P460NH Pressure Vessel Steel Plate

P460NH, yomwe imatchedwanso kukhala ndi mphamvu zokolola zochepa za 460 MPa, ndi gawo lapamwamba kwambiri lachitsulo chotengera chitsulo chomwe chimagwiritsidwa ntchito popanga boiler komanso kupanga zotengera zokakamiza. Ndi chitsulo chabwino chambewu chokhazikika chokhala ndi mikhalidwe yabwino yowotcherera.

Mitundu ina ya giredi ikuphatikiza…
NL1 - ndi yabwino kuti igwiritsidwe ntchito kutentha kochepa
NL2 - ndiyoyenera kugwiritsidwa ntchito makamaka potentha kwambiri

P460NH imagwiritsidwanso ntchito popanga gasi wowawasa pomwe chitsulocho chidzayesedwa HIC kuyesa kutha kwa zinthu kung'aluka kopangidwa ndi haidrojeni.
