What is difference between ASME B16 & ASME B16.5 Flange
BS Standard is a Specification for steel globe and globe stop and check valves (flanged and butt-welding ends) for the petroleum, petrochemical and allied industries the list below are standards that i wish help to you API 600 API 6D API 6A ASME B16.5 ASME B16.34
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.
The PN16 flange is equivalent to either the ASME 150 or 300. The PN is related to Nominal Pressure and the ASME is the standard for the American Society of Mechanical Engineers.
