Min design temp is -150degF. t=1 3/16". PWHT @ 1100degF localized to affected areas. i.e. the SA-203 E sections welded. I do realize the heat will transfer to the 304L, but it should be plenty good for it. I am not sure why this would affect filler metal classification though. If the filler...

Thanks a bunch. Properties look exactly like what I am looking for.

I have a base material of SA-203 E on a vessel that I need to add a section of SA-240 304L. I am trying to write a WPS for GTAW & SAW processes for making the girth welds. I have been told by my welding consumable vendors that ER309L wire will not suffice due to the 3.5Ni content of the SA-230...

For the B31.3 piping, hydrotest durations are usually called out for by the project engineer. If you are the project engineer, B31.3 only requires a 10min leak test providing that all areas can be checked for leaks in 10min. If not, then test duration should be as long as it takes to ensure...

Don't you think it better than to ask the competition for help? Ha! Most of the guys on here work for or own their own facilities. They may not want to add to the RFQ pool. I have been working on layout & design of a new B&PV shop as well. I've just flat outgrown what we're in. You need to...

Seamless is typically much more expensive these days, but you should be able to find it to whatever wt you require. ERW pipe can be manufacutred to whatever WT you require as well & is usually more cost effective, if the code allows its use for your application. The grade of material will...
