Section VIII Division 1 Calculations
Target turnaround time is 10-12 business days
The Calculations J Lowry LLC can provide are a comprehensive resource to ensure compliance with the ASME® code and to ensure that pressure vessels are designed and manufactured to meet the required safety standards. Need a P.E. Validation & Certification? No problem, we have you covered!
ASME® calculations, specified in Section VIII Division 1, are vital for ensuring pressure vessel design safety, reliability, and compliance with industry standards. They consider internal/external pressures, temperature, material properties, and load conditions to determine dimensions and design features necessary for withstanding operating conditions.

Section VIII Division 1 specifically addresses the rules for the design and fabrication of pressure vessels that operate at pressures exceeding 15 psi (pounds per square inch) and have a maximum allowable working pressure (MAWP) exceeding 300 psi.
Within Section VIII Division 1 Calculations section lies a critical part that outlines the methodology and formulas essential for designing pressure vessels. It encompasses various aspects, including:
- Determining allowable stresses for materials
- Calculating component thickness
- Assessing welded joint integrity
- Evaluating vessel structural stability under diverse operating conditions
Why choose us for your next project you ask? For MANY reliable reasons; The J Lowry, LLC team possesses a unique position in the industry, offering top-level consulting and design services backed by years of industry experience and expertise across the entire design and manufacturing process. Our capabilities include Engineering Design Capabilities, 3D modeling, Stress Analysis (FEA), and P.E. Validation & Certification. We strive to be the partner you can rely on day in and day out for all your pressure vessel and design needs.

Piping ISO'S
ASME® B31.1 Code for Power Piping
This standard applies to any piping system within the gas transport or distribution industry. The ASME® B31.1 Code was written for power piping systems, covering fuel gas and oil systems in the plant (downstream of the meters), central and district heating systems, in addition to the water and steam systems in power plants.
Here at J Lowry, LLC, we can get those Piping Calculations & DWGs that meet your industry needs. Give us a call or contact us here!
Skid / Skid Packaging
It’s a self-contained, modular unit that is mounted on a skid (a platform or frame) for easy transport and installation. A Skid refers to a skid-mounted unit or package designed and fabricated according to the standards and requirements of the ASME®. It is often used for industrial processes like pressure vessels, piping systems, and equipment.

Let Us Show You The Difference We Can Make
Our experience makes a difference and will help prevent the common difficulties when designing pressure vessels.
Need a Stress Analysis (FEA)
There are many factors to worry about in designing a vessel, but Code Compliance and predicting how a Vessel will behave under various physical conditions should not be one. With decades of hands-on industry experience and state-of-the-art design software, we can help trim the fat from any design so that you can rest assured that you are building the leanest and most cost-effective vessel possible.
