external piping for boilers.

Whereas, ASME B31.3 is for process piping most often found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals.

Whether it is the fabrication of process or power piping spools, rest assured our shop can handle your ASME or API code pipe.
