Hi Gents,
We're facing very difficult situation for Aramco project as below.
Following is the requirement of SAES-H-002.
5.2.9 "The internal coating shall be extended up to the face of flat-and raised-face flanges that will not be in contact with the gasket. The coating applied shall be...
Hi Gents
I'm looking for WPS(or PQR)using ASTM 904L Steel + DIN 1.4539 material which is equvalent to Corten steel.
As alternative, it's equvalent to P No.45 + P No.3.
If any body has it, please share it with me. (starships@naver.com)
Thanks

We're fabricating the pressure vessel. But due to short length(approx. 5~6mm) of plate with width of 1,000mm, we're planning to do buttering welding at joint to recover the gap.
Is it possible and allowable way? Relevant PQT will be performed and witnessed by Authorized Inspector...
Metengr, thank you for answer.
As you mentioned, minimum value as well maximum is also important to ensure mechanical properties don't lower. But, we can't find how much of hardness value is acceptable as minimum in any standard and code application.
For said material, our client has required...
Thanks for answer.
Requirement for minimum allowable hardness value is the comment from our client.
As mentioned in original thread, reference code just mentions maximum allowable hardness value (248 HV 10).
Client wants to know minimum hardness value on welds(incl. HAZ & base metal) after...
Hi, everyone
Anyone guy telll me the minimum hardness value for welded joint of P355 NL1 EN material?
Relevant standard(EEMUA 190) only shows maximum hardness value. This is our client requirement.
As I know, all hardness value is limited to maximum value not minimum.
Thanks
Good day to you,
We're performing repair work for pressure vessel
That fell down to the ground during lifting, and then after window-cutting damaged area, now on welding.
But, our client has insisted to carry out PWHT after repair welding for replacing patch. Originally, PWHT was not required...
This is the horizontal-type vessel containing Liquefied Petroleum Gas.
Length (From T.L to T.L) is 52,800mm.
There are two repair locations. One is located at the bottom of vessel and, another is located on the side of vessel. Both locations are so far on the vessel (Approximately, 30,0000mm)...
Greetings
We're doing repair work for pressure vessel as per EN 13445.
Repair work means "cutting deep dent-damaged area and re-welding with new plate as square size".
After re-welding, localized PWHT as per client's requirement has been planned. But, we're worried about deformation during...
