atex methane pipe

Hi.
Domandona:
typical threaded joints in the methane line (also of the home lines) generate atex zones?

Thank you.

typically connections (which are threaded or flanged) are always associated with emissions, which depend on the fault hole (the rules say what to consider) and pressure: the fact that then you create or not an area depends on the extent of the emission range and ventilation. if the emission range is low and/or good ventilation, the dangerous area may have negligible extension. the norms have changed in recent years, and I no longer deal directly with atex calculations for a long time: something has changed, but the principle remains this.

I think like you... let's see if there's any other idea

Hi, mir,

in principle your interpretation may be correct.
I think we should understand where this joint is carried out.
In particular, if the ''junction'' is carried out on an external adduction line for example, it is hardly possible to create a concentration so that it can give rise to explosions. different speech if such joint is made in tunnels or vaults not properly designed.
I think we have to understand the geometric space around the junction. .
