isowell is a flexible, longitudinally welded and spirally corrugated HYDRA® stainless steel pipe, particularly suited for secondary piping networks with high requirements to pressure and temperature.
isowell pipe consists of a stainless steel pipe and a PE-LLD jacket pipe. Both are bonded together into a firm structure by flexible polyurethane insulation. The pipe is auto-compensating – a flexible alternative to rigid pipes during the connection process.
Longitudinally watertight composite system, certified according to 15632-4, FW 420.
Flexible isowell pipes ≤ ø50 are equipped with a diffusion barrier to eliminate diffusion of cell gas. This diffusion barrier ensures a permanently low heat loss throughout the service life of the flexible pipes.
