Amapayipi Esakhiwo Anezingxenye Ezingenalutho Nendima Yawo Kwingqalasizinda Yamapayipi Kawoyela

Amapayipi Esakhiwo Anezingxenye Ezingenalutho Nendima Yawo Engqalasizinda Yepayipi Likawoyela Isithombe Esifakiwe

Incazelo emfushane:

Ukwakhiwa kwepayipi likawoyela Amanethiwekhi omugqa adinga izinto eziqinile nezithembekile ezingamelana nokucindezeleka okuphezulu, izimo zezulu ezimbi kakhulu kanye nezimo ezinzima. Enye yezinto ezinjalo ipayipi lesakhiwo eliyi-hollow section, ikakhulukazi i-submerged arc welded (SAW) variant (eyaziwa nangokuthi ipayipi le-SSAW). Kulesi sihloko sebhulogi, sizohlola ukubaluleka kwamapayipi esakhiwo ayisi-hollow section engqalasizinda yamapayipi kawoyela kanye nezinzuzo zawo ezahlukahlukene.

Funda ngamapayipi esakhiwo angenazo izimbobo:

Imbobo-amapayipi esakhiwo sesigaba, okuhlanganisa amapayipi e-arc welded arc ac welded ac welded arc, asetshenziswa kabanzi embonini kawoyela negesi ngenxa yamandla awo aphezulu kanye nokuqina kwawo. Lawa mapayipi akhiqizwa kusetshenziswa ubuchwepheshe be-arc welding ac welded ac welded, lapho kwakheka khona i-arc welding ngaphansi kwengqimba ejiyile ye-granular flux. Le nqubo iqinisekisa ukuthi umthungo we-weld oncibilikisiwe kanye nezinto eziyisisekelo zivikelwe ekungcoleni komoya, okuholela esakhiweni sepayipi esingenamthungo nesiqinile.

Indima yamapayipi esakhiwo angenalutho emigqeni yamapayipi kawoyela:

1. Thuthukisa ukuzinza kwesakhiwo: Amapayipi esakhiwo anezingxenye ezingenalutho anokumelana okuphezulu kokugoba futhi afaneleka kakhulu ebangeni elideipayipiezokuthutha. Ukwakhiwa kwayo okuqinile kwenza ukugeleza kube lula futhi kunciphisa ingozi yokuvuza, okuqinisekisa ubuqotho bohlelo lwepayipi likawoyela.

2. Ukuvikelwa Kokugqwala: Imboni kaphethiloli ivame ukudalula amapayipi ezintweni ezigqwala zangaphakathi nezangaphandle. Amapayipi esakhiwo anezingxenye eziyimbobo angambozwa ngezinto ezingagqwali ukuze ahlinzeke ngesivikelo esihlala isikhathi eside ekugqwaleni, amakhemikhali nezinye izinto eziwohlokayo. Lokhu kuvumela amapayipi kaphethiloli ukuthi asebenze kahle isikhathi eside.

3. Ukuguquguquka ekuzivumelaniseni nendawo:Ipayipi likawoyela umugqaImizila ivame ukudabula indawo eyinkimbinkimbi, okuhlanganisa izintaba, izigodi, kanye nezithiyo ezingaphansi kwamanzi. Amapayipi esakhiwo anezingxenye ezingenalutho aklanywe ngobubanzi obuhlukahlukene kanye nobukhulu bodonga, okuvumela ukuguquguquka kokuzivumelanisa nezindawo ezihlukahlukene ngaphandle kokubeka engcupheni ubuqotho besakhiwo. Angamelana ngempumelelo nengcindezi yangaphandle kanye nokucindezeleka kwe-geological, okuqinisekisa ukuphepha nokuthembeka kohlelo lokuthuthwa kukawoyela.

4. Ukusebenza Kahle Ngezindleko: Amapayipi esakhiwo anezingxenye eziyimbobo ngokuvamile asebenza kahle kakhulu kunezinye izinketho zamapayipi njengepayipi lensimbi eliqinile ngenxa yokusebenza kahle kwezinto zokwakha. Inqubo yokushisela ivumela ukudalwa kwamapayipi amakhulu anobubanzi, ngaleyo ndlela kunciphisa isidingo sokuxhumeka okunamandla kakhulu kwamalunga. Ngaphezu kwalokho, isilinganiso sawo samandla nesisindo siqinisekisa ukusetshenziswa kahle kwezinto zokwakha futhi kunciphisa izindleko zokuhamba.

5. Ukulula kokugcinwa nokulungiswa: Amapayipi esakhiwo anezingxenye ezingenalutho avame ukuklanywa ngokucabangela ukulungiswa nokulungiswa okulula. Uma kwenzeka umonakalo noma ukuguguleka, amapayipi ngamanye angashintshwa ngaphandle kwesidingo sokudiliza lonke ipayipi kakhulu. Le ndlela inciphisa isikhathi sokungasebenzi futhi inciphise izindleko zokulungisa, iqinisekisa ukugeleza kukawoyela okuqhubekayo.

Ekuphetheni:

Amapayipi esakhiwo anezingxenye ezingenalutho, ikakhulukaziI-SSAWamapayipi, idlala indima ebalulekile ekwakheni amanethiwekhi emigqa yamapayipi kawoyela aqinile futhi asebenzayo. Lawa mapayipi abe yisinqumo esikhethwayo embonini kawoyela negesi ngenxa yokuqina kwawo kwesakhiwo okuthuthukisiwe, ukuvikelwa kokugqwala, ukuzivumelanisa nezimo ezindaweni ezahlukene, ukusebenza kahle kwezindleko kanye nokulula kokugcinwa. Indima ebalulekile abayidlalayo ekuqinisekiseni ukuthuthwa kukawoyela okuphephile nokuthembekile ayinakukhushulwa ngokweqile. Ukuthuthukiswa okuqhubekayo kanye nokusetshenziswa kwamapayipi esakhiwo anephrofayili engenalutho kuzothuthukisa kakhulu ingqalasizinda yemigqa yamapayipi kawoyela ukuze kuhlangatshezwane nezidingo zamandla ezikhulayo zomhlaba wanamuhla.

Okwedlule: Ukuthuthukisa Ingqalasizinda Yegesi Yemvelo Ngeshubhu Ehlanganisiwe Elikhulu: Izinzuzo Zamapayipi Ensimbi Ejikelezayo e-S235 J0

Olandelayo: Amapayipi Ahlanganisiwe Anobubanzi Obukhulu Amapayipi Ensimbi Ane-Tubular
