Pressure Vessels & Heat Exchangers

Manufacturing, Evaluating, and Re-rating Pressure Vessels

Stress Engineering Services, Inc. is a certified ASME Boiler and Pressure Vessel Code (BPVC) Code Stamp holder. We design, manufacture, and install pressure vessels around the world, and can issue Certificates of Authorization for:

• ASME Section VIII, Division 1 Pressure Vessels (U)

• ASME Section VIII, Division 2 Pressure Vessels (U2)

• ASME Section VIII, Division 3 Pressure Vessels (U3)

From table-top to large-diameter systems and vacuum conditions to internal pressures over 50,000 psi – our engineers can design pressure vessels rated and sized to your specific operational requirements. These services are backed by our skilled staff of designers, process engineers, and materials engineers, with years of manufacturing and design experience and equipped with the latest engineering tools and software.

For decades we have been assisting clients with specifying optimal design conditions, identifying damage mechanisms, selecting proper materials, designing vessels and components to ASME Codes, developing engineering drawings, manufacturing of new vessels, and conducting design reviews. We work with you throughout all stages of vessel development, from the creation of the User Design Specification (UDS) through the final Manufacturer’s Design Report (MDR) that documents the engineering analysis.

Many of our pressure vessel engineers are active members on ASME code-writing committees. They also understand unique pressure vessel requirements and schedules.  We can either work with your engineers to develop the right vessel for you, or we can supply a turn-key vessel to meet your needs.

• Low or High Pressure Vessels
• Testing Vessels and Chambers
• R&D Test Vessels

• Food Processing Vessels
• Processing/Refining/Manufacturing Vessels
• Consumer Products Vessels

Evaluation and Assessment of New Vessels
Pressure vessel damage can come in many forms: local corrosion, local thin areas (LTA), general metal loss, cracks or crack-like flaws, pitting, creep, bulging, erosion, and environmental embrittlement to name a few. It is important to note that although significant damage may be present, the vessel may still be safe to operate. The API 579-1/ASME FFS-1 Fitness-for-Service standard is most commonly used to determine if a damaged vessel is suitable for continued operation. We specialize in these types of assessments and respond quickly.

Acquiring operational and vessel data is essential for developing a good understanding of the strength and condition of the vessel’s material. It is also vital to understand the source of the damage so that future damage can be predicted or prevented. At Stress Engineering Services, we regularly evaluate pressure vessels in varying degrees of distress, with conditions including:

  • Corrosion Mechanisms (pH, contents, temperatures, etc.)
  • Vibration (fluid flow-induced, mechanical, etc.)
  • Integrity Operating Windows (IOWs)
  • Piping Analysis and Piping Systems Programs
  • Structural Engineering

We are an R-Stamp holder for Vessel Repair and Alteration. We are familiar with working with Authorized Inspectors (AI) to successfully complete the R-Stamp process to ensure that your vessels operate safely for years to come.
