Flare Tip - Softening of SS310
Flare Tip - Softening of SS310
(OP)
Recently removed a flare tip from service (refinery) after 8 years in operation. Flare tip body is constructed of SS310 and is severely distorted.
DPI shows scattered surface porosity and also some cracking (photos).
Hardness test reported 100-120HV, which seems alot softer than original mill cert - 220HV.
Wondering repair methodology for cracking - replacement, or grind out cracks and pad weld.
What does the softening mean? Carburisation? Service is mostly methane/ethane, sour.
Any input appreciated
