Factory Cheap China High Quality Yakatwasuka Carbon Steel Welded Pipes
Overview
"Dzora chiyero nemashoko, ratidza simba nemhando". Bhizinesi redu rakaedza kumisikidza vashandi vevashandi vane hunyanzvi uye vakagadzikana uye vakaongorora maitiro akanaka ekudzora emhando yeStraight Carbon Steel Welded Pipes. Hunhu hwakanaka kuvepo kwefekitori, kutarisisa kudiwa kwemutengi ndiko kunobva kupona kwekambani uye kufambira mberi, Isu tinonamatira kutendeseka uye nekutenda kwepamusoro kushanda maitiro, kuvhima kumberi kune kuuya kwako!
Kune welded kabhoni simbi pombi, pane 2 main tekinoroji inoda kucherechedza kuti ERW(electric resistance weld) uye SAW(submerge arc weld). Mapombi akashandisa tekinoroji iyi ese ari maviri anonyanya kushandiswa indasitiri yepetroleum yekutakura oiri uye gasi, asi ese ane zvawo zvakanakira, saka kushandiswa kwakasiyana.
ERW pombi inogadzirwa kubva mundiro yesimbi, panongova nemusono mumwe chete wakasungwa, uye nekuti mutsara wakakandwa weERW pombi unobva papombi yaamai, haidi solder flux, saka mechanical property yakanaka. Uye nekuda kwehunhu hwayo hwekugona kugadzirwa kwepamusoro, mutengo wakaderera, kuchengetedza zvinhu, uye nyore otomatiki, enzanisa neSAW pombi, ERW pombi pombi yesimbi ine advanced chigadzirwa kuita, inotungamira mhando uye ine hupfumi kuita mumunda wemafuta uye gasi kuchengetedza. uye chekufambisa. Kunyanya kutevedzera kukura kwehunyanzvi, mhando kana welded tambo iri kuwedzera uye iri nani, kuburikidza nekushandisa tekinoroji nyowani, chinangwa ndechekubvisa kushushikana, kupfava uye kunatsa chimiro, uye kugadzirisa yakazara ma mechanics eiyo welding kupisa kwakakanganiswa nzvimbo. Iyi mhando ERW pombi kwete chete weld haigone kusiyaniswa, asiwo iyo weld coefficient inosvika 1, iyo inoziva kuenderana kweiyo weld nzvimbo chimiro neiyo base zvinhu.
SAW tekinoroji yazvino density yakakwira zvakanyanya, uye iyo flux layer inodzivirira kukurumidza kurasikirwa nekupisa uye inoisa iyo munzvimbo ye soldering. Yakanyura arc welding ine yakakwira weld seam mhando, yakakwira kugadzirwa, hapana mwenje wearc uye utsi hushoma. Akanyura arc welded simbi mapaipi anoshandiswa zvakanyanya mumidziyo yekumanikidza, pombi fittings, matanda, makoramu, yakaderera-kudzvinyirira zvinwiwa, uye mapurojekiti esimbi. Asi muindasitiri yepetroleum yenyika dzakasimukira, pombi yeSAW haitenderwe kupinda nekuti pachayo muganho, muChina SAW pombi ndiyo ichiri kubvumidzwa muindasitiri yepetroleum ine muganhu.
Hunhu hwakanaka uye mutengo unonzwisisika "ndiwo misimboti yebhizinesi redu. Kana iwe uchifarira zvigadzirwa zvedu nemhinduro kana uine chero mibvunzo, ita shuwa kuti unonzwa wakasununguka kutibata nesu. Tinotarisira kutanga hukama hwekushandira pamwe newe munguva pfupi iri kutevera.
Application
Iyo Inonyanya Kushandiswa kune simba uye kumanikidza zvikamu, uye kune zvakajairika chinangwa chiputi, mvura, gasi uye mhepo pombi.
