ʻO ke kiʻekiʻe kiʻekiʻe a me ke kūʻana:
ʻO A216 WCB e hoʻoikaika i ka hanaʻana i nā mahana kiʻekiʻe a me nā koi,
Ke kūpono nei ia no nā noiʻenehana koʻikoʻi e like me nā Valves a me nā moku ikaika kahi e maʻamau ai nāʻano.
Nā mea hana maikaʻi loa:
Hāʻawi ia i kahi hui kūpono o ka ikaika, kumaikalua, a me ka, e hiki ai i nā'āpana ke me nā ukana, kūkaʻi kū i ka hōʻoia, a me ka hana ikaika ikaika.
Noho mau kēia mau waiwai ma waena o kahi ākea ākea ākea, Ke hōʻoia nei i ka hana hilinaʻi.

No ka cryogenic a iʻole nā noi-wela, nā mea'ē aʻe (e like me A352 LCB) a iʻole e koi pinepineʻia nā lako wela.
ʻO ka hanaʻana i nā pilikia:
Ke koi neiʻo Welding A216 WCB i ka mālamaʻana ma muli o ka pilikia o ka paʻakikī a me ka hukiʻana i ka wahi wela (Haz).
Manaihi, ʻO ka hana wela wela (Pwht), a me ka nānā ponoʻana i nā metala fluler a me nā mea e pono ai nā papa hana, ka hoʻohuiʻana i ka paʻakikī a me ka uku i ka hana a me nā hoʻoponopono.

He aha ka mea a Astm A216 Sign WCB?
Astm A216 Sigle WCBʻO WCB kahi i hoʻohana pinepineʻia i keʻano crael crael cheel e hoʻohana maʻamau no nā kino valve, KahawaiOli, a me ka hoʻoikaikaʻana i nā'āpana i hoʻolālāʻia no ka maʻalahi o ka mahana kiʻekiʻe a me ka lawelawe.
He aha ka mea o WCB i ka helu kila?
Nā WCB e kū ai no ka "hana carbon b-papa,"E hōʻike ana i kahi māka cheal ceel cheal stella ceel cheel ma lalo o ka andm a216 me nā mea hoʻohuihui i weheweheʻia.
ʻO A216 WCB i pepehiʻia i ke kila ceel?
ʻAe, ʻO A216 WCB ka mea maʻamau i kahi kila kila, ʻO keʻano he piha piha i ka wā o ka steelmaking e pale ai i ka poosity space and hoʻomaikaʻi i ke kani.
He aha nā mea likeʻole A216?
Nā mea like like me ka Astm A352 LCB no nā noi haʻahaʻa haʻahaʻa a me ka Astm A105 no ke kila carbon, ʻOiai he105 he mau hiʻohiʻona mechanical likeʻole a he meaʻoleʻia ma mua o ka hoʻoleiʻana.
ʻO A216 WCB i hana a hoʻolei paha?
ʻO A216 WCB kahi kila carbon call, ua hanaʻia e nā kaʻina hana e like me ke kauʻana o ka sanding.
He aha ka mea hao wcb?
ʻO ka mea haoʻo WCB e pili ana i ka carbon solel milo i kohoʻia e like me wcb ma lalo o A216, Hoʻohana nuiʻia no ka hanaʻana i nā mea hana cat ceel i nā helu a me nā noi noi.
