▇ ▍ Tsanangudzo
Welded simbi pombi inogadzirwa uchishandisa furati simbi mahwendefa kana simbi mitsetse, uye maitiro ayo ekugadzira anogadzira seams mumuviri wayo.Kunyanya, kana pombi dzesimbi dzakasungwa dzichigadzirwa, ndiro kana tambo yesimbi inogochwa yobva yasungwa kuita denderedzwa, chimiro chepombi yechinyakare kana kuti sikweya. Pombi yeLSAW, pombi yeSSAW neERW pombi dzose dzakaiswa simbi mapaipi uye anoiswa muboka zvichibva pa nzira ye welding.Semuenzaniso, pombi yeLSAW inosungirirwa kureba, uye pombi yeSSAW ine spiral-welded.ERW pombi ielectric resistance yakasungwa, izvo zvinoita kuti pave nemusono unomhanya wakafanana uchitevedza muviri wepombi.
▇ ▍ERW Simbi Pipe
Mapaipi akakwenenzverwa epamusoro-soro anowanzo kutsemuka, asi mapaipi esimbi akatwasuka haafanire kuve akaiswa welded.Iyo yakakwira-frequency yakatwasuka-yakatsemuka yemagetsi kuramba welded simbi pombi inoumbwa neganda mhedzisiro uye kuswedera kwemhedzisiro yeyakakwira-frequency ikozvino mushure meiyo inopisa-yakakungurutswa coil ndiro inogadzirwa nemuchina wekuumba, uye kumucheto kwechubhu isina chinhu. yakapisa uye yakanyungudutswa, uye kudzvanywa welding kunoitwa pasi pechiito chekutsikirira roller kuti uone kugadzirwa.Iyo yakakwirira-frequency kuramba yakashongedzerwa simbi pombi yakasiyana neyakajairika welded pombi welding process.Iyo weld inogadzirwa neyakagadzika zvinhu zvesimbi strip body, uye iyo mechanic simba iri nani pane iyo ye general welded pombi.Iyo yepamusoro inotsvedzerera, yakakwirira chaiyo, yakaderera mutengo, uye ine yakaderera weld musono kureba, iyo inobatsira pakupfekedzwa kwe3PE anti-corrosion coating.
▇ ▍LSAW Simbi Pipe
Longitudinal yakanyura arc welded inogadzirwa nekushandisa imwe yepakati uye gobvu ndiro seyakagadzirwa, kudzvanya (kutenderedza) ndiro yesimbi muforoma kana kugadzira muchina muchubhu isina chinhu, uchishandisa kaviri-mativi akanyura arc welding, uye kuwedzera dhayamita.Iyo simbi ndiro yekudyisa huwandu inogona kugadziridzwa otomatiki zvichienderana neakasiyana simbi mamakisi, ukobvu hwemadziro, uye upamhi hwendiro.Panguva imwecheteyo, iyo deformation compensation basa inobudirira inodzivirira iyo yakaipa mhedzisiro ye mold deformation pakugadzira uye inovimbisa kupfava kwehurefu hwakazara hwesimbi ndiro panguva yekutsikirira.Nhanho yekudyisa iyunifomu panguva yekugadzira, kuve nechokwadi kutenderera kwechubhu isina chinhu uye kupfava kwemupendero wewelding.Chigadzirwa chakapedzwa chine huwandu hwakasiyana hwekutsanangurwa, uye weld ine kusimba kwakanaka, plastiki, kufanana, uye compactness.Iine zvakanakira pombi dhayamita hombe, pombi madziro ukobvu, high-pressure resistance, yakaderera-temperature resistance, uye yakasimba corrosion resistance.
▇ ▍SSAW Simbi Pipe
Spiral welded pombi (SSAW pombi, inonziwo HSAW pombi).Iyo pombi inoumbwa ne spiral undermerged arc welding tekinoroji.Spiral welded pombi inoumbwa uchishandisa yakamanikana mahwendefa kana inopisa yakakungurutswa coils, iyo inoderedza mutengo wavo wekugadzira zvakanyanya.Mutsara we welding yakaita sehelix.Iyo spiral welding process inobvumira kugadzirwa kwepombi dzakakura-dhayamita dzakakodzera kutakura mavhoriyamu makuru emafuta negesi.Mamwe mapaipi eSSAW aive ekare akaganhurirwa kune yakaderera-kudzvanywa zvikumbiro.
