Our remote area client required a custom leak seal solution to seal and stop a medium pressure Steam Leak while the plant remained on-line, under pressure and temperature.
Leak sealing utilises specialist compounds and a mechanical retaining device to effect a seal. The process combines stringent procedures and risk assessments with highly experienced trained personnel and specialist equipment to ensure a safe process and an effective seal.
BLJ technicians were required to design and manufacture a clamp solution to meet clients specific application. They installed the peripheral seal clamp around the bonnet leak on the 6” 600# valve and utilised specialist compounds and a mechanical retaining device to effect a seal. Design Temp: 400 deg C. Design Pressure: 3800 Kpa.
Leak sealing and repair was completed with clamps designed to ASME VIII or AS1210 design codes.
This is a temporary fix to get the plant through to the next plant maintenance or scheduled shutdown, when the item is repaired or replaced to work within the clients timeframe and resources.
