Tinodada nekuzivisa chigadzirwa chedu chepamusoro-soro,S235 J0 Spiral Steel Pipe, yakagadzirirwa kusangana nezvinodiwa zviri kukura zvemaindasitiri akasiyana-siyana. Sevagadziri vanotungamira mubasa iri, tinoshandisa tekinoroji yepamusoro uye hunyanzvi kugadzira zvemhando yepamusoro.pombi yemutsetse ine kugara kwenguva refu uye mashandiro akanaka.

Mapaipi edu esimbi anotenderera akagadzirwa nesimbi dzinosungirirwa kuburikidza nehurongwa hwekuwelda arc welding inogadzirwa newaya mbiri dzine mativi maviri. Kuburikidza netekinoroji yekuwedzera temperature inoenderera mberi, tinova nechokwadi chekuti chubhu yega yega inogadzirwa neunyanzvi hwepamusoro uye kugadzikana. Maitiro aya ekugadzira anovimbisa kuti zvigadzirwa zvedu zvinosangana nezvinodiwa zvepamusoro-soro, zvichiita kuti zvive zvakanaka kune akasiyana mashandisirwo.

Zvichienzaniswa nemapombi ekare akasungirirwa,S235 J0 pombi yesimbi inotenderera ine zvinhu zvinotevera zvakakosha:

A. Munguva yekuumbwa, ndiro yesimbi inochinja-chinja zvakaenzana uye haina simba rakawanda. Izvi hazvingorerutsi hupenyu hwepombi chete, asiwo zvinoita kuti pombi igare yakatsetseka uye isina mavanga kana zvikanganiso.

b. Maitiro edu epamusoro ekupinza arc pasi pemvura ane mativi maviri anoita kuti pave nekupinza kwakanyatsonaka munzvimbo yakanaka. Izvi zvinoderedza zvakanyanya kuitika kwezvikanganiso zvakaita semipendero isina kumira zvakanaka, kupatsanurwa kwewelding, uye kupinza kusina kukwana. Nekuda kweizvozvo, mapaipi edu ane mhando yepamusoro yekupinza, ari nyore kudzora uye ane chekuita nekushanda kwakanaka.

C. Hunhu hwakanaka ndicho chinhu chatinonyanya kukoshesa. Saka, tinoita ongororo yakakwana yehunhu hwe100% papombi yega yega yesimbi yatinogadzira. Kuongorora uku kwakazara kunovimbisa kuti mapaipi edu anosangana nezvinodiwa zvepamusoro-soro muindasitiri, zvichikupa rugare rwepfungwa panguva yekugadzira nekushandisa.
