Ka pehia te Fin e te raina perehi aa ka pehia te pereti mutunga e te raina perehi hiko hei rongoa, i te wa e piko ana, e tapahi ana, e kopikopiko ana i te ngongo konumohe e te Auto Al Tube Bending Machine me te Skew me te whakakopa i te Miihini Whakapapa. Katahi ka kuhuhia te paipa e ka whakawhänuihia e te Tauira Taurua Insert Tube me te Miihini Whakawhänui kia pai ai te paipa me te tara. I muri i tera, ka paiherea te atanga e Cooper Tube me Aluminum Butt Welding Machine me te pereti mutunga ka whakahiatohia e te Miihini Miihini Huihui Taha. I muri i te kitenga e te Mīhini Whakamātautau Leakage Wai, ka whakahekehia te waeine e te mīhini horoi me te Pūrere Whakatangi.
