For underground gas lines, UNI CIG 7129
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.
Suitable for underground passages thanks to the particular shape of the sheath section which has special air chambers suitable for merging any gas leaks up to the outside of the building.
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%.
Isoclima Gas
The sheath
The sheath produced by ISOCLIMA, when adhered to a non-combustible support, melts without developing a flame; it is therefore self-extinguishing.
Principali caratteristiche della guaina di “ISOCLIMA GAS” sono le camere d’aria presenti all’interno della sezione della guaina stessa.
These have the specific function of conveying any gas leaks to the exit of the building.
The applications
“ISOCLIMA GAS” trova il suo migliore impiego negli impianti gas “sotto traccia” all’interno dei fabbricati secondo quanto richiesto e prescritto dalla UNI CIG 7129.
