Do you have the right flame arrester?

Recently we have some minor fire incident at the offsite area. Of all the places, it happen at the flame arrestor (in-line). Fire was put out and lines isolated. We strip the arrestor ( housing and banks) and found a big gaping hole in the housing (facing the bank) and sign of corrosion (with cracks) on hte nozzle.

Cause of failure. . housing is cs steel and nozzle is 316. galvaniz corrosion + material is not fit for service. We've ordered new sets of banks but we've upgraded the housing.

Bishop and Knitel has written a simple guidelines in choosing a denonation arrestor that appeared in the Feb 1993 issue of Hydrocarbon Processing. Received on Wed May 30 01:28:00 2001
