    SAW weld for ASTM A333 Gr. 6 (deviation from standard)

    Tracing back the error, in our pipe specification it was mentioned that only SAW welded pipe is acceptable and ERW is not accepted. It seems that someone at some point referring to pipe specification made a change to PMS although in the basic PMS the welding of A333 was specified as ERW. I...

    SAW weld for ASTM A333 Gr. 6 (deviation from standard)

    Thank you. So as the pipe is used in low temperature service, I think that we have to reject the material.

    SAW weld for ASTM A333 Gr. 6 (deviation from standard)

    Hi. I have a question regarding the welding of A333 materials. In our "Piping Material Specification (PMS)" the welding type for welded A333 Gr. 6 pipe was specified as SAW but according to ASTM A333 no filler material shall be used for the welding of this material: Now, the vendor claims to...

    Pipeline Flange 1500# standard (equivalent to mss sp 40)

    @GDD Thank you for your reply but I don't understand what you mean by MPC. Can you tell me what does it mean? thanks. @r6155 In the basic engineering this material is selected and is referenced to MSS SP 44 which is not correct. So no, there are no valid documentation about how this material...

    Pipeline Flange 1500# standard (equivalent to mss sp 40)

    Thank you for your replies. Yes I meant mss sp 44 and the pressure is 190 bar and the temperature is 93 C. @The Obturator Thanks for the link. But the according to mss sp 44 for temperatures below 100 the working pressure up to class 900 is similar to A105 which is different from the table of...

    Pipeline Flange 1500# standard (equivalent to mss sp 40)

    Hello In our system we have a 1500# pipe line and the material of the flange is A694 F52. The pressure rating of the material is covered up to 900# in mss sp 40 but 1500# is not covered. In which standard can I find the pressure rating for the 1500# flange of this material? Thanks. (Also, since...

    Problem creating a Tee

    Thanks. That didn't work. I'm trying to draw the pipe from the tee, but it starts with a gap from the tee. Changing dx doesn't solve this problem, however, if I decrease the distance, it will start at the same place but draws the line toward the tee (left to right). I'm not even sure whether it...

    Problem creating a Tee

    Hi. When trying to create this specific tee, the software does not display the pipes properly and there is a gap between the pipes. And only this one has problem, there is no problem in other elements and tees. I checked the nodes and there seems to be no error. I also closed and re-opened the...
