Khoom Paub meej
Stellite alloy valve lub tes tsho yog siv dav hauv kev lag luam roj av drilling. Kev ua haujlwm ib puag ncig thiab cov xwm txheej ntawm kev lag luam roj av drilling yog qhov hnyav heev. Tshwj xeeb tshaj yog, dej, ntau yam roj, siv quav ciab, xuab zeb thiab lwm yam khoom muaj corrosive feem ntau muaj nyob rau hauv cov xuab zeb ua qhov dej, cov roj qhov dej hnyav thiab cov dej muaj zog los tiv thaiv cov roj condensate. Cov roj twj tso kua mis yuav tsum tau muab cov roj los ntawm kev tsim ntau pua lossis ntau txhiab meters sib sib zog nqus, uas ua rau cov kev cai nruj ntawm lawv cov khoom rau kev ua tau zoo sealing, hnav tsis kam thiab corrosion kuj. Stellite alloy valve lub tes tsho tsim los ntawm atmospheric siab precision casting, nqus precision casting thiab hmoov metallurgy txheej txheem tuaj yeem ua tau raws li cov kev pabcuam hnyav saum toj no.
Daim ntawv thov teb
Stellite alloy valve lub tes tsho yog tsuas yog siv rau hauv li qub xws li pob li qub, roj twj tso kua mis li qub thiab cov kua dej li qub.
