Reke Welded Mono Raorere Kore-whakahinumihia
American Standard WeldingMono ValveWhakaahuatanga Poto:
He ngawari te hanga o te puera mono, he tere tere, he aukati wai iti, me te mahi whiu koki tere.I te ohorere pera i te aituā, ka tere te hono, te momotu ranei te paipa.Ka whakatauritea ki nga maru kuaha me nga reera o te ao, he ngawari ake te mahi, he tere ake te whakawhiti.Ka whakamahia e te puera mono he tinana mono me te kohao hei mema whakatuwhera me te kati, ka huri te tinana mono me te kakau takirere kia mohio ai te mahi whakatuwhera me te kati.
American paerewa paiherea awhe tono vaolo mono:
He pai mo nga pipeline o te pehanga whakaingoa CLASS150～CLASS600LB, te pāmahana mahi -29°C～180°C mo te hinu, matū, rongoa, tongi, ahumahi hiko, aha atu.
Ko nga ahuatanga o te hanganga o te raima mono paiherea a Amerika:
1. Ko te hua he hanganga whaitake, he hiri pono, he pai te mahi me te ahua ataahua.
2, ka tutuki te hiri o te hiri o te hiri o te hiri ki te taha o te ferrule.ahurei 360° whakarewa ngutu tiaki ferrule.
3. Karekau he kohao o te valve ki te whakaemi i te reo.
4, ko te ngutu konganuku te mahi horoi-whaiaro ina huri te tikaokao, e tika ana mo te kirikiri me te ngawari.
5, rere rua-ara, ngawari ki te whakamahi me te whakauru.
6. Ko nga mea me te rahi o nga waahanga ka taea te whakarite kia rite ki nga tikanga mahi, ki nga whakaritenga a nga kaiwhakamahi ki te whakatutuki i nga momo hiahia miihini.
