I kēia manawa,12Cr1MoV Paipu kila ʻoleua hoʻohana nui ʻia i ka Superheater, ke poʻo a me ke kahe mahu nui o ke kiʻekiʻe kiʻekiʻe, ke kiʻekiʻe kiʻekiʻe a me ka subcritical power station boilers ma ka home a ma waho.Ua lilo kēia kila i mea nui o ka mea kanu mana a me ka paila ma ka ʻoihana mana o Kina.
I kēia manawa,12Cr1MoV Paipu kila ʻolehoʻohana nui ʻia ma nā ʻano aʻe:
(1) Hoʻohana nui ʻia no ka paipu superheater, paipu ea, paipu mahu nui, paipu reheater a me nā ʻāpana ʻē aʻe o nā lako paila, ʻoi aku ka nui o ka puʻu kiʻekiʻe a me ka ultra-high-pressure boiler, 12Cr1MoVG haʻahaʻa haʻahaʻa haʻahaʻa mehana pale kila.
(2) Hoʻohana nui ʻia no ke kumu nui,] impeller, rotor, fastener (bolt and nut), cylinder, nozzle chamber, lubricating valve, diaphragm a me kekahi mau mea lau o ka turbine mahu.
(3) Hoʻohana nui ʻia e hoʻemi i ka mahana hana o ka rotor a me ka lau i loko o ka mīkini kinoea wela a hiki i 550 ℃, i mea e hoʻonui ai i ka noi o ke kila wela wela i loko o ka mīkini kinoea.
(4) Hiki ke hoʻohana ʻia e hana i ka rotor turbine gas, impeller, fastener a me nā ʻāpana ʻē aʻe me ka mahana hana ma lalo o 570 ℃.
(5) Hoʻohana nui ʻia no ka hana ʻana i ka paipu umu ahi, ka mea hoʻololi wela a me nā paipu wela ʻē aʻe i nā mea kemika a me ka ʻaila.
