    WT4x7.5 A992 Tee Piping supports for ASME B31.3 Piping

    That actually helps out a lot. Do you know of any reputable suppliers in the US for the W8x15 beams?

    WT4x7.5 A992 Tee Piping supports for ASME B31.3 Piping

    Im looking to see if anybody has experience fabricating piping supports from A992 Ibeams/Tees. I say Ibeams or tees because i cant gather if fabricators take i beams and cut the flange off one end or order a tee that only has a flange on one end. I have a current bid to do where the drawing...

    ASME B31.3 impact tested EFW SA-312 pipe per table 323.2.2

    Hello all, I had a quick question on SA-312 304L impact test requirements per b31.3. on EFW pipe since there is not filler material deposited to weld the joint does the pipe have to come impact tested at -320 per table 323.2.2 A-4(b)? The hardest part for me is getting over where it says "weld...

    ASME Sec. IX Duplex Stainless Steel weld qualification

    All, I recently had a job come up that is SA-790 Duplex Stainless steel. In the past years we qualified a procedure where the customer required impact testing where the minimum thickness qualified was 5/8". The current job i have has thicknesses ranging from .280" to .375". with the...

    Tracking RT failures

    That actually sounds like a great idea. Could you PM me an example spreadsheet you use at your workplace?

    Tracking RT failures

    All, Ive recently been tasked to develop a system to track and record RT failures in our pressure vessel welding shop. Currently our quality team believes since we are not recording this therefore it is leading us to believe we are being too lienient on x-ray failure percentages on a per welder...

    Imact testing at -50 Deg. F and subsize specimens to ASME Sec. VIII

    All, I am having issues deciding on how to destructively test some procedure qualifications that i am trying to do. The tests consist of a P1 Group 1 to P1 Group 2 .375" thickness and another plate test of the same materials thats .750" thickness. Im having trouble deciding if ill need to lower...

    304 Stainless Steel Permeability Check

    All, I have a customer that wants all their stainless steel pressure vessels to be below 2.0 mew magnetic permeability. Problem is that they were fabricated without production knowing of this requirement and consequently they are all failing. I do know of the proper steps to prevent this from...

    Inconel 625 Cold Working

    Thats a great suggestion ill need to get with my purchasing group to get a max yield strength and minimum elongation requirements added to any inconel 625 tubing we order. We do order it solution annealed but we then again anneal it to develop an oxide coating on the outside of the tube for...

    Inconel 625 Cold Working

    Am i correct saying solution anneal temperature is from 2000-2150 Deg. F and then followed by a rapid water quench?

    Inconel 625 Cold Working

    All, Currently in our shop we are heating 1/2" diameter 0.065" wall tubing filled with a magnesium oxide to 1600 Deg. F then rapid water quench to prevent cracking during bending. The inner radius of the material when bent is a 3/4" inner radius. We are currently having issues with cracking...

    ASME Sec. IX Small diameter Procedure Qualification

    Figure QW-462.1(e) shows requirements for Tension tests but do you still do root and face bends on that small of diameter pipe?

    ASME Sec. IX Small diameter Procedure Qualification

    All, I am currently trying to qualify a small diameter procedure qualification on SS Tube 0.500" diameter .035" wall. I am confused on the destructive testing needed to fully qualify to section IX. In QW-451.1 it says anything less than 1/16 thickness needs two tension specimens, two face and...

    ASME Sec. VIII 2013 Div. 1 Repairs question

    If the code book used for repairs is the Nation Board Inspection Code part 3 and it doesnt mention anywhere in the code removal of Heat affected zones after so many welding repairs then it shouldn't be an issue regarding how many times a joint has been repaired?

    ASME Sec. VIII 2013 Div. 1 Repairs question

    I am trying to figure out if there is a limit on repairs of a weld joint before the HAZ needs to be cut out. Currently we repair a part for a customer about once a year and we continually have done this on that part about 8 times. Neither UG-78 or UW-38 cover anything on this so im stuck and...
