1. Seamless simbi pombi itambo refu yesimbi isina misono yakaitenderedza uye ine mhango yemuchinjikwa-chikamu. Inoshandiswa zvakanyanya sepombi yesimbi yekutakura mvura. Kana ichienzaniswa nesimbi yakasimba, inoreruka pakurema kana kupeta uye simba rekurovera kwakafanana. Simbi ine hupfumi muchinjika-chikamu inoshandiswa zvakanyanya mukugadzira zvimiro uye zvemakanika zvikamu, senge mota dhiraivha shafts, oiri pombi dzekubooresa, bhasikoro mafuremu, uye simbi scaffolding inoshandiswa mukuvaka.

2. Welded steel pombi ipombi yesimbi inogadzirwa nesimbi yesimbi kana mitsetse yesimbi mushure mekupetwa nekuumbwa. Maitiro ekugadzira e welded simbi pombi ari nyore, ane akawanda marudzi uye zvakatemwa, kushoma kwekudyara kwemidziyo, uye kugadzirwa kwakanyanya, asi simba rayo rose rakaderera pane iro remapombi esimbi asina musono. Nekukurumidza kuvandudzwa kwekuenderera mberi kwekugadzira simbi yemhando yepamusoro uye kufambira mberi kwewelding uye yekuongorora tekinoroji, mhando yewelds inoramba ichivandudzika, mhando uye zvirevo zvepombi dzesimbi dzakashongedzwa dziri kuwedzera zuva nezuva, uye dzakatsiva isina musono. mapaipi esimbi muminda yakawanda uye yakawanda. Welded simbi pombi dzakakamurwa kuita spiral welded simbi pombi uye yakatwasuka musono welded simbi pombi maererano nechimiro weld. .

Iyo nzira yekugadzira yeyakatwasuka seam welded simbi pombi iri nyore, yakaderera mutengo, kukurumidza kusimudzira, uye yakanyanya kugadzirwa. Kusimba kwe spiral welded steel pombi kunowanzo kukwira kupfuura kweiyo yakatwasuka seam welded simbi pombi. Welded simbi mapaipi ane madhayamita akakura anogona kugadzirwa kubva madiki mabheti, uye welded simbi mapaipi ane madhayamita akasiyana anogonawo kugadzirwa kubva mabheti ehupamhi zvakafanana. Nekudaro, zvichienzaniswa neakatwasuka seam simbi mapaipi ehurefu hwakafanana, kureba kweweld kunowedzerwa ne30 ~ 100%, uye kumhanya kwekugadzira kwakaderera. Naizvozvo, dhayamita diki welded simbi pombi anonyanya kushandisa yakatwasuka musono welding, nepo hombe dhayamita welded simbi pombi anonyanya kushandisa spiral welding.
