Max wall thickness
Max wall thickness
(OP)
What is the over thickness limit for SA333 Gr 6 pipe, I checked SA999 but it shows only minimum wall thickness requirement.
My vendor did some boring on sch XS pipe to bring it to sch STD but now thicknees is over by 22%
should I accpet or reject?

I do not have copy of A333 but SA 333 cetainly do not have table 7.
Can you help me waht tolerance specified in table 7 in A333?

RE: Max wall thickness
So it means SA333 do not have over tolerance limit for wall thickness, under para 10.2 of SA999 bored pipe has over thickness limit of 3.2 mm so Iwill go by that

A bit confused here so hopefully someone can clarify.
Why would there be any concern on pipe being thicker than it is supposed to be ?
If it is STD piping and a length of XS pipe or an XS fitting is installed it is no problem as long as the ends are transitioned as per code requirements.
The only issue would be the time / cost to smart143 to perform the transitioning themselves.
If the time/cost is an issue then reject it - 22% over thickness does seem way too much.
