18 Inch Water Pipe

18 Inch Water Pipe

18 Inch Water Leak at 60 psi

The leak in the Cat Cracker cooling water riser was exacerbated by being between a failed saddle clamp and the concrete surface. ERS was called in to avoid a shutdown of the Cat Cracker at $1,000,000/day.

  • After a thorough on-site assessment, the ERS engineering team designed a simple Leak Trap and had this rolled and fabricated at Schmidt to 4-in larger than the OD of the pipe.
  • The Leak Trap incorporated an oversize relief pipe and gate valve to carry away the leaking water during sealing.
  • The Leak Trap Clam Shells were fastened to the concrete with concrete anchor bolts, using ERS-2000W Water Guard Paste Grade, to seal residual leaks around the concrete joint.
  • This was then filled with ERS T-Screed and the Leak Trap lid was sealed in a similar manner with the relief pipe and gate valve on the outside.
  • After curing, the valve was closed and the water stopped completely.
