Ukusebenza Kokushisa Okuphezulu
Ipayipi le-P92 liyaziswa ngenxa yamandla aphezulu okukhukhuleka, ukumelana nokushiswa kwe-oxidation kanye nokuqina kwesikhathi eside ekusetshenzisweni kwezinga lokushisa eliphakeme. Ukwakheka kwalo kwe-alloy ye-9Cr equkethe i-tungsten kuyenza ifanelekele izinhlelo zokusebenza zesiteshi sikagesi ezithuthukisiwe kanye nebhoyila lapho kuhlanganiswa khona izinga lokushisa eliphezulu kanye nokucindezela okuphezulu.
Ukushisela
Ukushisela i-P92 kudinga izinqubo zokushisela ezifanele, ukushisa okulawulwayo kwangaphambili, izinga lokushisa elilawulwayo le-interpass kanye nokwelashwa okufanele kokushisa ngemva kokushisela. Ukufaneleka kwenqubo yokushisela, ukukhethwa kwensimbi yokugcwalisa kanye nokulawula ubulukhuni kubalulekile ukuze kuqinisekiswe isevisi.
Ukwelashwa Kokushisa
Ipayipi le-P92 livame ukulethwa lisesimweni esijwayelekile nesifudumele ngokwezidingo zemininingwane. Ukwelashwa kokushisa okungalungile noma ukushisela imijikelezo yokushisa kungathinta amandla, ubulukhuni kanye nokusebenza kokushelela, ngakho-ke ikhodi efanele kanye nencazelo yephrojekthi kufanele ilandelwe.
Ukwakha Nokwakha Imishini
Ukusika, ukugoba kanye nokwakhiwa kwamapayipi kungenziwa ngokwemidwebo yephrojekthi. Ukuze kufakwe amapayipi okucindezela, ukubekezelela ubukhulu, ukulungiswa kwe-bevel, ukulandeleka kwenombolo yokushisa kanye nokuhlolwa kokugcina kufanele kulawulwe ngaphambi kokushisela noma ukufaka.
Kungani Ukhetha I-SAKY STEEL?
