Tuatahi,ngongo parahi arahii mua i te tukatuka e kore e taea e whai kapiti, distortion, e kore a tawhio deformation, i roto i te wheketere i hanga he tohu koha, i mua i te tukatuka me whakarite te mata o roto o te ma, kahore he wai kahore hinu.Tuarua, ko te tukatuka o te pipeline ka tukatukahia i runga i nga hoahoa hoahoa, na ko te ahua o te tukatuka me te rahi o te paipa parahi me tutuki nga whakaritenga.Ko te huringa diameter i te whati me whakahaere i roto i te 2% o te diameter paerewa o te paipa maitai.I tua atu, karekau he mura, he pupuhi ranei i te pakaru.Me horoi ano te paipa paipa, kia ma nga papa o roto me waho.Na te mea he mahi ngawari te tukatuka paipa maitai, he tino tiketike te mana o te hapa me te tika o te mahi.Mena kei te hiahia te putorino parahi ki te whakapiri, me tiaki te tukanga whakapiri ma te whakakii hauota.
Tukatuka putorino parahi, i mua i te wehe i te wheketere ka etahi taipitopito o te tukatuka, pērā i te parahi putorino blanking me deburring, i etahi wa i roto i te tikanga ki te whakaputa i tetahi ahua o te putorino parahi, ka whakapiko hoki te putorino parahi tenei mahi;Next me te deburring tukanga ka whakamahi kingongo parahi arahitrimming mihini, putorino tapahi maripi, taputapu, pērā i te rangatira whai hua i roto i te tukanga o te mahi ko te turanga pou tuatahi whakaritea, reoccupy cutter ki te nekehia atu, i roto i te tukanga o te tapahi, me te paipa parahi te kai rite, i roto i tenei ara e taea te tapahi flush a e kore e puta deformation, i roto i te tikanga ki te hanga i te ngongo maeneene, i muri i tapahi ki te parahi trimming me burr, Ki te tango i te sundries i runga i te mata o roto, o waho, 0.3 ~ 0.5MPa hau kōpeke maroke kia whakamahia ki te tango i te sundries.
Te hanga pere parahi, te paerewa whakaputa ongongo parahi arahihe tamaiti parahi rite, katahi ka uru ki roto ki te ngongo parahi hei arahi i te tangi o te tetere o nga taputapu motuhake, te awhi taputapu, i runga i te kete mura ka tohuhia he hinu whakamahana rangi, katahi ka whakamauhia te porowhita e toru hauwhā porowhita, te hauwhā o te porowhita ki muri ka pera. i runga, kia tutuki ra ano te mura ki nga whakaritenga.I muri i te hanga o te mura, kia maeneene, kia maeneene hoki te mata whakapiri o te waha o te haona, kia rite te matotoru, kia kaua e kitea he kapiti me nga hapa rereke.
