Standards for pressure piping systems laid down by the American Society of Mechanical Engineers (ASME) are an integral part of providing safety, reliability, and efficiency in the design, construction, and maintenance of piping systems utilized in many different industries. The ASME B31 Code series specifically sets forth rigorous and comprehensive standards that encompass the entire piping process related to pressure piping. Compliant with ASME standards, Riyaarth Overseas provides piping solutions for the most demanding of applications.
Important Aspects of ASME Standards in Pressure Piping Systems
Comprehensive Guidelines:
- The ASME B31 codes provide requirements for the materials, design, fabrication, inspection, and testing associated with pressure piping systems.
- They ensure piping systems for a variety of industrial applications can safely support the pressure and temperature that will be present.
Safety and Reliability:
- The standards strive to reduce risks of failure through allowable stress, design conditions, and inspections and testing.
- The codes are regularly updated to coincide with changes in technology and industry practices, which will serve to improve safety.
Versatile Applications:
- The codes can be used to cover the full range of industries, including oil and gas, chemical processing, power generation, and pharmaceuticals.
- They ensure piping systems are adequate for transporting fluids, typically including an array of chemicals or mixtures, steam, gas, and water, in a variety of conditions. These respective plumbing applications typically require operating under stringent safety practices to avoid accidents.
Typical ASME Standards for Pressure Piping
Standard | Description |
ASME B31.1 | Related to power piping systems, including piping systems for utilization in power plants. |
ASME B31.3 | Related to process piping in industries like petrochemicals and pharmaceuticals. |
ASME B31.4 | Related to pipeline transportation systems for liquid hydrocarbons. |
ASME B31.5 | Related to refrigeration piping and heat transfer components. |
ASME B31.8 | Related to gas transmission and distribution piping systems. |
Manufacture and Testing Procedures
Pipes manufactured to ASME standards, are gone through strict processing to demonstrate compliance:
- Material Source: The highest quality material is sourced based on the usage requirements of the respective ASME standard
- Fabrication Method: Pipes are fabricated using one of two methods: welding or seamless extrusion to yield a structurally defined unit, ensuring structural integrity.
- Heat Treatment: Heat treatment processes are used, if necessary, to enhance mechanical properties.
- Review Procedures: All used components will undergo non-destructive testing (NDT), hydrostatic tests, and other review procedures needed to demonstrate conformance to safety standards.
- Records Maintenance: Paperwork defining the times and parts recalled, test results, all visual checks, and review procedures needed to demonstrate conformance to ASME standards will be documented and recorded.
Common Applications
Oil & Gas industry:
- Used for transporting crude, natural gas, and refined products under high pressure in pipelines. It also helps to ensure environmental protection against leaks.
- ASME also helps design pipelines to withstand environmental conditions such as extreme weather and seismic events so that systems are not compromised.
- ASME piping standards also help enable the use of safety valves and emergency shutdown systems to reduce the chances of an accident.
Chemical Processing:
- Enables the safe handling of hazardous materials in chemical reactors and transfer lines while preventing corrosion and maintaining integrity in the plant.
- ASME standards help select materials that are resistant to chemical reactions that could jeopardize safety or efficiency at a plant.
- ASME standards also help implement leak detection systems to reduce the chance of environmental contamination.
Power Generation:
- Governs piping systems in a thermal power plant ensuring that the operation is safe during service. Piping in a power plant uses steam and water at high temperature and pressures; hence it is critical to the operation. ASME standards help ensure that piping systems are designed to resist thermal stress and fluctuations in pressure sustaining reliable operations.
- ASME standards also help support the use of alternative materials that withstand high temperature and corrosive service conditions.
Pharmaceuticals:
- Ensures that piping systems meet stringent hygiene and safety standards required in drug manufacturing. These standards prevent contamination and maintain product quality.
- ASME standards assist engineers and designers in creating piping systems that are hygienic and accessible for cleaning, which lowers downtime and complies with many regulatory bodies.
- It provides assurance in the selection of non-reactive materials used with pharmaceutical products.
Food Processing:
- Regulates piping systems within food production, as used within regulated ingredients transport to promote a sanitary transport process. Compliance with HAACP helps to promote food safety throughout the food production process.
- ASME standards create piping systems that prevent cross-contamination and integrate with cleaning agents during food processing.
- It also allows for sanitary piping practices used to minimize product contamination.
Available Sizes and Dimensions
ASME-compliant pipe is available for various pipe sizes.
Pipe Size (NPS) | Wall Thickness (Sch STD) | Wall Thickness (Sch XS) |
1/2″ | 0.083″ | 0.109″ |
1″ | 0.109″ | 0.147″ |
2″ | 0.154″ | 0.218″ |
