If you are searching for differences between ASME B31.1 (Power Piping) and ASME B31.3 (Process Piping), your search have been successful. As we have skilled professional piping engineers with vast experience in a variety of projects over more than 15 years, we decided to list the main differences between ASME B31.1 and ASME B31.3.
ASME B31.1 | ASME B31.3 |
|---|---|
ASME B31.3, Process Piping, is an American Society of Mechanical Engineers (ASME) standard that provides requirements for piping typically found in petroleum refineries, chemical, pharmaceutical, and other process plants. The standard covers materials, design, fabrication, assembly, erection, examination, inspection, and testing of piping. ASME B31.3 is a code that applies to the design, construction, fabrication, assembly, erection, examination, inspection, and testing of piping. It establishes requirements for materials, components, design, fabrication, assembly, erection, examination, inspection, and testing of piping that is used to transport fluids in process plants and other industrial facilities. The requirements of ASME B31.3 are organized into several sections, including: • General Requirements • Materials • Design • Fabrication • Assembly • Erection • Examination, Inspection, and Testing • Repairs and Alternations • Pressure Testing • Piping System Components • Nonmetallic Piping • Special Piping Components • Process Piping • Flanged Fittings • Threaded Fittings • Welded Fittings • Valves • Flexible Hose Connectors • Connectors • Supports • Special Piping Components • Nonmetallic Piping • Thermal Expansion • Expansion Joints • Identification and Marking • Quality Control • Quality Assurance • Inspection and Testing • Repairs and Alterations | ASME B31.1 is an American Society of Mechanical Engineers (ASME) standard that covers the requirements for the design, fabrication, installation, inspection, and testing of power piping systems. It is applicable to all piping systems operating at temperatures between -20 and 800°F (-29 and 427°C). The document outlines the requirements for materials, welding, and brazing, as well as requirements for pressure design and safety. It also outlines requirements for valve installation, pipe supports, and other safety-related topics. The standard also includes requirements for testing and inspection, as well as acceptance criteria for use in the field. ASME B31.1 is a code of practice for the design, fabrication, installation, inspection, testing and maintenance of power boilers. The Code covers rules for construction of power boilers, electric boilers, miniature boilers, and high temperature water boilers. The code also outlines requirements for safety valves, pressure relief devices, and other safety related items. In addition, ASME B31.1 provides requirements for materials, welding, non-destructive testing, and erection of power boilers. |
