Spiral Yakanyura Arc Welding MuOiri Pipe Line Kuvaka: Kuve nechokwadi cheSevhisi Hupenyu uye Kuvimbika
Dzidza nezveHSAW:
Spiral yakanyura arc weldingtekinoroji yepamberi yewelding inosanganisa misimboti yakanyura arc welding uye spiral chubhu kugadzira.Zvinosanganisira kushandisa otomatiki welding process kugadzira inoenderera spiral weld nekudyisa waya yakasimba yekuzadza mune inoyerera-yakafukidzwa arc.Iyi nzira inogonesa kuenderana uye kwemhando yepamusoro welds, kubvisa njodzi yekuremara kwakajairika nedzimwe nzira dzewelding.

Kukosha kweHSAW mukuvaka pombi yemafuta:
1. Simba uye Kugara kwenguva refu: Chimwe chezvinhu zvakakosha zveHSAW kugona kwayo kuumba majoini akasimba, ane simba repamusoro-soro.Iyo inoenderera inotenderera weld inoumbwa neiyi tekinoroji inosimudzira kuvimbika kwechimiro uye yakakosha kumirisana nekumanikidza kwakanyanya, tembiricha yakanyanyisa uye zvakatipoteredza zvinhu izvo.pombi yemafuta mitsetsechiso munguva yehupenyu hwavo hwebasa.
2. Hupenyu hurefu uye kuvimbika kwakasimba: Mitsetse yepombi yemafuta inotarisirwa kushanda zvisina mhosva kwemakumi emakore, kutakura mafuta pasina kubuda kana kutadza.HSAW inoita basa rakakosha mukuwana hupenyu hurefu hwesevhisi nekuona kunyangwe kugoverwa kwekupisa kwewelding, kuderedza kushushikana, nekudzivirira kutangwa kwekutsemuka nekupararira - zvese zvinokonzeresa kuvimbika kwepombi.
3. Kuvaka kunoshanda: HSAW inokwanisa kuramba ichiturika zvikamu zvakareba zvepombi, saka ine basa rakakura mukuvaka pombi.Iyi nzira inoderedza nguva yewelding, inowedzera kubereka, inoderedza zvakanyanya mari yekuvaka, uye inobatsira pakupedzwa nenguva kweprojekti.
4. Kuderedzwa kwekugadzirisa nekugadzirisa: Nekupa hupamhi hwepamusoro, husina kukanganisa-isina welds, HSAW inoderedza kudiwa kwekugadzirisa kweramangwana kana nguva yekugadzirisa-yakabatana.Mapombi emafuta anovakwa achishandisa nzira iyi haanyanyi kudonha kana kutadza, kuvandudza kuchengetedzwa uye kuwedzera kushanda zvakanaka.
5. Mabhenefiti ezvakatipoteredza: HSAW inova nechokwadi chekugadzirwa kweiyo chaiyo welds nehupamhi hwepamusoro-soro.Izvi zvinoderedza mukana wekuora kwepombi uye kudonha kweoiri kunotevera, kuchengetedza nharaunda kubva kunjodzi dzinogona kuitika dzine chekuita nekutadza kwepombi.
