pak saya lagi problem berat nih, saya ada kerjaan melakukan leveling tangki yang sedang di hydro, menggunakan theodolit tapi saya tidak bisa olah info nya, mungkin bapak punya tutorial and spreadsheetnya kalo berkenan tolong di bagi pak (sedikit banyak sangat membantu) thanks ya pak.
b. All radial joints read review among sections on the drip rings, along with amongst the drip ring along with the annular plate or bottom, shall be
Welds that are unsuccessful to satisfy the factors offered in paragraph click for more info previously mentioned, shall be reworked before hydrostatic screening as follows :
Ø Vacuum box tested employing a exam pressure not less than three psi gauge or as specified on Company specification.
ada pasal nggak dalam API 650 yang mengatakan untuk menentukan penggunaan annular plate atau langsung base sketch…oh iya apa effectnya klo pada region bottom kita nggak menggunakan anular plate? Salam
paling lama six 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 If the resulting thickness is fewer than minimum amount required as per hydrostatic examination structure ailments, re-welding is necessary.
I am sorry…I by no means develop specification for vacuum box but if u want to develop vacuum box specification I propose to follow the rule in API 650 next but a lot more strictness. be sure to go over it with all your engineering Section
Mohon kiranya structure laporan inspeksi tersebut dapat dikirimkan juga ke email saya sebagai referensi Pak
Iya pak memang tidak saya bikin detil,..dan hanya mencakup pada waktu construction saja. Makasih atas sarannya.
Bubbles or foam made by air sucked throughout the welded seam will show the presence of porosity inside 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 dalam STD ASTM A6.
Maaf ni agak lama balasnya,..knowledge yang mas Ifan berikan belum komplit jadi agak susah nelaahnya. Berapa tebal plate? Berapa ukuran stiffener angle nya? Materialnya apa? Deformasinya di product try this out atau di pengelasannya?
Ø Repairing defective welds shall be carried out by chipping or melting out the defects from just one or the two aspect of joint, as required, and carry on with re-welding. All fixed welds are subject matter to become re-examined as specified above.
