This is just an idea that we came up during our discussion with the customer. If we need a short pipe, 3"LG, then we may be able to machine it from a round bar.
For example, we have received a coupling which was machined from a round bar A479 347/H with Carbon content above 0.04%.
So based on...
That is why I asked the original question. Because the piece of pipes that I need is 3”, I was looking to see whether it is possible to machine it out of a 347h round bar or not.
Thank you guys for the replys.
XL83NL,yes, based on b31.1, grain size coarser than 7 is a note for 316L for temperatures above 1000F.
I have difficulties sourcing 1/4”NPS 347H pipe.
Per B31.1, 316 can be used if carbon content is above 0.04%. 316L can be used if grain size is coarser than 7. Please correct me if I read it wrong.
Since the the pipes are usually dual grade 316/316L, it is difficult to find pipe with carbon content above 0.04%. So, I have to go with 316L and...
Hello folks,
I am designing a section of a stainless steel piping skid which is supposed to be operating at temperatures above 1000F. The governing code is B31.1. The pipe is going to be welded to a weldolet on one side and a tee on the other side. According to B31.1, A312 316L is acceptable if...
Hello folks,
I am doing the calculation for stainless steel piping with a temperature/pressure rating 400F/4000psi based on B31.1.
B31.1 note(12) for A182 F316 indicates "These allowable stress values apply to forgings over 5 in. in thickness." One interpretation of this note would be that the...
