On-Line Leak Sealing
Leak sealing is the process of sealing pressurized leaks while under continous pressure to avoid costly shutdowns or unscheduled maintenance downtime. Due to this Technology industries now enjoy greater plant uptime maximization, environmental impact minimization and risk reduction.
|Valve Gland Packing
This is the most common application for under leak sealing services for many reasons. Valve Gland Packing can be repacked on-line very quickly and economically without shutdown or having to isolate the valve itself. The sealant used to seal these leaks is very similar to the original packing material supplied from the valve manufacturer and will not harden or ruin the valve. Some common application for these valve gland packing repairs are steam, superheated steam, water, condensate, chemical, vacuum, air, or almost any process.
Wellube design and Elbow Box Clamps, to suit the pipe configurations. The sealing method can be either an injectable groove or the Wellube developed combination seal.
There are many different ways of achieving a seal on flange depending on the gap between flanges and also temperature and pressure. For flange gaps below 6mm a Wire insert technique is normally performed. This process is excellent for low pressure leaks. Since almost all flanges are built to standard sizes, a two-piece flange clamps can be installed and then injected to arrest the leak. Standard size flange clamps for sizes ½” thru 24” class 150#, 300# and 600# rated flanges are normally stocked for a quick turnaround response time to meet client emergency . Clamps for other sizes can normally be designed and manufactured in less than 24hrs. The same techniques can be used for Heat Exchanger joints, Turbine joints, etc.
|Weld Leaks / Pin Holes
Straight-line Box Clamps are used regularly to repair these leaks. Manufactured to the required pipe sizes, these are installed and injected very quickly to eliminate your leak problems.
