A252 Comprehensive Guide KuGiredhi 2 Simbi Pipe: Yakanakira Kaviri Submerged Arc Welded Sewer Line Projects.
Dzidza nezve A252 Giredhi 2 Simbi Pipe:
A252 GRADE 2 Steel Pipeiyo kabhoni simbi pombi yakanyatsogadzirirwa kushandiswa mukumanikidza pombi uye zvimiro zvekushandisa.Iyo inogadzirwa zvinoenderana neASTM (American Society for Testing and Materials) zviyero, kuve nechokwadi chemhando yepamusoro zviyero uye kurongeka kwedimensional.Iyo GRADE 2 zita rinoratidza kuti pombi yesimbi inogadzirwa uchishandisa yakanyura arc welding kana nzira dzisina musono.
Kukosha kwekaviri yakanyudzwa arc welding:
Kaviri yakanyura arc welding, inozivikanwawo seDSAW, inyanzvi yekugadzira simbi inoshandiswa kubatanidza zvikamu zveA252 GRADE 2 pombi yesimbi.DSAW inopa mabhenefiti akati wandei pamusoro pedzimwe nzira dzewelding, dzinosanganisira yakanakisa weld kutendeseka, yakakwira welding kumhanya, kushoma kukanganisa, uye kwakanakisa kutonga kwekupisa kwekuisa.Inochengetedza chisungo chakasimba pakati pepombi, zvichiita kuti isanyanya kudonha, kuparara uye kukanganisa kwemaitiro.

Sei uchishandisa A252 Giredhi 2 pombi yesimbi kumapurojekiti esuweji?
1. KUNYANYA KUSIMBA UYE KUGARA: A252 GRADE 2 pombi yesimbi ine simba rakanyanya kusimba, zvichiita kuti rive rinopesana nekunze kwekunetseka uye kudzvinyirira.Kugara kwavo kunovimbisa hupenyu hurefu hwesevhisi, kuderedza kudiwa kwekugara kuchitsiviwa kana kugadzirisa.
2. Corrosion Resistance: A252 GRADE 2 pombi yesimbi yakagadzirirwa kutsungirira mamiriro ezvinhu akaoma epasi pevhu, kusanganisira kutarisana netsvina, makemikari uye unyoro, pasina kuora kana kukanganisa.Ichi chimiro chinowedzera zvakanyanya hupenyu hwebasa remapombi esuweji.
3. Mari inodhura: A252 Grade 2 pombi yesimbi inopa mhinduro inodhura yekugadzira pombi yetsvina.Zvavanoda zvakaderera zvekuchengetedza uye hupenyu hurefu hunogona kuchengetedza masevhisi uye makondirakiti epurojekiti yakakosha kuchengetedza nekufamba kwenguva.
Kushandiswa kweA252 giredhi 2 pombi yesimbi muinjiniya yetsvina:
A252 GRADE 2 pombi yesimbi inoshandiswa zvakanyanya mumhando dzakasiyana dzemapurojekiti esuweji, kusanganisira:
1. Municipal sewage system: A252 Grade 2 mapaipi esimbi anoshandiswa zvakanyanya pakuvaka mapaipi emasuweji emasuweji ekutakurisa mvura yetsvina kubva kunzvimbo dzinogara uye dzekutengesa kuenda kunzvimbo dzekurapa.
2. Industrial Sewerage System: Zvigadzirwa zvemaindasitiri zvinoda hurongwa hwakasimba hwematsvina ekubata kuyerera kwemvura yakasviba kubva kumagetsi ekugadzira uye zvimwe zvivako.A252 GRADE 2 simbi pombi inopa simba rinodiwa uye kusimba kwerudzi urwu rwemaindasitiri etsvina pombi pombi application.
Mukupedzisa:
Kana zvasvikamutsetse wetsvinakuvaka, A252 GRADE 2 pombi yesimbi yakasanganiswa neDSAW welding tekinoroji inopa simba risingaenzaniswi, kusimba uye kuita kwese.Iyo yakasarudzika corrosion kuramba, simba repamusoro-soro uye mutengo-kushanda kunoita kuti ive yakakodzera kune akasiyana mapurojekiti esuweji.Nekutora izvi zvemberi zvekushandisa uye nzira dzewelding, maguta anogona kuwedzera zvakanyanya hupenyu uye kushanda kweseweji masisitimu, kuderedza mutengo wekugadzirisa uye kuve nechokwadi chekuchenesa, nharaunda ine hutano kumunhu wese.
