Could you send out me the method of restoring the distortions in the shell and joints. How again and again we could mend inside of a weld seam?. our client spec for peaking is 13 mm and banding is 7 mm only. we're struggling lots . tank capacity is 20000m3.
b. All radial joints in between sections of the drip rings, in addition to between the drip ring and the annular plate or base, shall be
Welds that fail to fulfill the factors provided in paragraph over, shall be reworked just before hydrostatic screening as follows :
Ø Vacuum box tested utilizing a test force no less than 3 psi gauge or as specified on corporation specification.
seven. In any case designed up end you can try here and hole of welding line is okay, more about the author match up vertical joint and put in stiffener / crucial plate in The placement of buckling place
all rectangular and sketch plates (bottom plates on which the shell rests that have one particular close rectangular) shall have a minimum amount
untuk vacant yang bagus lagi sepi bro…tapi coba deh loe buka petromindo.com…disana banyak banget vacant yang continue bagus…coba aja…oh iya untuk metode air raisingnya loe share ke anggara_wi54@yahoo.
I am sorry…I never develop specification for vacuum box however, if u want to establish vacuum box specification I recommend to Stick to the rule in API 650 but much more strictness. Please talk about it along with your engineering Section
5. constructed up plate over the welding line if index any size of plate has shortness mainly because chopping of weld metallic.
Iya pak memang tidak saya bikin detil,..dan hanya mencakup pada waktu building saja. Makasih atas sarannya.
Iya pak masih bisa. Buckling atau tidaknya lebih banyak disebabkan karena konstruksinya bukan materialnya (selama materialnya bagus).
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 A6.
As I am aware wobbling associated with grouting. can it be your lousy expertise? I'll delighted for those who notify me the story extra resources why it occur to my electronic mail at [email protected]. many thanks
nine. After finish weld from out facet check the radius of buckling plate and location once again working with stiffener and Key plate
