1.Kungotsegula wosanjikiza wakunja, osadzaza mkati mwanu; Nthawi zambiri amagwiritsa ntchito zipilala zapakati komanso zochepa, kupanikizika kwa nomwenal kwa mapaipi ndi ochepera 0.2MPA. Pali mitundu itatu yokokaFlat, omwe ali osalala, mtundu wa conc ndi convex ndi mtundu wa teniove. Pakati pawo, mtundu wosalala ndi wogwiritsidwa ntchito kwambiri, ndipo mtengo wake ndiwotsika mtengo komanso wokwera mtengo.
2.onse amkati ndi kunja kwanyamulaIyenera kuwunikidwa, yomwe imagwiritsidwa ntchito popanikizika pakatikati komanso yokwera kwambiri, ndipo kupanikizika kwa nomwenal kwa pipeline ali pakati pa 0,25 ~ 2.5mpu. Malo osindikizira aKuwalaKulumikiza kumakhala ndi Convebove ndi Convex, ndipo kukhazikitsa kumakhala kovuta, chifukwa chake mtengo wa ntchito, njira yokhazikika ndi zothandizira chuma ndizokwera kwambiri.

3..Nthawi zambiri amagwiritsa ntchito kupanikizika kwadzina ndi yocheperako kapena yofanana ndi 10,0MNA, mulifupi wa somunil ndiwocheperako kapena wofanana ndi 40mm mu paipe.
4..: Nthawi zambiri amagwiritsidwa ntchito payipi ndi kukakamizidwa kochepa koma sing'anga, motero mtundu wamtunduwu umakhala wamphamvu kutunkha, ndipo zinthuzo zimakhala chitsulo chosapanga dzimbiri.
Mtundu wamtunduwu umagwiritsidwa ntchito makamaka polumikizana ndi chitoliro chachitsulo, bush huse, chitoliro chachitsulo chachitsulo ndipovalavu, etc., ndipo kulumikizana kwa zida ndi ma flange kumalumikizidwanso ndi Flange.
