STOPKIT Test - Ø14” & Ø6” Pipe Spools Set up 14”Ø Pipe 6mm Hole at Plain Pipe6”Ø Elbow 4mm Hole at Weld Heat Affected Zone Note:- Both pipe spools were Hydro tested at 120 BarG prior to drill to perform the STOPKIT TEST

Arresting an air Leak Under 7.0 BarG Pressure. Ear protection required due to high noise level. Leak Arrested at 10 N.m Torque. STOPKIT Test at 14ӯ Plain Pipe with a 6mm Hole Note:- After air test the spool was filled with water and successfully tested at 80 BarG - 20 N.m Torque

Water Leak with Initial Pressure kept at 2.5 BarG. As the leak rate started to be reduced the pressure was gradually increased to 80.0 BarG to assess the STOPKIT performance. STOPKIT Test 6” Elbow with a 4mm Hole at Weld HAZ
