X60 Spiral Submerged Arc Welded Line Pipe For Oil Pipelines

Incazelo emfushane:

Isidingo sikawoyela negesi yemvelo siyaqhubeka sikhula, futhi kuhambisana nesidingo samapayipi asebenza kahle nathembekile.Lapha yilapho ipayipi lomugqa we-X60 SSAW liqala ukusebenza.Lolu hlobo lwamapayipi ensimbi okuvunguza luyisinqumo esidumile ekwakhiweni kwepayipi likawoyela futhi lunikeza uhla lwezinzuzo ezikwenza kube yisixazululo esifanelekile sokuthuthwa kukawoyela negesi.

Omaka bomkhiqizo

Ipayipi likalayini we-X60 SSAW, elaziwa nangokuthi yipayipi lepayipi elishiselwe i-arc elishiselwe ku-spiral, lisebenzisa amakhoyili ensimbi aginqike ashisayo njengempahla eluhlaza ukuze agobe umucu ube amapayipi.Le nqubo yokukhiqiza yenza ipayipi ingabi namandla futhi ihlale isikhathi eside, kodwa futhi imelana kakhulu nokugqwala nokucindezeleka.Lezi zimfanelo zibalulekileipayipi lamafutha imigqa, ezivame ukuba ngaphansi kwezimo ezinzima zemvelo kanye nezimo ezicindezelayo.

Ukuhlolwa kwe-Hydrostatic

Enye yezinzuzo eziyinhloko zeX60Ipayipi lomugqa we-SSAWamandla alo aphezulu.Leli payipi linamandla amancane okukhiqiza angu-60,000 psi, okwenza lilungele izidingo zokucindezela okuphezulu kokuthuthwa kukawoyela negesi.Inqubo ye-welding ye-spiral iphinde iqinisekise ukuthi ipayipi inobukhulu obufanayo bodonga, okwandisa amandla ayo nokuthembeka.

Ngaphezu kwamandla, ipayipi likalayini we-X60 SSAW laziwa ngokudubeka kwawo okuhle kakhulu kanye nokuqina komthelela.Lokhu kusho ukuthi ipayipi liyakwazi ukumelana nezingcindezi kanye nobunzima bokuhamba nokufakwa ngaphandle kokubeka engcupheni ubuqotho balo.Lokhu kubaluleke kakhulu emigqeni yamapayipi kawoyela, ngokuvamile adinga ukunqamula indawo eyinselele futhi anqobe izithiyo ezihlukahlukene ngesikhathi sokwakhiwa.

Ukwengeza, ipayipi likalayini we-X60 SSAW liyamelana nokugqwala, okulenza libe yisixazululo esihlala isikhathi eside futhi esingabizi kakhulu emigqeni yamapayipi kawoyela.Inqubo yokushisela okuvunguzayo idala indawo ebushelelezi kanye nokushisela okungaguquki, kunciphisa ingozi yokugqwala nokwelula ukuphila kwepayipi.Lokhu kubalulekile emafutheniiphayiphis, ezichayeka ezintweni ezonakalisayo nezici zemvelo ezingehlisa isithunzi sezinto ezisezingeni eliphansi.

Ekwakhiweni kwamapayipi kawoyela, ukuphepha nokwethembeka kubaluleke kakhulu.Ipayipi likalayini we-X60 SSAW limaka wonke amabhokisi lapha, lihlinzeka ngesixazululo esiqinile, esiqinile futhi esimelana nokugqwala esingamelana nobunzima bokuthuthwa kukawoyela negesi.Amandla ayo aphezulu, i-ductility enhle kakhulu kanye nokuqina komthelela kuyenza ibe ukukhetha okuthembekile kumaphrojekthi wamapayipi ayinselele kakhulu.

Kafushane, ipayipi likalayini we-X60 SSAW liwukhetho lokuqala lwamapayipi kawoyela ngenxa yamandla alo aphakeme, ukuqina kanye nokungagqwali kwawo.Inqubo yayo yokushisela i-spiral ikhiqiza amapayipi angakwazi ukumelana nokucindezela okuphezulu, indawo eyinselele nezindawo ezigqwalile, okuwenza abe yisixazululo esinokwethenjelwa nesingabizi kakhulu sokuthuthwa kukawoyela negesi.Lapho kwakhiwa amapayipi kawoyela, ukukhetha ipayipi lepayipi elishiselwe i-arc elingu-X60 kuyisinqumo sokuqinisekisa ukuphepha nokuthembeka kwawo wonke umsebenzi.
