The ASME (American Society of Mechanical Engineers) provides different certifications and stamps for various aspects of engineering, including pressure vessels and boilers. The ASME U and R stamps specifically refer to different types of certifications related to pressure vessels. 1. ASME U Stamp: The ASME U stamp is a certification for pressure vessels. It indicates that the manufacturer has designed and fabricated the pressure vessel in accordance with the ASME Boiler and Pressure Vessel Code (BPVC) Section VIII Division 1, which outlines the requirements for the construction of pressure vessels. The U stamp signifies that the vessel has been designed, manufactured, inspected, and tested in compliance with the rigorous standards set forth by the ASME. 2. ASME R Stamp: The ASME R stamp, on the other hand, is a certification for repair and alteration of pressure vessels. It indicates that an organization is authorized to repair and alter pressure vessels in accordance with the National Board Inspection Code (NBIC), which provides guidelines for the inspection, repair, and alteration of pressure-retaining items, including pressure vessels. The R stamp signifies that the organization has demonstrated the necessary knowledge, capabilities, and quality control procedures to perform repairs and alterations on pressure vessels. In summary, the ASME U stamp is related to the design and fabrication of new pressure vessels, while the ASME R stamp is associated with the repair and alteration of existing pressure vessels.

How Internal Pressure Ratings Dictate Shell Thickness On ASME Pressure Vessels The American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) provides guidelines and standards for the design, construction, inspection, testing, and certification of pressure vessels. Internal pressure ratings play a crucial role in determining the shell thickness of ASME pressure vessels. The following is an overview of how internal pressure ratings dictate shell thickness: ASME Code Requirements: The ASME BPVC provides specific rules and formulas for determining the required shell thickness of pressure vessels based on various factors, including material properties, design conditions, and loading conditions. Basic Equation: The basic equation used to calculate the required shell thickness (t) for cylindrical vessels under internal pressure is derived from the formula for hoop stress (circumferential stress). The equation is as follows: P⋅D/(2⋅S)+t=C where: P is the internal design pressure D is the inside diameter of the vessel S is the allowable stress of the material at the design temperature, t is the required shell thickness, C is a corrosion allowance (an additional thickness to account for potential corrosion). Factor of Safety: The ASME Code incorporates a factor of safety to ensure that the pressure vessel can safely operate under various conditions. The factor of safety is typically applied to the material's yield strength to determine the allowable stress (S). Material Properties: The material properties, such as yield strength and tensile strength, are critical in determining the allowable stress. ASME provides specific tables and guidelines for different materials. Design Conditions: The design conditions include the internal pressure, external pressure (if applicable), temperature, and other factors that affect the vessel's integrity. These conditions are considered in the determination of the required thickness. Corrosion Allowance: A corrosion allowance is added to the calculated thickness to account for potential corrosion over the vessel's service life. The corrosion allowance is typically specified by the engineer and is added to the calculated thickness as a safety margin. Special Considerations: In some cases, additional considerations such as nozzle loads, attachments, and openings may require specific analyses and adjustments to the shell thickness. It's important to note that the ASME Code provides different equations for different geometries (e.g., cylindrical, spherical, and conical vessels) and considers various loading conditions. Engineers must follow these guidelines and perform the necessary calculations to ensure the pressure vessel's safety and compliance with applicable standards. Additionally, inspections and non-destructive testing may be required to verify the integrity of the vessel during its service life. #permix #mixers #mixing #asme #industrialmixers #pressurevessels #vacuum

ASME (The American Society of Mechanical Engineers) mandates that 6 months after the release of the 2023 BPV Code, implementation becomes mandatory (January 1st, 2024). Manufacturers are free to implement the Code earlier if they choose. Under the provisions of the Safety Codes Act, unless the Minister adopts it sooner or later or with limitations, the 2023 BPV Code automatically “comes into force on the first day of the month following the expiry of 12 months after the date on which the amendment or replacement is published.” Meaning it will be mandatory in Alberta on August 1st, 2024. The users of the ASME codes are responsible to properly use new code editions in accordance with the requirements of the Alberta Regulations and ASME code of construction. It shall be noted that code users may start using the new edition of the ASME BPV code in Alberta immediately upon the code publication if there is no Ministerial Order stating otherwise. If a Manufacturer constructs an ASME BPVC Section VIII, Div. 1 pressure vessel that will have an ASME stamp, the Manufacturer may opt to use either the 2021 or 2023 edition of Section VIII, Div. 1 between July 1st and December 31st, 2023. After January 1st, 2024, the Manufacturer of a pressure vessel that will have an ASME stamp must use the 2023 edition of Section VIII, Div. 1. Similarly, a Manufacturer constructing a pressure vessel under CSA B51 using the rules of Section VIII, Div. 1 will issue the Manufacturer Data Report in accordance with CSA B51. In this case, the Manufacturer may use either the 2021 or 2023 edition of Section VIII, Div. 1 in conjunction with CSA B51 until August 1st, 2024. After that date, the Manufacturers of pressure vessels may only use the 2023 edition of Section VIII, Div. 1 in conjunction with CSA B51.

* Overview of ASME PCC-2 - Repair of Pressure Equipment and Piping: https://lnkd.in/dcVaVyJQ ASME PCC-2, Repair of Pressure Equipment and Piping, is a standard developed by the American Society of Mechanical Engineers (ASME) and provides methods for repairing equipment and piping within the scope of ASME Pressure Technology Codes and Standards after it has been placed into service. These repair methods include relevant design, fabrication, examination, and testing practices and may be temporary or permanent, depending on the circumstances. The methods provided in this standard address the repair of components when repair is deemed necessary based on appropriate inspection and flaw assessment. These inspection and flaw evaluation methods are not covered in this document, but are covered in other post-construction codes and standards.

Which of the two important standards can be considered more precise and more practical - ASME or ISO? Both ASME (American Society of Mechanical Engineers) and ISO (International Organization for Standardization) are standards organizations that issue international standards widely used in industry. Which one is considered "more accurate" or "more practical" depends largely on the context and the specific industry in which they are applied. ### ASME: - **Focused on North America:** ASME standards are most commonly used in the United States and Canada, although they have been adopted in other countries as well. - **Detailing and Specialization:** ASME tends to be very detailed and specialized in areas such as mechanical engineering, design and manufacture of pressure equipment, piping, and other technical applications. - **Pressure Codes:** The ASME Codes are considered a benchmark in the design and manufacture of pressure vessels and boilers, providing highly detailed guidelines. ### ISO: - **Global appreciation:** ISO has a much more global applicability and is widely used in Europe and many other parts of the world. - **General Standardization:** ISO focuses on creating standards that are widely applicable and cover a broad spectrum of industries, including quality management, environment, health and safety, and technical standards. - **Flexibility:** ISO is often seen as more flexible, providing guidelines that can be adapted to the specific needs of different industries and countries. ### Conclusion: - **ASME can be considered more specific** in specific fields such as mechanical engineering and pressure equipment due to its high level of detail and specialization. - **ISO can be considered more practical** in terms of global applicability and flexibility, being widely recognized and used in various industries and regions. The choice between ASME and ISO therefore depends on the specific context of the application and the requirements of local or industry regulations.
