Reke Welded Mono Raorere Manga-kore
American Paerewa WeldingMono ValveWhakaahuatanga Poto:
He ngawari te hanganga o te puera mono, he tere tere, he iti te aukati wai, me te mahi whiu koki tere.I te ohorere pera i te aitua, ka tere te hono, te momotu ranei te paipa.Ka whakatauritea ki nga maru o te kuaha me nga reera o te ao, he ngawari ake te mahi me te tere o te whakawhiti.Ka whakamahia e te takirere 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 hiko o te hiri ki te mata hiri huri noa i 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 rauemi me te rahi o te flange o nga waahanga ka taea te rite ki nga tikanga mahi me nga whakaritenga a nga kaiwhakamahi ki te whakatutuki i nga momo hiahia miihini.

Amerika paerewa paiherea nga tohutohu mo te whakaurunga o te mono:
1. Waiho te waahi ka huri te kakau takirere.
2. Kaore e taea te whakamahi mo te tarai.
3. Ko te paera poroporo me te tikanga tuku me whakanoho tika.
