Umthungo oqondile onezinhlangothi ezimbili ezishiselwe ipayipi le-arc elishiselweIpayipi le-JCOE.Ipayipi lensimbi lomthungo oqondile lihlukaniswa ngezinhlobo ezimbili ngokusekelwe kwinqubo yokukhiqiza: ipayipi lensimbi lomthungo eliphakeme imvamisa ephezulu kanye ne-arc engaphansi eshiselwe ipayipi lensimbi lomthungo eliqondile i-JCOE.Amapayipi ensimbi afakwe ngaphansi kwe-arc ashiselwe oqondile ahlukaniswa njenge-UOE, RBE, JCOE,Amapayipi ensimbi e-LSAW, nokunye okusekelwe ezindleleni zabo zokwakha.Inqubo yokukhiqiza ipayipi le-JCOE iqondile, isebenza kahle kakhulu ekukhiqizeni, izindleko eziphansi, kanye nentuthuko esheshayo.
Ipayipi le-JCOE lingenye yezindlela zokwenza ipayipi lensimbi lomthungo oqondile, kanye nenye yemishini.E-China, i-GB/T3091-2008 kanye ne-GB/T9711.1-2008 zisetshenziswa kakhulu, kuyilapho i-API-5L iyindinganiso yamazwe ngamazwe.Ipayipi le-JCOE lakhiwe ngokuyinhloko kusetshenziswa ukushiselwa kwe-arc okunezinhlangothi ezimbili.Ukuze kuhlangatshezwane nezidingo zamazinga afanelekile, imikhiqizo ihamba ngezinqubo eziningi ezifana nokugoba, ukuhlanganisa, ukushisela kwangaphakathi, ukushisela kwangaphandle, ukuqondisa, kanye neziphetho eziyisicaba.
Amaphrojekthi amakhulu wamapayipi, amaphrojekthi okuhanjiswa kwamanzi negesi, ukwakhiwa kwenethiwekhi yamapayipi asemadolobheni, izakhiwo zesakhiwo sensimbi, ukunqwabelana kwamabhuloho, ukwakhiwa kukamasipala, nokwakhiwa kwedolobha konke kusebenzisa ipayipi le-JCOE.
Ifomula yesisindo: [(ukujiya kodonga lwangaphandle)*ukujiya kodonga]*0.02466=kg/m (isisindo imitha).

Akukho ukugoqeka, ukuqhekeka, i-delamination, i-lap welding, ukuphuka kwe-arc, ukushiswa, noma ezinye izinkinga zasendaweni okujula kwazo kudlula ukuchezuka okuphansi kokuqina kodonga kuvunyelwe endaweni engaphakathi nangaphandle yamapayipi ensimbi yomthungo oqondile we-JCOE.Okunye okungalungile kwasendaweni okunokujula okungeqi ukuchezuka okuphansi kokuqina kodonga kuvunyelwe.
i-yuantai pipe millinomugqa wokukhiqiza wepayipi we-JCOE ongu-1.
I-Yuantai tube millingakhiqiza amapayipi ensimbi e-LSAW, OD :355.6-1420mm, ukujiya: 21.3-50mm, ubude: 1-24M.i-yuantai hollow section millingaphinda ikhiqize isigaba esingenalutho esiyisikwele OD:10*10-1000*1000mm isigaba esingenalutho esingunxande OD:10*15-800*1100mm,ugqinsi:0.5-60mm,ubude:0.5-24M.Kulo nyaka,iqembu le-yuantai derun lithole isitifiketi se-DNV ,ipayipi yensimbi ye-yuantai yokwakha umkhumbiIzohlinzekwa ngezinga elikhulu,amashubhu ensimbi we-yuantai wokwakha umkhumbizishintshwa zisuka kumapayipi ensimbi e-JCOE
