FlexiGas 22mm Double-Sleeved Flexible Gas Pipe (DS-22) – 75m Spool is a pre-sleeved, twin-layer CSST gas pipe supplied on a 75-metre spool. Its pipe-in-pipe construction is designed to provide an integrated sleeve, while the flexible stainless-steel tube can be routed in continuous runs by a qualified installer using the current manufacturer instructions.
The supplied product information lists BSI Kitemark KM 598726, EN 15266 and a maximum operating pressure of 0.5 bar. FlexiGas currently says its DS range is in transition and directs installers to its technical team to confirm availability, documentation and the appropriate product for a job.
