PN10 isolation joints are steel joints used for the sectioning of low pressure (10 kg/cm2) service lines for gas and water. Isolation joints provide cathodic protection in all piping systems and serve as a positive leak proof long lasting block against the flow of electrical current. The installation of insulating joints on service lines guarantees a superior security of the pipeline and significantly reduce maintenance costs.
The Female-Female PN10 joints are threaded joints (internal parallel threads ISO7/EN10226-1) completely factory assembled. These characteristics make the installation easy and fast. Female Female PN10 joints are available in small diameters ranging from ¾ in up to 2 in (see the whole range of diameters available in the table below). PN10 Female Female isolation joints are supplied from stock. Meccanica Segrino isolating joints are manufactured in accordance with the requirements of UNI-CIG, ASTM and API.
