Mumunda weinjiniya yezvimiro, kukosha kwekushandisa zvinhu zvemhando yepamusoro uye nzira dzekuvaka hazvigone kuwedzeredzwa.Pakati pezvinhu zvakasiyana-siyana zvinoshandiswa muzvirongwa zvekuvaka, mapaipi anoita basa rinokosha.Isu tinozojekesa kukosha kwemapombi akaiswa kaviri uye kuongorora maitiro avo, mabhenefiti uye mabatiro avanogona kubatsira kusimbisa kuvimbika kwechimiro.

Dzidza nezvemapombi akaiswa kaviri:

Kaviri welded pombi, inozivikanwawo sembiri yakanyura arc welded pombi (DSAW Mapaipi), inogadzirwa uchishandisa yakanyura arc welding process.Iyo tekinoroji inosanganisira kureba kusanganisa mahwendefa maviri esimbi akaparadzana, achipa kubatana kwakasimba uye kunoramba kuripo.Mapaipi aya anonyanya kushandiswa mukumanikidza kwakanyanya, mvura yepasi uye gasi pombi, kuongorora mafuta, uye mapuratifomu ekumahombekombe.

Wedzera kurongeka kwechimiro:

Chikonzero chikuru chekushandisakaviri welded pombindiko kugona kwavo kusimudzira kuvimbika kwechimiro.Iine isina musono uye yakasimba welds, mapaipi aya anopa hukuru hwekushushikana kusagadzikana uye kusimba.Iyo kaviri weld inova nechokwadi chekuti pombi inokwanisa kumirisana nepamusoro-soro mazinga, ichiita kuti ive yakakodzera kune yakakosha maapplication uko weld imwe chete inogona kukanganisa kuchengetedzwa kwechimiro.Iyi yehuviri welding process inobvisa mukana wekuvuza kana kutsemuka, kuve nechokwadi chekuvimbika kwenguva refu kwepombi yako system.

Yakakwira simba kune huremu reshiyo:

Kaviri welded pombi inopa yakanakisa simba kune huremu reshiyo.Nekuda kweiyo welding process, mapaipi aya akadzikisa kukora kwemadziro uye akareruka achichengetedza kusimba kwechimiro.Iyi simba-ku-huremu reshiyo inobatsira inoderedza mutoro wakazara pane chinotsigira chimiro, zvichiita kuti ive inodhura-inoshanda mhinduro yemapurojekiti makuru akadai semabhiriji, shongwe, uye zvivakwa zvepamusoro.

Corrosion resistance:

Imwe bhenefiti yakakosha yepombi yakashongedzwa kaviri ndeyekupokana kwayo.Iyo yakasimba welded chisimbiso inogadzira chipingamupinyi chakasimba kurwisa zvinhu zvekunze, zvinosanganisira unyoro, makemikari uye ivhu.Izvi zvinodzivirira mukati mepombi kuti isasangana yakanangana neanoora, kuve nechokwadi chehupenyu hwesevhisi hurefu kana ichienzaniswa nemapombi akajairwa.Izvo zvisingadziviriri zvimiro zvepombi idzi zvakanyanya kubatsira kuindasitiri yemafuta negesi, uko pombi dzinowanzosangana nemamiriro akaomarara.
