ASTM A139 S235 J0 Spiral Steel Pipes
Imwe yemabhenefiti makuru eS235 J0 spiral simbi pombindiko kuchinjika kwayo mudhayamita uye kukora kwemadziro kutsanangurwa.Izvi zvinobvumira hukuru hwekugadzira kugadzirisa, kunyanya mukugadzirwa kwepamusoro-giredhi, makobvu-akavezwa mapaipi.Pamusoro pezvo, tekinoroji iyi inonyanya kushanda pakugadzira mapaipi akakomberedzwa nemadziro ediki nepakati madhayamita, achipfuura dzimwe nzira dziripo.

Hunhu hwepamusoro hweS235 J0 spiral simbi pombi inoita kuti ive yakakodzera kune akasiyana maapplication.Ingave maindasitiri, ekutengesa kana mapurojekiti ezvivakwa, chigadzirwa ichi chakagadzirirwa kusangana nezvinodiwa nevashandisi vacho.Kuita kwayo kwakavimbika uye kusimba kunoita kuti ive mhinduro inodhura kune chero chirongwa chinoda spiral undermerged arc tubes.
Kuwedzera kune S235 J0 spiral simbi pombi, yedu chigadzirwa mutsara inosanganisirawoA252 Grade 3 simbi pombi.Chigadzirwa chinogadzirwa pachishandiswa azvino kugadzira matekinoroji kuve nechokwadi chemhando yepamusoro uye kuvimbika zviyero.Nekusimba kwayo kwakasimba uye kwakanakisa kusakara kwegora, A252 Giredhi 3 pombi yesimbi yakanakira kukumbira maapplication.
Isu tinodada nekupa mutsara uzere we spiral undermerged arc welded pombi inosangana uye inodarika indasitiri zviyero.Kuzvipira kwedu kumhando uye hunyanzvi kwatiita mutengesi akavimbika kune indasitiri yesimbi pombi.Nekuzvipira kune zvakanakisa, isu tinoenderera mberi nekusundira miganhu yesimbi yekugadzira pombi.
Kana zvasvika kune spiral yakanyura arc welded pombi, zvigadzirwa zvedu zvinoisa mwero wekuita, kusimba uye kuvimbika.S235 J0 Spiral Steel Pipe uye A252 Giredhi 3 Steel Pipe ingori mienzaniso miviri yekuzvipira kwedu kupa vatengi vedu mhinduro dzakanakisa.Isu tinotarisa pamhando uye hunyanzvi uye takazvipira kuzadzisa zvinodiwa nevatengi vedu uye nekupfuura zvavanotarisira.
Muchidimbu, yedu S235 J0 spiral simbi pombi uye A252 giredhi 3 simbi pombi mhedzisiro yekucheka-kumucheto tekinoroji uye hunyanzvi hwepamusoro.Zvigadzirwa izvi zvinopa kuita kusingaenzaniswi, zvichiita kuti ive sarudzo yakakwana yemhando dzakasiyana dzekushandisa.Zvingave zvekuvaka, zvivakwa kana maindasitiri mapurojekiti, yedu inotenderera yakanyura arc welded mapaipi akagadzirirwa kuunza mhedzisiro yepamusoro.Vimba kuti hunyanzvi hwedu uye ruzivo zvinokupa iwe yepamusoro mhando mapaipi esimbi pamusika.
