Seamless pombi isimbi refu ine hollow cross section uye isina misono yakaitenderedza.Pombi yesimbi ine mhango yemuchinjikwa uye inoshandiswa zvakanyanya sepombi yekutakura zvinwiwa, sepombi yekutakura oiri, gasi rechisikigo, gasi, mvura, uye zvimwe zvinhu zvakasimba.Kana ichienzaniswa nesimbi yakasimba senge simbi yakatenderedzwa, pombi yesimbi inoreruka pakurema kana iine kukotama kwakafanana uye kusimba.Isimbi ine hupfumi hwemuchinjikwa.Inoshandiswa zvakanyanya mukugadzira zvikamu zvezvimiro uye mekiniki zvikamu, senge petroleum drill rods, mota dzekufambisa shafts, uye mabhasikoro.Uye chikafori chesimbi chinoshandiswa pakuvaka.Kushandiswa kwepombi dzesimbi kugadzira annular parts kunogona kuvandudza kushandiswa kwezvinhu, kurerutsa nzira yekugadzira, kuchengetedza zvinhu uye maawa ekugadzirisa, zvakadai sekukunguruka kunotakura zvindori, jack sleeve, nezvimwewo.Simbi pombi zvakare chinhu chakakosha kune dzakasiyana siyana zvombo.Mapaipi, mabhomba epfuti, nezvimwewo zvinofanirwa kugadzirwa nemapombi esimbi.Machubhu esimbi anogona kukamurwa kuita akatenderera machubhu uye akasarudzika-akaumbwa machubhu zvinoenderana neakasiyana emuchinjiko-chikamu nzvimbo maumbirwo.Sezvo nzvimbo yedenderedzwa ndiyo yakakura pasi pemamiriro ekuenzanisa perimeter, mvura yakawanda inogona kutakurwa ne denderedzwa chubhu.Mukuwedzera, apo chikamu chemuchinjikwa chemhete chinowanikwa mukati kana kunze kwekunze kwemhepo, simba rinowedzera kufanana.Nokudaro, pombi zhinji dzesimbi mapaipi akatenderera.
Zvisinei, pombi dzakatenderera dzinewo zvimwe zvinogumira.Semuenzaniso, pasi pemamiriro ekukotamiswa mundege, mapaipi akatenderera haana kusimba semapaipi akaenzana kana rectangular.Mamwe maranga emuchina wekurima, simbi-huni fenicha, nezvimwe zvinowanzo shandiswa mumapaipi akaenzana uye rectangular.Zvinoenderana nekushandiswa kwakasiyana, mapaipi esimbi akasarudzika ane mamwe maumbirwo emuchinjiko anodiwawo.
