When installing the gas piping system must ensure that:
Not Be Exposed To:
Thermal and mechanical stresses (e.g. From heating and convector installation, welding devices, gas discharge tubes, sun rays, open fires, vibrations or loads).
Atmospheric agents (e.g. UV rays) unless it has UV protected
Aggressive materials or means that favor corrosion.
Condensation water and the surface condensation of other pipes.
Permanent humidity (e.g. in damp environments).
Positioned near high tension wires, district heat ducts, and hot or cold water pipes.
Coming into contact with boiling discharged gases.
Weaken load-bearing parts al buildings or to serve as load-bearing parts of a construction.
Compromise mechanical stability, fire-protection systems, heat and acoustic insulation.
Positioned in lift cages, in places where there are transformers, in ventilation ducts or water discharge ducts.
Placed across chimneys, inside lateral ducts of the main chimney, or bracketed to chimney walls.
Used in combination with cast asphalt.
Forced into position.
During construction of the installation, all measures must be taken in order to prevent the infiltration of extraneous substances (e.g. dirt, water, dust) in the pipes themselves.
The openings of the ducts and the openings of the closure devices must be closed by adequate means.
Dissolved work residues, such as shavings (burrs) must be eliminated.
In the case of the presence of extraneous substances/elements inside the pipes and relative connections and additional safety system, these must be removed by blowing inert gas or air and with adequate means.
The route of the gas installation must be as short as possible and with as few connections as possible.
The gas installation must be constructed in such a way that the specifications below are respected.
When faying the network, stresses (e.g. twisting) on, for simple, meters and other components must be avoided.
The pipes must be positioned in such a way as to avoid the risk or damage to the mechanical parts (e.g. by hoisting equipment or during transport).
The route of the pipes must be chosen in such a way as to exclude the risk of damage (e.g. perforation or jamming).
In the case of the use of perforators, tackers, staple guns, etc. A sufficient safety distance from the installed pipes must be respected.
In the case of installation in the vicinity of reinforced concrete (spacers), care must be taken in order to avoid damage to the pipes themselves caused by sharp metal parts or other building components.
Adequate safety measures (e.g. warnings, protections) must be taken to ensure that the gas installation cannot possibly be damaged.
