SinglePipe® 85 SW

The LOGSTOR SinglePipe® 85 SW is a shallow water thermal insulation solution for offshore pipelines able to sustain depths up to 340 meters. The system is designed to be cost-effective and can be installed with any pipe-laying method.


A: Steel pipe
B: Fusion Bonded Epoxy
C: Water seal or PE Welding
E: PUR foam
F: HDPE casing
