i have some penemu sepak bola issue about welding inspection , my question is can we try here utilize vaccum box tests in butt weld joint for roof or base. ( for Misc tank)
com. thks banget bro atas bantuannya…satu lagi man…loe tau rumus untuk menghitung radial anullar nggak? or cara menentukan manhole di roof…
Welds that fail to satisfy the factors presented in paragraph earlier mentioned, shall be reworked previous to hydrostatic screening as follows :
Ø Vacuum box examined using a take a look at stress at the very least three psi gauge or as specified on organization specification.
Assamualaikum, saya ingin bertanya mengenai peaking & banding. Sekarang saya terlibat dalam kerja membuat storage tank & kaedah yang kami gunakan untuk erect tank adalah jacking system, which can be we need to erect the tank ranging from major to base. So we currently finished the 12th training course until 11th system including the roofing. Them my QC in fact presently did the peaking and banding for shell plate but find here a lot of the readings have been exceed the tolerance supplied in API 650 which is +-13mm.
Sebaiknya anda tanyakan ke design and style engineer anda. Disini hanya membahas hanya penemu sepak bola dari sisi inspeksinya saja. many thanks
saya mau bertanya bagaimana penemu sepak bola menentukan /rumusnya panjang dan lebar dan juga diameter untuk membuat tangki solar?
I'm sorry…I by no means produce specification for vacuum box however, if u choose to establish vacuum box specification I advise to Keep to the rule in API 650 but far more strictness. make sure you go over it using your engineering Office
five. developed up plate around the welding line if any length of plate has shortness for the reason that slicing of weld metal.
Apa yang saya tahu, in API 650, this tolerance ordinarily use for regular erection which is from base to best. Correct me if I’m Mistaken sbb saya bukan datang dr background QC. Ini kerana my client actually can’t take our outcome because they check with API 650 aad they need rationale which will menjelaskan end result kami. So saya ingin nak tahu ada cara lain atau reference lain yang boleh membantu saya supaya saya dapat member clarification for my client disamping dapat menjaga kualiti kerja kami. TQ.
6. just after end created up he has a good point check weld steel with Dye Penetrant take a look at to assure the weld is sweet and no crack.
Ø around thirty inches in the seam below examination is brushed by using a soap Resolution basics or linseed oil. The vacuum box is positioned above the coated part with the seam, and bonuses a vacuum is placed on the box.
Maaf ni agak lama balasnya,..information yang mas Ifan berikan belum komplit jadi agak susah nelaahnya. Berapa tebal plate? Berapa ukuran stiffener angle nya? Materialnya apa? Deformasinya di material atau di home pengelasannya?
note: pls Verify the Vacuum box Bottom Rubber,for the reason that rubber is destruction the vacuum trouble.(not arrive at vacuum 76 cm Hg)
