1. Ipayipi lensimbi eliwugqinsiukusika: Ngokuhambisana nobude bangempela bepayipi obudingekayo, ipayipi kufanele lisikwe ngesaha lensimbi noma isaha elingenamazinyo. Lapho i-welding yamanzi isetshenziselwa inqubo yokusika, izinto zokusetshenziswa kufanele zivikelwe ngokufanele. Lapho usika, izinto ezikwazi ukumelana nomlilo nezimelana nokushisa kufanele zisetshenziswe njengama-baffles emikhawulweni emibili yokuphuka ukuze kubanjwe izinhlansi nensimbi encibilikisiwe eshisayo ewa ngesikhathi sokusika ukuze kuvikelwe izinto ezingavuthiwe. Isendlalelo sokuqala sepulasitiki.

2. Ukuxhunywa kwepayipi lensimbi eliwugqinsi: Ngemva kokuba ukulungiswa kwepulasitiki sekuqediwe, xhuma ipayipi nezinsimbi zamapayipi bese ufaka amaphedi enjoloba phakathi kwama-flange ngesikhathi sokuxhuma, futhi uqinise amabhawodi esimweni esivaliwe.

3. Ipayipi lensimbi elinezindonga eziwugqinsi ukwelapha okokugcotshwa kwepulasitiki: Ngemva kokupholishwa, sebenzisa umoya-mpilo kanye ne-C2H2 ukushisa umlomo wepayipi ngaphandle kwepayipi kuze kuncibilike ungqimba lwepulasitiki lwangaphakathi, bese isisebenzi esinekhono sizofaka ngokulinganayo impushana yepulasitiki elungisiwe emlonyeni wepayipi. , Kufanele inake ngokuhambisanayo okufanele igcotshwe endaweni, futhi ipuleti le-flange kufanele ligcotshwe ngaphezu komugqa wokumisa amanzi. Kule nqubo, izinga lokushisa lokushisa kufanele lilawulwe ngokuqinile. Uma izinga lokushisa liphezulu kakhulu, amabhamuza azokhiqizwa ngesikhathi senqubo yokumboza ngepulasitiki. Uma izinga lokushisa liphansi kakhulu, I-powder yepulasitiki ngeke incibilike ngesikhathi senqubo yokumboza ipulasitiki. Lezi zimo ezingenhla zizokhiqiza ipulasitiki ngemva kokusetshenziswa kwepayipi. Ngokwenzeka kokuchithwa kwezingqimba, ingxenye yepayipi yensimbi enodonga oluwugqinsi yonakele futhi yonakaliswa esigabeni sakamuva.

4. Ukugaya umlomo wepayipi lensimbi eliwugqinsi: Ngemva kokusika, umshini wokugaya i-engeli kufanele usetshenziselwe ukugaya ungqimba lwepulasitiki lomlomo wepayipi. Inhloso ukugwema ukuncibilika noma ukushisa ungqimba lwepulasitiki ngesikhathi se-flange welding futhi ucekela phansi ipayipi. Sebenzisa i-engeli grinder ukupholisha ungqimba lwepulasitiki lombhobho.

passivity ukwakha ifilimu zokuzivikela phezu. Amapayipi ensimbi anezindonga eziwugqinsi anokuqina okuphezulu, ukukwazi ukusebenza kahle, ukuguquguquka okubandayo kwepulasitiki okumaphakathi, kanye nokushisela; futhi, ukuqina kwensimbi akwehliswa kakhulu ngesikhathi sokwelashwa kokushisa, kodwa inamandla aphakeme kakhulu futhi igqoka ukumelana, ikakhulukazi lapho amanzi ecishiwe. Inokuqina okuphezulu; kodwa le nsimbi izwela kakhulu ezindaweni ezimhlophe, inomkhuba wokuthukuthela kanye nokuzwela ukushisa ngokweqile ngesikhathi sokwelashwa kokushisa, inamandla amakhulu nokuqina, ukuqina okuhle, ukuguqulwa okuncane ngesikhathi sokucisha, namandla aphezulu okukhasa emazingeni okushisa aphezulu Kanye namandla esikhathi eside. Isetshenziselwa ukwenza ama-forging adinga amandla aphakeme kunensimbi engu-35CrMo kanye nengxenye enkulu ecishiwe futhi epholile, njengamagiya amakhulu okudonsa kwesitimela, amagiya okudlulisa ama-supercharger, ama-ekseli angemuva, izinduku zokuxhuma nezinsimbi zasentwasahlobo ezilayishwe kakhulu. Ingasetshenziswa futhi ukubhoboza amapayipi kanye namathuluzi okudoba emithonjeni ejulile kawoyela engaphansi kuka-2000m futhi ingasetshenziswa njengesikhunta semishini yokugoba.
