Could you mail me the tactic of fixing the distortions during the shell and joints. How over look at this now and over we will mend inside a weld seam?. our shopper spec for peaking is 13 mm and banding is 7 mm only. we've been struggling quite a bit . tank capability is 20000m3.
b. All radial joints amongst sections of the drip rings, in addition to in between the drip ring as well as annular plate or bottom, shall be
Welds that fall short to fulfill the criteria supplied in paragraph previously mentioned, shall be reworked just before hydrostatic screening as follows useful content :
Peaking Banding menggunakan sweep board lalu ditempelkan di sambungan dinding shell click now tanki bagian dalam. Peaking untuk arah vertikal sedang bending untuk arah horizontal.
7. In any case Built up end and hole of welding line is okay, fit up vertical joint and put in stiffener / vital plate in The placement of buckling spot
Sebaiknya anda tanyakan ke style and design engineer anda. Disini hanya membahas hanya bola 168 dari sisi inspeksinya saja. many thanks
Ø When the ensuing thickness is less than minimum amount required According to look what i found hydrostatic test layout disorders, re-welding is required.
nanya dunk, boleh nggak klo pada area base 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 commonly use for standard erection and that is from bottom to major. appropriate me if I’m Mistaken sbb saya bukan datang dr history QC. Ini kerana my customer actually can’t acknowledge our outcome since they confer with API 650 aad they want reason that could menjelaskan result kami. So saya ingin nak tahu ada cara lain atau reference lain yang boleh membantu saya supaya saya dapat member rationalization for my consumer disamping dapat menjaga kualiti kerja kami. TQ.
6. soon after complete designed up check weld metallic with Dye Penetrant test to assure the weld is good and no crack.
Plumbness: Diukur dari paling atas sampai bawah tidak boleh melebihi batas toleransi (one/200) dari tinggi tanki dan untuk tiap shell toleransi plumbness tidak boleh melebihi flatness & waviness dalam STD ASTM click over here now A6.
mau tanya untuk mengatasi tangki yang secara visual 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.
nine. soon after finish weld from out facet Test the radius of buckling plate and location once more working with stiffener and important plate
