What is ASME B31.1

ASME B31.1, also known as the Power Piping Code, is a set of guidelines and requirements for the design, fabrication, installation, inspection, and testing of power piping systems. The code applies to piping systems that are used to transport steam, hot water, and other fluids in power plants, as well as other industrial and commercial facilities. It covers materials, design, fabrication, assembly, examination, inspection, testing, and certification requirements, as well as pressure testing, post-construction, and in-service inspection requirements.

The code covers a wide range of topics related to power piping, including materials, design, fabrication, assembly, examination, inspection, testing, and certification requirements. It covers both new construction and modifications to existing systems, and it includes specific requirements for different types of piping systems such as high-pressure, low-pressure, and high-temperature systems.

The code also includes specific requirements for various types of piping components, including valves, flanges, and fittings, as well as requirements for supports, anchors, and other piping accessories. It also includes guidelines for pressure testing, post-construction inspection, and in-service inspection to ensure that the piping system remains safe and reliable throughout its life.

Like ASME B31.3, ASME B31.1 is one of many codes and standards developed by the American Society of Mechanical Engineers (ASME) and it is part of the larger ASME B31 series of codes that cover various types of piping systems. The code is regularly updated to reflect the latest industry standards and technologies, and it is widely recognized as the industry standard for power piping in many countries around the world.

Difference Between ASME B31.3 and ASME B31.1

ASME B31.3 and ASME B31.1 are two codes developed by the American Society of Mechanical Engineers (ASME) that cover the design, fabrication, installation, inspection, and testing of piping systems. Both codes are part of the larger ASME B31 series of codes, which cover various types of piping systems.

The main difference between the two codes is the type of piping systems they cover. ASME B31.3, also known as the Process Piping Code, applies to piping systems used in the power, petrochemical, oil and gas, and other process industries. It covers the design, fabrication, installation, inspection, and testing of process piping systems. ASME B31.1, also known as the Power Piping Code, applies to piping systems that are used to transport steam, hot water, and other fluids in power plants, as well as other industrial and commercial facilities. It covers the design, fabrication, installation, inspection, and testing of power piping systems.

Both codes cover materials, design, fabrication, assembly, examination, inspection, testing, and certification requirements, as well as pressure testing, post-construction, and in-service inspection requirements. Both codes also include specific requirements for different types of piping systems such as high-pressure, low-pressure, and high-temperature systems.

In terms of materials, ASME B31.3 allows a wider range of materials compared to ASME B31.1. B31.3 also have a different design factor (Allowable stress) compared to B31.1. The B31.1 allowable stress is based on the material yield strength, while the B31.3 allowable stress is based on the material minimum tensile strength.

Both codes also include specific requirements for various types of piping components, including valves, flanges, and fittings, as well as requirements for supports, anchors, and other piping accessories. However, the specific requirements for these components may be different between the two codes.

Another difference between ASME B31.3 and ASME B31.1 is the level of detail provided in the codes. ASME B31.3 is considered to be more detailed and specific in its requirements, while ASME B31.1 is considered to be more general in nature. This is because the process piping systems covered by ASME B31.3 are more complex and require more detailed guidelines, while the power piping systems covered by ASME B31.1 are less complex and can be covered with more general guidelines.

ASME B31.3 covers a wider range of industries and applications, including petrochemical, oil and gas, and other process industries, while ASME B31.1 is mainly focused on power plants and other industrial and commercial facilities.

Additionally, ASME B31.3 includes specific requirements for pressure design, which are not found in ASME B31.1. These requirements are intended to ensure that the piping system is capable of withstanding the pressure and temperature conditions it will be subjected to during normal operation.

Another point of differentiation is that ASME B31.3 has a specific appendix for “Plastic Piping Systems” and “Nonmetallic materials” which are not found in B31.1.

It is important to note that compliance with both codes is mandatory for many piping systems in the US, and both codes are widely recognized as the standard for their respective types of piping systems in many other countries.

While both codes have similar requirements, they do have some differences in terms of materials, design factors, specific requirements for piping components, level of details, industries and applications and pressure design requirements. The choice of which code to follow will depend on the specific requirements and characteristics of the piping system being designed.

ASME B31.3 and ASME B31.1 are both codes developed by the American Society of Mechanical Engineers (ASME) that cover the design, fabrication, installation, inspection, and testing of piping systems. The main difference between the two codes is the type of piping systems they cover, with ASME B31.3 covering process piping systems and ASME B31.1 covering power piping systems. Both codes have similar requirements, but they may have some differences in terms of materials, design factors, and specific requirements for piping components.
