The ASME B31 Series, published by the American Society of Mechanical Engineers (ASME), is a collection of crucial standards that establish mandatory requirements for the design, materials, fabrication, erection, examination, testing, inspection, operation, and maintenance of piping systems used in various industries. These standards play a vital role in ensuring the safety, reliability, and longevity of piping systems that transport fluids like water, steam, gas, oil, and refrigerants.
