Dacromet Flange Bolts

Dacromet Flange Bolts
Ko nga Tiaki Flange Anti-Corrosion me te Whakakikorua Tiaki Konumohe-Konumohe
Ko nga tutaki flange Dacromet e whakakotahi ana i te hoahoa upoko flange toha kawenga me te paninga tawerewere konutea-konumohe a Dacromet. Ka whakakapihia e te flange whakauru tetahi kaihoroi motuhake, ka tukuna e te paninga Dacromet nga haora 500-1,200 o te atete rehu tote kaore he hauwai - he pai mo te miihini, te hanga, me nga tono moana.
Wāhanga 1 — Flange Bolt
Ko te raka flange he hex mahunga mahunga me te riipene rite ki te horoi i te turanga o te upoko. Ka tohatohahia e te flange te kawenga awhi ki runga i te waahi whanui, ka whakaheke i te pehanga mata me te aukati i te kino o nga rawa hono. Ka whakakorehia e tenei te hiahia mo te horoi motuhake, ka ngawari te huihuinga.
Nga waahanga matua
- Te tohatoha utaina: Ka horahia e te flange te kaha awhi, ka whakaiti i te ahotea o te kawe ki runga ki te 50% ka whakaritea ki nga tutaki hex paerewa.
- Whakarereke: Ko te kowhiringa flange serrated e whakarato ana i te parenga wiri i roto me te kore e maukati nga horoi.
- Paerewa: DIN 6921 / ISO 4162 / GB / T 5787; M6–M20; Koeke 8.8 me te 10.9 mo ia ISO 898-1.
- Rauemi: Te rino waro (Grade 8.8) ranei te rino iti-kounga (Grade 10.9), kua tineia me te whakamahana.
Wāhanga 2 - Whakakikorua Dacromet
Ko te Dacromet he paninga wai-kore-hiko o te konutea inaki me nga tawerewere konumohe kua herea e nga pūhui chromium. Ka whakamahia ma nga huringa ruku-mio-whakaora i te 280–300°C, e whakarato ana i te parenga waikura e toru-papa me te kore he hauwai.
Hangaia Tiaki
- Tiaki patunga tapu: Ko nga tawerewere konutea he pai te waikura hei whakamarumaru i te rino, ahakoa ka rakurakuhia te paninga.
- Arai tinana: Ko nga tawerewere inaki ka aukati i te makuku, te hāora, me nga katote pirau.
- Te hāngū matū: Ko nga pūhui Chromium he puhoi te whakakore i te konutea me te whakaora whaiaro i nga pakaru moroiti.
Nga Painga Matua
- Karekau he hauwai ebrittlement: Ko te tukanga hiko-kore - he haumaru mo te Tohu 8.8–10.9 nga pou kaha teitei.
- He pai ake te parenga waikura: 500–1,200 haora te rehu tote (ISO 9227), 5–10x pai ake i te whakakikorua konutea.
- Angiangi me te kakahu: Ko te 4–10 µm ka pupuri i te pai o te miro me te hangahanga flange. Kaore e hiahiatia te paopao ano.
- Te wera me te pai-taiao: Ka mau ki te 250°C; Cr⁶⁺-kore, RoHS/REACH ture.
Whakataurite paninga
| Taonga | Dacromet | Whakakikorua Zinc | Hot-Dip Galv. |
| Mapu Tote (haora) | 500 – 1,200 | 96 – 240 | 300 – 1,000 |
| Te Whakakorenga Hauwai | Karekau | Morearea (Gr. 10.9+) | Karekau |
| Matotoru paninga | 4 – 10 µm | 5 – 25 µm | 45 – 85 µm |
| Te Painga o te Miro | iti | Iti | Hiranga |
| Parenga Wera | 250°C | 200°C | 250°C |
| Te ahua | Hiriwa-hina, matte | Kahurangi-ma | Maama / spangled |
Whakarāpopototanga
Ko nga tutaki flange Dacromet e tuku ana i te huinga tino pai o te mahi miihini me te whakamarumaru waikura. Ko te flange whakauru ka tohatoha i te kawenga me te whakangawari i te huihuinga, ko te paninga tawerewere konutea-konumohe Dacromet e tuku ana i te 500-1,200 haora o te aukati rehu tote me te kore he hauwai. Ka whakamahia nuitia enei here ki roto i nga miihini, hangahanga, hiko hau, me nga tono moana he mea nui te awhi pono me te mauroa mo te wa roa.
