Maikaʻi maikaʻi Kina ASTM A213 Alloy High Pressure Seamless Steel Grade T11 T12 T13 T22 T1 T2 Pipe/Tube
"ʻO kaʻoiaʻiʻo, ka hana hou, ka ikaika, a me ka maikaʻi" hiki ke hoʻomau i ka manaʻo o kā mākou ʻoihana i ka wā lōʻihi e hana pū me nā mea kūʻai aku no ka launa like ʻana a me ka loaʻa kālā no ka hāʻawi ʻana i ka hopena paipu. Loaʻa iā mākou i kēia manawa kahi waihona waiwai nui o Cr Mo alloy steel pipe e hoʻokō ai i kā mākou mea kūʻai aku a me nā pono. Me nā limahana i hoʻonaʻauao maikaʻi ʻia, noʻonoʻo a me ka ikaika, ua kuleana mākou no nā mea āpau o ka hāʻawi ʻana i ka hoʻonā paipu. Ma muli o ka waiwai kiʻekiʻe kiʻekiʻe a me ka lawelawe nui, ke hele nei mākou i ka pahuhopu e lilo i mea hoʻolako paipu nui loa ma ka honua. Hoʻolohe pono mākou i nā manaʻo mai kā mākou mea kūʻai aku a hāʻawi i nā pane koke. E ʻike koke ʻoe i kā mākou lawelawe akamai a hoʻolohe.
E pili ana i ka waiwai o ka paipu Cr Mo, nui nā mea metala e pili ana iā ia. ʻO ka pilina ma waena o ka pono mechanical o ka paipu a me ka mea metala nui e like me lalo:
Carbon (C): Hoʻonui ka ʻike kalapona i loko o ke kila, ka helu hua, ka ikaika tensile a me ka paʻakikī, akā e emi ana ka palaki a me nā waiwai hopena. Ke ʻoi aku ka nui o ke kalapona ma mua o 0.23%, ʻoi aku ka maikaʻi o ka hana kuʻi ʻana o ke kila, no laila inā hoʻohana ʻia no ka wili ʻana ʻAʻole ʻoi aku ka nui o ke kila kila haʻahaʻa haʻahaʻa ma mua o 0.20%. ʻO ka maʻiʻo kalapona kiʻekiʻe e hōʻemi i ka pale ʻana i ka corrosion o ke kila, a ʻo ke kila kiʻekiʻe-carbon i loko o ka pā hale kūʻai maʻalahi i ka pala; Eia kekahi, hiki i ke kalapona ke hoʻonui i ka brittleness anu a me ka naʻau kahiko o ke kila.
Silicon (Si): Hoʻohui ʻia ʻo Silicon ma ke ʻano he mea hoʻohaʻahaʻa a me ka deoxidizer i ke kaʻina hana kila, no laila ke kila i pepehi ʻia he 0.15-0.30% silika. Hiki i ka Silicon ke hoʻomaikaʻi maikaʻi i ka palena elastic, yield point a me ka ikaika tensile o ke kila, no laila ua hoʻohana nui ʻia e like me ke kila elastic. ʻO ka hoʻonui ʻana i ka nui o ka silika e hōʻemi i ka hana kuʻi ʻana o ke kila.
Manganese (Mn). I ke kaʻina hana kila, manganese he deoxidizer maikaʻi a me ka desulfurizer. ʻO ka maʻamau, loaʻa ke kila 0.30-0.50% manganese. Hiki i ka Manganese ke hoʻonui i ka ikaika a me ka paʻakikī o ke kila, hoʻonui i ka paʻakikī o ke kila, hoʻomaikaʻi i ka hana wela o ke kila, a hoʻemi i ka hana wili o ke kila.
Phosphorus (P): ʻO ka mea maʻamau, he mea ʻino ka phosphorus i ke kila, e hoʻonui ai i ke anuanu o ke kila, e hōʻemi i ka hana wili, e hōʻemi i ka plasticity, a e hōʻemi i ka hana anu. No laila, ʻoi aku ka liʻiliʻi o ka phosphorus ma ke kila ma lalo o 0.045%, a ʻoi aku ka haʻahaʻa o ke koi no ke kila kiʻekiʻe.
Sulfur (S): He mea ʻino ka Sulfur ma lalo o nā kūlana maʻamau. E hana i ke kila wela, e ho'ēmi i ka ductility a me ka ʻoʻoleʻa, a hana i nā māwae i ka wā o ka hana ʻana a me ka ʻōwili ʻana. Hoʻopilikia ka Sulfur i ka hana kuʻi ʻana, e hōʻemi ana i ka pale ʻana i ka corrosion. No laila, ʻoi aku ka liʻiliʻi o ka sulfur ma lalo o 0.045%, a ʻoi aku ka haʻahaʻa o ke koi no ke kila kiʻekiʻe. ʻO ka hoʻohui ʻana i ka 0.08-0.20% sulfur i ke kila hiki ke hoʻomaikaʻi i ka machinability, a ua kapa ʻia ʻo ia ke kila ʻoki manuahi.
ʻO Vanadium (V): Hiki i ka hoʻohui ʻana i ka vanadium i ke kila ke hoʻomaʻemaʻe i ka palaoa a hoʻomaikaʻi i ka ikaika a me ka paʻakikī.
Niobium (Nb): Hiki iā Niobium ke hoʻomaʻemaʻe i nā kīʻaha a hoʻomaikaʻi i ka hana wili.
Copper (Cu): Hiki i ke keleawe ke hoʻoikaika i ka ikaika a me ka paʻakikī. ʻO ka hemahema, ʻo ia ka maʻalahi i ka wela wela i ka hana wela, a ʻoi aku ka kiʻekiʻe o ke keleawe i loko o ke kila ʻōpala.
Aluminum (Al): ʻO ka alumini ka mea hoʻohana deoxidizer i ke kila. Hoʻohui ʻia kahi liʻiliʻi o ka alumini i ke kila e hoʻomaʻemaʻe i nā kīʻaha a hoʻomaikaʻi i ka paʻakikī o ka hopena.
