Paipu Humuhumu Pololei Kalapona

ʻO ka mea i hoʻohana ʻia no ka paipu kila kila humuhumu pololei he kila kalapona, ʻo ia hoʻi ke kila hao-kalapona me ka nui o ke kalapona oemi ma mua o 2.11%.Ma keʻano laulā, aia kahi liʻiliʻi o ka silicon, manganese, sulfur, a me ka phosphorus i loko o ke kila kalapona ma waho aʻe o ke kalapona.

Ma keʻano laulā, ʻo ke kiʻekiʻe o ka nui o ke kalapona i ke kila kalapona, ʻoi aku ka paʻakikī a me ke kiʻekiʻe o ka ikaika, akā ʻoi aku ka haʻahaʻa o ka plasticity.

Hiki ke hoʻokaʻawale ʻia nā paipu kila humuhumu pololei kila kalapona i nā paipu kila humuhumu pololei kiʻekiʻe a me nā paipu kila humuhumu pololei i hoʻopaʻa ʻia i lalo o ka wai e like me ke kaʻina hana. Ua māhele ʻia nā paipu kila humuhumu pololei i hoʻopaʻa ʻia i lalo o ka wai i nā paipu kila UOE, RBE, JCOE, a pēlā aku e like me kā lākou ʻano hana like ʻole.

Nā kūlana hoʻokō nui o ka paipu kila humuhumu pololei kila kalapona

GB/T3091-1993 (paipu kila welded galvanized no ka hoʻoili wai haʻahaʻa)

GB/T3092-1993 (paipu kila welded galvanized no ka hoʻoili wai haʻahaʻa)

GB/T14291-1992 (paipu kila i hoʻopili ʻia no ka lawe ʻana i ka wai o kaʻu)

GB/T14980-1994 (Nā paipu kila uila nui-anawaena no ka halihali wai haʻahaʻa)

GB/T9711-1997[Nā paipu kila hoʻoili ʻoihana ʻaila a me ke kinoea kūlohelohe, me GB/T9771.1 (e hōʻike ana i ke kila papa A) a me GB/T9711.2 (e hōʻike ana i ke kila papa B)]

Hoʻohana nui ʻia nā paipu kila humuhumu pololei kila kalapona i nā papahana hoʻolako wai, ʻoihana petrochemical, ʻoihana kemika, ʻoihana mana uila, hoʻoinu wai mahiʻai, a me ke kūkulu ʻana i ke kūlanakauhale. Hoʻohana ʻia no ka halihali wai: hoʻolako wai a me ka hoʻokahe wai. No ka halihali kinoea: kinoea, mahu, kinoea petroleum wai. No nā kumu kūkulu: e like me nā paipu pou, e like me nā alahaka; nā paipu no nā uapo, nā alanui, nā hale kūkulu, a pēlā aku.
