Re: [MW:12321] Query / Machining of Sch 40 to Sch 30 / 24" RF WN Flange

Is it mean trimmed/chamfered? Code is allowed, you can see the sizes/figure in the B16.5 book, but certain customers require ID of flange same with ID of pipe.

Subject: [MW:12316] Query / Machining of Sch 40 to Sch 30 / 24" RF WN Flange

Dear All,

 

I would like to know whether standard ASME B 16.5 do allow machining of bevel edge to achieve required thickness?

The material is  24" WN RF Flange A105 ,Class 150- NACE , Normalised.

 

We are not able to procure standard fitting and done machining to achieve Sch 30 from Sch 40. Please note, not to entire length.

The dimension and thickness is verified and a Certificate of Compliance is produced.

 

Please advise with evidence(supporting Code) whether the material could be ACCEPTABLE.

 

Thanks & Regards

Vino-Doha
