Pipe Line Welding Spiral Seam Steel Pipes
KuCangzhou Spiral Steel Pipe Group Co., Ltd., Yeduspiral seam pombizvigadzirwa zvemhando yepamusoro zvinosangana nemhando yepamusoro yemaindasitiri.Mapombi edu akagadzirirwa zvakasiyana-siyana zvekushandisa uye anozivikanwa nekugara kwawo, simba uye kusagadzikana kwekuora.
Kabhoni ndicho chinhu chakanyanya kukosha musimbi uye hwaro hwekusiyanisa simbi nesimbi.Yedu spiral seam mapaipi anogadzirwa kubva emhando yepamusoro kabhoni simbi inovimbisa yakanyanya kusimba uye kusimba.Nemhando yavo yepamusoro yekabhoni, mapaipi edu anokodzera huwandu hwakawanda hwemaindasitiri ekushandisa.

Pamusoro pekabhoni, yedu spiral seam chubhu ine zvimwe zvakakosha senge nickel uye chromium.Nickel isimbi ine ferromagnetic inowedzera kusimba rose uye kupenya kwepombi.Pamusoro pezvo, inoramba corrosion uye inovimbisa hupenyu hurefu hwesevhisi kumapombi edu.Chromium, kune rumwe rutivi, chinhu chakakosha musimbi isina tsvina uye ine yakanakisa corrosion resistance.Kusanganisirwa kwechromium mumapombi edu ekutenderera kunowedzera kuwedzera hupenyu hwavo uye kuvimbika.
Imwe yemabhenefiti makuru emapombi edu e spiral seam dhizaini yavo isina musono, iyo inowanikwa kuburikidza neyepamusoro welding tekinoroji.Yedu yemazuva ano SAWH (Submerged Arc Spiral Welding) welding tekinoroji inovimbisa yakasimba uye inogara kwenguva refu chisungo pakati pepombi simbi mahwendefa.Iyi tekinoroji yekushongedza haingokwidzi maitiro emagetsi epombi, asi zvakare inovimbisa yakatsetseka yemukati, iyo inobatsira kuyerera kunobudirira kwemvura dzakasiyana-siyana kana magasi.
Yedu spiral seam mapaipi anoshandiswa zvakanyanya mumaindasitiri mazhinji, anosanganisira oiri negesi, kutakura mvura, kuvaka uye kuvandudzwa kwezvivakwa.Inogona kuitwa mumapurojekiti ekumahombekombe uye ekumahombekombe uye mumapombi masisitimu ezvinangwa zvakasiyana.Nekupokana kwayo kwakanakisa kwekuora uye kusimba kwakasimba, mapaipi edu ndiyo yekutanga sarudzo yepombi welding munzvimbo dzakaoma.
