Ukunemba kwedayamitha yangaphandle yezindonga eziwugqinsiipayipi elingunxandekunqunywa umuntu, futhi umphumela uncike kukhasimende.Kuya ngezidingo zekhasimende zobubanzi obungaphandle beipayipi elingenamthungo, ukusebenza nokunemba kweipayipi lensimbiimishini yokulinganisa, kanye nesistimu yokulinganisa ipayipi lensimbi.
Indlela yokulinganisa yepayipi elingenamthungo iyisici esibalulekile sokunquma ukubekezelelana kobubanzi bangaphandle bepayipi lensimbi.Ukunemba kwedayamitha yangaphandle yeamapayipi ayisikwele anezindonga ezinkulunge-longitudinal rolling sizing ingafinyelela cishe ku-1%, kuyilapho ukunemba kobubanzi bangaphandle bamapayipi angenamthungo anokulinganisa okugoqayo angafinyelela ku-0.5%.
Ithonya lesistimu yezobuchwepheshe ekunembeni kobubanzi obungaphandle bepayipi lensimbi ngokuyinhloko lincike ekushiseni okuguquguqukayo nokuzinza kwezinga lokushisa lomshini wokulinganisa wepayipi lensimbi.Izinga lokushisa rolling of steel pipe liphezulu, kanye nokunciphaipayipi eliyisikwele eliwugqinsingemva kokugoqa kukhulu, okuvame kulula ukudlula ububanzi obungaphandle ukukhiqiza ukuphambuka okungalungile kwepayipi lensimbi;Ngokuphambene nalokho, izinga lokushisa eliphansi lokugoqa lingase lidlule ukuchezuka okuhle futhi libe umkhiqizo onesici.Ngakho-ke, umshini wokugaya ipayipi lensimbi kufanele ulungiswe ngokuqhubekayo ngokuya ngokucaciswa kosayizi, ibanga lepayipi lensimbi, isimo sokushisa kanye nesimo sokugqoka kwamathuluzi sepayipi lesikwele esiwugqinsi.
Enqubweni yokuthuthukiswa kwezimboni ngokushesha, ingxenye yamashubhu ayisikwele anezindonga eziwugqinsi ekuphumeni kwensimbi yaseChina iyanda.Ngenxa yokusetshenziswa okubanzi kwepayipi eliyisikwele sodonga oluwugqinsi, izidingo eziphakeme zibekwe phambili ngekhwalithi yayo.Phakathi kwabo, ukuchezuka ukushuba odongeni of aminyene izindongaamashubhu squareingenye yezinkomba ezibalulekile zekhwalithi yazo, ngoba ukuchezuka kokuqina kodonga kuzothinta ngqo uhla lokusebenzisa amashubhu ayisikwele anezindonga eziwugqinsi.Emqhudelwaneni wamanje wemakethe oshubile, uma umkhiqizi wamashubhu ayisikwele anezindonga eziwugqinsi engakwazi ukusebenza kanzima ngekhwalithi futhi engakwazi ukukhiqiza amashubhu ayisikwele anezindonga eziwugqinsi wekhwalithi ephezulu, akunakugwemeka ukuthi amasheya amaningi emakethe azolahleka.
Emashumini eminyaka emizamo eqhubekayo nokuzijwayeza, kanye nenani elikhulu lokushintshana kwezobuchwepheshe kanye nezinguquko ezingokoqobo zokusebenza nabakhiqizi abathile abanamandla, abaningi.ishubhu eliyisikwele elinezindonga eliwugqinsiabakhiqizi baye bathuthukisa kakhulu ukuphambuka kokuqina kodonga lwamashubhu ayisikwele anezindonga.
Ake sikhulume ngezinkinga ezithile zodonga oluwugqinsiamashubhu squareenqubweni yangempela yokukhiqiza: ukuchezuka okukhiqizwa enqubweni yokubhoboza yombhobozi, ukunemba kokukhiqizwa kwemishini kanye nesakhiwo, ukufakwa nokulungiswa komugqa wemishini, inqubo yokushisa yeshubhu elingenalutho, ukuvaleka kweshubhu elingenalutho, umthelela. yokunemba kwamathuluzi, kanye nokusetshenziswa komshini wokugoqa amashubhu othomathikhi.
