Hi Considering the table UW-16.1 General Note: "For fittings having a specified outside diameter not equal to the outside diameter of an equivalent standard NPS (DN) size, the NPS (DN) size chosen from the table shall be one having an equivalent outside diameter larger than the fitting’s outside...

Hi, Does a globe valve with a pneumatic actuator (like a PCV), controlled by a self-actuated pilot valve (upstream signal) and fail position open meets with requirements of UG-126(b)? Best regards Torsani

Hi, Is Min. End Wall thickness "G" from ASME B16.11 table 7 applied only for cap or also for coupling and half coupling? Torsani

Hi I need to determine the MAWP of a standard dimple jacket to be applied in vessels with diameter since 800mm until 4000mm. This dimple jacket is 17-1(a)(2) type (inflated). 1 - Should representative panel have a curvature according 17-5(a)(2)? 2 - Is enough only one representative panel with...

Hi I'm calculating a vessel with a internal coil. How can I apply UG-45 and UG-37 to coil penetration through the heads? Should I use the vessel internal pressure as coil externalç pressure? How? - Vessel's internal pressure: 6 bar. - Coil internal pressure: 79 bar. Thanks

Hi What are the reasons to consider UG-45(b)(1), (2), (3) and (4) only for nozzle neck thickness and not for manhole thickness?

Hi ASME VIII-1 UG-32 doesn't clarify what is the maximum apex angle of toriconical heads unde internal pressure. Until what angle can I use UG-32(h) rules? I think that the limit is 60 degree because UG-32(j). Am I right? After the limit can I calculate toriconical head as a flat head...

Hi Do ASME code show rules for design of internal coil (toroidal shell) subject to internal and external pressure? Thanks Torsani

Hi Do dimension (tmin) consider thicknesses of parts corroded in UW-16 or nominal thicknesses? Thanks Torsani

Hi Does ASME Code supply rules for pressure vessel design in acrylic? Tanks Torsani

Hi Why does some materials in ASME sec. II - Part D has the Allowable Stress varying with its thickness? Do allowable stress is different in the new vessel and in the corroded vessel? Thanks in advance. Torsani

Hi The ASME VIII-Div.1 code present, in appendix EE, tables for half-pipe's design limited in: 30<=D<=170 in., 3/16<=t<=2 in. and pipes with NPS = 2, 3 and 4. Can I use appendix EE for design half-pipe jackets with others dimensions, out of limits above? I no, how can I design others dimensions...

I need to design a relatively small atmospheric vessel (diameter = 2.500 mm)with torispherical heads, supported by legs attached in shell (in inferior tangent line). Do Have a code applicable for this vessel type? If not, What codes may I use ?
