Companies that design, fabricate, and operate pressure vessels and related equipment need to understand ASME code work. The American Society of Mechanical Engineers (ASME) established this group of comprehensive codes and standards to ensure these processes happen safely, reliably, and efficiently.
The ASME Boiler and Pressure Vessel Code (BPVC) was established in 1911. It remains a globally recognized standard governing how boilers and pressure vessels are designed, fabricated, inspected, and tested. Since its development, the BPVC has continued to evolve as needed to address the industry’s technological advancements and changing needs.
The BPVC’s structure comprises multiple sections. Each one is focused on different aspects of pressure equipment, such as:
- Section I: Rules for the construction of power boilers
- Section II: Materials specifications
- Section VIII: Rules for the construction of pressure vessels
- Section IX: Qualification standards for welding and brazing procedures
Strictly adhering to these codes ensures that pressure vessels are operated safely and maintain their structural integrity. There are severe consequences for any company that does not comply with these standards, including equipment failure, which can negatively impact workers and the environment.
ASME Code Pressure Vessel Design
There are different options for designing pressure vessels that comply with ASME standards. Here are some things to keep in mind.
Design Considerations
Engineers need to account for a variety of factors during the design phase, including internal and external temperature variations, pressures, and environmental influences. The BPVC provides clear instructions on how to account for these elements to enhance vessel durability and performance.
Material Selection
Choosing the right materials for pressure vessels is fundamental to their safety and longevity. Section II of the BPVC specifies requirements for both ferrous and non-ferrous materials that could be used in pressure vessel construction. To meet ASME standards, these materials must possess specific mechanical properties such as tensile strength, corrosion resistance, and temperature endurance.
Fabrication Techniques
Adhering to precise welding and forming techniques ensures quality in pressure vessel fabrication. The BPVC’s Section IX outlines the requirements for welding and brazing procedures. To comply with ASME standards, only certified professionals and approved welding methods can be used.
Inspection and Testing
Inspection and testing are necessary for verifying the integrity of pressure vessels. Section V mandates rigorous non-destructive examinations (NDE), including ultrasonic and radiographic testing, to detect any defects before the vessel is deployed for use.
