ʻIke maikaʻi no nā kumu kūʻai o 316 Stainless Steel Pipe - 254SMO UNS S31254 1.4547 stainless seamless pipe - Huaxin Detail:
1. wehewehe maʻalahi:
ʻO 254SMO kahi kila kila austenitic.
GB papa: 00Cr20Ni18Mo6CuN
Papa honua: 254SMO
Papa maʻamau ʻAmelika: UNS S31254
Papa EU: W. – Nr 1.4547
Nā kūlana ʻAmelika: ASTM A240/ASME SA-240, ASTM A276, ASTM A182/ASME SA-182, ASTM A312/ASME A312
Nui ka nui: 10*2mm a 219*15mm a i ʻole e like me ka makemake o ka mea kūʻai aku
Ka lōʻihi: 300mm a 20000mm

4. 254SMO wehewehe:
a. ʻO 254SMO he kila kuhiliʻole austenitic. Ma muli o kona kiʻekiʻe molybdenum maʻiʻo, he kiʻekiʻe kiʻekiʻe kona kūʻē ʻana i ka corrosion
a me ka ʻinoʻino o ka māwae.
b. Hoʻokumu ʻia kēia ʻano kila kila no ka hoʻohana ʻana i nā kaiapuni i loaʻa nā halides e like me ka wai kai. Loaʻa iā 254SMO ka maikaʻi
kū'ē i ka ʻānai like ʻole.
c. ʻOi aku ka nui o ka ʻakika i loko o ka halide, ʻoi aku ka maikaʻi o ke kila ma mua o ke kila kila maʻamau. ʻO ka maʻiʻo C he <0.03%, no laila ua kapa ʻia
kila kuhiliʻi austenitic maʻemaʻe (<0.01% ua kapa ʻia hoʻi ke kila kila ʻoi loa austenitic). ʻO ke kila kila kila keʻano o ke kila kila kūikawā.
d. ʻO ka mea mua, he ʻokoʻa ia mai ke kila kuhili ʻole maʻamau i ka haku melemele. E pili ana ia i ke ʻano o ke kila kila kila kiʻekiʻe
loaʻa ka nickel kiʻekiʻe, chromium kiʻekiʻe a me ka molybdenum kiʻekiʻe. ʻO ka mea kaulana loa ʻo 254SMo nona ka 6% Mo. ʻO kēia ʻano kila
loaʻa maikaʻi loa kūloko corrosion kū'ē.
e. Loaʻa iā ia ka pale corrosion pitting maikaʻi (PI ≥ 40) a me ke kūpaʻa corrosion koʻikoʻi ma lalo o nā kūlana o ke kai, aeration, crevice
a me ka haʻahaʻa māmā holo.
f. He mea pani ia no ka alloy Ni base a me ka titanium alloy. ʻO ka lua, ma ke ʻano o ke kūpaʻa wela kiʻekiʻe a i ʻole ke kūpaʻa corrosion,
ʻoi aku ka maikaʻi o ke kūpaʻa wela kiʻekiʻe a i ʻole ke kūpaʻa corrosion, ʻaʻole hiki ke hoʻololi ʻia no ka 304 stainless steel. Kahi mea hou aʻe,
mai ka hoʻokaʻawale ʻana o ke kila kila, ʻo ke ʻano metallographic o ke kila kila kūikawā he ʻano metala austenitic paʻa.
g. ʻOiai ʻo kēia kila kila kūikawā he mea hoʻoheheʻe kiʻekiʻe, ʻoi aku ka paʻakikī o kāna hana hana. ʻO ka maʻamau, hiki i nā kānaka ke hilinaʻi wale
nā hana kuʻuna no ka hana ʻana i kēia kila kila kūikawā, e like me ka ninini ʻana, ka forging, ka ʻōwili, etc.
5. Noi:
1) Nā moana: nā hale kai o ka moana kai, ka hoʻoheheʻe ʻana i ke kai, ka lawaiʻa, ka hoʻololi ʻana i ka wela o ke kai, etc.
2) Ka mālama ʻana i ke kaiapuni: ka mea hana desulfurization flue gas no ka hana ʻana i ka mana wela, ka mālama ʻana i ka wai ʻino, etc.
3) Energy: hana mana atomic, hoʻohana piha i ka lanahu, hana mana o ke kai, etc.
4) ʻOihana Petrochemical: hoʻomaʻemaʻe aila, mea hana kemika, etc.
5) kahua meaʻai: hana paʻakai, soy sauce brewing, etc.
6) Kaiapuni chloride kiʻekiʻe: ʻoihana pepa, nā ʻano hana bleaching like ʻole.
6. Hana hou aku:
1) Polani
2) Mākaʻikaʻi:
3) Hoʻopili:
7. Ke hoʻouka ʻana i ka pahu:
Nā kiʻi kikoʻī huahana:
Alakaʻi Huahana Pili:
Hoʻopili kā mākou hui i ke kumu kumu o "ʻO ka maikaʻi ke ola o ka ʻoihana, a ʻo ke kūlana paha ka ʻuhane o ia mea" no ka nānā ʻana i ka maikaʻi no 316 Stainless Steel Pipe Prices - 254SMO UNS S31254 1.4547 stainless seamless paipu – Huaxin, ʻO ka huahana. lako i ka honua holoʻokoʻa, e like me: Dominica, moldova, Somalia, E mālama ana i kā mākou motto o "Hoʻopaʻa maikaʻi i ka maikaʻi a me nā lawelawe, ʻoluʻolu nā mea kūʻai aku", No laila hāʻawi mākou i kā mākou mea kūʻai aku me nā huahana kiʻekiʻe a me nā hopena a me ka lawelawe maikaʻi loa. E ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no ka ʻike hou aku.
