Cov pa roj carbonhlau flangehais txog cov khoom siv hluav taws xob ntawm cov ntsiab lus carbon ntawm cov hlau, thiab feem ntau tsis ntxiv ntau cov ntsiab lus ntawm cov hlau, qee zaum kuj hu ua cov pa roj carbon steel lossis carbon hlau. Cov pa roj carbon steel, tseem hu ua carbon steel, hais txog cov ntsiab lus carbon ntawm WC yog tsawg dua 2% ntawm cov hlau carbon hlau.

Hlau phaj yuav tsum tau kuaj xyuas ultrasonic, tsis muaj delamination; Nws yuav tsum tau txiav mus rau hauv ib daim hlab raws li dov cov kev taw qhia ntawm hlau, thiab welded rau hauv rings los ntawm khoov, thiab ua rau saum npoo ntawm steel nplhaib cylindrical. Hlau phaj yuav tsum tsis txhob ncaj qha machined rau hauv caj dab flanges; Lub pob tw weld ntawm lub nplhaib yuav tsum yog tag nrho nkag mus rau weld; Kev siv cov pa roj carbon steel bolts tsis tas yuav tsum tau ntxiv rwb thaiv tsev gasket thiab chim, ntxiv rau cov rwb thaiv tsev gasket thiab lub thoob tsuas yog siv rau qhov muaj peev xwm xaiv tau los yog cov dej xa hluav taws xob yog cov nplaim taws thiab tawg, lub sijhawm no xaiv stainless hlau bolts kuj ntxiv cov rwb thaiv tsev gasket. thiab lub cev.
