Musiyano mukuru une chekuita nezvinhu zviviri izvi zvinokosha mumaindasitiri inzira yekugadzira zvinhu izvi inonyanya kukanganisa hunhu hwazvo hwemakanika.
1.Mapaipi eSimbi Asina Musono (ERW / SMLS)
Mapaipi asina musono haana musono kana majoini ekuwelda. Anowanzogadzirwa nekupisa, kana kuti kudhirowa kunotonhora, uko simbi yakasimba yakatenderera inoboorwa pakati payo pakupisa kwakanyanya.
Rubatsiro Rukuru: Nekuda kwekuti mapaipi asina musono haana musono wakasungirirwa, kusimba kwechimiro chepombi isina musono kwakafanana pakureba kwepombi. Izvi zvinobvisa mukana wekuti "musono upere," nzvimbo inonyanya kukanganiswa mupombi chero ipi zvayo yakasungirirwa.
Saizi Yakajairika: Zviyero zviri muchigadzirwa ichi zvinowanikwa kakawanda zvichienderana neAPI 5L (pombi yemutsetse),ASTM A106uyeASTM A53(yekushandisa tembiricha yakakwira).
2.Mapaipi eSimbi Akasungirirwa (ERW, LSAW, SSAW)
Mapaipi akasungirirwa anogadzirwa nesimbi yakatsetseka kana strip (coil) inoumbwa kuita denderedzwa. Mipendero yacho inosungirirwa pamwe chete nenzira yekushongedza ine simba guru. Mhando dzacho dzinosanganisira Electric Resistance Welding (ERW), Kukwesha Arc Yakanyudzwa Mumvura Yenguva refu ( Longitudinal Submerged Arc Welding)LSAW), Kushongedza Arc Yakanyudzwa Mumvura (Spiral Submerged Arc Welding)SSAW).
Rubatsiro Rukuru: Kugadzirwa kwetekinoroji yepamusoro kwakasimbisa zvikuru kuvimbika kwemusono we weld. Mapaipi akasungirirwa anowanikwawo muhukuru hwakakura kupfuura musono, zvichibvumira dhizaini yakakura uye kushandiswa kwacho kuchichinjika.
Saizi Yakajairika: Zvichienderana neASTM A53, API 5L nedzimwe nzira dzakawanda dzekuvaka zvivakwa munzvimbo dzakasiyana.
