Ko te takirere kati e pa ana ki te kupu kuaha e neke ai te wahi kati (te whanui whanui) i te raina waenganui o te nohoanga takirere.E ai ki tenei ahua nekehanga o te kōpae takirere, ko te huringa o te tauranga nohoanga takirere he rite ki te whiu takirere.I te mea he poto te whakatuwheratanga, te kati kati ranei o te kakau takirere o tenei momo takirere,
I tua atu, he tino pono te mahi tapahi, a na te mea ko te huringa o te tauranga tuuru takirere he rite ki te whiu o te kōpae takirere, he tino pai mo te whakatikatika rere.Na reira, he tino pai tenei ahua o te kati kati mo te whakamahi hei kati-atu, whakatikatika ranei me te tarai.
Ko te tino painga o te maataki o te ao ko te wa i te whakatuwhera me te kati, ko te waku i waenga i te papa whanui me te mata hiri whanui he iti ake i tera o te keeti kuaha, na reira ka mau-atete.Ko te teitei o te whakatuwheratanga he 1/4 noa iho o te diameter o te tuuru tuuru takirere, no reira he iti ake i te paera kuaha.
I te nuinga o te waa he kotahi noa te mata hiri i runga i te tinana takirere me te kōpae takirere o te takirere mutu, no reira he pai te mahi hangahanga o te paera mutu, a he ngawari te pupuri i te paera mutu.Te pehanga ingoa, te taumata pehanga ranei o te puera ao: PN1.0-16.0MPa, ANSI CLASS150-900, JIS
10-20K, te diameter o te ingoa, te tima ranei: DN10 ~ 500, NPS1 / 2-36, mutu te tikanga hononga valve: flange, reke fehokotaki'anga, miro, me ētahi atu, pāmahana hāngai: -1969℃-700℃,
Te aratau taraiwa: te a-ringa, te taraiwa taputapu bevel, te pneumatic, te hiko, te waipēhi, te hononga hau-wai, te hononga hiko-waiwai,
Nga rauemi tinana whanui: WCB, ZG1Cr18Ni9Ti, ZG1Cr18Ni12Mо2Ti, CF8 (304), CF3 (304L), CF8M (316), CF3M (316L), Ti,
He rereke nga rauemi e whakamahia ana mo te whakatikatika tapahi, ka taea te whakamahi ki nga momo panui penei i te wai, te mamaoa, te hinu, te waikawa nitric, te waikawa acetic, te reo oxidizing, te Urea, etc.
