Could you deliver me the tactic of fixing the distortions during the shell and joints. How often times we can easily fix in the weld seam?. our shopper spec for peaking is thirteen mm and banding is 7 mm only. we're struggling a whole lot . tank ability is 20000m3.
Ø Inspection by radiographic system will not be demanded for roof-plate or base-plate welds, for welds becoming a click here for more info member of roof plates to top angle, the very best angle on the shell plates, shell plates to bottom plates, he said or appurtenances to tanks.
apakah ada kemungkinan buckling saat pengelasan comprehensive weld? bagaimana cara untuk mencegah buckling saat horisontal full weld?
Peaking Banding menggunakan sweep board lalu ditempelkan di sambungan dinding shell tanki bagian dalam. Peaking untuk arah vertikal sedang bending untuk arah horizontal.
seven. All things considered crafted up complete and hole of welding line is fine, in good shape up vertical joint and set up stiffener / important plate in the location of buckling region

Ø When the resulting thickness is fewer than minimum expected According to hydrostatic exam style disorders, re-welding is required.
I am sorry…I under no circumstances create specification for vacuum box however, if u desire to produce vacuum box specification I recommend to Adhere to the rule in API 650 but a lot more strictness. you should go over it using your engineering Office
Btw mas Ifan lakukan panjang lapangan bola basket pengukuran peaking & banding pada waktu read full report healthy-up atau setelah pengelasan? Untuk kedepan sebaiknya lakukan pengukuran peaking & banding pada waktu healthy-up jadi kalau tidak masuk toleransi bias langsung ditanggulangi. Thanks
Apa yang saya tahu, in API 650, this tolerance normally use for regular erection that's from bottom check over here to prime. Correct me if I’m Incorrect sbb saya bukan datang dr qualifications QC. Ini kerana my shopper basically can’t acknowledge our final result simply because they make reference to API 650 aad they need explanation which can menjelaskan final result kami. So saya ingin nak tahu ada cara lain atau reference lain yang boleh membantu saya supaya saya dapat member clarification for my shopper disamping dapat menjaga kualiti kerja kami. TQ.
Iya pak masih bisa. Buckling atau tidaknya lebih banyak disebabkan karena konstruksinya bukan materialnya (selama materialnya bagus).
Plumbness: Diukur dari paling atas sampai bawah tidak boleh melebihi batas toleransi (1/200) dari tinggi tanki dan untuk tiap shell toleransi plumbness tidak boleh melebihi flatness & waviness dalam STD ASTM A6.
As I am aware wobbling related to grouting. could it be your bad encounter? I will pleased if you convey to me the Tale why it materialize to my e mail at [email protected]. Thanks
Ø fixing defective welds shall be finished by chipping or melting out the defects from a single or the two side of joint, as needed, and progress with re-welding. All repaired welds are matter to get re-analyzed as specified higher than.
