(1) Ko nga whakaritenga mo te aukati i te aukati nui o te maha o nga pāpāho me te kaha o te pāmahana me te kaha o te pāmahana-pāmahana-pāmahana te teitei. I te mutunga, kei te huri haere te matū o nga hua paipa, ka pai ake te whakapai ake i te hakihaki me te tukatuka hangarau.
(2) Te rahi o te hua o te putorino (te tika o te matotoru), te whakarite i te tika ki te whakatairanga i te kitenga ipurangi, kei te haere tonu te hangarau whakahaere aunoa.
(3) Ko te whakaritenga o te whakaiti i te utu o nga hua putorino e whanake ana te tukanga whakaputa ki te ahunga o te waa poto me te tata ki te hanga mutunga.
(4) Ko te ahua o nga whakaritenga hua Piki he kounga teitei, he iti, he pai, he iti te kai.
Ko te hanga ngongo kowhatu wera kua hurihia
Production process of automatic tube rolling unit: (cold centering) heating tube blank → heating → hot centering → perforation → tube rolling → tube blank → heating → hot centering → perforation → tube rolling → uniform sizing reheating → reduction → Cooling → Straightening → Pipe cutting → Reheating → Reduction → Cooling → Straightening → Tapahi PIPE → Te maimoatanga wera → Tirohia → Te maimoatanga wera → Tirohia → Te rokiroki
