Ukubaluleka kwe-ASTM A139 kulwakhiwo lweMibhobho yeGesi yendalo engaphantsi komhlaba
Umbhobho wentsimbi yekhabhoni odibeneyo ojikelezayo owenziweyoI-ASTM A139Yenzelwe ngokukodwa ukusetyenziswa komhlaba njengeenkqubo zokuhambisa igesi yendalo kunye nokusasazwa kwayo. Le mibhobho yenziwa kusetyenziswa inkqubo ekhethekileyo yokuwelda eyenza iindawo eziqinileyo nezihlala ixesha elide, ezibalulekileyo ekunyamezeleni uxinzelelo lwangaphantsi komhlaba kunye neemeko zokusingqongileyo ezi mibhobho iza kujongana nazo.

Inkqubo yokuwelda ejikelezayo esetyenziswa kwi-ASTM A139 inika umbhobho umphezulu wangaphakathi ohambelanayo nogudileyo, nto leyo ibalulekileyo ekuqinisekiseni ukuhamba kakuhle kwegesi yendalo kumbhobho. Le mibhobho ikwafumaneka kwiindidi ezahlukeneyo zobubanzi kunye nobukhulu bodonga, nto leyo evumela ukuguquguquka kuyilo kunye nolwakhiwo ukuhlangabezana neemfuno ezithile zenkqubo yokuhambisa okanye yokusasaza igesi yendalo.
Ukongeza ekuthembekeni nasekuqineni, umbhobho we-ASTM A139 unika ukumelana nokugqwala, nto leyo ibalulekileyo ekuqinisekiseni ukuba imibhobho yegesi yendalo engaphantsi komhlaba ihlala ixesha elide. Izinto zentsimbi yekhabhoni ezisetyenziswa kwezi mibhobho zenzelwe ngokukodwa ukumelana nokugqwala, ukuqinisekisa ukuba imibhobho ihlala iphilile kwaye ayivuzi kangangeminyaka ezayo.
Ukhuseleko lubaluleke kakhulu ekwakhiweni kwemibhobho yegesi yendalo engaphantsi komhlaba. Imibhobho ye-ASTM A139 yenziwa kwaye ivavanywa ngokwemigangatho engqongqo yeshishini kunye neenkcukacha, ukuqinisekisa ukuba inokumelana nemingeni eyahlukileyo yokusetyenziswa komhlaba. Oku kunika iinkonzo zegesi yendalo, abalawuli kunye noluntu uxolo lwengqondo besazi ukuba iziseko ezibonelela ngegesi yendalo zithembekile kwaye zikhuselekile.
Ukuqukumbela, i-ASTM A139umbhobho wentsimbi yekhabhoni odibeneyo ojikelezayoIdlala indima ebalulekileyo ekwakhiweni kwemibhobho yegesi yendalo engaphantsi komhlaba. Ukuqina kwayo, ukumelana nokugqwala kunye nokuthobela imigangatho yeshishini kuyenza ibe yeyona ifanelekileyo kwiiprojekthi ezibalulekileyo zeziseko zophuhliso ezifana nale. Xa kufikwa ekuqinisekiseni ukhuseleko, ukuthembeka, kunye nokusebenza kakuhle kweenkqubo zokuhambisa nokusasaza igesi yendalo, ukusebenzisa umbhobho we-ASTM A139 sisigqibo esingenakubekwa ngqalelo. Ngokukhetha izixhobo ezifanelekileyo zezi zicelo ezingaphantsi komhlaba, sinokuqinisekisa ukuba iziseko zethu zegesi yendalo zihlala zikhuselekile kwaye zithembekile kwizizukulwana ezizayo.
