Ua lilo nā paipu wiliwili kila kila i mea pono loa ma nā ʻāpana ʻoihana like ʻole, mahalo i ko lākou kūpaʻa ʻana i ka pala, ka ikaika, a me ka hilinaʻi i nā wahi koʻikoʻi. ʻAʻole e like me nā paipu i hoʻopili ʻia, hana ʻia nā ʻano wiliwili me ka ʻole o nā hui, e hopena ana i ka hoʻonohonoho like a me nā waiwai mechanical i hoʻonui ʻia. Ke nānā nei kēia ʻatikala i nā kūlana hoʻokō honua nui e hoʻomalu ana i nā paipu wiliwili kila kila kila, me ka nānā hohonu ʻana i kā lākou laulā noi ākea.
Nā Kūlana Hoʻokō o nā Paipu Seamless Steel
Hana ʻia nā paipu wili ʻole kila kila e hoʻokō i nā kūlana honua a me nā kūlana aupuni paʻa. Ho'ākāka kēia mau kūlana i ka haku mele kemika, nā waiwai mechanical, nā ʻae ʻana o ka dimensional, a me nā ʻano hoʻāʻo e pono ai e hōʻoia i ka maikaʻi a me ka hana like o ka huahana. ʻO kekahi o nā kūlana i hahai pinepine ʻia:
● ASTM A312 / A312M
Uhi ke kūlana ASTM A312 i nā paipu kila kila austenitic seamless, straight-seam welded, a me nā paipu kila kila austenitic i hana anu ʻia no ka lawelawe wela kiʻekiʻe a me ka corrosive maʻamau. Hoʻohana nui ʻia ia i nā ʻoihana petrochemical a me ka hana mana.
E ʻimi:Paipu kila kila 304
● ASTM A213
Hoʻohana ʻia no ka paila hao hao ferritic a me austenitic seamless, superheater, a me nā paipu hoʻololi wela. Hoʻomalu ia i nā paipu hana kiʻekiʻe no ka ikehu wela a me nā mea kanu mana.
E ʻimi:Paipu kila kila 316L

He kūlana Kina kēia e wehewehe ana i nā paipu kila kila humuhumu ʻole i hoʻohana ʻia no ka lawe ʻana i ke wai. Hoʻoikaika ia i ka maʻemaʻe a me ke kūpaʻa i ka pala i nā ʻoihana meaʻai, kemika, a me nā lāʻau lapaʻau.
● EN 10216-5
He kūlana ʻEulopa e uhi ana i nā paipu kila kila humuhumu ʻole no nā kumu kaomi. Pili ia i nā paipu wela kiʻekiʻe a me ke kaomi kiʻekiʻe i nā ʻōnaehana ikehu a me nā ʻōnaehana mechanical.
● JIS G3459
Pili kēia kūlana Kepanī i nā paipu kila kila no nā paipu maʻamau. Hoʻohana pinepine ʻia ia i nā ʻōnaehana ʻoihana a me nā ʻōnaehana kūlanakauhale.
E ʻimi:Paipu kila kila 321 | Paipu kila kila 310/310S
Hōʻoia kēia mau kūlana ʻaʻole wale ka pololei o ke ana akā ʻo ke ʻano like hoʻi o ke kūpaʻa ʻana i ka pala, ka ikaika tensile, a me ke kūpaʻa ʻana i nā mahana kiʻekiʻe, e kūpono ai nā paipu no nā noi koʻikoʻi.
Ka laulā o ka noi o nā paipu kila kila ʻole
1. ʻOihana ʻAila a me ke Kinoea
He mea nui nā paipu wili ʻole kila kila i nā hana ma uka, waena, a ma lalo. Mai nā kahua wili a hiki i nā hale hoʻomaʻemaʻe, hiki i kēia mau paipu ke kū i nā kaomi koʻikoʻi a me nā wahi ʻino me ka mālama liʻiliʻi.
• Hoʻohana ʻia i loko o nā paipu wai ma lalo o ka moana, ka lawe ʻana i ka ʻaila, a me nā laina hoʻokomo kemika.
• Hāʻawi nā papa e like me 316L a me 904L i ke kūpaʻa chloride kiʻekiʻe.
E aʻo hou aku:Paipu kila kila 904L
2. Nā Hale Hana Kemika a me Petrochemical
Hoʻoili nā paipu kila kila ʻole i nā mea ʻino loa e like me ka waikawa sulfuric, chlorides, a me nā kemika pH kiʻekiʻe. Makemake ʻia nā papa e like me 304, 316L, a me 310S ma muli o ko lākou inertness kemika a me ke kūpaʻa wela.
• Hoʻohana ʻia i loko o nā mea hoʻololi wela, nā reactors, a me nā kolamu distillation.
• ʻAʻohe humuhumu wili = emi nā wahi nāwaliwali ma lalo o ke kaumaha a i ʻole ka pala.
3. Nā Hana Mana a me nā Mea Hoʻololi Wela
I loko o nā ʻōnaehana wela kiʻekiʻe e like me nā mea kanu mana nukelea, thermal, a me ka lā, hana nā paipu kila kila ma lalo o ke kaʻapuni thermal a me nā mea hoʻonāukiuki. ʻO ka hoʻokō ʻana o ASTM A213 a me EN 10216-5 e hōʻoiaʻiʻo i ke kūpaʻa o ke kaomi kiʻekiʻe a me ka mahana.
• Kūpono no nā paipu paila, nā paipu hoʻomehana hou, a me nā ʻōnaehana condensate.
• ʻOi aku ka maikaʻi o ke kila kila 310S i nā wahi i maʻalahi i ka oxidation.
E kipa aku:Paipu kila kila 310/310S
4. Nā ʻOihana Meaʻai a me nā Lāʻau Lapaʻau
He mea koʻikoʻi ka maʻemaʻe i kēia mau ʻoihana. Hoʻopau nā paipu wili ʻole kila i ka haumia o ka wili ʻana, e hōʻoiaʻiʻo ana i nā ʻili o loko a me ke kūʻē ʻana i ka biofouling.
• Hoʻokomo pū ʻia nā noi me nā lako hana waiū, nā laina hana mea inu, a me ka hana ʻana i nā lāʻau lapaʻau.
• ʻO nā kūlana e like me GB/T 14976 a me ASTM A270 ka mea i kuhikuhi pinepine ʻia.
E nānā:Paipu kila kila 316L
5. ʻEnekinia Moana
Pono ka ʻoihana moana i nā hoʻonā paipu ikaika e hakakā ai i ka palaho wai paʻakai ikaika. Hāʻawi nā paipu kila kila ʻole, ʻoiai nā papa duplex a me 904L, i ka hana lōʻihi ma nā wahi i piholo ʻia a me nā wahi pīpī.
• Hoʻokomo pū ʻia nā noi me nā ʻōnaehana ballast, nā ʻāpana desalination, a me nā kahua ma waho o ke kai.
6. Ke Kūkulu ʻana a me ka ʻenekinia kūkulu hale
Hoʻokomo nui ʻia ke kila kila no ka ikaika a me nā kumu nani i nā ʻōnaehana hoʻolālā hale a me nā ʻōnaehana kūkulu. Ua koho ʻia nā paipu humuhumu no nā hana hāpai ukana, nā ʻauamo lima, a me nā paia pale ma muli o ko lākou mau laina maʻemaʻe a me ke kūpaʻa i ka pala.
E nānā:Paipu kila kila 304
No ke aha e koho ai iā mākou i nā paipu kila kila ʻole?
Hāʻawi ʻo Sakysteel i kahi papa inoa piha o nā paipu kila kila ʻole ma nā ʻano papa like ʻole a me nā nui, e kūlike ana i nā kūlana honua nui. Me nā lako hana holomua a me ka kaohi maikaʻi koʻikoʻi, hōʻoia ʻo Sakysteel:
• Nā ʻae ʻana i ka nui paʻa
• Nā hoʻopau ʻili kūikawā
• Ke kūpaʻa kiʻekiʻe loa i ka pala a me ke kaomi
• Hoʻouna wikiwiki a me ka hana maʻamau
Hoʻokolokolo pono ʻia kēlā me kēia huahana e ka hoʻāʻo PMI, ka hoʻāʻo hydrostatic, ka ʻike ʻana i nā kīnā ultrasonic, a me nā nānā ʻana i nā dimensional.
