Kwimihla yakudala, kungcono ukuyisebenzisa kwiGas PipeUmbhobho omnyamaOku kwakubangelwa kakhulu kukungalungelani komgangatho wokusebenzisa i-galvanizing.Namhlanjeumbhobho we-galvanizedakusavumelekanga ukusetyenziswa kwigesi yendalo.Ukuqhekeka kwe-galvanizing ngaphakathi kombhobho kwabangelwa zezinye iigesi ezifana negesi ye-coal tar eyayiyi-"gesi eyenziweyo" engeyiyo yendalo. "Ipayipi yentsimbi kufuneka ibe yiShedyuli 40 okanye ibe nzima, kufuneka ihambelane nomnye wemigangatho edwelisiweyo kwaye inokuba yintsimbi emnyama okanye i-galvanized. Ngokuchasene nenkolelo eqhelekileyo, igesi yendalo ayichaphazeli kakubi i-zinc coating kumbhobho we-galvanized". Ulwimi olufanayo lukwasetyenziswa kuHlelo luka-2006 kwiKhowudi kunye neNgxelo ye-IFGC (International Fuel Gas Code). Abalungisi bemibhobho badla ngokusebenzisa umbhobho omnyama onegesi ngezizathu ezibini eziphambili. Esinye kukuba ixabisa ngaphantsi kune-galvanized. Esinye kukuba ukuba imibhobho ye-galvanized isetyenziselwa amanzi, ukusebenzisa umnyama njengegesi kwahlula ukusetyenziswa okubini. Ingcebiso elungileyo ukuba usebenzisa umbhobho omnyama wesinyithi wegesi ngaphandle kwesakhiwo kukupeyinta umthubi ukuthintela imicu yokugqwala. Kuxhomekeke kwiprojekthi yokwakha.
Umahluko Phakathi Kombhobho Omnyama kunye Nombhobho Ogayiweyo
Amanzi negesi zifuna iipayipi ukuze zibonelele ngezindlu zokuhlala kunye namashishini. Igesi inika umbane kwizitovu, izifudumezi zamanzi, ii-oven kunye nezinye izixhobo. Amanzi abalulekile kwaye acacile. Iintlobo ezimbini eziqhelekileyo zepayipi yentsimbi esetyenziselwa ukuthwala amanzi kunye negesi yipayipi emnyama kunye nepayipi ye-galvanized. Ngoko ke, yintoni umahluko phakathi kwepayipi emnyama kunye nepayipi ye-galvanized.
*Iipayipi zentsimbi eziqinisiweyo
Umbhobho wentsimbi egayiweyo ugqunywe ngezinto ze-zinc ukwenza umbhobho wentsimbi umelane ngakumbi nokugqwala. Eyona ndlela iphambili yokusebenzisa umbhobho ogayiweyo kukubonelela ngamanzi. I-zinc ikwathintela ukuqokelelana kweeminerali ezinokuvala umgca wamanzi.
*Iipayipi zeNtsimbi emnyama
Umbhobho wentsimbi emnyama wahlukile kumbhobho we-galvanized kuba awugqunywanga. Umbala omnyama uvela kwi-iron-oxide eyenziwe kumphezulu wayo ngexesha lokwenziwa. Injongo ephambili yombhobho wentsimbi emnyama kukuthwala igesi yendalo emakhaya nakwiishishini. Umbhobho omnyama ongenamthungo wenziwa ngaphandle komthungo, nto leyo eyenza ukuba ube ngumbhobho oqinileyo nokhuselekileyo wokuthwala igesi. Umbhobho wentsimbi omnyama ogqunyiweyo ukwasetyenziselwa iinkqubo zokutshiza umlilo.
