Could you send me the tactic of restoring the distortions in the shell and joints. How over and over we will repair within a weld seam?. our client spec for peaking is 13 mm and banding is seven mm only. we are struggling a whole lot . tank capacity is 20000m3.
b. All radial joints involving sections on the drip rings, along with bonuses in between the drip ring plus the annular plate or base, shall be
Welds that are unsuccessful to fulfill the criteria discover supplied in paragraph over, shall be reworked just before hydrostatic testing as follows :
Ø Vacuum box tested using a exam stress at the least 3 psi gauge or as specified on corporation specification.
7. All things considered constructed up end and hole of welding line is ok, in shape up vertical joint and put in stiffener / crucial plate in the location of buckling location
Sebaiknya anda tanyakan ke design and style engineer anda. Disini hanya membahas hanya permainan sepak bola berasal dari dari sisi inspeksinya saja. Thanks
Ø Should the ensuing thickness is below minimal needed as per hydrostatic take a look at style disorders, re-welding is needed.
nanya dunk, boleh nggak klo pada spot bottom tank kita nggak make annular plate, hanya menggunakan bottom sketch.
Mohon kiranya format laporan inspeksi tersebut dapat dikirimkan juga ke e-mail saya sebagai referensi Pak
Apa yang saya tahu, in API 650, this tolerance normally use for standard erection and that is from base to best. proper me if I’m Incorrect sbb saya bukan datang dr track record QC.

mau tanya untuk mengatasi tangki yang secara Visible gembung (platnya) menggelembung sebagai akibat pembukaan plat ketika rebottoming harus dilakukan apa/ trus kalau dilihat dari segi kekuatan bagaimana cara ceknya, cara mengatasinya bagaimana, jika tangki ring one , satu paltnya dibuka cara pasangnya bagaimana agar tidak gembung lagi.
9. immediately after finish weld from out side Verify the radius of buckling plate and environment once again utilizing stiffener and essential plate
