Dear experts,
My question is, after welding our clint wants us to do pickling and passivation on the welded A312 TP316L stainless steel. But they want to do pickling on the inside of pipe as well (weld area). The thing is we are purging weld from inside until weld is finished and cooled down...

Dear all,
I checked the API 1104 but couldnt find anything explains this directly. Normally in ASME Sec.IX when you ran a PQR with butt weld you are qualified to fillet welds also.
But in API 1104 in essential variables section code only states joint design like V to U bevel. Is there any...
Good morning,
I am working with piping company which specialized on only aboveground pipeworks. And there is an upcoming pipeline work that we will possible get awarded.
Our old procedures are outdated, could anyone explain me current pipeline works. I mean is 2-3 group stick SMAW welding...

Good evening,
I have a procedure based on stick SMAW electrode E7018-G-H4R SFA 5.5 numbered.
Am I allowed to use SFA 5.1 numbered E7018-1 H4 electrode instead. Is it strictly essential variable or are there some variations. Code is API 1104, but couldnt find in it.
Thanks,
Dear all,
Im kinda stuck at welder qualification of branch welds. We have a nipoflange which connects to pipe's surface directly (with bevel and full penetration) but since it is not a butt weld and has nearly 20mm thickness I couldnt find anything related to this in ASME SecIX. Is this...
Dear all, I have a question regarding P45 materials welding. I have a qualified WPS that made with UNS N08020 (SB729) PQR. And I want to use this procedure on Alloy 20 which is UNS N08825 numbered material.
According to ASME you can weld the materials that are in the same P number and G number...
Good morning,
I have a question regarding welder qualification (performance records) procedures for HDPE pipe electrofusion butt weld. I couldnt find any reference in ASME standards for;
- After welder test, qualified diameters, thickness range
- Qualified materials (I will use HDPE PE 100 SDR...
