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 difference between ASME B16 & ASME B16.5 Flange
Yes - Cold bending is allowed by ASME B31.3. The requirements are detailed in Section 332. Generally the most difficult aspect of cold bending to ASME B31.3 standards is the requirement that the pipe not exceed 8% of the outside nominal diameter for internal pressure and 3% for external pressure. Thin wall tube and pipe generally require a mandrel bend.
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.
An ASME "U" stamp designates a vessel as a "pressure vessel" as defined and regulated by ASME codes

OSHA has the legal authority to enforce only those standards it issues. It has no authority to enforce ASME Standards, unless they have been incorporated by reference in a Standard issued by OSHA.
ASME having standards from A to Z .Y is the standard series for design series.

IS 2062 Grade 70 plates are primarily used in India and are equivalent to certain grades of ASTM A36 and A572 in terms of mechanical properties. However, they do not have a direct ASME equivalent since ASME standards cover specific applications and service conditions. For pressure vessel applications, ASME would typically require different materials, like SA-36 or SA-572, depending on the design requirements. It's essential to consult relevant codes and standards for specific applications.
"Society ASME." ASME = American Society of Mechanical Engineers The mark is to identify the approving standards body.
The ASME (American Society of Mechanical Engineers) standard that pertains to manholes is ASME B31.3, which covers the design and fabrication of piping systems, including manholes. For specific manhole designs and requirements, ASME also references standards like ASME B16.5 for flanges and ASME B16.47 for large diameter flanges. It's essential to consult the relevant sections of these standards for detailed specifications related to manholes in piping systems.
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.
ANSI = American National Standards Institute ASME - American Society of Mechanical Engineers ANSI is mainly a standards-keeping institution. ASME issues standards, but has other activities also (they publish a magazine, for instance).
