GB/T9948-2013ʻO ka paipu kila seamless kahi paipu kila seamless kiʻekiʻe i hoʻohana kūikawā ʻia no ke kaʻina hana haki petroleum, a hoʻohana nui ʻia i nā lako koʻikoʻi e like me nā paipu umu, nā mea hoʻololi wela a me nā paipu kaomi i nā hale hoʻomaʻemaʻe aila. Hoʻoponopono pono kēia kūlana i nā koi mea hana, kaʻina hana a me ka hana o nā paipu kila e hōʻoia i kā lākou hana paʻa i nā wahi kiʻekiʻe-corrosion, kiʻekiʻe-mahana a me ke kaomi kiʻekiʻe.
2. Nā mea hana a me ka hana
1. Nā mea nui
GB/T9948-2013Hana ʻia nā paipu kila seamless mai nā ʻano mea metala like ʻole, e like me:
Ke kila kūkulu kalapona:20G, 20MnG, 25MnG
Ke kila kūkulu metala:15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB
Ke kila kila a me ke kila kūpaʻa wela: 1Cr18Ni9, 1Cr18Ni11Nb
2. Hana koʻikoʻi
Ke kūpaʻa wela kiʻekiʻe: Kūpono no nā kaʻina hana wela kiʻekiʻe e like me ka haki ʻana o ka petroleum (a hiki i ka 600°C a ʻoi aku paha).
Ke kūpaʻa kiʻekiʻe: Hōʻoia nā mea ikaika kiʻekiʻe i ka hana palekana o nā pipeline ma lalo o nā wahi kaomi kiʻekiʻe.
Ke kūpaʻa ʻana i ka palaho: Kūʻē maikaʻi nā ʻāpana metala kūikawā i nā mea ʻino e like me ka hydrogen sulfide a me ke kalapona ʻokikene.
Hilinaʻi kiʻekiʻe: Hōʻoia ka mana hoʻomalu maikaʻi loa e hoʻokō nā waiwai mechanical a me ka hoʻohui kemika o nā paipu kila i ke kūlana GB / T9948.
3. Ke kaʻina hana hana
Hoʻopuka ʻia nā paipu kila humuhumu GB/T9948-2013 e ka ʻōwili wela a me ke kahakiʻi anu (ʻōwili):
Ke kaʻina hana ʻōwili wela: ʻōwili paipu poepoe → hoʻomehana → perforation → ʻōwili → nui → hoʻoluʻu → hoʻopololei → nānā maikaʻi → mālama.
Ke kaʻina hana kaha anu (ʻōwili): perforation → pickling → kaha anu → mālama wela → hoʻopololei → ʻike kīnā → māka → mālama.
Hoʻomaopopo nā kaʻina hana ʻelua i ka pololei kiʻekiʻe o ka dimensional, ka ʻili laumania a me nā waiwai mechanical maikaʻi loa o nā paipu kila.
4. Nā kahua noi
Hoʻohana nui ʻia nā paipu haki petroleum GB/T9948 i:
ʻOihana petrochemical: ʻāpana haki, reactor hydrogenation, lako hana hoʻoponopono catalytic
ʻOihana hoʻomaʻemaʻe ʻaila: nā paipu umu wela kiʻekiʻe, nā mea hoʻololi wela, nā paipu kaomi kiʻekiʻe
Ka halihali kinoea kūlohelohe: nā paipu hoʻoili kinoea kūpaʻa i ka palaho, kiʻekiʻe ke kaomi
Hana ʻana i ka paila: nā paila kikowaena mana, nā ʻōnaehana paipu paila ʻoihana
5. Nā manaʻolana mākeke
Me ka wikiwiki o ka hoʻomohala ʻana o ka ʻoihana petrochemical kūloko a me ka ulu ʻana o ke koi o ka mākeke honua, ke piʻi mau nei ka nui o ke kūʻai aku ʻana o nā paipu kila humuhumu GB/T9948. ʻO kona kūpaʻa maikaʻi loa i ke anuanu kiʻekiʻe a me ke kūpaʻa i ka palaho e lilo ia i mea paipu makemake nui ʻia ma nā kahua o ka haki ʻana a me ka hoʻomaʻemaʻe ʻana i ka ʻaila.
6. Nā akahele no ke kūʻai ʻana a me ka hoʻohana ʻana
Koho mea paʻa: E koho i ka mea kūpono GB/T9948 (e like me 12CrMoG, 15CrMoG, a pēlā aku) e like me nā kūlana hana (mahana, kaomi, corrosionness).
Palapala hōʻoia maikaʻi: E hōʻoia i ka hoʻokō ʻana o ka paipu kila i ke kūlana GB/T9948-2013 a hāʻawi i kahi hōʻike nānā ʻaoʻao ʻekolu.
Ke kau ʻana a me ka mālama ʻana: E hōʻalo i ka hōʻino mechanical i ka wā o ka halihali a me ke kau ʻana, a e nānā pinepine i ka pala o ka pipeline a me nā kūlana kaomi.
Ua lilo ka paipu haki ʻaila GB/T9948-2013 i koho kūpono no ka petrochemical, hoʻomaʻemaʻe, kinoea kūlohelohe a me nā ʻoihana ʻē aʻe ma muli o kona mau pono o ke kūpaʻa wela kiʻekiʻe, ke kūpaʻa kiʻekiʻe a me ke kūpaʻa i ka pala. ʻO ke koho ʻana i nā mea kūpono (e like me 12CrMoG, 15CrMoG, a pēlā aku) a me ka hahai pono ʻana i nā kūlana hiki ke hōʻoia i ka hana palekana a paʻa o ka pipeline i ka wā lōʻihi.
Nā huaʻōlelo koʻikoʻi:#Paipu haki ʻaila, #GB/T9948, #GB/T9948-2013 paipu kila humuhumu ʻole, #Paipu kila haki ʻaila, #12CrMoG, #15CrMoG, #Paipu kila wela kiʻekiʻe a me ke kaomi kiʻekiʻe, #Paipu petrochemical
