Flame arrester series

Oxygen-suppressing flame extinguisher

|Product introduction

Widely used in oxygen transportation pipes in metallurgy or chemical industry, the oxygen flame arresters can effectively cut off fire produced by impurities rubbing the pipe walls in the fast flow. Connect the product with oxygen transportation pipes and it works. This flame arrester is applicable to oxygen pipes DN15-500mm, working pressure no more than 4MPa. Flange and welding are both available.
 
FP-XT oxygen flame arresters and FPV-XT oxygen flame arresters are used separately before and after the valves. They are welded by special Cu alloy and stainless steel and can prevent flame produced by adiabatic compression or high speed operation.

|Installation and maintenance

Maintenance
1. The flame arresters should be checked every 6 months.
2. Blocked flame arresting cores should be cleaned, and broken flame arresting layers should be changed.
3. The joint surface should be rigorous when reinstalling the flame arresting layer cores.

|Order notice
