Could you send out me the method of restoring the distortions in the shell and joints. How many times we are able to restore in a weld seam?. our client spec for peaking is 13 mm and banding is seven mm only. we've been struggling a great deal . tank capacity is 20000m3.
Ø Inspection look what i found by radiographic approach is not required for roof-plate or bottom-plate welds, for welds signing up for roof plates to top angle, the highest angle to your shell plates, shell plates to bottom plates, or appurtenances to tanks.
Saya mau minta details tentang storage tank operator, kira2 skill yang dibutuhkan apa saja ya pak? dan metode dalam mengoperasikan storage tank tersebut seperti apa? apa cara mengoperasikan n maintenance aboveground storage tank dan underground storage tank see it here berbeda? jika ya, berbeda dalam hal apa?
Peaking Banding menggunakan sweep board lalu ditempelkan di sambungan dinding shell tanki bagian dalam. Peaking untuk arah vertikal sedang bending untuk arah horizontal.
Assamualaikum, saya ingin bertanya mengenai peaking & banding. Sekarang saya terlibat dalam kerja membuat storage tank & kaedah yang kami gunakan untuk erect tank adalah jacking method, that's we need to erect the tank ranging from leading to bottom. So we previously completed the 12th training course until eleventh class such as the roofing. Them my QC truly presently did the peaking and banding for shell check here plate but a number of the readings were exceed the tolerance given in API 650 continue reading this and that is +-13mm.
paling lama 6 bln………kalo pak lukman sekarang dmn? oya…ya pak…salam ama org BBB, skrg poject dimana pak?sehabis ini saya masih sekitar merak……klo jd saya jd pegawai tetap aja…..cape pak muter2
Ø In the event the ensuing thickness is fewer than least necessary special info According to hydrostatic check structure circumstances, re-welding is needed.
Taj, on Oct sixteen, 2011 at two:31 pm reported: Dear Mate ,your web site aid me alot, and many thanks aiding folks by means of your web , and i want to know about tank staircase internal stringer plate hole marking and outer plate gap marking to fix the phase , i bought drawing although not very Obviously mention even acquired reply from engineering dep that layout at web page, i dont know what's the method of staircase radious marking
Btw mas Ifan lakukan prediksi bola pengukuran peaking & banding pada waktu in good shape-up atau setelah pengelasan? Untuk kedepan sebaiknya lakukan pengukuran peaking & banding pada waktu suit-up jadi kalau tidak masuk toleransi bias langsung ditanggulangi. many thanks
Iya pak memang tidak saya bikin detil,..dan hanya mencakup pada waktu building saja. Makasih atas sarannya.
Bubbles or foam produced by air sucked throughout the welded seam will reveal the existence of porosity in the seam.
Plumbness: Diukur dari paling atas sampai bawah tidak boleh melebihi batas toleransi (one/two hundred) dari tinggi tanki dan untuk tiap shell toleransi plumbness tidak boleh melebihi flatness & waviness my sources dalam STD ASTM A6.
As I understand wobbling related to grouting. could it be your poor encounter? I'll delighted for those who inform me the story why it transpire to my e mail at [email protected]. Thanks
Ø Repairing defective welds shall be finished by chipping or melting out the defects from a single or each facet of joint, as demanded, and commence with re-welding. All fixed welds are issue being re-examined as specified higher than.
