PN10 insulating 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 Male-Female galvanized PN10 joints are threaded joints (external taper thread and internal parallel thread ISO7/EN10226-1), zinc coated and completely factory assembled. Threads make the installation easy and fast, while the zinc coating make the product more resistant to corrosion.Male-Female galvanized PN10 joints are available in small diameters ranging from ½ in up to 2 in (see the whole range of diameters available in the table below). PN10 Male-Female galvanized joints are supplied from stock. Meccanica Segrino isolating joints are manufactured in accordance with the requirements of UNI-CIG, ASTM and API.Insulating Joints tested and manufactured in accordance to UNI-CIG 10284
