Taupānga
Ko te nuinga o te whakamahi mo te pehanga teitei me te ratonga pāmahana teitei o te kohua (Superheater ngongo, ngongo whakamahana, te ngongo aratohu hau, te ngongo mamaoa matua mo nga kohua teitei me te teitei teitei). I raro i te mahi o te hau rewharewha teitei me te kohu wai, ka waikura te ngongo me te waikura. E hiahiatia ana kia nui te roa o te paipa rino, he nui te aukati ki te waikura me te waikura, me te pai o te hanganga.
Koeke Matua
Koeke o te waro hanganga maitai teitei: 20g, 20mng, 25mng
Te karaehe o te maitai hanganga koranu: 15mog,20mog,12crmog,15crmog,12cr2mog,12crmovg,12cr3movsitib, etc

Roa:
Ko te roa o nga paipa maitai ko te 4 000 mm ~ 12 000 mm. I muri i te whakawhitiwhiti whakaaro i waenganui i te kaiwhakarato me te kaihoko, me te whakakii i te kirimana, ka taea te tuku paipa rino me te roa nui atu i te 12 000 mm ranei te poto ake i te I 000 mm engari kaua e poto ake i te 3 000 mm; te roa poto Ko te maha o nga paipa maitai iti iho i te 4,000 mm engari kaua e iti iho i te 3,000 mm kaua e neke ake i te 5% o te tapeke o nga paipa rino ka tukuna
Taumaha tuku:
I te wa e tukuna ana te putorino maitai kia rite ki te diameter o waho me te matotoru o te pakitara ingoa, te diameter o roto ranei me te matotoru o te pakitara ingoa, ka tukuna te paipa maitai kia rite ki te taumaha. Ka taea hoki te tuku kia rite ki te taumaha o te ariā.
Ka tukuna te putorino maitai kia rite ki te diameter o waho me te matotoru o te pakitara iti, ka tukuna te putorino maitai kia rite ki te taumaha tonu; ka whiriwhiri nga roopu tuku me te tono. A ka tohuhia i roto i te kirimana. Ka taea hoki te tuku i te putorino maitai kia rite ki te taumaha o te whakaaro.
Taumaha:
E ai ki nga whakaritenga a te kaihoko, i muri i te korerorero i waenga i te kaiwhakarato me te kaihoko, me te kirimana, ko te rereke i waenga i te taumaha me te taumaha o te putorino maitai tuku ka tutuki nga whakaritenga e whai ake nei:
a) Pupa maitai kotahi: ± 10%;
b) Ia puranga paipa maitai me te iti rawa o te 10 t: ± 7.5%.
Whakaritenga Whakamatau
Whakamātautau Hydraustatic:
Ko te putorino maitai me whakamatauhia ma te hydraulicly tetahi. Ko 20 MPa te pēhanga whakamātautau mōrahi. I raro i te pehanga whakamatautau, ko te wa whakapumau kia kaua e iti iho i te 10 s, kaua hoki te putorino maitai e pakaru.
I muri i te whakaae a te kaiwhakamahi, ka taea te whakakapi i te whakamatautau waipēhi e te whakamātautau eddy nāianei, te whakamātautau rerenga rerenga autō ranei.
Whakamātautau kore kino:
Ko nga paipa e hiahia ana kia nui ake te tirotiro me tirotirohia e tetahi i tetahi. I muri i te whiriwhiringa me kii te whakaaetanga o te roopu me te tohu i roto i te kirimana, ka taea te taapiri atu i etahi atu whakamatautau kore-kino.
Whakamātautau Whakapapa:
Ko nga ngongo he nui ake i te 22 mm te diameter o waho ka tukuna ki te whakamatautau papatahi. Karekau e kitea he delamination, he wahi ma, he poke ranei i te wa o te whakamatautau.
Whakamātautau mura:
E ai ki nga whakaritenga a te kaihoko me te kii i roto i te kirimana, ka taea te mahi i te putorino maitai me te diameter o waho ≤76mm me te matotoru o te taiepa ≤8mm ka taea te whakamatautau mura. I mahia te whakamatautau i te pāmahana rūma me te taper o 60 °. I muri i te pupuhi, ko te reiti mura o te diameter o waho me tutuki nga whakaritenga o te tepu e whai ake nei, me nga mea whakamatautau kaua e whakaatu i nga pakaru, i nga pakaru ranei.
