ASME B31.3
ASME B31.3 Process Piping Code requirements for process piping design and construction is an obstacle to the designer, manufacturer, fabricator, supplier, erector, examiner, inspector, and owner who want to provide a safe and economical piping system.
Scope
Rules for the Process Piping Code Section B31.3 have been developed considering piping typically found in petroleum refineries; chemical, pharmaceutical, textile, paper, semiconductor, and cryogenic plants; and related processing plants and terminals.
Content and Coverage
(a) This Code prescribes requirements for materials and components, design, fabrication, assembly, erection, examination, inspection, and testing of piping.
(b) This Code applies to piping for all fluids, including:
1. raw, intermediate, and finished chemicals;
2. petroleum products;
3. gas, steam, air, and water;
4. fluidized solids;
5. refrigerants; and
6. cryogenic fluids.
(c) See Fig. 300.1.1 for a diagram illustrating the application of B31.3 piping at equipment. The joint connecting piping to equipment is within the scope of B31.3.
