P460NH Umuvuduko w'icyuma Icyuma

P460NH, byitwa rero kugira imbaraga nkeya yumusaruro wa MPa 460, nicyiciro cyiza cyumuvuduko wicyuma cyicyuma kugirango ukoreshwe mubihimbano no mu bwato. Nicyuma gisanzwe cyiza cyicyuma gifite imiterere myiza yo gusudira.

Ubundi bwoko bw'amanota burimo…
NL1 - nibyiza gukoreshwa mubushyuhe buke
NL2 - nibyiza gukoreshwa cyane cyane ubushyuhe buke

P460NH ikoreshwa kandi mubisabwa gaze ya gaz aho ibyuma bizaba HIC Bipimwa kugirango bipime ibikoresho byoroshye hydrogène iterwa no guturika.

EN 10028-3 P460NH Ibyapa byerekana:
Umubyimba: 6mm kugeza 300mm
Ubugari: 1500mm kugeza 4050mm
Uburebure: 3000mm kugeza 15000mm
