Using a combination of automatic (robotic), machine, and semi-automatic (GMAW) welding, Do It American MFG produces many different configurations of spool pieces and flanged nipples for natural gas utilities across the country. Our welding processes are qualified to Section IX of the ASME Boiler & Pressure Vessel Code to ensure compliance with federal code requirements.

The samples displayed on this page represent just a tiny fraction of the different configurations we currently manufacture. Send us your drawings and specifications and we can set up to produce the parts you need.
