I've some sepak bola question about welding inspection , my query is can we utilize vaccum box screening in butt weld joint for roof or base. ( for Misc read review tank)
Ø Inspection by radiographic approach hop over to these guys just isn't necessary for roof-plate or bottom-plate welds, for welds becoming a member of roof plates to leading angle, the very best angle to the shell plates, shell plates to base plates, or appurtenances to tanks.
Welds that fail to meet the criteria offered in paragraph previously mentioned, shall be reworked previous to hydrostatic tests as follows :
Ø Vacuum box tested employing a take a look at force not less than three psi gauge or as specified on firm specification.
ada pasal nggak dalam API 650 yang mengatakan untuk menentukan penggunaan annular plate atau langsung bottom sketch…oh iya apa effectnya klo pada place bottom kita nggak menggunakan anular plate? Salam
all rectangular and sketch plates (bottom plates on which the shell rests that have a single close rectangular) shall Have a very minimum amount
Apa kabar pak???, saya Alhamdulillah dalam keadaan sehat wal’afiat. Maaf saya menanyakan hal yg saya anggap baru buat saya.
nanya dunk, boleh nggak klo pada spot bottom tank kita nggak make annular plate, hanya menggunakan bottom sketch.
five. designed up plate within the welding line if any duration of plate has shortness for the reason that slicing of weld steel.
Background saya teknik sepak bola sipil, tapi diminta mengevaluasi plumbness dan roundness oil storage tank. Bapak Lukman, tolong saya minta dibantu untuk informasi common plumbness dan the original source roundness (no code dan isinya)
Bubbles or foam produced by bonuses air sucked in the welded seam will reveal the over here presence of porosity within the seam.
Plumbness: read this Diukur dari paling atas sampai bawah tidak boleh melebihi batas toleransi (1/two hundred) dari tinggi tanki dan untuk tiap shell toleransi plumbness tidak boleh melebihi flatness & waviness dalam STD ASTM A6.
Maaf ni agak lama balasnya,..info yang mas Ifan berikan belum komplit jadi agak susah nelaahnya. Berapa tebal plate? Berapa ukuran stiffener angle nya? Materialnya apa? Deformasinya di product atau di pengelasannya?
Ø restoring faulty welds shall be finished by chipping or melting out the defects from a single or both facet of joint, as needed, and carry on with re-welding. All fixed welds are issue for being re-tested as specified previously mentioned.
