Jan 02,2003 storage tanks Minimum Thickness of Nozzle Neck#0183;I will explain the case.Suppose I have a drain nozzle at bottom head of the vessel of 6 NPS.As per nozzle internal pressure calculation the required thickness is 5 mm including corrosion allowance and as per UG-45 the minimum required thickness for 6 pipe is 6.22+3 (C.A) = 9.22 mm.The table calls it nominal pipe wall thickness.However,there is no prohibition to using thicker that I know of.See 5.2.3.2IFRs,I was trying to see if it would be OK to use thinner pipes? For example ,following the table as a minimum thickness,it is required to use aThe nozzle neck thicknesses are not so much for pressure even at the tank bottom but a truly economical way to get metal there for corrosion,stresIFRs,what appears counter-intuitive to me is that if you consider that a manway of lets say 500NB can have a 6mm / 0.236 neck (Table5-4) but a 30A manway has no fluid motion within it,has no external piping loads and nor is it attached to anything other than the tank that might induce stresacknowledged IFRs,and points taken.It is the intention to ensure robust nozzle is installed (small cost compared to vessel) and preserve the tankA manway has no fluid motion within it,has no external piping loads and nor is it attached to anything other than the tank that might induce streIFRs,is similar required on roof nozzle necks?Fixed roof nozzles are supposed to use standard weight line pipe for necks ( figure 5.19 ).They are not give nearly the attention that shell nozzlminimum thickness for nozzle necksOct 09,2003API 650 Thickness Reinforcement Plate for Nozzles See more resultsNozzle minimum thickness.- AST Aboveground StorageSep 05,2018 storage tanks Minimum Thickness of Nozzle Neck#0183;Depends on the nozzle size.API 650 Table 5.6 a for SI units or 5.6b for USC units gives the required thickness for tanks built to API 650.If your are inspecting a 12C tanks,you need to refer to that standard for required thickness used for those tanks.Tank Basics API 650 Fabrication - LinkedIn SlideShareApr 27,2017 storage tanks Minimum Thickness of Nozzle Neck#0183;Hot Taps Nozzle size- storage tanks Minimum Thickness of Nozzle Neck#173;to- storage tanks Minimum Thickness of Nozzle Neck#173;shell thickness limita storage tanks Minimum Thickness of Nozzle Neckgt;ons Table 9- storage tanks Minimum Thickness of Nozzle Neck#173;1 New Nozzle Loca storage tanks Minimum Thickness of Nozzle Neckgt;on - storage tanks Minimum Thickness of Nozzle Neck#173; In tank shell below liquid level Not allowed if welding causes environmental cracking Procedure per API 2201 Qualied Operator Minimum of 4 UT readings at nozzle loca storage tanks Minimum Thickness of Nozzle Neckgt;on Nozzle thickness - storage tanks Minimum Thickness of Nozzle Neck#173; Pipe Extra Strong

My thinking was that again,no matter what the API 650 standard repads are sized to handle this ID-sized opening,and then of course any extra thickness in the nozzle neck that translates to lost shell/repad width,is replaced 1:1 with the nozzle neck material anyways (assuming materials of course).API 650 ABOVEGROUND STORAGE TANKS,Part I Code ABOVEGROUND STORAGE TANKS,Part I Instructor Javier Tirenti P storage tanks Minimum Thickness of Nozzle Neck#225;g.13 2.3) Other applicable codes When designing a storage tank,it is necessary to meet the requirements of the design code (in this case,API 650),and also with all those requirements of the codes involved in the process of the tank.Some of them are listed below:46 CFR storage tanks Minimum Thickness of Nozzle Neck#167; 182.440 - Independent fuel tanks.CFR US Law (a) Materials and construction.Independent fuel tanks must be designed and constructed as described in this paragraph (a).(1) The material used and the minimum thickness allowed must be as indicated in Table 1 to storage tanks Minimum Thickness of Nozzle Neck#167; 182.440(a)(1),except that other materials that provide equivalent safety may be approved for use under paragraph (a)(3) of this section.
