Thin Film Type Shell & Tube Heat Exchanger Tubes Reclaimation

[sahsanb]

Dear All,

We are facing repeated leakage issues from Carbamate Condensers and Stripper in our Urea plant. Leakage sites are T-TS seal weld and internal groove formation at HAZ area of tube itself. Leakage occurs in top 10-15 mm of tubes or its seal weld. Please share if Please share your experience w.r.t. reclaiming tubes by using thin metallic inserts. What are the best known companies for this? and will it effect the thin film formation in our Stripper?

Regards,
Ahsan
