Nemitsetse gumi nembiri yekugadzira yeiyo spiral zvibayiro, uye mana ekugadzira matanda eAnti-Corrosion uye anowedzera masisitimu ekusimbisa, isu tave mutengesi anotungamira muindasitiri. Tekinoroji yedu yeudiki inokonzeresa kuti tibudise pombi dzepamhepo ine dhaya ye φ219-φ3500mm uye kurira kwemadziro kwe6-25 .4mm.
Isu takazvipira kupa zvigadzirwa zvemhando yepamusoro izvo zvinosangana neyemukati menesheni zviyero. Chikwata chedu chevanyanzvi nyanzvi vanovimbisa kuti pombi imwe neimwe inotanga kufungidzira mamiriro esimba, kusimba uye kuita. Uyezve, isu tinotangisa kugutsikana kwevatengi uye kupa zvakanakisa mushure-yekutengesa sevhisi kune vatengi vedu vanokosheswa.
Nezvedu s355 J0 Spiral Steel pombi, unogona kuvimba nehunhu hwepamusoro uye kuvimbika kuti yedu mhando inomirira. Kunyangwe iwe uri mumakwikwi anorema kana indasitiri yekuvaka, mapepa edu ekupenga anopfuura zvaunotarisira uye anunura migumisiro yakanaka.

Hydrostatic test
Kureba kwepepe kuchaidzwa nemugadziri kune hydrostatic kumanikidza kuchagadzira madziro kushushikana kwekushaiwa makumi matanhatu muzana yeiyo yakasarudzika shuwa simba rekubereka tembiricha. Dzvinyiriro ichatsanangurwa neiyo inotevera equation:
P = 2st / d
Zvinotenderwa kusiyana kwehuremu uye zviyero
Kureba kwega kwega kwepepe kucharemerwa zvakasiyana uye kurema kwayo hakuzopindiri kupfuura gumi muzana pamusoro kana 5.5% pasi pehuremu hwayo uye huremu hwayo uye huremu hwayo pane urefu hwakareba
Iyo yekunze dhisiki haizosiyane kupfuura ± 1% kubva pane yakatarwa zita rekunze kunze kwedhimoni
