The tank is 12m diameter, 9m tall.
Over half the circumference of the shell to bottom weld is cracked and corroded, including the first 100mm or so of shell which requires replacement.
API653 does not specify the...
Hi there,
What are peoples thoughts on de-rating the tensile strength of bolts which have been galvanised?
I am designing multiple flanges which will be assembled using AS4291 / AS1110 Grade 8.8 bolts which will be galvanized. I realise that hydrogen embrittlement generally occurs in bolts...
Hi All,
I have noticed a few people out there are using VVD by Ohmtech. Could someone please let me know if the software has the capability to solve (determine) the flange thickness for a non-standard flange design? Or if there is any other alternative software that can do this?
I am designing...
G'Day,
Would anyone know the material properties for old Carbon Steel Plate (AS1548-1-430).
In particular I am after the tensile strength, Yield Strength and design allowable stress (MPa).
The plate was used in a heat exchanger designed to AS1210-1977 (Pressure Vessels).
Could anyone tell...
