GAS supply system with yellow pipes (available in 5-meter rolls and bars) marked MOP 0.5 GAS which certify its approval for the domestic distribution of GAS and LPG according to the requirements of UNI TS 11344. The system BALPEXGAS in compliance with UNI GIG 7129: 2015 (Design, construction, testing and reconstruction of systems, or part of them, made with multilayer metal-plastic pipes) in accordance with UNI TS 11343, is suitable for GAS distribution networks in buildings for residential, industrial and commercial, public and hospitality purposes such as hospitals, retirement homes and nursing homes, hotels, schools, places of worship.

Design instructions

The standard reference in force in Italy for the design, construction and testing of a domestic and extra-domestic GAS distribution network is UNI CIG 7129: 2015 in accordance with UNI TS 11343. With respect to the construction of systems inside buildings, regardless of the intended use, Ministerial Decree N ° 37 of 2008 must be applied, which requires compliance with the rules of the art and the declaration of conformity of what has been achieved. All stages must therefore be carried out by personnel with the necessary technical skills and in possession of the requisites established by laws and regulations in force.

Installation method

Simple to install thanks to the malleability of the PEX/AL/PEX pipe and the speed with which the fittings are joined mechanically (press-fitting), with the use of special electrical equipment. The pipe-fitting seal is guaranteed by NBR O-rings mounted on the brass body of the fitting covered by a stainless steel bushing.
