Ka tino whai te hua i ngā turePaerewa GB5310, mā te whakamahi i te kounga teitei15CrMoGHe maitai koranu chromium-molybdenum (Cr: 1.0-1.5%, Mo: 0.45-0.60%), ā, he hanganga kore hononga i hangaia mā te tukanga hurihuri wera me te tukanga kukume makariri, he kaha teitei (kaha kume ≥ 440MPa) me te ātete pāmahana (pāmahana e tika ana ≤ 580℃). He tino pai ōna āhuatanga ārai-waikura me te ārai-ngoki, ā, ka taea e ia te tu atu i te waikura o te mamaoa pēhanga teitei me te hau paru mō te wā roa, ā, ko tōna roanga mahi he neke atu i te 30% teitei ake i ērā o ngā paipa maitai noa. Ka mahia te kimi hapa ultrasonic, te kimi au hurihuri me te whakamātautau pēhanga wai puta noa i te tukanga kia kore ai he pakaru me te kore turuturu, ā, ka eke te taumata haumaru ki te taumata ārahi o te umanga.

‌Kapi maha-āhuatanga, taurite tika o ngā hiahia‌
I hangaia mō ngā wāhanga matua pēnei i ngā kohua teihana hiko, ngā whakamahana nui, me ngā whakamahana anō, he pai mō ngā waeine tino nui me ngā waeine iti-whakahirahira me ngā pūnaha whakaora wera para. E whakamahia whānuitia ana hoki i roto i ngā kaupapa paipa pāmahana teitei me te pēhanga teitei i roto i ngā mara o ngā matū hinu, te ahumahi matū waro, me te whakaputanga tahi. E tautoko ana i te whakaritenga ngāwari o ngā diameter o waho o te 25-762mm me ngā matotoru pakitara o te 2.5-120mm hei whakatutuki i ngā whakaritenga tāutanga o ngā āhuatanga mahi uaua, hei āwhina i ngā kiritaki ki te whakaiti i ngā utu tiaki me te whakapai ake i te whakamahinga pūngao.
