Thank for the input SnTMan,
We have supplied (and have had inspected and apporoved) the lapjoint flanges as supplied by our sub-vendor (maaass flanges)
But there is no formal consensus on what is right. Maass flanges machines the raised face of 150 & 300lbs flanges to get lap-joint flanges and...
Dear All,
Is is allowed to make 150lbs and 300lbs lap jojnt flanges from 150lbs and 300lbs slip on flanges by simply remomving the raise face?
My flange sub-vendor is telling me that this is allowed, but why is it then that the ASME B16.5-2009 lists different tf thicknesses for slip on...
Hi there,
We are manufacturing a sample cylinder made from SS304.
Normally all our welding is SS316(L).
We therefore have approved WPS/PQR for the welds needed for this product in SS316(L).
Both SS316(L) and SS304 are P8.1 accroding to ASME IX.
Can I have my SS304 welds made by our...
We make small pressure vessels in stainless steel. We think we are excluded from U-stamps according to U-1(c)(2)(i), because all our vessels are smaller than the dimensions called here.
ABSA Canada disagree on this and said they we do need U- stamps on out vessels.
Has anyone experience with...
Hi,
My company sells SS316 valves (bought) which get welded to SS316L weld neck flanges which we manufature ourselves from bar-stock.
A client of ours questions our welding SS316 to SS316L.
This should have a higher risk of corrosion.
They suggest it is necassary to use SS316L/SS316L.
I think...
Dear all,
I am designing a pressure retaining cylinder made from two seperate pieces of Alloy 625. We are joining these two sections by welding.
Now I have become convinced that post weld heat treatment for this weld in not neccessary. (Suppliers datasheets of alloy 625 state that post weld...
Dear Sir/madam,
I have a question about welding to ASME IX and ASME VIII .
I'm currently desgning a pressure vessel.
Due to space restrictions I can't get around the following construction:
A fillet weld closing the cooling jacket overlaps a buttweld of a connecting pipe to the cooling...
Hello all,
I am currently engineering a sampling system with flanged joints.
I must follow standards AMSE B16.5 and ASME B31.3
I'm using studbolts(material A193 B8 cl.2)and spiral wound gaskets in the flange conections.
In B16.5 and B31.3 I found what to use in studbolts & nuts (and wat is...
