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, inokukhiqiza okuphezulu, 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 i-arc welding enezinhlangothi 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.

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.
