Kaore i te ngawari te ahua o te flange o te reke, he pai te hiri, he whanui te whakamahi, he rite te rigidity me nga whakaritenga elasticity me te whakawhiti kikokore o te reke reke, he nui te tawhiti o te hononga mai i te mata hono, he nui te mata o te hononga mai i te wera o te wera, ka nui ake te hanganga tinana mare matatini, e tika ana mo te pehanga, te rerekee o te pāmahana o te paipa, te pāmahana teitei ranei, te pehanga teitei me te paipa iti o te pāmahana, Ko te tikanga ka whakamahia mo te PN nui atu i te 2.5MPa putorino me te hononga valve; I whakamahia ano ki te kawe i te paipa reo utu nui, mura, pahū.
Ka mahia te flange paiherea ma te hangai, ma te mahi hangai ranei. I te wa e whakamahia ana te pereti maitai, te rino waahanga ranei, me tutuki nga whakaritenga e whai ake nei:
1.Ko te flange reke fehokotaki'anga kia tirohia e te ultrasonic, kahore koha delamination;
2.Me tapahia ki nga takai i te taha o te hurihuri maitai, ka paiherea ki roto i te mowhiti ma te piko, me te mata o te maitai hei hanga i te rango o te mowhiti. Ko te pereti maitai e kore e miihini tika ki roto i te kopa whiri o te kaki;
3.Ko te weld reke o te whakakai me tango te weld penetration tonu;
4. Ko te weld reke o te mowhiti ka tukuna ki te maimoatanga wera i muri i te welding, ka tukuna ki te 100% hihi, te tirotiro ultrasonic ranei, ka tutuki nga whakaritenga II o JB4730 me te tirotiro i te ultrasonic ka tutuki nga whakaritenga I o JB4730.
Kia kaua e nui ake i te 70° te titahatanga o te kaki o waho o te kopa whakapiri. Ko nga tawhā hangarau o te flange reke fehokotaki'anga e tino whakahaeretia i roto i te hanga me te fehokotaki'anga ki te whakarite kia taea e ia te whai wāhi me te uara tino i roto i te hanga me te whakamahi.
