[MW:1099] Cold Bending of SS.304 1.1/2" size pipe / tube

You may use Table UHA44 (ASME Sec VIII div1) for PFHT requirement, which is most common in HE  U tubing.

Para 331.4.2 not clearly spelt out for P8 material, but there is something called 10% strain limit, which is same as given in UHA44 for 304 material

Hi,

Is there any code restriction for doing cold bending of SS-304 (1.1/2") pipe? Any post bending heat treatment required?
31.3 only specifies heat treatment for ferritic steel.

thanks & Regards,
Dhwani
