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...
