Protectem Flangebelt in cold/cryogenic insulation systems

Advantages of the Protectem Flangebelt:

Protectem-Flangebelts ? are mainly used in hot insulation systems to detect leakages in flange connections or are used for personal protection at high pressure flange connections systems, the so-called sprayers.

Also in cold/cryogenic insulations systems Protectem-Flangebelts? can be applied as a solution. 

Current situations:

Only pipework is insulated. And insulation of valves and flange-connections can only be done after a successful leakage and pressure test. These tests are always done in the final stage of the project which comes with extreme time pressure for insulation contractors.

Suggested solution:

First install Protectem-Flangebelts? with Teflon seal and leak-pipe at flange connections. Insulate the flange connections and valves and make sure that the leak-pipe sticks outside the metal plating. Leak and pressure test can be executed after the insulation is completed. Possible leakage will be detected/sniffed through the leak-pipe. After a successful testing leak-pipes can be removed, and the cavity filled with Handi-Foam? and the metal cladding finished with Tembutil-IF. The Protectem-Flangebelt? remains under the insulation.

Benefits:

•  The entire piping system can be insulated without interference of leak testing.
• Less risks delay of start-up of the plant.
• Cost reduction and efficient final commission.
• No workload peaks for contractor during final stage of the project.

When following the original installation procedures all flange connections can be insulated after a successful leak/pressure test, bringing a tremendous peak in the contractors workload. By installing Protectem-Flangebelts? this peak can be flattened out over the entire project. And if during final testing a flange-connection leakage is found, only the insulation at the leakage has to must be removed, the leakage dissolved and the flange-connection re-insulated.

This method has proven to be more efficient and results in costs reductions, higher safety and guarantees the start-up date.
