On-Line Leak Sealing

Wellube’s Online Leak Sealing services is a proven service applied to a diverse range of pipelines, valves, and pressure vessels.

Maintain Pipeline Integrity with Wellube’s Online Leak Sealing Services

Leakage sealing is now widely regarded as a cost-effective repair option for standard metallic materials in the oil and gas industry. Safe and effective online leak sealing is supported by stringent procedures and practices in the petrochemical, oil and gas, power production, gas distribution, and nuclear industries. A leaky fuel oil pipeline can be repaired without the pipeline being isolated/shut down, or drained.

When a substantial leak occurs in a pipeline within a continuous process facility, three alternatives are often available to resolve the problem. The first method includes shutting down the pipeline for traditional repair, the second letting the leak continue for a limited time, and the third repairing the breach while the pipeline continues at full pressure and temperature.

Pipeline leaks can occur at flanges, straight pipes, elbows, tees, and valve glands, among other places. This is owing to the nature of the pipeline contents, particularly where the flow is turbulent and the pipeline is prone to corrosion and/or erosion, such as near elbows and tees or at a flange junction or a valve. It can also happen at pipeline weld sites where the pipeline material is not uniform.

How does leak sealing work?

Online leak sealing is a process of sealing leaks in pipes and other equipment without shutting down or dismantling the system. It’s a rapid and low-cost method for correcting leaks and preventing additional system damage. Here’s a quick rundown of how online leak sealing works:

1. Inspection:

The first step is to identify the leak’s source. Several methods, such as visual inspections, thermal imaging, ultrasonic testing, and pressure testing, can accomplish this.

2. Preparation:

The next step is to get the area around the leak ready. To do this, the surface may need to be cleaned, any dirt or rust removed, and a coating applied to seal off the leak’s immediate vicinity.

3. Sealing:

After the area has been cleaned up, a specialised injection tool is used to apply the leak sealing material to the leak site. Usually a polymer resin or epoxy, the substance is made to flow into the leak and then harden to form a seal.

4. Curing:

The sealing material must be allowed to cure for a while. Depending on the material used and the amount of the leak, the drying time may change.

5. Verification:

The system is inspected after the seal has dried to ensure the leak has been fully sealed. To ensure that the seal is holding, this may entail pressure testing, flow monitoring, or other sorts of testing.

Repairing leaks in various systems, including pipes, tanks, and vessels, is incredibly effective when done online. It is a quick, inexpensive, and minimally intrusive option that can lessen the need for costly maintenance and downtime.

Online Leak Sealing Service

Wellubes Online leak sealing services have been divided into two categories:

  • Specialised Leak Sealing;
  • Online Leak Sealing
Specialised Leak Sealing

Sealing pressurised leaks while under continuous pressure to minimise costly shutdowns or unscheduled maintenance downtime is known as leak sealing.
Wellube has successfully sealed leaks in pressure and temperature ranges ranging from vacuum to 400 bar and -60°C to 600°C.

Some of the applications include:

1. Valve Packing:

Valve packing is an important part of the operation of valves, which control the flow of fluids or gases in pipelines, pumps, and other equipment. The sealing material applied around the valve stem prevents leaks between the stem and the valve body is referred to as valve packing.
Valve packing can become worn, cracked, or corroded over time, resulting in leaks and decreased valve function. This is when leak-sealing services online come in. They can assist in repairing valve packing leaks by employing specialised equipment and materials to seal the leak while it is still in operation.

2. Flange Joint Leaks:

There are numerous methods for achieving a seal on a flange, depending on the space between the flanges as well as temperature and pressure. This method is ideal for repairing low-pressure leaks. Because almost all flanges are manufactured to standard sizes, a two-piece flange clamp can be placed and then injected to stop the leak. The flange of standard size Clamps in sizes 12″ through 24″ and class 150#, 300#, and 600# rated flanges are typically provided for quick turnaround to satisfy client emergency requirements. Other sizes of clamps may usually be created and fabricated in less than 24 hours.

3. Elbow Leaks:

Elbow Box Clamps are designed and manufactured by Wellube to fit specific pipe configurations. The sealing method can be an injectable groove or a composite seal created by Wellube.

4. Weld Leaks/ Pinholes:

Straight-Line Box Clamps are commonly employed to remedy these leaks. These are manufactured to the required pipe sizes, then installed and injected promptly to address your leak problems. T-Box clamps for sealing Tees, Reducer (Concentric/eccentric) Box Clamps, and even clamps that enclose and seal pipes in conjunction with fittings, flanges, valves, and so on are examples of these.
