    Kuphatikiza pa S235 J0 chitoliro chachitsulo chozungulira, mzere wathu wazinthu umaphatikizaponsoA252 Gulu 3 chitoliro chachitsulo.Chogulitsacho chimapangidwa pogwiritsa ntchito matekinoloje aposachedwa kwambiri omwe amatsimikizira miyezo yapamwamba kwambiri komanso yodalirika.Ndi mphamvu zake zolimba kwambiri komanso kukana kwa dzimbiri, chitoliro chachitsulo cha A252 Grade 3 ndichoyenera kugwiritsa ntchito movutikira.

    Ndife onyadira kupereka mzere wathunthu wa spiral submerged arc welded chitoliro chomwe chimakwaniritsa ndikupitilira miyezo yamakampani.Kudzipereka kwathu ku khalidwe ndi luso lapanga ife kukhala ogulitsa odalirika ku mafakitale azitsulo zachitsulo.Ndi kudzipereka kuchita bwino, tikupitiriza kukankhira malire a zitsulo chitoliro kupanga.

    Pankhani ya spiral submerged arc welded chitoliro, zogulitsa zathu zimayika muyeso wa magwiridwe antchito, kulimba komanso kudalirika.S235 J0 Spiral Steel Pipe ndi A252 Grade 3 Steel Pipe ndi zitsanzo ziwiri zokha za kudzipereka kwathu kupatsa makasitomala athu mayankho abwino kwambiri.Timayang'ana kwambiri zaukadaulo komanso zatsopano ndipo tadzipereka kukwaniritsa zosowa zamakasitomala athu ndikupitilira zomwe akuyembekezera.

    Mwachidule, chitoliro chathu chachitsulo cha S235 J0 chozungulira ndi chitoliro chachitsulo cha A252 grade 3 ndi zotsatira zaukadaulo wamakono komanso luso lapamwamba.Zogulitsazi zimapereka ntchito zosayerekezeka, zomwe zimawapanga kukhala osankhidwa bwino pazantchito zosiyanasiyana.Kaya ndi zomangamanga, zomangamanga kapena ntchito zamafakitale, mapaipi athu ozungulira ozungulira arc amapangidwa kuti apereke zotsatira zabwino kwambiri.Khulupirirani kuti ukatswiri wathu ndi zomwe takumana nazo zidzakupatsani mapaipi apamwamba kwambiri azitsulo pamsika.
