Umshini wepayipi ofakwe i-OD ulungele zonke izinhlobo zokusika ipayipi, i-beveling nokulungiswa kokuphela. Idizayini yohlaka oluhlukanisiwe ivumela umshini ukuthi uhlukane phakathi kuhlaka bese ukhweza eduze kwe-OD yepayipi elisemgqeni noma okokufakwayo ukuze uthole ukubamba okuqinile, okuzinzile. Isisetshenziswa senza ukunemba kokusika okusemgqeni noma ukusika/i-bevel ngesikhathi esisodwa, iphoyinti elilodwa, i-counterbore ne-flange ebheke ukusebenza, kanye nokulungiselela ukuphela kwe-weld epayipini elivulekile, elisukela ku-1-86inch 25-2230mm. Isetshenziselwa izinto eziningi kanye nokuqina kodonga ngephakethe lamandla ahlukahlukene.
