Sub Arc Weld Examples

Call Us for a custom built carbon steel storage tank to your specifications. We build large carbon steel tanks up to 14 feet in diameter and 50,000 gallons.
 

We utilize a flanges bottom that allows for two full penetration fillet welds between the shell and bottom. Our process "cones" the top surface to a pitch of 7-10 degrees - Increasing rigidity and keeping the top free of resting water.

All bottom and shell seams are welded inside and outside. Exterior seam welds utilize our submerged arc welding process (SAW) - the SAW produces continuous, uniform, ductile, corrosion resistant, and deep penetrating weld.
