Stainless steel flexible pipes with plastic protective sheath
Stainless steel flexible pipes meet the UNI CIG 9891 standards which provide the external protection in plastic polymer
The stainless steel flexible pipes, also called ‘to continuous wall’, are devices that are normally used for connecting users to the domestic gas distribution network, replacing the rubber pipe. They can also be used for water conduction.
The stainless steel flexible pipes can also be covered by a plastic sheath, but this should not be structural. That is, it must not contribute to the resistance of the pipe during the tests of compliance with the standards. The only purpose of the sheath is the protection against abrasion, with the foresight to choose a material that does not degrade or corrode the external surface of the pipe.
But the peculiarity, as we have often said, is that the stainless steel flexible pipes are extensible and adaptable to any domestic connection, always keeping in mind that their length must not exceed twice the initial compressed length.

The reference standards for stainless steel flexible pipes are UNI CIG 9891 and UNI CIG 7129
