Thanks XL83NL. Any references of companies (global or APAC region) who can do this kind of work?

Dear all, In one of our plants we have noticed internal preferential corrosion in the CS welds mainly due to wrong filler material used during the welding process. The driver for corrosion mechanism is wet CO2 gas. We are planning to replace the pipework with a suitable weld metallurgy and...

Thanks - any references of companies (global or APAC region) who can do such quantification of nozzle loads (stresses) using the techniques mentioned above (i.e. strain gauge, load cell, camera...)?

Peers, Are there any ways to measure nozzle loads (e.g. using load cells, strain gauges etc) on pipework or vessel to compare whether it is exceeding the allowable nozzle loads? From theoretical perspective I understand that we can do stress calc or FEA etc, but looking for some techniques /...

The Obturator - Not entirely sure about the explicit reference. However, this is the response I got from the supplier: "ASME BPVC UG-136 (b)(3) states that materials for “bodies, bonnets or yokes, and body-to-bonnet or body-to-yoke bolting shall meet all applicable requirements of Subsection...

Does the recent version (2019) of ASME VIII Div 1 change the minimum temperature of carbon steel cast valves A216 WCB, WCC from -30deg C to -8deg C. One of the US pressure relief valve supplier is stating that the code has changed so that the body / bonnet material of new valves with a design...

Thanks georgeverghese. Is there any calculation method or reference to work out tube velocity in such cases?

Looking for some guidance on max tube velocity calculation for wet saturated gas in air cooled exchanger. The exchanger is designed as per API 661, but this standard does not provide any guidance on tube velocity limit. TEMA provides rho-v2 to calculate tube side velocity, but it is explicitly...

Is there any restriction such as thickness, diameter or hazard level for using multi-segment heads on pressure vessels as per ASME VIII or AS 1210?

Do anyone have their experience to share about TEER valves? We've not used or even heard about these valves before. A quick google search showed that these are valves manufactured in China. Are there any global experience to share about this product? We've asked for a Global reference, but...

I know this question was raised few years back by one of the members, but have not been able to find any response from Forum members. I'd like to raise it again to the forum as we are facing similar issues with hammer unions being used in our well flow line design. This is following on from...

Peers, I'm looking for some advice for non-metallic pipe support packer material which can withstand low temperature. Piping is low temp CS A333Gr6 and will see temp as low as -60C during blowdown. There are some structural contact point which requires to be isolated from low temp pipe...

Is ASME VIII Div 2 and 3 designed vessels acceptable in Australia? One of our clients in Australia has raised a request for high stress vessels to be designed to AS 1210. We don't design / fabricate to AS 1210 and hence provided suggestion to design the vessel to ASME VIII codes. We've...

Thanks 2671, yes you're right... Sorry for my wording compliant defect. I meant compliant discontinuity. is it required to report the size of compliant discontinuity? If not reported how do the client know about the size as in the case of IP the significance of 1mm and 38mm are quite...

Thanks Metengr. Sorry for another question related to RT reporting. One of the testing contractors states that as per ASME V it is not required to mention the defect size in the report if the discontinuity complies to the code criteria. They reports defect size of non-compliant welds only. My...

In industry terms it is called as 'golden weld'. Pls refer if there is any company standard or client spec for this. Golden welds are generally 100% radiograph tested in lieu of pressure test. I remember B31.3 mentions something similar for closure welds in the testing and examination. Pls...

Metengr -Thanks. I've read it already, which does not answer my question. My query is whether both depth and length of IP shall be within the acceptable criteria to pass the weld or not. In the table for notation 'B' has two line items which are not separated by an 'and' or an 'or'. RT...

Peers, As per ASME B31.3 Table 341.3.2 Acceptance criteria for welds, is it important to meet all the acceptable values mentioned in the criteria. For eg. lack of root penetration for Normal and Category M fluid - Girth, Miter groove and branch connection shows B as acceptance criteria...
