ONLINE LEAK SEALING
Common Leakage Of Pipeline
Valve Packing Leak
- This is the most common application for under pressure leak sealing services for many reasons.
- These valve packing leak can be repacked on-line very quickly and economically without shutdown or having to insolate the valve itself.
Flange Joint Leak
- Flange leak are an unfortunate common appearance in many facilities and can be easily sealed by using the on-line leak sealing technology.
- There are many different ways to achieving a seal on a flange depending on the gap of the flange and also temperature and pressure.
Pipe Fitting Leak
- The box enclosure clamps are manufactured to the standard pipe size and are fabricated in short radius or long radius application.
- Once the box enclosures are installed, they are injected with suitable sealant to perform a 100% guaranteed seal – injection groove/cavity filled sealing method is depending on pipe conditions.
Weld Joint Leak
- These enclosures are manufactured to various pipe sizes and can be installed and injected very quickly to avoid costly shutdown and further problems.
- Sometimes a strong back is used to give additional support or restraint to the pipe and clamp.
Heat Exchanger Leak
- The common leak sealing method used for heat exchanger leakage is the drill and tap method.
- The sealant selection is based on the medium, pressure and temperature – select a non curing sealing compound for it flow characteristics and for future re-injection purposes
Valve Bonnet Leak
- The common method used for valve bonnet leak is the drill & tap method, where we:
- Drill and tap a blind hole at the mid of valve body to suit an injection valve.
- A long series drill is use to break through the stuffing box body.
- A sealant is then injected to seal the leak through the injection valve.
Other Special Applications
- The common leak sealing method used for heat exchanger leakage is the drill and tap method.
- The sealant selection is based on the medium, pressure and temperature – select a non curing sealing compound for it flow characteristics and for future re-injection purposes
Pipe Crimping
- Pipe crimping method is use to provide a permanent isolation or to block off the flow on a live small size pipeline where there is no isolation valves is available to perform an isolation.
- The principle of the process is to crimp the pipe with crimping clamp and inject sealant at the upstream side to seal off flow/leakage.
Pipe Wrapping
- Flange leak are an unfortunate common appearance in many facilities and can be easily sealed by using the on-line leak sealing technology.
- There are many different ways to achieving a seal on a flange depending on the gap of the flange and also temperature and pressure.
Valve Killing / Valve Passing
- Valve killing is a perfect solution to stop a valve seat passing to achieve an isolation
- Sealant is injected into the upstream side of seat area to provide a safe seal and to stop the flow.
- The sealant will remain in the system and is usually caught in a drain if the valve is open again
- Valve killing is perform by using the drill & tap method – under pressure and no shut down!
Metal Paste
Metal paste services is a repair work to repair damage surface such as badly corroded pipe, leaking pipe, tank, roller, shaft, valve body (inside and outside), propeller, fin blade etc. We are using specialize two-part putty that incorporated with fibre cloth or wire mesh.
