What type of information does Part D of the ASME BPVC provide?

Part D of the ASME Boiler and Pressure Vessel Code (BPVC) primarily provides tables for design stress values, tensile strength, yield strength, and other critical material properties. These tables are essential for engineers and inspectors as they rely on standardized values to make calculations and engineering decisions related to the design and integrity of pressure vessels and piping systems.

The information included in these tables allows for accurate analysis and assessment of material performance under various conditions, ensuring safety and compliance with regulatory standards. Understanding these material properties is fundamental when determining the suitability of specific materials for use in pressure vessels, as they directly impact design calculations and the overall reliability of the equipment under operational stresses.

The other topics, such as non-destructive testing methods, welding procedure specifications, and pressure relief device requirements, are covered in different parts of the BPVC, indicating that B is the correct answer in the context of what Part D specifically addresses.
