Vacuum Insulated Piping

Vacuum Insulated Piping

As an alternative to the conventional foam insulated piping, Cryeng Group offer Vacuum Insulated/Jacketed Piping (VIP/VJP) to suit customer requirements.

 

The piping is designed in accordance with ASME B31.3 and is suitable for inner pipe sizes ranging from 80DN (3NPS) to 1500DN (60NPS) and individual pipe lengths ranging from 6m to 30m long.

 

Award from BechtelAward from BechtelCryeng Group have successfully completed multiple large scale projects for Bechtel using Vacuum Insulated/Jacketed Piping with a total length of piping in excess of 8 km. Bechtel recognised Cryeng for "Outstanding Performance in Support of the APLNG Project"

 

Vacuum Insulated/Jacketed Piping offers the following benefits over the conventional foam insulated piping:

 

  • Thermal insulation performance: 6 to 10 times improvement in thermal performance compared to foam insulation. This offers a substantial reduction in boil off rate.

     

  • Space saving: Insulation space is 50mm thick (radially) whereas foam insulation is typically 400mm thick. This saves installation space/footprint by 700mm in both horizontal and vertical directions.   Pipe supporting structures such as jetties, modules or platforms can become more compact.

     

  • Time saving: Core pipes remain cold much longer (many weeks) between use, thereby eliminating the need for subsequent cool-down processes if idle periods are less than 2 weeks. This saves time for loading/unloading LNG from the ship.

     

  • Money Saving: Cheaper jetty construction and less LNG boil-off.

     

  • Structural Integrity: Much more durable and less prone to accidental damage. No need for heat-break for pipe supports.

     

  • In-service Inspection: Much easier to monitor and inspect pipe conditions and maintain.
