P275NH chitsulo

EN 10028 P275NH/NL1/NL2
275NH ndi chitsulo chowotcherera bwino-tirigu choyenera kupanga zombo zoponderezedwa za mpweya woponderezedwa ndi mankhwala, ma boiler a mafakitale, ma compressor ndi osinthanitsa kutentha. Gululi limapangidwa kuti lizigwiritsidwa ntchito pazapakati mpaka kutentha kwambiri.

Mitundu ina yamakalasi ndi...
NL1 - ndi yabwino kuti igwiritsidwe ntchito kutentha kochepa
NL2 - ndiyoyenera kugwiritsidwa ntchito makamaka potentha kwambiri

Gnee steel imapereka P275NH kuchokera ku katundu ndikukubweretserani. Ma mbale athu a kaboni amayesedwanso kuti akhale okhwimitsa kwambiri zomwe zimapangitsa kuti masheya athu akhale okulirapo ndikuwonetsetsa kuti mumatumizidwa mwachangu.
