Re: [MW:5690] stroge tank API 650

We just had a lot of discussion in a project, API 650 only states that bottom should be "as flat as possible" this is not satisfactory for supervisors or owners...

Dear  Ramesh,
 
We have been faced same problem in our previous project.I agreed with you that API 650 does not stated clearly about bottom plates distortion.
 
In best my knowledge we need to minimize the distortion as much as we can during welding.I strongly recommended you to use low heat input and use good condition automatic welding machine.
 
Thanks
