What are ASME Code Cases and how do I get one? This article addresses the who, what, where, why, when and how of the ASME Boiler & Pressure Vessel Code (B&PVC) code cases relative to valves and other pressure equipment. The article will also review the code cases that are in-process or issued regarding powder metallurgy parts.
To understand the content and use of a code case, we must first discuss what a standard is: a set of technical definitions and guidelines. So, a code is a standard adopted by a government (that has the force of law) or a standard required by contract. The ASME B&PVC is called “code” for a variety of reasons, but some have joked that it is because it is very difficult to decipher the process.
