In the name of God

The following brief article aims to introduce the ASME standard to enthusiasts, trainees, and students in engineering fields in summary form.

It is hoped that it will be useful.

ASME stands for the American Society of Mechanical Engineers, which is the professional organization responsible for developing standards for the design, fabrication, and maintenance of mechanical systems. The standards provided by ASME encompass a wide range of topics, including pressure vessels, piping systems, boilers, valves, and many other aspects related to the field of mechanical engineering.

The most well-known standard issued by ASME is the ASME Boiler and Pressure Vessel Code (BPVC), which provides rules for the safe design and construction of pressure vessels and boilers.

ASME standards also find wide application in manufacturing, construction, and even in energy industries to ensure safety, reliability, and quality in engineering practices.

ASME (American Society of Mechanical Engineers) has developed a set of codes and standards that are used in various industries. Some of the most important ASME standards include:

1. **ASME Boiler and Pressure Vessel Code (BPVC)**: This code includes requirements for the design, fabrication, and maintenance of steam boilers and pressure equipment.

2. **ASME B31.1**: Code for the design and construction of power plant piping systems and related industries.

3. **ASME B31.3**: Code for the design and installation of chemical and petrochemical processing piping.

4. **ASME Section VIII**: Includes specific requirements for the design and construction of pressure vessels.

5. **ASME Section IX**: Includes requirements related to welding, electrode selection, and inspection of welds.

6. **ASME Y14.5**: A standard for geometric and dimensional specification in product design.

7. **ASME B36.10M and B36.19M**: Standards for steel and stainless-steel piping.

These codes and standards are used to ensure safety, quality, and performance in the design and fabrication of mechanical and industrial products and systems.

What is the ASME standard coding system and how can we recognize the content of a standard from its name?

The coding and naming system of ASME standards is designed to provide accurate information about the type of standard and its area of application. These codes typically consist of letters and numbers that refer to the categories and topics related to the standard.

Structure of ASME Standards Naming

1. Initial Letters: These letters usually indicate the specific area or topic of the standard. For example:

- B: Piping and equipment.

- Q: Quality.

- N: Inspection.

- PV: Pressure vessels and boilers.

2. Number: The number in the standard name usually refers to a specific category of requirements or technologies.

- For example, B31.3 refers to chemical processing piping.

3. Sections and Subcategories: Some standards have various sections that specifically address certain aspects. For example:

ASME Section VIII: addresses pressure vessels and may include subsections such as Division 1 and Division 2.

Examples of Naming

ASME BPVC (Boiler and Pressure Vessel Code): the code related to steam boilers and pressure equipment.

ASME B31.1 and ASME B31.3: codes related to power plant and petrochemical piping systems.

This coding system helps engineers, designers, and inspectors easily access standards related to specific areas and comply with safety and quality requirements.

List of ASME Standard Codes:

The largest segment of the ASME standard, in terms of size and the number of volunteer contributors and users, is the Boiler and Pressure Vessel Code (BPVC). This code provides rules for the design, fabrication, installation, inspection, maintenance, and use of steam boilers and pressure vessels and their nuclear components. It also includes standards for materials, welding and brazing methods, qualifications, non-destructive inspections, and nuclear inspections.

Today, all 12 sections of ASME are recognized under the title BPVC and are numbered as follows:

- ASME BPVC Section I: Rules for the construction of power boilers

- ASME BPVC Section II: Material specifications, including 4 parts: A (ferrous materials), B (non-ferrous materials), C (welding materials), and D (other types of materials)

- ASME BPVC Section III: Rules for nuclear power plants

- ASME BPVC Section IV: Standard for thermal boilers

- ASME BPVC Section V: Non-destructive testing (NDT)

- ASME BPVC Section VI: Standards for maintenance of thermal boilers

- ASME BPVC Section VII: Standards for maintenance of power boilers

- ASME BPVC Section VIII: Pressure vessels (includes 3 subsections)

- ASME BPVC Section IX: Qualification and procedures for welding and brazing

- ASME BPVC Section X: Fiber-reinforced plastic pressure vessels

- ASME BPVC Section XI: Rules for technical inspection in nuclear power plants

- ASME BPVC Section XII: Rules for the construction and continuous operation of transport containers

- ASME BPVC Code Cases: includes additional rules and standards for greater comprehensiveness regarding boilers and vessels.

In addition to these 12 sections, ASME has other committees that cover various technical areas:

- ASME B16: Dimensional standards for fittings, connections, and gaskets

- ASME B30: Standards for lifting and hoisting equipment

- ASME B31: Process and power piping standards

- ASME A17: Standards for elevators and escalators

- ASME BPE: Biotechnology equipment
