Comprehensive STOPKIT Testing of Ø14" & Ø6" Pipe Spools with Hydro and Air Tests

This document details the STOPKIT testing procedures for Ø14” and Ø6” pipe spools. Both spools were hydro tested at 120 BarG before drilling for STOPKIT tests. The Ø14” plain pipe received a 6mm hole test, arresting an air leak under 7.0 BarG pressure, while the Ø6” elbow was tested with a 4mm hole at the weld heat-affected zone (HAZ). Initial tests revealed a minor leak, which was resolved through strategic pressure increases up to 80.0 BarG. The final results confirmed successful leak arresting in both configurations, ensuring system integrity.

Presentation Transcript

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

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

  3. STOPKIT Test 6” Elbow with a 4mm Hole at Weld HAZ 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.

  4. STOPKIT Test 6” Elbow with a 4mm Hole at Weld HAZ 40 N.m Torque Applied Pressure 80.0n BarG Minor Leak - Tear 44 N.m Final Torque Leak Permanently Arrested

  5. STOPKIT Final Test at 80.0 BarG - Ø6”Elbow & Ø14” Pipe 6” Elbow 80.0 BarG 14”Ø Pipe

  6. STOPKIT 100 – Large Pad for Major Leaks STOPKIT 100 25mm Hole on Plain Pipe Pressurized up to 36.0 BarG. Evidence of Leak at around 30.0 BarG. Pressure Stabilized at 25.0 BarG – Leak Stopped

  7. STOPKIT 50 – Smaller Pad for pinholes STOPKIT 50 4mm Hole on Top of the Weld - Tested up to 36.0 BarG. No Evidence of Leaks
