In simbi mutopota indasitiri, welded simbi mutopota iri chaizvo mhando simbi pombi. Yakave yakashandiswa zvakanyanya kune akasiyana minda muhupenyu hwezuva nezuva uye kumwe kushanda kushanda. Uyezve, zvinounza kurerukirwa kwakawanda kumabasa edu ekugara nekugadzira.
General welded pombi: general welding inoshandiswa kuendesa low pressure fluid. Iyo inogadzirwa neQ195A, Q215A, Q235A simbi. Kune akawanda manyoro esimbi mapaipi anoshandiswa zvakanyanya mumapaipi system gore rega. Iyo pombi inofanirwa kuve nekudzvanywa, kukotama, kubata kumeso uye kumwe kuyedza, uye mhando yepasi ndechimwe chikumbiro, uye kazhinji kureba kwekutakura ndeye 4 - 10m, kazhinji inodiwa kutakura zvinhu. Izvo zvinotsanangurwa zvepombi yakashongedzwa inoshandisa zita dhayamita (mm kana masendimita), uye dhayamita rezita rakasiyana nedhayamita chaiyo. The welded nyere rusvingo ukobvu kubudikidza murau zvinosanganisira zvakajairika simbi mutopota uye thickening simbi pombi, uye simbi mutopota nechimiro chepombi kupera kunosanganisira pombi neshinda uye nyere pasina shinda.
Galvanized simbi pombi: kuitira kuvandudza ngura kuramba kwesimbi pombi, tinogona kuva akakurudzira kune yakajairika simbi pombi kazhinji. Inopisa yakanyudzwa yakanyungudutswa yesimbi pombi uye pre galvanized simbi pombi ndiwo maviri makuru akakurumbira marudzi epaipi yesimbi mumusika wazvino wepombi yesimbi. Pre-galvanization inozivikanwawo seguyo galvanized, nekuda kwekuti simbi inokungurutswa kuburikidza neyakanyungudutswa zinc. Mushure mekunge bepa ratumirwa nepaguyo kuti rive nemarara rinochekwa kusvika pakukura rodzokororwa. Ukobvu chaihwo hunoiswa pabepa rese, semuenzaniso pre-galvanized Z275 simbi ine 275g per square metre zinc coating. Imwe yezvakanakira iyo pre-galvanized simbi ine pamusoro inopisa dip galvanized simbi ndeyekuti ine chitarisiko chiri nani.
China simbi pombi vagadziri vanogadzira welded simbi pombi nokutora akafuratira substrates sesimbi ndiro kana HR coil, uye kuumba uye welding navo. Kusarudzwa kwepombi kunogona kuva mugumisiro wenzira dzakasiyana. Nyanzvi dzinofunga kana pombi yesimbi yakatwasuka seam kana spiral welded. Vamwe vanogona kupatsanura zvinhu zvacho kuita chinangwa chazvo semuenzaniso mugodhi, kuchera oiri, zvekurima, kana kugadzira. Imwe yedzakajairika nzira dzekuisa mumapoka welded simbi mapaipi ndeyekutarisa maitiro. Mune mamwe mazwi, kurongedza mapaipi esimbi zvinoenderana nemaitiro ekugadzira uye / kana sub-maitiro. Semuyenzaniso, spiral welded steel pombi sezita rinoratidza, mhedzisiro yekutenderera kwedenderedzwa. Mugadziri anotora ndiro, uye mhepo uye welds iyo substrate yeHR coil kana ndiro yesimbi mune inotenderera. Iyi nzira inonzi helical submerged arc welded (HSAW). Chigadzirwa chinoguma chakareba uye chakakora kupfuura dzimwe nzira. Pakazara, nzira iyi inofarirwa nekuti inoratidza kuti iri nyore, inoshanda, inodhura-inoshanda uye nekukurumidza.
