Amathemba okuthuthukiswa kwemakethe yamapayipi ensimbi omthungo amakhulu abanzi

Ngokuvamile, sibiza amapayipi ashiselwe ngeminwe anobubanzi obungaphandle obungaphezu kuka-500mm noma ngaphezulu njengamapayipi ensimbi anomugqa oqondile wobubanzi obukhulu. Amapayipi ensimbi anomugqa oqondile anobubanzi obukhulu ayisinqumo esingcono kakhulu samaphrojekthi wamapayipi amakhulu, amaphrojekthi okuhambisa amanzi negesi, nokwakhiwa kwenethiwekhi yamapayipi asemadolobheni. Ngamanye amazwi, amapayipi ensimbi anobubanzi obukhulu obuqondile anomthungo anobubanzi obukhudlwana kanye nemikhawulo emincane (ubukhulu obukhona manje bobukhulu bamapayipi ensimbi angenamthungo ngu-1020mm, ububanzi obukhulu bamapayipi ensimbi ane-weld kabili bungafinyelela ku-2020mm, kanti ububanzi bobukhulu be-single- ama-weld seams angafinyelela ku-1420mm), inqubo elula kanye nentengo ephansi. nezinye izinzuzo zisetshenziswa kabanzi.

Amapayipi ensimbi anezinhlangothi ezimbili angaphansi kwamanzi ashiselwe i-arc eqondile nawo angamapayipi ensimbi omthungo oqondile. I-arc engaphansi eshiselwe ipayipi lensimbi yomthungo eqondile yamukela inqubo ebandayo ye-JCOE, i-welding seam ithatha intambo yokushisela, futhi i-arc welding engaphansi kwamanzi ithatha i-particle flux. Inqubo eyinhloko yokukhiqiza ye-arc efakwe emanzini eshiselwe ipayipi lensimbi yomthungo eqondile iyavumelana nezimo, futhi ingakhiqiza noma yikuphi ukucaciswa, okuhlangabezana kakhulu nezidingo zomhlaba wonke zosayizi wepayipi lensimbi, kuyilapho ukukhiqizwa okujwayelekile kwasekhaya kuvame ukusebenzisa ipayipi lensimbi lomthungo ophezulu.

Ngokuthuthuka komnotho wezwe, isidingo samandla sikhule kakhulu. Emashumini eminyaka azayo noma ngisho namashumi, kubalulekile ukuthuthukisa ubuchwepheshe nokwakha iphrojekthi.
