Spiral welded simbi mapaipi ese anotora yakanyura arc welding process, yakatwasuka musono wakaiswa welded pombi dzesimbi dzakanyura pasi arc dzakasungirirwa dzakatwasuka musono pombi dzesimbi dzepfupi UOE, uye yakatwasuka seam yakakwirira-frequency kuramba welding yepfupi ERW.
Kana ichienzaniswa neyakanyura arc welding, iyo yakakwira-frequency kuramba yakashongedzwa nesimbi pombi (ERW simbi pombi) haiwedzeri chero zvinhu zvewelding panguva yewelding process.Naizvozvo, iyo yakaumbwa weld inonyatso kuenderana nekemikari yesimbi yepasi.Mushure mekunge pombi yesimbi yakashongedzwa, inonamirwa kuti iite kushushikana kwemukati kwekushanda kunotonhora, uye kushushikana kwemukati kwewelding kunovandudzwa, saka iyo yakazara mechanical properties yeERW steel pipe iri nani.Asi parizvino, vagadziri vanomiririrwa neShanghai Ellison neGuangdong Panyu Zhujiang Steel Pipe Factory vanongoburitsa mapaipi pazasi φ355mm, uye mapaipi egasi makuru-diameter haagone kusarudzwa.Longitudinal yakanyura arc welding (UOE simbi pombi) inoshandisa iyo post-weld inotonhora yekuwedzera nzira yekuwedzera pombi, saka geometric saizi yeUOE simbi pombi yakanyatsoenderana, uye kunaka kwemuenzani kana UOE simbi pombi yakabatana yakanaka. kuve nechokwadi chemhando yewelding.Chikamu chekushushikana kwemukati chinobviswa.Mukuwedzera, multi-waya welding (matatu-waya, mana-waya) inoshandiswa kuUOE simbi pombi welding.Iyi welding process inogadzira mashoma mutsara simba panguva yewelding uye ine simba shoma pane inopisa-inokanganiswa nzvimbo ye base simbi.Iyo post-pass welding wire ye-multi-waya welding inogona kuita basa mukubvisa kushushikana kunogadzirwa panguva yewelding kune yakapfuura welding waya, nekudaro ichivandudza michina yepombi yesimbi.
Kuenzaniswa ne spiral welded pombi, kureba kwe weld seam yeyakatwasuka musono yakanyura arc welded simbi pombi ipfupi, saka welding urema uye pesvedzero idiki.Mupombi yepipeline yepamusoro-soro, simbi yepasi yepombi yakatwasuka inogona kuwana 100% ultrasonic flaw yekuona mahwendefa esimbi rimwe nerimwe, richisangana nezvinodiwa zvepipeline yepamusoro-soro yesimbi yepasi.Zvisinei, kunyange zvazvo kushanda kwakazara kweUOE simbi pombi kuri nani pane mamwe mapaipi esimbi, mutengo wayo wepamusoro unoita kuti vashandisi vasina mari vaore mwoyo.Iyo welds ye spiral simbi pombi inogoverwa mune inotenderera chimiro.Kazhinji, iyo weld nzvimbo yepombi yesimbi, kusanganisira iyo inopisa-inokanganisa nzvimbo ye weld, ndiyo chikamu chine urombo hwemagetsi epombi yesimbi, nepo kushushikana kwakanyanya kwemukati kwepombi yekumanikidza kunogoverwa pamwe neaxial direction, uye iyo spiral welded pombi ichaita Zvikamu zvisina simba zvinodzivirira kutungamira kwekunetseka kwakanyanya kwemukati, nekudaro kuvandudza kushanda kwepombi yesimbi.Pamusoro pezvo, nekuda kweiyo seam yekugadzira iyo spiral simbi pombi uye kureba kweiyo musono seam, zvakanyanya kuoma kuita kunze anti-corrosion, uye gaka rinogona kuumbwa pakati pemasevhisi maviri.Iyo tekinoroji inogona kugadzirisa iyo anti-corrosion yeiyo spiral simbi pombi.
