Ukubaluleka kwe-ASTM A139 kwi-Pipeliel ye-Pipeliel yeNdalo

Ukubaluleka kwe-ASTM A139 kumgangatho wokwakhiwa kwegesi yendalo ebonakalayo

Inkcazo emfutshane:

Xa yakha phantsi imibhobho yegesi yendalo, kubalulekile ukusebenzisa izixhobo ezifanelekileyo ukuqinisekisa ukhuseleko, ukuqina kunye nokusebenza kakuhle. Isixhobo esinye esiqhele ukusetyenziswa xa sakha la malungu egesi ngu-A139, olona phawu lusemgangathweni we-spilbon ye-spilbon yentsholongwane. Kwezi bhlog, siya kuphonononga ukubaluleka kwe-ASTM A139 kwi-Pidiel yegesi yendalo kunye nendlela idlala ngayo indima ebalulekileyo ekuqinisekiseni ingqibelelo yokuqinisekisa ukuthembeka nokunyaniseka kwezi zinto zibalulekileyo zeziseko zophuhliso.

Iimpawu zeMveliso

Imibhobho ye-SPIRL ye-SPILD ye-Carbon yentsimbi yenziweI-ASTM A139yenzelwe ngokukodwa izicelo eziphantsi komhlaba ezinjengokuhambisa igesi yendalo kunye neenkqubo zokuhambisa. Le mibhobho yenziwa kusetyenziswa inkqubo ekhethekileyo yeWolding edale udibaniso olunamandla nolomeleleyo, olubaluleke kakhulu ekuphuculeni uxinzelelo olungaphantsi komhlaba kunye neemeko zokusingqongileyo ezi zinto ziya kufakwa phantsi.

Inkqubo yokuphucula i-weltils esetyenziswa kwi-ASTM A139 inika umbhobho ongaphezulu nangaphezulu, obaluleke kakhulu ekuqinisekiseni ukuhamba okusebenzayo kwegesi yendalo ngombhobho wendalo ngombhobho wendalo ngombhobho wendalo ngombhobho wendalo ngombhobho wendalo ngombhobho wendalo ngombhobho wendalo ngombhobho. Le mibhobho iyafumaneka kwiidayimitha ezahlukeneyo kunye nobubanzi bomhlaba, zivumela ukuguquguquka kuyilo kunye nolwakhiwo lokuhlangabezana neemfuno ezithile zosulelo lwegesi yendalo okanye inkqubo yokuhambisa.

Ukongeza ekuthembekeni kunye nokuqina, i-ASTM ye-A139 ibonelela ngokungakhathali, ekubaluleke kakhulu ekuqinisekiseni ingqibelelo yexesha elide yemibhobho yegesi yendalo engaphantsi komhlaba. Isixhobo se-carbon yentsimbi esisetyenzisiweyo kule mibhobho senzelwe ngokukhethekileyo ukuxhathisa i-comrosion, ukuqinisekisa ukuba imibhobho ihlale ivakala ngokuvakalayo kwaye ivuza-simahla iminyaka ezayo.

Ukukhuseleka kubaluleke kakhulu ekwakhiweni kwemibhobho yegesi yendalo engaphantsi komhlaba. I-ASTM i-A139 imibhobho yenziwa kwaye ivavanyelwe kwimigangatho engqongqo yeshishini kunye neenkcazo, ukuqinisekisa ukuba banokumelana nemiceli mingeni engaphantsi komhlaba. Oku kunika izinto zerhasi yendalo, ooguli kunye noxolo lwengqondo lokwazi ukuba iziseko zophuhliso ezihambisa irhasi yendalo ithembekile kwaye ikhuselekile.

Ukuqukumbela, i-ASTM A139I-Spil Welbon ye-SPOND PAEL PAELIdlala indima ebalulekileyo ekwakhiweni kwemibhobho yegesi engaphantsi komhlaba. Ukuqina kwabo, ukuxhathisa kwabo, ukuxhathisa kwabo kunye nokuhambelana nemigangatho yeshishini kwenza ukuba balungele iiprojekthi zezibonelelo ezibalulekileyo ezinje. Xa kufikwa kuqinisekisa ukhuseleko, ukuthembeka kunye nokusebenza kakuhle kokuhanjiswa kwegesi yendalo kunye neenkqubo zokuhambisa, kusetyenziswa i-ASTM A139 piholine sisigqibo esingenakutyeshelwa. Ngokukhetha izixhobo ezifanelekileyo kwezi zicelo ziphantsi komhlaba, sinokuqinisekisa ukuba iziseko zophuhliso zegesi zendalo zihlala zikhuselekile kwaye zithembekile kwizizukulwana ezizayo.

Ngaphambili: Ukubaluleka kwe-tubular yentsimbi yentsimbi yolwakhiwo lomgca wamanzi aphantsi komhlaba

Okulandelayo: Ukubaluleka kwemiphetho ye-wellded kabini kunye ne-polyurethane imibhobho enemibhobho ye-pipe
