DIN 17175 St45.8 boiler raj yog tsuas yog siv los tsim cov cua kub saum npoo ntawm cov cua kub qis thiab nruab nrab siab boilers, xws li cov phab ntsa dej txias, cov raj superheated, reheated steam tubes thiab economizer hlab.
St45.8 seamless raj feem ntau tuaj yeem tiv taus kev ua haujlwm siab tsis tshaj 5.88Mpa thiab tsim nyog rau kev ua haujlwm ib puag ncig nrog kev ua haujlwm kub hauv qab 450 degree.
DIN 17175 St45.8 steel tubes muab los ntawm GNEE txais yuav cov txheej txheem seamless ntau lawm los xyuas kom meej tias cov phab ntsa sab hauv thiab sab nrauv ntawm cov kav dej yog du thiab tsis muaj qhov tsis zoo, yog li kev txhim kho corrosion thiab kub tsis kam ntawm cov kav dej.
