RE: [MW:6340] Power boiler repair before start up

Ask AI for the actual clause wording to see if he is correct, I suspect
not as we have done the same as you want to do with no issue. In any
case I see no problem if the welders are qualified for the other
company's WPS variables etc. If not get them qualified and continue as
you suggest.

Dear All,

Thank you for your valuable inputs.

Boiler manufacturer's supervisor is with us to co ordinate the repair
work.But they don't have manpower over here to execute the repair.So
they would like to hire our welders.But Authorised Inspector opposing
that idea by quoting some clauses from ASME BPV Section -I PG 1.2 and PG
1.2.3. Can vendor use ourqualified welders in this situation?Anybody
have an idea to get out from this trouble.

We planned to cut the burner front wall tubes by keeping 500 mm in
length at both header ends(top and bottom).Corrosion visible on the mid
portion of the tubes.I think the refractory block is the villain in this
case.


Regards,


Limesh

If your company certified as S stamp manufacturer you could take
the job. Please check ASME Sec I Para 104.1

Anyway I wonder , are you absolutely sure that the corroded
needs repair (or may be replace), since it is new one, what is the
repair planned ? do you have suitable WPS/PQR for repair work ?

I suggest you to take the picture, take UT thickness check and
ask the manufacturer/designer if this really needs to be repaired.

Dear All,

One of the boiler's burner front wall tubes found
corroded.Boiler is
new one and not yet commissioned.Boiler assembled by us.Can I
use my
company's or hired welders for a boiler repair constructed by
other
company? ASME Authorised Inspector denied our request to utilise
our
welders.AI advised us to bring the welders from the manufacturer
side
for repair.Which code clause justifying his comment?

Regards,


Limesh
