ASME (American Society of Mechanical Engineers) standards for piping encompass various aspects crucial for designing, constructing, inspecting, and maintaining piping systems across industries. Here's a summarized overview:

1. ASME B31 Series: These are a set of codes that cover specific types of piping systems such as B31.1 (Power Piping), B31.3 (Process Piping), B31.4 (Pipeline Transportation Systems for Liquids and Slurries), B31.5 (Refrigeration Piping), B31.8 (Gas Transmission and Distribution Piping Systems), among others.
2. ASME B16 Series: This series covers standards for pipe flanges, fittings, valves, and gaskets used in piping systems. For example, B16.5 focuses on flanges and flanged fittings, while B16.11 deals with forged fittings.
3. ASME BPVC (Boiler and Pressure Vessel Code): This code provides standards for the design, fabrication, and inspection of boilers, pressure vessels, and nuclear power plant components. It includes various sections such as Section I (Power Boilers), Section II (Materials), Section III (Nuclear Components), Section VIII (Pressure Vessels), and more.
4. ASME Section II Materials: It outlines specifications and properties of various materials used in piping construction, including ferrous and non-ferrous materials, allowing engineers to select appropriate materials based on the intended application.
5. ASME B36 Series: These standards cover the dimensions and tolerances of piping components, including pipes, tubes, and fittings, specifying sizes, wall thicknesses, and materials.
6. ASME Piping Codes and Standards: They establish guidelines for design, construction, inspection, and maintenance of piping systems to ensure safety, reliability, and efficiency.
7. Quality Assurance and Non-Destructive Examination (NDE): ASME standards also encompass requirements for quality control, inspection techniques (such as radiography, ultrasonic testing, etc.), and documentation to verify the integrity of piping systems.
