Galvanneal (GA) is produced at ArcelorMittal galvanizing facilities in Canada and the USA on continuous lines by passing pre-heated continuous strip through a bath of molten zinc.In this case after zinc coating,the strip is passed through an annealing furnace which transforms the zinc into a zinc-iron alloy coating on the steel surface.Pressure Vessel - Fabrication ToleranceSep 02,2015 Galvanneal Fabrication Tolerances#0183;Very few fabrication tolerances are stated on ASME VIII Code.The rest (and they're quite a few) are stated,as Joey clearly said,on Engineering Standards issued by engineering companies or corporations that are users of pressure vessels (Esso,Dupont,Monsanto,Dow Chemical etc.etc.).I've got with me,since my days of erector engineer,the Pipe Fabrication Tolerance as per ASME B31.3 - Pipelines B31.3 does not list these tolerances in a manner that you're probably after.B31.3 has certain criteria on fabrication,but not such specific tolerances.You need to set these up yourself.You can use industry practices such as PIP PNSC0001 en PFI ES-03 as a good starting point.

Galvanneal is the main Paintgrip used in the duct fabrication industry taking the place of Phos Bond which used to be the only option many years ago.A40 Galvanneal is the most commonly used coating,while A60 is less popular because it tends to be too powdery when it sits unpainted too long.Galvanneal Fabrication Tolerances - protocaseStandard Tolerances For Galvanneal Usually,choosing material thickness is one of the first steps a designer takes when starting a project.We work with nominal thicknesses,so it's important to know the thickness tolerance on the material you chose,in order toGalvanneal Fabrication Tolerances - ProtocaseStandard Tolerances For Galvanneal Usually,choosing material thickness is one of the first steps a designer takes when starting a project.We work with nominal thicknesses,so it's important to know the thickness tolerance on the material you chose,in order to
