Every PSB project is backed by code-stamped fabrication, certified welding, and in-house engineering. These credentials are maintained across every project PSB delivers, regardless of scope or industry, and they reflect the same standards EPC procurement teams require during vendor pre-qualification. Certificate copies are available upon request to support that process.

ASME Code Stamps

PSB holds the full set of ASME code stamps required for pressure vessel and boiler fabrication.

U Stamp
Pressure Vessels (ASME Section VIII, Div. 1)

UM Stamp
Miniature Pressure Vessels

S Stamp
Power Boilers
(ASME Section I)

R Stamp
Repair and Alteration of Pressure Vessels and Boilers

Welding Qualifications

Every weld is performed by qualified welders and inspected by an on staff Certified Weld Inspector.

ASME Section IX certified welders

AWS D1.1 structural welding certified

Certified Weld Inspector (CWI) on site

Electrical Qualifications

PSB's in-house electrical engineering team designs and builds listed control panels to code.

UL, cUL listed (UL508A)

CSA

NEC electrical

Process Piping

PSB designs, fabricates, and tests process piping systems in full compliance with ASME B31.3 (the code standard required on virtually every oil and gas, chemical, and petrochemical EPC project. Compliance is not assumed.) It is documented through inspection and test plans on every project.

ASME B31.1, ASME B31.3 and ASME B31.12 Process Piping design, fabrication, and testing per code
Piping systems engineered in-house by PSB's process engineering team
Carbon and stainless steel fabrication under one roof
ASME Section IX certified welders on all pressure piping work
Certified Weld Inspector (CWI) on site for all code piping
Hydrostatic and pneumatic testing performed in-house before shipment
Segregated stainless work areas with dedicated tooling.
Material traceability maintained from mill certification to final assembly

Engineering

PSB's engineering capability is what separates it from a fabrication-only shop. Process and structural engineering are handled entirely in-house by Professional Engineers. This means PSB can own the full scope from initial design through shop-tested delivery, without subcontracting the engineering risk to a third party.

PE-certified Engineers on Staff — process and structural disciplines
PE-stamped Drawings —explicitly required by many EPC project specifications and jurisdictions. 
In-house Process Engineering — flow rates, gas composition, inlet and outlet conditions
In-house Structural Engineering — skid frames, lifting lugs, anchor bolt patterns, seismic qualifications
In-house Electrical Engineering — UL 508A listed control panels and instrumentation loops
Dedicated Project Management Team — assigned PM for every project from order through delivery

Federal Contracting

PSB Industries maintains an active SAM.gov registration and CAGE code and is eligible for award of federal contracts and subcontracts.
