Pressure Vessels & Storage Tanks (ASME Code)

Sweco Fab, Inc., designs and fabricates different kinds of pressure vessels per ASME Sec. VIII, Div. I, and welded steel tanks per API codes.

Sweco Fab has been fabricating multiple types of pressure vessels for the past 25 years in accordance with ASME Sec. VIII, Div 1 (Latest edition) and welded steel tanks per API 650 and 12F codes. Sweco Fab had fabricated vessels that fulfilled specifically to each customer’s requirements and will continue doing so in the future.

Sweco Fab can fabricate pressure vessels made out of Carbon Steel (including Low Temp CS A350 LF2), Stainless Steel (304/L or 316/L) and Cr-Mo Grade 5 (A387 Grade 5). The sizes ranges from 6″ OD to 110″ OD with vessel thickness up to 2″ thick. Our shop can accommodate vessel weights up to 40,000 lbs (20 tons) max.

We have certified welders, pipe-fitters and QC inspectors plus credible subcontractors to satisfy NDE requirements (X-ray, Dye Pen, PMI, Hardness and PWHT) per project specifications. Yearly training and refreshers are conducted in accordance to ISO 9001 Standard.

Sweco Fab has currently both ASME “U” Stamp and “R” Stamp authorized by the National Board of Boiler and Pressure Vessel Inspectors.

 



60" Carbon Steel Air Receiver Tank

Sweco Fab, Inc. recently fabricated an Air Receiver Tank for a Manufacturing Facility in Alabama. This 5,400 lbs tank measured 60″ 143″ tangent to tangent and was designed for 170 PSIG and 200 F. It was fabricated from SA516-70 carbon steel. The interior and exterior were painted with standard epoxy paint to provide an interior lining and exterior protection. The tank was hydro tested at 221 PSIG to ensure product quality.
