Momo Taper Annular BOP
Āhuahira
1) Whakamahia te wae tarapi me te upoko o te BOP me te tinana e honoa ana e nga poraka raka.
2) Ko te hiri hihiri BOP e tango ana i te mowhiti hiri ki te ngutu hei whakaiti i te kakahu o te mowhiti hiri me te whakarite i te hiri pono.
3) Ko te piston anake me te waeine takai kei te neke i nga waahanga, he pai te whakaiti i te waahi kakahu me te whakapoto i te waa tiaki me te whakatika.
4) Ko nga mea konganuku katoa ka pa atu ki nga wai puna me tutuki nga whakaritenga a NACE MR 0175 mo te mahi kawa.
5) Ma te pehanga pai te hiri.
Whakaahuatanga
Kei roto i tenei hua he hiri ngutu me te kaha hiri-whaiaro kia pai ake te pono. He poka kei roto i te piston mo te whakamatautau whiu hei ine i te oranga o te rapa. Ko te hononga paraharaha maikuku whakarite hononga pono, ara te ahotea anga me te whakaurunga watea. Ko ona piston o runga he koeko te ahua, ka puta he iti te diameter o waho o te hua. I tua atu, ko te mata o te waku he pereti tohu abrasion hei tiaki i te pane me te ngawari ki te whakakapi.
