Ua lilo nā paipu kila kila i mea nui ma waena o kahi ākea ākea o nā ʻāpana ʻoihana, mahalo i ko lākou kūʻē ʻana i ka corrosion, ikaika, a me ka hilinaʻi i nā kaiapuni koʻikoʻi. ʻAʻole like me nā paipu welded, hana ʻia nā ʻano like ʻole me ka ʻole o nā hono, e hopena i ka ʻano like ʻole a me ka hoʻomaikaʻi ʻana i nā waiwai mechanical. Ke ʻimi nei kēia ʻatikala i nā kūlana hoʻokō honua nui e hoʻokele ai i nā paipu hili ʻole kila kila, me ka nānā hohonu i kā lākou hoʻohana ākea ākea.
Nā Kūlana Hoʻokō o nā Paipu Kūleʻa ʻole
Hoʻokumu ʻia nā paipu hili ʻole kila kila e hoʻokō i nā kūlana koʻikoʻi o ka honua a me ke aupuni. ʻO kēia mau maʻamau ka wehewehe ʻana i ka haku mele kemika, nā waiwai mechanical, ka hoʻomanawanui dimensional, a me nā ʻano hoʻāʻo e pono ai e hōʻoia i ka maikaʻi o ka huahana a me ka hana. ʻO kekahi o nā maʻamau i hahai pinepine ʻia:
● ASTM A312 / A312M
Hoʻopili ka maʻamau ASTM A312 i nā paipu kila austenitic kuhili ʻole, wili pololei, a me ka hana anu nui i manaʻo ʻia no ka lawelawe ʻana i ka wela kiʻekiʻe a me ka lawelawe corrosive maʻamau. Hoʻohana nui ʻia ia i nā ʻoihana petrochemical a me ka mana.
E ʻimi:304 Paipu Kūleʻa ʻole
● ASTM A213
Hoʻohana ʻia no ka paila ferritic a me austenitic alloy-steel boiler, superheater, a me nā paipu hoʻololi wela. Hoʻoponopono ia i nā paipu hana kiʻekiʻe no ka ikehu wela a me nā mea kanu mana.
E ʻimi:316L Paipu Kuhili ʻole
● GB/T 14976
He maʻamau Kina kēia e hōʻike ana i nā paipu kila kila ʻole i hoʻohana ʻia no ka lawe ʻana i ka wai. Hoʻoikaika ia i ka maʻemaʻe a me ka pale ʻana i ka corrosion i nā ʻoihana meaʻai, kemika, a me nā lāʻau lapaʻau.
● EN 10216-5
He maʻamau ʻEulopa e uhi ana i nā paipu kila kuhili ʻole no nā kumu kaomi. Hoʻopili ia i nā pipeline kiʻekiʻe-mehana a me ke kiʻekiʻe i ka ikehu a me nā ʻōnaehana mechanical.
● JIS G3459
ʻO kēia kūlana Iapana e pili ana i nā paipu kila kila no ka paipu maʻamau. Hoʻohana pinepine ʻia ia i nā ʻōnaehana maʻamau a me ke kaona.
E ʻimi:321 Paipu Kinohi ʻole | 310/310S ʻO ke kila kila maikaʻi ʻole
ʻAʻole kēia mau maʻamau e hōʻoiaʻiʻo i ka pololei o ka dimensional wale nō akā ke kūlike pū i ka pale ʻana i ka corrosion, ka ikaika tensile, a me ke kūʻē ʻana i nā wela kiʻekiʻe, e kūpono ana nā paipu no nā noi koʻikoʻi.
Hoʻohana i ka laulā o nā paipu kuhili ʻole
1. ʻOihana ʻaila a me nā kinoea
He mea nui nā paipu kila kila ma nā hana i luna, waena, a me lalo. Mai nā kahua hoʻoheheʻe ʻana a hiki i ka hoʻomaʻemaʻe ʻana, mālama kēia mau paipu i nā puʻupuʻu koʻikoʻi a me nā kaiapuni corrosive me ka mālama liʻiliʻi.
• Hoʻohana ʻia i loko o nā paipu ma lalo o ka moana, ka lawe ʻana i ka aila, a me nā laina hoʻoheheʻe kemika.
• Hāʻawi nā papa e like me 316L a me 904L i ke kūpaʻa chloride maikaʻi.
E aʻo hou aku:904L Kuhili ʻole ʻia ʻole
2. Nā mea kanu kemika & petrokimia
Lawe ʻia nā paipu kuhili ʻole i nā mea ʻino loa e like me ka sulfuric acid, chlorides, a me nā kinikona pH kiʻekiʻe. Loaʻa 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 nā mea hoʻololi wela, nā reactors, a me nā kolamu distillation.
• ʻAʻohe weld seam = liʻiliʻi nā wahi nāwaliwali ma lalo o ke koʻikoʻi a i ʻole ka pala.
3. Hoʻoulu mana a me nā mea hoʻololi wela
Ma nā ʻōnaehana wela kiʻekiʻe e like me ka nuklea, ka wela, a me nā mea kanu mana o ka lā, hana nā paipu kila kila ma lalo o ka paikikala wela a me ka pāpaʻi hoʻopaʻapaʻa. ʻO ka hoʻokō ʻana o ASTM A213 a me EN 10216-5 e hōʻoia i ka hoʻomau kiʻekiʻe a me ka hoʻomau wela.
• He kūpono no nā paipu paila, nā paipu wela, a me nā ʻōnaehana condensate.
• 310S kila kuhiliʻole maikaʻi i loko o oxidation-prone kaiapuni.
E kipa:310/310S ʻO ke kila kila maikaʻi ʻole
4. ʻOihana Meaʻai & Laʻau Laʻau
He mea koʻikoʻi ka maʻemaʻe ma kēia mau ʻoihana. Hoʻopau nā paipu kuʻi ʻole i ka weld contamination, e hōʻoiaʻiʻo ana i ka maʻemaʻe o loko a me ke kūpaʻa ʻana i ka biofouling.
• Loaʻa i nā noi nā mea hana waiu, nā laina hana inu, a me ka hana lāʻau.
• Hoʻohana pinepine ʻia nā kūlana e like me GB/T 14976 a me ASTM A270.
Hōʻoia:316L Paipu Kuhili ʻole
5. ʻEnekinia Moana
Pono ka ʻāpana kai i nā hoʻonā paipu ikaika e pale aku i ka ʻino wai paʻakai. ʻO nā paipu kila kila ʻole, ʻoi aku ka duplex a me nā māka 904L, e hāʻawi i ka hana lōʻihi ma nā ʻāpana i lalo a me ka splash.
• Loaʻa i nā noi nā ʻōnaehana ballast, nā ʻāpana desalination, a me nā paepae waho.
6. Kūkulu a me ka ʻenekinia hana
Hoʻohui nui ʻia nā ʻano hana hoʻolālā a me ka hoʻolālā ʻana i ke kila kila no ka ikaika a me ka nani. Ua koho ʻia nā paipu seamless no ka lawe ʻana i ka ukana, nā lima lima, a me nā pā pale ma muli o ko lākou mau laina maʻemaʻe a me ka pale ʻana i ka corrosion.
No ke aha e koho ai iā mākou i nā paipu ʻole kila kila?
Hāʻawi ʻo Sakysteel i kahi laina holoʻokoʻa o nā paipu kila kila ma nā ʻano like ʻole a me nā nui, e like me nā kūlana honua nui. Me nā lako hana kiʻekiʻe a me ka mana koʻikoʻi koʻikoʻi, hōʻoia ʻo Sakysteel:
• ʻO ka hoʻomanawanui ʻana o ka nui
• Hoʻopau ʻili maikaʻi
• 'Oi aku ka corrosion a me ke kaomi
• Hoʻouna wikiwiki a me ka hana maʻamau
Hoʻopili ʻia kēlā me kēia huahana i ka nānā koʻikoʻi me ka hoʻāʻo PMI, ka hoʻāʻo hydrostatic, ka ʻike flaw ultrasonic, a me nā loiloi dimensional.
