Methane gas Pipe legislation

Legislation governing methane gas pipes and recommendations on their installation

Safety in the home must always be of foremost importance, as should the safety of those living there. We should always bear this in mind when speaking about methane gas pipes.
To this end, Uni issued the UNI-CIG 7140 standard through the Italian Gas Committee. Updated in 2013, this defines the reference standard for non-metal methane gas pipes which can be installed in housing to connect appliances with power of less than 35KW to the supply network.
The text includes recommendations on length, which should never exceed 1500mm in installations, and especially on protecting the user. It is recommended that each methane gas pipe bear a marking, repeated every 400mm, with the code and name of the manufacturer, the expiry date or limit of use, the internal size as a diameter and reference to the standard.   
Installation is performed by sector professionals, who can ensure excellent workmanship. Everything is fixed at the two ends with metal clamps to guarantee the seal and prevent release.
Once the methane gas pipe has been installed, it is verified that no point comes into contact with any heat source and especially that there is no throttling which could impair the characteristics. The surface should also be checked regularly to ensure that it is intact and, most importantly, it should be replaced within the expiry date. This is the only way you can be sure of having a safe installation.
