S355 JR Spiral Steel pombi yeSewer Line
S355 JR Spiral Steel PipiSimba uye Kuwedzera
S355 JR Spiral Steel PipiYakagadzirwa uchishandisa Advanced Technology uye yakakwirira-mhando simbi kusanganisa simba uye kuwanda mune chimwe chigadzirwa. Iyi pombi yakagadzirirwa kumira zvakanyanyisa kudzvinyirira, kuvaita kuti vakwanise kuve vakaunganidzwa zvakasiyana siyana. Kunyangwe ichishandiswa kutakura mvura, mafuta kana gasi rechisikigo, mapepa aya anopa kuita zvisingaite uye kusimba.
Yakasimba chimiro uye kutendeka kwakarongeka
Chimwe chezvakanyanya kuzivikanwa Iyi pombi inoratidza spiral seams inove nechokwadi chekusimba kwakanyanya apo kuderedza njodzi yekubvarura kana kutadza. Dhizaini iyi inokatyamadza inogonesa iyo pombi kuti ikwanise kudzivisa mitoro inorema uye mamiriro ekunze ane hutsinye, achiita kuti ive yakanakira kuzvishingisa senge mabhiriji, madhiri uye zvakakwirira-zvakakwira zvivakwa.
