The multi layered spiral coiled urea reactor with inner liner of 316L (Mod) and 40000 mm TL to TL (tangent to tangent length) leaked during hydro-test after ATR-2019 which in turn resulted in the failure of the outer carbon steel shell of 8 mm. This study briefs about the extent of damage, refurbishment procedure and inspection techniques that were carried out during the repair work so as to ensure better reliability of the equipment during normal running hours.
