<p>Power piping is a term that refers to the pipes, tubes, fittings, valves, flanges, and other components that carry steam, water, gas, oil, or air in power plants, industrial facilities, and other applications. Power piping is subject to high pressures, temperatures, loads, vibrations, corrosion, erosion, and other factors that can affect its performance and safety. Therefore, it is essential to design, construct, inspect, test, operate, and maintain power piping systems according to recognized standards and best practices.</p>

<p>One of the most widely used and respected standards for power piping is ASME B31.1, also known as the Code for Pressure Piping. ASME stands for American Society of Mechanical Engineers, a professional organization that develops and publishes engineering codes and standards for various industries and disciplines. B31.1 is one of the codes under the B31 series that covers pressure piping for different applications.</p>
<p>ASME B31.1 was first published in 1935 as a tentative code for steam piping. Since then, it has been revised and updated regularly to reflect the latest advances in technology, materials, methods, and regulations. The current edition of ASME B31.1 was issued in 2020 and covers power piping for electric power generation stations; industrial institutional plants; geothermal heating systems; heating; ventilation; air conditioning; district heating; district cooling; cogeneration; solar power systems; fuel cells; waste heat recovery systems; hydrogen gas systems; compressed air systems; fire protection systems; steam tracing systems; auxiliary systems; and others.</p>
<p>The main purpose of ASME B31.1 is to provide minimum requirements for the design, materials, fabrication, erection, testing, inspection, examination, operation, and maintenance of power piping systems. By following these requirements, engineers, contractors, operators, inspectors, regulators, owners, and users can ensure that their power piping systems are safe, reliable, efficient, economical, and environmentally sound.</p>
<p>To obtain a copy of ASME B31.1-2020 edition, you can purchase it from the ASME website or from authorized distributors. The price of the code is $450 for non-members and $360 for members. You can also access the code online through subscription-based platforms such as Techstreet or IHS Markit.</p>
