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...
