For gas lines in underground areas, UNI 10823
Pre-insulated copper pipe produced in compliance with current regulations and in particular with the Ministerial Decree. 37/2008 and compliant with UNI 7129-1 for gas distribution systems.
The copper pipe complies with the UNI EN 1057:2010 harmonized standard which allows the CE mark to be affixed to the product in compliance with the European Regulation 305/2011 relating to construction products and is made up of a CU-DHP alloy, annealed in deoxidised rolls phosphorus, with a minimum copper content of 99.9% and phosphorus content between 0.015% and 0.040%.
IsoPVC Gas
The sheath
Intrinsic characteristics of the sheath “ISOPVC GAS” are excellent plasticity, mechanical resistance to abrasion and corrosion and its durability over time.
The yellow PVC coating adhering to the copper pipe complies with the reference standard UNI 10823 Coated copper pipes for gas applications in landfill areas – External coating of plastic materials applied by extrusion.
The applications
Particularly suitable for the construction of underground gas distribution lines.
