Daniel Steels Manufacturing LLC is a Houston-based fabrication company delivering engineering, procurement, manufacturing and field services for process piping, ASME pressure vessels, modular skid units, pipe racks and structural steel.
Section VIII Div. 1 pressure vessel fabrication.
Repairs and alterations, shop and field.
Welders qualified to ASME IX, B31.3, B31.1.
MTR records and PMI verification.
Most fabrication projects fail at the hand-offs: engineering that cannot be built, material that arrives late, or a shop that cannot support the field. Daniel Steels keeps engineering, procurement, fabrication and field support under one roof so the scope stays with the same team from bid to delivery.

QC dossier
06
Delivery & field support
Preparation for shipment, delivery and optional field installation support.
Final documentation
Yes. Engineering, procurement, manufacturing and field services are delivered by the same company, which reduces coordination gaps between design and the shop floor.
New pressure vessels are built to ASME Section VIII Division 1 under the ASME “U” Stamp. Piping follows ASME B31.3 or B31.1 as specified, and structural welding follows AWS D1.1 with welders qualified to ASME Section IX.
The shop is in Houston, Texas, and serves the Texas Gulf Coast and national projects. Field services can be mobilized to the plant site.
Isometrics, P&ID, vessel datasheets, material specifications or a scope narrative. If drawings are not final, a marked-up sketch is enough to start the conversation.
Send drawings, data sheets or isometrics and our estimating team will review the scope.
