Izinqwaba zamapayipi ezishiselwe i-arc ezishiselwe ikhwalithi ephezulu zifika e-Australia

Muva nje, inani elikhuluizinqwaba zamapayipi ezishiselwe i-arc longitudinal ngaphansi kwamanzizithunyelwe e-Australia, i-Botop Steel inikeza ikhwalithi ephezuluS275 JRH amapayipi enqwaba yesakhiwoezweni.Njengomkhiqizi ohamba phambili wamapayipi ashiselwe i-arc angaphansi kwamanzi angaphansi kwe-arc e-China silindeleke kakhulu kumaphrojekthi wokwakha kanye nokuthuthukiswa kwengqalasizinda e-Australia.

Ipayipi le-LSAW (Longitudinal Submerged Arc Welded) laziwa ngamandla akhethekile nokuqina, okulenza libe lilungele ukusetshenziswa kokunqwabelanisa kwesakhiwo.Inqubo ye-welding engenamthungo esetshenziswa ekukhiqizeni la mapayipi iqinisekisa izinga eliphezulu lokunemba nokuvumelana, okuholela kumapayipi ahlangabezana nezindinganiso eziphakeme kakhulu.

Isinqumo sokungenisa izinqwaba zamapayipi ashiselwe i-arc longitudinal angaphansi kwamanzi asuka eShayina sasisekelwe esithunzini somkhiqizi njengomhlinzeki onokwethenjelwa futhi osungula amapayipi ensimbi.Izikhungo zokukhiqiza zale nkampani ezisezingeni eliphezulu zihlome ngobuchwepheshe bakamuva, obuzivumela ukuthi zikhiqize amapayipi angewona nje awezinga eliphezulu kuphela kodwa futhi asimeme imvelo.

Ipayipi le-S275 JRH, ikakhulukazi, idingeka kakhulu ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, eziyenza ifanelekele uhla olubanzi lwezicelo ezihlanganisa ukwakhiwa kwamabhuloho, isisekelo sezakhiwo kanye nemiklamo yengqalasizinda yasolwandle.Umthamo wabo omkhulu wokuthwala umthwalo kanye nokumelana nokugqwala kuwenza alungele izindawo ezinokhahlo.

I-arc engaphansi ye-longitudinalinqwaba yamapayipi ashiselwesebefikile e-Australia ngesasasa elikhulu lezinkampani zokwakha kanye nabathuthukisi abadinga ikhwalithi ephezuluamapayipi enqwaba yesakhiwo.Ukutholakala kwala mapayipi akugcini nje ngokunikela empumelelweni yamaphrojekthi aqhubekayo kodwa futhi kuvula indlela yamathuba amasha nentuthuko embonini yezokwakha yase-Australia.

Njengesidingo se-arc engaphansi kwe-longitudinalipayipi elishiselweama-piles ayaqhubeka nokukhula, umkhiqizi waseShayina uzibophezele ekuhlangabezaneni nesidingo samakhasimende ngokuqinisekisa ukulethwa okufika ngesikhathi nangempumelelo e-Australia.Ukuzibophezela kwabo ekwanelisekeni kwamakhasimende kanye nokwenza kahle komkhiqizo kuqinise isikhundla sabo njengomphakeli othembekile weAmapayipi ensimbi e-LSAWemakethe yamazwe ngamazwe.

Kafushane, ukufika kweIzinqwaba zamapayipi e-LSAWe-Australia kuphawula ingqophamlando ebalulekile embonini yezwe yezokwakha kanye nokuthuthukiswa kwengqalasizinda.Izinga nokuthembeka kwala mapayipi, kuhambisana nokuzibophezela komkhiqizi ekwenzeni okuhle, ngokuqinisekile kuzoba nomthelela omuhle embonini futhi kusize ekuqhubekiseleni phambili inqubekelaphambili kanye nokuqanjwa okusha iminyaka eminingi ezayo.
