Re: [MW:15426] ALIGNMENT OF LINE

Dear Friend,

Refer A530 clause 14, general requirement of CS pipe and alloy steel
pipe .It says that the seamless pipe should be reasonably straight and
give tolerance for welded pipe.
Secondly Asme B31.3 says that for angular misalignment above 3degree
design consideration changes .
We have to consider both above point ,and this is one of the reason
that code doesnt specify for alignment issue thinking that if pipe is
manufactured as per the above standards and angular misalignment is
within the limit there will be no issue for alignment .
I consider above points while doing inspection.
