Ubudlelwane bokuthuthukisa izitayela zokubulala eziphumelelayo

Kangangoku, izindawo zemigqa zisetshenziswa ngokubanzi ekuthuthukiseni nezimali. Izinhlobo zemigqa ezisetshenziswayo ekuthuthukiseni nezimali ngokude kuzifaka i-spiral submerged arc welded steel pipes nezinhlobo zemigqa eziphansi kwezinhlobo zemigqa engqikithwe yamagama. Ngoba i-spiral submerged arc welded pipe iyinhlobo enguqu ngamagama amabi nezindleke zokubanda kuyizinhlobo, ukuthuthukiswa kwezinhlobo kuyizinhlobo zokubanda kwenzelwa ngokubanda kwezinhlobo. Ngaphezulu koko, kukhona amaphawu amaningi aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu aye amakhulu a......

Kamuva, iChina iyasiza ukupheliswa kweyoli ne-gas eNtshona kweNingizimu. Ngokupheliswa kweyoli kwezindawo eziningi zasekhanda, ipayiphi evela kumhlaba onke iyaphakelwa ngamandla okugcina, amandla okulungisa neyokubendula, futhi isimo sekuhlukahluka sikhona, lokhu yindlela ephansi yesayiphelo seyoli esibekwe ngokuxhunyiwe. Ukuze kuthuthukwe amandla okuthutha kweyoli futhi kuhlinzekwe ukupheliswa kweyoli esikhundleni esingcono, ipayiphi esikhundleni kakhulu isebenzisa isayiphelo seyoli esibekwe ngokuphambene. Ngakho, kunoma isayiphelo seyoli esibekwe ngokuxhunyiwe, isayiphelo seyoli esibekwe ngokuphambene sinemisindo encane neyokulungisa, ngakho ngokusho senjongo le, isayiphelo seyoli esibekwe ngokuphambene siyisikhetha esiyagcina.

Imithombo, ukudaleka, ubushishini bokudla nezinye iindustri zidinga iipipi ezinkanye zokudanjwa. Okwangoku, ipipo langaphakathi yevalve seat ikhutshelwa emva kokudanjwa kwenxenye yemachini, oku kuthatha kakhulu amandla, ixesha nezinto zokudla. Ukuba iipipi ezinkanye zokudanjwa eziphakathi ziphathwa, kuba yindlela engeke iyahlakane. Ngokufanayo, ngokuba kudinga ukuba iindlela zokugqibela zibe nendlela yokugqibela, kuphela iipipi ezinkanye zokudanjwa zisetshenziswa kwiipipi zezakhiwo; Izipi ezinkanye zokudanjwa zasebenzisa kwiipipi zokudla.
