Material is A36 and the tapered side of the pin is fillet welded on the distribution gas pipeline to abandon the service (100 psi max) using an in-service welding procedure. The sketch is not to scale. I am not considering plugging 1/4x20 threaded hole on top of the pin an in-service weld.

Thanks!

Hello all Can I apply ASME B&PV sec IX procedure (6010 & 7018) to fill up 1/4" hole at the end of 1/5" pin? Kind of plugging the hole to prevent corrosion. Sketch of pin is attached. Thanks! https://res.cloudinary.com/engineering-com/image/upload/v1607390772/tips/Pin_Sketch_-_Copy_tb6han.pdf

What if pressure go up to 30 psi?

Hi, I was wondering what is the design standard for the equipment an piping system if pressure is below 15 psi? This a pneumatic system for launching golf ball. Thanks

Hi, Any idea on long seam weld rejection or repair rate at mill for Submerged-Arc welded steel pipes (NPS 36 heavy wall like 19.1 mm)? Thanks

Thanks! it helped alot

I am looking for ASTM A 572 Gr 60 or 65 plate with wall thickness of 0.875" or higher and CE>0.39% or any equivalent material. I will appreciate any help.

Hello all, We have following two welding procedure to butt weld API X52 NPS20 X 12.4 mm pipe. My first option would be procedure#1; however, is there any issue welding with procedure#2? Thanks for your inputs. #1 root E6010 hot, fill and cap E7010 #2 root E6010 hot E8010 fill and cap E8018

Your comments much appreciated!

Does lamination scan require prior to cathodic(cad) welding on pipe? Please let me know why?

Thanks

Hi, I am looking for some information regarding the pipe fabrication methods. Is there any preference regarding SMLS (Seamless) v ERW (Electric Resistance Welded) v DSAW (Double Submerged Arc Welded) for station piping with MAOP of 650 to 900 psi? Cheers

Hi, I would like to know how long LH electrods can expose to atomosphier without baking or redrying. Do we need to rebake LH electrodes in 350C if the welder turns off the portable oven ,which was in 130C, for 1-2 hours (let's say for break)? Thanks

I appreciate your thoughts on this. We need a ASME sec IX welding procedure to cover welding P1G1,2,3 to P1G1,2,3. I want to cover up to 1 inch wall thickness. Proven impact property ir required. I noticed companies are using two PQR welding dual rated 516 Gr60/70 to group 3 plate in 0.249 and...

SJones, Does API 579-1 covers gas transmision pipelines?

Thank you sir.

Hi, I appreciate any input on this. Two corroded area reported on NPS 36 9.5mm wall. Pipe is X65-448 gr. Corrosions do not meet our criteria to repair (RPR is > 1) based on general corrosion. I wanted to get your thoughts on the close proximity of these features to the welds. They do not...

thanks littleinch. we were told by consultant that this amount of tensile strain might be close to tensile strain capacity depends on the size of flaw in girth welded area and they agree to weld a reinforcement sleeve. Pipe is 414 grade, 30"OD X 9.5 mm.

Thanks Racookpe, analyzing data by FEA reveals that we have deformation and axial strain is less than %1 and close to tensile strain capacity. Deformation caused compression in top and tension in bottom. Deformation located in girth welded area but it passed the inspection and no defect...
