X42 SSAW Pipe Spiral Welded Tube
Suma:
Munyaya dzemapaipi esimbi, nzira dzakasiyana-siyana dzekunamira dzinoshandiswa kuti pave nekubatana kwemhando yepamusoro uye kwakavimbika. Imwe yenzira dzakadaro ndeiyiwelding ye arc inonyudzwa ne spiral(SAW), iyo ine basa guru mukugadzirwa kwepombi dzeX42 SSAW. Semutungamiri weindasitiri, Cangzhou Spiral Steel Pipe Group Co., Ltd., inozivikanwa nerudzi rwayo rweWuzhou, inotevedzera mitemo yepasi rose uye inova nechokwadi chekuti zvigadzirwa zvayo (kusanganisira pombi dzeX42 spiral submerged arc welded) zvinosangana neAPI Spec 5L, ASTM A139, ASTM A252 uye EN 10219. Mublog rino tinotarisa munyika inonakidza yepombi dzeX42 SSAW, tichiratidza zvakanakira kushandisa spiral submerged arc welding mukugadzirwa kwepombi dzespirally welded.
Dzidza nezve Spiral Submerged Arc Welding (SAW):
Kusonwa kwesimbi inonyungudika, inozivikanwawo seSAW, inzira yekusonwa inoshandiswa kugadzira mapaipi akasonwa sesimbi.Pombi yeX42 SSAWNzira iyi inosanganisira kunyungudutsa waya nesimbi yesimbi uchishandisa kupisa kunobva mukupiswa kwesimbi pakati pewaya nemhepo iri pasi pemvura. Mvura inoshanda sechidziviriro, ichidzivirira kusvibiswa kwemhepo kuti kusapindirane nemaitiro ekusonesa. Nzira iyi ine zvakanakira zvakawanda kupfuura dzimwe nzira dzekusonta.

Kuedzwa kweHydrostatic
Mabhenefiti ekubatanidza arc ne spiral submerged:
1. Kupinza zvinhu zvinoenderana uye zvemhando yepamusoro: Nzira yeSAW inoshandiswa mupaipi yeX42 SSAW inogadzira kupinza zvinhu zvakafanana uye zvemhando yepamusoro. Kana arc ikanyura muflux, inogadzira nzvimbo inodzorwa inodzivirira nzvimbo inonamira kubva kune zvinhu zvekunze, zvichiita kuti pave nekusangana kwakasimba uye kwakavimbika. Izvi zvinoguma nekugadzirwa kwemapaipi ane spiral welded ane simba rakasiyana uye kugara kwenguva refu.
2. Kuwedzera kushanda zvakanaka: Kubatanidza arc inonyudzwa nesimbi inotenderera kunoita kuti zvinhu zvishande zvakanaka nekuda kwehunhu hwayo hwe otomatiki. Maitiro aya anosanganisira kupinza waya yekusanganisa zvinhu otomatiki nguva dzose, zvichiita kuti ibudirire nekukurumidza ukuwo ichichengetedza kunyatsoshanda. Kuwanda kwekuisa zvinhu uye kusavimba zvakanyanya nebasa remaoko kunobatsira pakushanda zvakanaka uye kushandisa mari shoma.
3. Yakakodzera kushandiswa kwakasiyana-siyana: Pombi yeX42 SSAW inogadzirwa ne spiral submerged arc welding inoshandiswa zvakanyanya mumaindasitiri mazhinji. Mapombi aya anoshandiswa mukufambisa mafuta negesi, mapaipi emvura, kutsigira chivakwa, kuisa hwaro hwepombi, nezvimwewo. Kugona kushanda nesimba uye kuvimbika kwechubhu yeX42 SSAW kunoita kuti ive yakakodzera kushandiswa kwakakosha.
4. Hunhu hwemakanika hwakavandudzwa: Nzira yeSAW inoita kuti pave nekudzora kuri nani kwezviyero zvekuwelda panguva yekugadzira mapaipi eX42 spiral submerged arc welded. Kudzora uku kunogona kuwedzera hunhu hwemakanika, kusanganisira kusimba kweimpact, simba remugoho uye simba rekudhonza. Nekuda kweizvozvo, mapaipi aya ane simba rekudzivirira simba rekunze uye akakodzera kunyangwe munzvimbo dzakaoma.
Mukupedzisa:
Patinoongorora nyika ye spiral submerged arc welding mukugadzirwa kwemapaipi eX42 SSAW, zvinova pachena kuti sei nzira iyi ichishandiswa zvakanyanya muindasitiri yesimbi. Spiral submerged arc welding ine mabhenefiti akawanda akadai sema weld seams anochinjika, kuwedzera kushanda zvakanaka, kushanduka-shanduka uye kuvandudzwa kwehunhu hwemakanika, zvichiita kuti mapaipi akasungirirwa ne spirally, akadai semapaipi esimbi eX42 SSAW akagadzirwa neCangzhou Spiral Steel Pipe Group Co., Ltd., asvike padanho repamusoro-soro. Saka, maererano nekuvimbika, kugara kwenguva refu uye kushanda zvakanaka, chubhu yeX42 SSAW inoratidza kuva sarudzo yakanaka kune akasiyana mashandisirwo emaindasitiri.
