Ke hilinaʻi nei mākou i ka ikaika ʻenehana paʻa a hoʻomau i ka hana ʻana i nā ʻenehana paʻakikī e hoʻokō i ka koi o Kina Manufacturer no ka ASTM A335 Heat-Resisting Seamless Alloy Steel Pipe, Hāʻawi mākou i ka mea nui i ka leʻaleʻa kiʻekiʻe a me ka leʻaleʻa o ka mea kūʻai aku a no kēia mea mākou e hahai ai i nā ana hoʻomalu maikaʻi maikaʻi. Loaʻa iā mākou nā keʻena hoʻāʻo i loko o ka hale kahi e hoʻāʻo ʻia ai kā mākou hoʻonā ma kēlā me kēia ʻaoʻao ma nā pae hana like ʻole. No ka loaʻa ʻana o nā ʻenehana hou loa, hoʻomaʻamaʻa mākou i kā mākou mea kūʻai aku me ka hale hana hoʻopuka maʻamau. ʻO ka inoa ʻoihana, e pili mau ana i ka maikaʻi e like me ke kumu o ka ʻoihana, e ʻimi ana i ka hoʻomohala ʻana ma o ka hilinaʻi kiʻekiʻe, e mālama pono ana i ke kūlana hoʻokele ISO maikaʻi, e hoʻokumu i ka ʻoihana kiʻekiʻe e ʻuhane o ka holomua - hōʻailona i ka ʻoiaʻiʻo a me ka manaʻolana.
Aia ka hoʻokomo ʻana o T91/P91 alloy steel boiler pipe
1. Hoʻolauna Papa kila
T91 / P91 mea he ferritic wela kila, e ka oak ridge national laboratory ma 1970 s hoomaka e noiʻi a me ka ulu ana, a ma 1983 ma ASME, ko kakou aina ma 1995 i ke kila i loko o ka GB 5310 maʻamau, brand like me ka 10 cr9mo1vnbT91 / P91 kila he 9 cr1mo (T9), ma ke kumu o ke kila, ka maemae, maikai crystallization metallurgy enehana, a me ka micro alloying a me ka hoʻomalu 'olokaʻa a me ka hoomalu ana 'enehana, ua hoʻomohala i ka hou hanauna o ka wela pale kila kila. Loaʻa i ke kila nā waiwai mechanical piha maikaʻi, ʻelemakule wela kiʻekiʻe ma hope o ka paʻa ʻana, a maikaʻi ka hana kuʻi ʻana a me ka hana kaʻina hana, kūpono no ke kiʻekiʻe wela o ka ʻāpana o nā mea.
