Yes, welds at the knuckle radius of a dish vessel are permissible according to ASME Section VIII, provided they meet the specified requirements for design, fabrication, and inspection. The design must account for the stresses in that area, and appropriate welding techniques should be employed to ensure joint integrity. Compliance with the relevant codes and standards, including any necessary post-weld heat treatment, is also essential. Always refer to the latest version of ASME codes for specific guidelines and requirements.

What is the difference between ASME U and U1 stamps?
The ASME U stamp designates an unfired pressure vessel of more than 35 gallons (4.68 cu. ft.) has been built to ASME Code specifications, under ASME Code section 8. A U-1 form must be filed and signed by the authorized inspector for each and every pressure vessel built. The ASME U2 stamp is for unfired pressure vessels not built to ASME section 8 div. 1 standards, but under the alternative rules, has been inspected and found to comply with acceptable construction methods. A U-1 form signed by an authorized inspector must be filed for each such vessel, along with a description of the methods of construction used. The ASME U3 stamp is for high pressure (over 600 psi?) unfired pressure vessels. The ASME UM stamp is for pressure vessels less than 35 gallons capacity.
When you need a signed ASME U1A Form?
A signed ASME U1A Form is required when a manufacturer produces pressure vessels that comply with the ASME Boiler and Pressure Vessel Code. This form certifies that the vessel has been constructed according to the applicable code requirements and includes details such as design, materials, and inspections. It is typically needed for regulatory compliance, ensuring safety and reliability in the operation of pressure vessels. Additionally, it may be required for documentation during project approvals or inspections by relevant authorities.

Minimum requirement for ASME U stamp?
The design should conform to ASME Sec VIII Div.1.
ASME U stamp?
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes
Define ASME U1A Form?
When a newly manufactured pressure vessel is to be certified from ASME AI (Authorized Inspector), the AI stamps a form called "ASME U1A Form" with signature certifying that the vessel fabrication has been done according to the rules laid down by ASME Section VIII.
Is U stamp is required on a tank made according to asme?
Yes, a U stamp is required on pressure vessels, including tanks, that are constructed in accordance with the ASME Boiler and Pressure Vessel Code. The U stamp indicates that the vessel has been designed, fabricated, and inspected to meet the rigorous standards set by ASME for safety and reliability. This certification is essential for compliance with regulatory requirements and for ensuring the vessel's integrity during operation.
What do you call a Pressure Vessel according to ASME?
According to the American Society of Mechanical Engineers (ASME), a pressure vessel is defined as a container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. These vessels are subject to specific design, construction, and inspection standards outlined in the ASME Boiler and Pressure Vessel Code (BPVC). Pressure vessels are typically classified based on their operating pressure, temperature, and the nature of the contained substance. Compliance with ASME standards ensures safety and reliability in their operation.

The ASME U3 stamp is for high pressure (over 600 psi?) unfired pressure vessels. The ASME UM stamp is for pressure vessels less than 35 gallons capacity.
What is Maximum Allowable Working Pressure Calculations?
The ASME Boiler and Pressure Vessel Code details all the various calculations necessary to determine the MAWP of any pressure vessel.
What is ASME code for shaft design?
The ASME (American Society of Mechanical Engineers) code for shaft design primarily falls under the ASME B31 series for piping and the ASME Y14.5 for dimensioning and tolerancing. While there isn't a specific ASME code exclusively for shaft design, relevant guidelines can be found in ASME B107 for tools and ASME B30 for cranes and lifting devices. Additionally, the principles of stress analysis, fatigue, and material selection are essential in the design process, often using methodologies outlined in the ASME Boiler and Pressure Vessel Code (BPVC). These codes ensure safety, reliability, and performance in mechanical design and applications.
When you need a signed ASME U1A Form?
A signed ASME U1A Form is required when a manufacturer produces pressure vessels that comply with the ASME Boiler and Pressure Vessel Code.

What is equivalent to ASME section - viii divsion -1 to Indian standards?
The equivalent of ASME Section VIII, Division 1 in Indian standards is the Indian Standard IS 2825, which governs the design and construction of pressure vessels. IS 2825 outlines the requirements for materials, design, fabrication, inspection, and testing of pressure vessels, similar to ASME VIII, Div 1. Additionally, it aligns with the general principles of the Boiler and Pressure Vessel Codes in India, ensuring safety and reliability in pressure vessel operations.
When was ASME created?
ASME was created in 1880.

What is difference between ASME B16 & ASME B16.5 Flange
What does asme section viii require?
ASME Section VIII of the ASME Boiler and Pressure Vessel Code sets the standards for the design, fabrication, inspection, and certification of pressure vessels. It is divided into three divisions: Division 1 focuses on pressure vessels operating at either internal or external pressure, Division 2 addresses higher design requirements for more critical applications, and Division 3 covers pressure vessels for high-pressure applications. Compliance with these standards ensures safety, reliability, and quality in pressure vessel construction and operation.
