Online Leak Sealing Clamp Systems

Under-Pressure Leak Sealing is the ability to affect a seal on a leaking component without the need for down time and lost production.

Typical Applications: valve glands, flanges, valves, pipelines.
Variety of product: steam, hydrocarbon, gas, chemicals, water.
Pressure: Up to 10000 psi, typical applications are 2500psi and below
Temperature: Up to 1080 C can be sealed, most typical applications are below 300 C.

Under pressure leaks are one of the most common causes of unscheduled shutdown in plants, refineries, often resulting in safety hazards and environmental issues. When no isolation is possible to carry out repairs, Thirran Energy (TEN) leak sealing capability is equipped to perform on line leak sealing on almost any item of plant. Our team of leak sealing service technicians are trained, experienced, and conversant with many and diverse leak scenarios. TEN worked and partner with reputable leak seal principal providing engineering support, procedures, supervision, sealants sales & supply.

More Information about Leak Sealing Clamp Systems

There are two basic types of full-encirclement steel sleeves. The Type A sleeve functions as reinforcement for the defective area by welding two pieces of steel sleeves longitudinally. The Type B sleeve is welded in the same manner as the Type A sleeve but, in addition, the ends of the sleeve are welded circumferentially to the carrier pipe. This type of repair is capable of repairing leaking defects or defects that may leak in future because the ends are fillet welded to the carrier pipe.

Besides welded sleeves, steel clamp repair is another alternative for repairing corroded steel pipes. Instead of welding, the sleeves are joined by mechanical fastening such as Type C Bolted Sleve. The operation principle of the previously mentioned repair systems has proved to be effective by restraining the corroded section from bulging, hence the reinforcement. The long-term performance of steel repair systems is a great advantage which contributes to the relevance of this system until now.

There are several shortcomings in the repair systems mentioned. For example, Tye A and Type B Steel Sleeve methods are generally suitable for straight pipe sections but not for joints or bends. For joints and bends, Type C Bolted Sleeve are more applicable however for short term only. Besides that, welding or clamping of pipelines is bulky, costly and time consuming especially if the pipelines are underground. In most cases, heavy machinery is required to perform this cumbersome job.
