Hi Everyone,
Is there a provision in the ASME Piping codes that restricts welding of welding neck flange connection directly to a pipe elbow fittings? If there is none, will this normally affect hydraulics in the pipeline system.
Appreciate your response. Thanks.
Hi Everyone,
Is there a provision in the ASME VIII code that prohibits flame cutting as a procedure to remove welding connecting the temporary attachments such as lifting lugs to the shell or head plate of a pressure vessel?
Appreciate any response.
Thanks.
Hi Everyone,
When an API 650 tank is dismantled and relocated to a new location, can it be welded on its existing weld joints? Or is it required to cutoff the Heat Affected Zones (approx 2in) on each sides/edges of the plate before rewelding? The API 653 only states that "the existing weld...

Hi Everyone,
I would like to ask assistance on developing WPS for butt welding of SA 724 Gr.C plate 38mm thick using FCAW Process. Are there any resources you can give to study the welding and cutting process and essential/critical variables to be considered?
Thanks
Hi Everyone,
Just want to ask if what is the effect of Cr on A36 Plate if the percentage content is 0.30%. Generally what is the effect of Cr on carbon steel and will it affect the weldability of A36 plate?
Appreciate your comments and advice.
Thanks
Hello Everyone,
I would like to ask the Minimum Design Metal Temperature allowed by ASME VIII Div.1 for SA 517 Gr.F material. I have read Part UHT and UCS to find some answers. Will UCS 66 apply to SA 517 and under what group?
Appreciate your comments.
Hi Everyone,
Is there provision on the standards like NFPA,API or UL that permits fabrication of double wall tanks in lieu to construction of bundwall or containment wall in a tank farm?
Tank is aboveground, horizontal with 55,000 liters capacity.
Appreciate your comments.
Thanks
Hello Everyone!
What is the latest technology for measuring plumbness of a field erected vertical storage tank? Is there a laser type equipment approved by standards to determine plumbness of a vertical storage tank?
Hi everyone,
Is there any code requirements for ullage of LPG storage in pressure vessels? Is above 85% liquid LPG volume content for a aboveground pressure vessel permitted?
Thanks
For carbon steel materials, what is the commonly used value for corrosion rate to determine remaining life of vessel or tank in number of years? The vessel is located in terminal approximately 1 kilometer from the seashore.
Is it required in ASME VIII to conduct UT lamination check of steel plates? If not, when is it required? Is it also respective to thickness of plates?
Appreciate your comments.
What would be the recommended software to use to analyze a piping network in determining pressure drop and could able to recommend pump size. I understand that there are certain software like AFT Fathom, Pipe FLO, Fluid Flow, etc. But what would the best based on your experiences. Thanks!
I am looking to a complete guide in determining anchorage requirements of tank as per API 650. Do anyone have a sample calculation?
Appreciate any help on this.
Can someone provide any sample design calculations of stiffener rings based on Appendix A of EEMUA 190. Is there other helpful references (e.g. handbook)?
Any help would be appreciated. Thanks.
Good day!
Is there any case that overlapping of welds is permitted by ASME or any code? For example, overlapping of fillet welds of saddle reinforcing plate to the shell circumferential butt welds.
Thanks.
