1. Is related to the SOUR service. The NACE MR 175 standard will explain the reason.
2. Should have been RTJ. Unless if it was to match existing RF flanges. Might be an error in the specification. If you find please tell the group.

Subject: [Man.Distr][PipingDesign] LTCS pipes in higher dia?

Hi folks!!!!!
In some of the shell piping classes(eg 251440) i noticed that
1.Upto 6" A106 gr.B is specified .However above 8" A333Gr.6 (LTCS ) is specified.I wanted know the reason Why LTCS is required for sizes 8" and above. 2.The flanges are specified as RF (even in 2500# rating )
instaed of RTJ.Is RF better than RTJ in higher rating flanges?

rgards
