Kunzwisisa Kaviri Welded Pipe uye Spiral Welded Steel Pipe ASTM A252
Nhanganyaya:
Munzanga yanhasi, kufambiswa kwakanaka kwezvinwiwa nemagasi kwakakosha kumaindasitiri mazhinji.Chimwe chezvinhu zvakakosha mukuona kushanda zvakanaka kweiyo yakopombi line systemari kusarudza pombi dzakakodzera.Pakati peakasiyana sarudzo dziripo, S235 JR Spiral Steel Pipe isarudzo yakavimbika nekuda kwemhando yayo yepamusoro.Iyi blog ine chinangwa chekuongorora mabhenefiti ekushandisa S235 JR spiral simbi pombi mumapombi masisitimu, inotarisa pane yayo spiral welded chimiro.

1. Nzwisisa S235 JR spiral simbi pombi:
S235 JR spiral simbi pombiis a spiral welded pombi inoshandiswa zvakanyanya mumapaipi masisitimu.Iwo akagadzirwa nesimbi yepamusoro-soro mukuteerana nezviyero zvepasi rose, kuve nechokwadi chepamusoro kusimba uye kusimba.Nzira yekugadzira inosanganisira kuumbwa kwe spiral yesimbi inoenderera mberi, iyo inobva yasungirirwa kusvika pahurefu hunodiwa.Iyi nzira yekuvaka inopa mapombi ane zvakakosha zvakakosha pane echinyakare akatwasuka-seam pombi.
2. Zvakanakira spiral welded pombi kuvaka:
Iyo spiral welded kuvakwa kweS235 JR Spiral Steel Pipe inopa akawanda mabhenefiti kumapombi masisitimu.Kutanga, iyo inopfuurira spiral weld seams inosimudzira chimiro chekuvimbika kwepombi, ichiita kuti ive yakanyanya kupikisa mukati nekunze kumanikidzwa.Ichi chimiro chinovimbisawo kunyange mutoro wekugovera, kuderedza njodzi yekutadza kwepombi.Uye zvakare, iyo spiral chimiro chepombi inobvisa kudiwa kwekusimbisa kwemukati, nekudaro optimize kuyerera kugona uye kudzikisa kurasikirwa kwekumanikidza panguva yekufambisa kwemvura.Iyo isina musono inoenderera mberi yepiping pombi inoderedza njodzi yekudonha uye inovandudza kuchengetedzeka uye kugona kwepombi system.
3. Wedzera kusimba uye kuita zvakasiyana-siyana:
S235 JR Spiral Steel Pipe inopa kusimba kwepamusoro nekuda kwemhando yepamusoro yekuvaka.Ivo vanoshingirira mukuora, abrasion uye yakanyanyisa mamiriro ekunze, zvichiita kuti ive yakanaka kune akasiyana maapplication anosanganisira kutakura oiri uye gasi, masisitimu emvura nemapurojekiti ezvivakwa.Izvo zvakasiyana-siyana zvepombi idzi dzinovabvumira kuti vagadziriswe nyore nyore kuti vasangane nezvinodiwa zvepurojekiti.Pamusoro pezvo, ivo vari nyore kuisa nekuchengetedza, vachiwedzera kuwedzera kune yavo kukwezva uye kubatsira kuguma mune inodhura-inoshanda uye nguva-inoshanda ductwork system.
4. Kubatsira kwezvakatipoteredza uye kuenderera mberi:
Kuchinjira kuS235 JR spiral simbi pombi mumapombi masisitimu kunogonawo kuunza zvakakosha zvakatipoteredza.Hupenyu hwavo hurefu uye kuramba kudzikisirwa kunoderedza kudiwa kwekugara uchitsiviwa, zvichikonzera kuderera kwekabhoni uye kushomeka kwemarara.Pamusoro pezvo, kudzokororwa kwesimbi kunoita kuti mapombi aya ave sarudzo yakagadzikana inoenderana neyakatenderera hupfumi hwemisimboti.Nekushandisa S235 JR spiral simbi mapaipi, maindasitiri anogona kuve nechokwadi chekuwedzera hushamwari uye ane mutoro nzira yekutakura mvura, nekudaro vachisimudzira remangwana rakasvibira.
Mhedziso:
Iko kushandiswa kweS235 JR spiral simbi pombi mumapombi masisitimu kunopa huwandu hwezvakanakira zvakakosha, zvinosanganisira kusimbiswa kwakasimba, kuchengetedza uye kushanda nesimba.Iyo spiral welded chimiro inovimbisa kutendeseka kwayo uye inopa yakavimbika kuburitsa kwemvura kune akasiyana maindasitiri.Nekubatanidza matekinoroji epamberi seaya, tiri kugadzira nzira yemamwe mapombi akasimba uye akavimbika.
