12Cr1MoVG high pressure alloy steel pipe isiqinisekiso sekhwalithi

Ngenxa yezinqubo ezahlukene zokukhiqiza, ihlukaniswe yaba ipayipi lensimbi eligoqiwe elishisayo (elikhishiwe) kanye nepayipi elibandayo elidonswayo (eligoqiwe) elingenamthungo. Ipayipi elibandayo elidonswe (eligoqiwe) lihlukaniswe ipayipi eliyindilinga kanye nepayipi elimise okukhethekile.

a. Ukubuka konke kokugeleza kwenqubo

Ipayipi lensimbi eligoqiwe elishisayo (elikhishiwe) elingenamthungo: ishubhu eliyindilinga elingenalutho → ukushisisa → ukubhobozwa → ukugoqeka kwama-roll amathathu, ukugoqeka okuqhubekayo noma ukukhishwa → ukuhlubula amapayipi → ukusika (noma ukunciphisa) → ukupholisa → ishubhu elingenalutho → ukuqondisa → ukuhlolwa kwe-hydrostatic (noma ukutholwa kwamaphutha) → ukumaka → indawo yokugcina impahla.

Ipayipi lensimbi elibandayo elidonsayo (eligoqiwe) elingenamthungo: ishubhu eliyindilinga alinalutho → ukushisisa → ukubhoboza → isihloko → ukucwiliswa → ukucosha → ukugcoba → ukugcoba (i-copper plating) → ukudweba okubandayo okudlula okuningi (ukugoqa okubandayo) → ishubhu elingenalutho → ukwelashwa kokushisa → ukuqondisa → ukuhlolwa kwe-hydrostatic (iphutha ukutholwa) → ukumaka → indawo yokugcina impahla.
