He Toa Hononga Waihiko Waihiko Nga Kaihono NPSM Hononga / Kaiwhakauru
Whakataki Hua
Tohu toa NPSM tūhono ko te tikanga he NPSM miro wahine hono mutunga i roto i te tūhono, NPSM he American National Pipe Straight Mechanical miro, mohiotia hoki ko ANSI / ASME B1.20.1 miro paipa.
Ko te miro NPSM he miro paipa tika, ko te NPT he miro taper.Ko te hurihanga wahine NPSM e hono ana te pito ki te koeko 60°, ka hiritia ki te whakataetae ki te tane NPT me te noho koeko 60°, tirohia te pikitia i raro nei.
Ko nga rahi o te miro NPSM mo nga hononga Winner ko: 1/8"-27, 1/4"-18, 3/8"-18, 1/2"-14, 3/4"-14, 1"-11.5, 1.1/ 4”-11.5, 1.1/2”-11.5, 2”-11.5.
Me pehea te tautuhi he miro NPSM me te whakatau i te rahi o te miro?
1.Tirohia te miro o roto, karekau he miro, ka inehia ranei he caliper o roto ki te ine i te diameter iti o te miro o roto he rereke te roa o te waahi he rite te diameter.
2. Inehia te diameter o te miro me te caliper ID, i whanganga ki te diameter o roto, me te pupuri kia tika ki te miro mo te panui wahine tika ake.
3. Inehia nga miro mo ia inihi (TPI), te pitch ranei.I te mea ko te ine ine te whanui me te whakamahi i te ine piro hononga, whakamatauhia nga momo miro rereke kia kitea ra ano te pai rawa atu, uru atu ki te maha o nga miro ka taea, ka nui ake nga miro kua uru, ka tika ake te panui.Puritia te urunga/hononga me te ine puri miro ki runga ki te marama, rapua nga aputa i waenga i te ine me te miro, he maamaa ake te kite i runga i te urunga/honohono miro o waho atu i te urunga/honohono miro o roto.
na te mea ka nui ake i te kotahi te rahi ka rite nga rahi miro.Kei raro ko nga raraunga whakatairite i waengaNPSMmiro wahine vs miro wahine BSP, he rite tonu, no reira me tupato kei uru, kei pohehe ranei.

Fhe hononga hono/whakauru waitohu Winner ranei, he ngawari te tautuhi i te miro NPSM, te miro BSP ranei, tirohia te pikitia i raro iho nei, e toru nga tohu riuwau iti o te miro NPSM i runga i te tohu hex nati, me te miro BSP he tohu riu iti kei runga i te tohu hex nati.
Ko te whakakikorua o te Winner o nga hononga he kore utu o Cr6+, a ko te mahi tiaki waikura i tae ki te 360h kaore he waikura whero, he nui atu i te paerewa noa.
