It's in the ID as you may found attached (on the OD as the thickness of the pipe is not constant, some misalignment occurs). With my small experience usually it's the opposite that happens and we just trim the pipe to match the ID of the flange and therefore remove the misalignment, but in this...

Thanks for your repley i will look into it

Hello again, First of all sorry for the very late answer and thank you for your replies, I have a 20'' API 5L Gr B seamless pipe sch 20 and an 20'' FLANGE WN #150 RF ASME B16.5 SCH-20 ASTM A105N. With many efforts from our fitters we could make the misalignment to a maximum of 1.5 mm (as per...

Greetings you all, I'm currently working in an oil and gas project and i faced a problem , i have a 20'' Flange that the inside dia is smaller to my 20'' pipe (about 2-3 mm smaller), in ASME B31.3 is stated trimming is permissible for pipe to pipe but doesn't mention flange to pipe situation...

Thank you for your kind reply !

Morning all, I've found myself greatly confused about welding positions in WPS as per ASME Sec IX. At first i thought that the same table for WPQ (QW-461.9) was also used for writing WPS, i.e : i work in the field of storage tanks so the main positions we use are 1G, 2G, 3G, 5F and 6G (SMAW and...

Thanks guys your help is much appreciated.

Hello guys, So i've got an issue with a project, we need to find an equivalent to a material from a french code which is TU37C, because it's unavailable in the market -we have only astm material-. I've done some researches and i've found out that likes of A106 Gr A, A192.. are equivalent but...

It is not the shell that is hard to draw but it's rather the radiography spots that are boring and repetitive especially when naming them one by one.

Here's a copy of the excel file i made. So i was asking my self if there's another way more efficent to make it? And byt the way is it correct ? The thickness of the plates for the tanks are like this : - Demineralized Water Tank : between 24 and 8 mm - Desalinated Water Tank : between 11 and...

Hello guys, I'm still a newbie in this field (junior engineer with only 2 months xp) and i've got a task to do the nde map for a new project of storage tanks, my colleague told me to refer to the API 650 para 8.1.2 to understand how to do it. At this point everything is good but there's...

Greetings to all, So there is this issue that i'm trying to deal with in a project for a tank storage and it's about calculating the amount of filler metal consumables needed for the project. I've done some searches and i found a=this formula : W = A * Rho * L * 1/E Where : W is the weld metal...

Such a good point you made here. Thank you i'm learning many here day by day

Thank you and your replies are very appreciated. So it's more an economic issue than technical.

I'm a junior engineer in this filed that don't have much experience so i thought that it would be mentioned in the code. Thank you for your answer so it depends on its state.
