Flare Tip Material - 310 S

Flare Tip Material - 310 S

(OP)
Do we need PWHT for flare tip material 310S ?

Also I check in B31.3 which gives for P-8 (310S group), PWHT requirement for all thickness but does not indicate the Temperature and the holding time as indicated for other materials.

Please advise.

RE: Flare Tip Material - 310 S

B31.3 Table 331.1.1 indicates no PWHT required for this material.

RE: Flare Tip Material - 310 S

If the flare tips were cold formed, you may want to re-think a thermal treatment.

RE: Flare Tip Material - 310 S

I examined a flare tip last year that had crumbled for reasons that included severe sigmatization. We went with Inconel 625 on the replacement.

I think you need to define what part of the flare tip, since they have a number of components.
