A patch for repairing pipes of FZV type (hereinafter referred to as a patch) is used to repair locally damaged steel pipelines (e.g. damaged by corrosion or mechanical impact) with no leakage of medium or with leakage of medium, with the highest value of operating pressure up to 40 bar.
Other dimensions should be consulted
Permissible overpressure of medium in the damaged piping when the patch is being applied:
max. 500 kPa
Permissible leakage of medium out of the damaged piping when the patch is being applied:
max. 50 m3/hour
For other technical parameters following 5.2
