1″ leaking valve body
The body of the valve was leaking from behind the flange bolts. The line was still in service running at 15 bar g.
8″ CAT feed line
The 8″ line had suffered from severe external corrosion at the air / soil interface which had resulted in several through wall defects. The client required an engineered composite system which would seal the leak and give a long term design life.
6″ Stainless Tee
The line had suffered from two cracks next to the welds on the 6″ Tee
12″ Fire Water Line
The 12″ line had suffered from severe external corrosion and resulted in a through wall defect. The client required an engineered composite system which would seal the leak and give a long term design life.
14” High / Low Pour Blend Stock Line
The 14″ line had suffered from severe fretting where the pipe was being supported. The client required an engineered, long term design life composite repair with extra work at the 6 o clock position for the support to be reinstated.
3″ Heating Medium
The line had suffered severe internal corrosion resulting in a pin hole leak.
4″ CIP Line Repair
Composite repair to seal leak and reinstate integrity to the line.
14″ Strainer
This line was operating at ambient temperature with 16 barg of pressure when online. The strainer had two areas of severe internal corrosion resulting in small weep areas on the front body of the strainer which required an engineered composite solution.
1.9″ Carbon Steel Nozzle
This tank was operating at ambient temperature with atmospheric pressure. The nozzle had a small weep on the weld which required sealing before the engineered composite was applied.
