TYPE OF LEAK
Oil and Gas
Special applications of online leak sealing
Passing valve seat (gate , globe , ball type etc.)
To provide isolation on the pipe by crimping clamp and sealant injection.
Leak Sealing Job on Gaskets of Bolted Assemblies
A safe and non destructive process!
With the view to limiting even more the stress on the flanges’ stud/bolts during the injection stage, all our clamps are designed with safety retainers called ‘’stiffeners’’.
Gasket of Flat Face Flanges
In case of a leak on the gasket of flat face flanges, the sealing is obtained by injecting a clamp machined with a central groove and by installing and injecting ring adaptors on all stud/bolts.
Leak Sealing Job on Pipes
The pipe is covered with a metal enclosure which is progressively filled up with our sealing compound.
With Protective Sleeve
In order to limit the potential risks of compound intrusion into the pipe line, a protective sleeve could be placed over the leaking point before installing and injecting the metal enclosure.
When the leak is located on the weld seam, we foresee its degradation and further potential disconnection over time by systematically designing a strong back clamp device, either connected to the metal box itself or separate.
The leaking pipes showing a high corrosion level and very thin residual thicknesses will be dealt by means of a ‘’premoulded box’’, without injecting sealing compound.
Leak Sealing Job on Valve Gland Packings
A leak located on a valve stuffing box is usually dealt with a G Clamp placed around the packing box area. Then, a drill is operated all through the G Clamp down to the packing. This ‘’break through’’ method creates a channel for injecting our sealing compound.
If our on-site assessment shows that the nuts of the packing gland flange are faulty or damaged, strengthening metal blocks will be installed before injecting sealing compound.
