Nā mea hoʻohana pahu ʻaila:

Hoʻohana nui ʻia no ka luawai ʻaila i ke kaʻina wili a ma hope o ka pau ʻana o ke kākoʻo o ka pā luawai, i mea e hōʻoia ai i ke kaʻina hana wili a me ka hana maʻamau o ka pūnāwai holoʻokoʻa ma hope o ka hoʻopau ʻana. ʻO kekahi kumu, hiki ke alakaʻi i ka hoʻoemi ʻana o ka pūnāwai holoʻokoʻa, a i ʻole ka ʻōpala.

Nā ʻano o ka pahu aila:

Wahi a SY/T6194-96 "petroleum casing", hiki ke hoʻokaʻawale ʻia i ʻelua mau ʻano: ka pahu wili pōkole a me kona kola a me ka pahu wili lōʻihi a me kona kola.

ʻO ka maʻamau o ka pahu ʻaila a me ka hoʻopili:

Wahi a SY / T6194-96, pono e hoʻopaʻa ʻia ka pahu hale me ke kaula kila a i ʻole ke kāʻei kila.

E hoʻolako ʻia ka pahu me ka milo a me ke kola e like me ka API SPEC 5CT1988 paʻi mua a i ʻole ma kekahi o nā ʻano hopena paipu ma lalo nei: ka hopena palahalaha, ke kaula poepoe me ka ʻole o ke kola a i ʻole ke kola, offset thread trapezoidal me ka ʻole a i ʻole ke kola, ke kaula pololei, ka hana hoʻopau kūikawā, hana apo apo.

Papa kila no ka pahu aila:

Hiki ke hoʻokaʻawale ʻia ka papa kila casing aila i nā māka kila like ʻole e like me ka ikaika o ke kila ponoʻī, ʻo ia hoʻi H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110, Q-125, etc.ʻOkoʻa nā kūlana maikaʻi, hohonu hohonu, ʻokoʻa ka hoʻohana ʻana i ke kila kila.

Penei ka helu helu paona o ka pahu aila:

KG/ m = (ka anawaena o waho – mānoanoa pā) * mānoanoa pā *0.02466

Ka lōʻihi o ka pahu aila:

ʻEkolu ʻano lōʻihi i kuhikuhi ʻia e API: R-1 4.88 a 7.62m, R-2 7.62 a 10.36m, R-3 10.36m a lōʻihi.

ʻO ke ʻano o ka pahu pahu ʻaila:

API 5CTʻO nā ʻano ʻano pahu pahu pahu ʻaila he STC (puʻupuʻu pōkole pōkole), LTC (puʻupuʻu pōʻai lōʻihi), BTC (puʻu ʻāpana ʻāpana), VAM (kiʻi kiʻi) a me nā ʻano ʻāpana ʻē aʻe.

Nānā hana kino o ka pahu ʻaila:

(1) Wahi a SY / T6194-96. No ka hoʻokō ʻana i ka hoʻāʻo hoʻāʻo ʻana (GB246-97) hoʻāʻo tensile (GB228-87) a me ka hoʻāʻo hydrostatic.

(2) hydrostatic test, flattening test, sulfide stress corrosion cracking test, hardness test (ASTME18 or E10 latest version), tensile test, transverse impact test (ASTMA370, ASTME23 a me ka mea hou loa o nā kūlana kūpono) e like me nā ʻōlelo a ka American Petroleum Institute APISPEC5CT1988 determination first edition of1 grain 2 (ASTME version first ok)

Hoʻokomo a hoʻokuʻu aku i ka ʻaila pahu:

(1) ʻO nā ʻāina hoʻokomo nui o ka pahu aila: Kelemānia, Iapana, Romania, Czech Republic, Italia, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore.ʻO nā kūlana lawe mai e pili ana i ka American Petroleum Institute standard API5A, 5AX, 5AC.Steel grade is H-40, J-55, N-80, P-110, C-75, C-95 and so on.The main specifications are 139.77.72R-2, 177.89.19R-2, .2944R-2, . 244.510.03R-2, 244.511.05r-2, etc.

(2) Aia ʻekolu ʻano o ka lōʻihi i kuhikuhi ʻia e API: ʻo R-1 ka 4.88 ~ 7.62m, ʻo R-2 ka 7.62 ~ 10.36m, ʻo R-3 ka 10.36m a lōʻihi.

(3) Ua kaha ʻia kekahi hapa o nā waiwai i lawe ʻia mai me ka LTC, ʻo ia hoʻi, ka lima filament buckle.

(4) Ma waho aʻe o nā kūlana API, kahi helu liʻiliʻi o ka bushing i lawe ʻia mai Iapana e hoʻokō i nā kūlana o nā mea hana Iapana (e like me Nippon Steel, Sumitomo, Kawasaki, etc.), nā helu kila he NC-55E, NC-80E, NC-L80, NC-80HE, etc.

(5) Ma nā hihia koi, aia nā hemahema e like me ka ʻeleʻele ʻeleʻele, ka pōʻino o ke kaula uwea, ka pelu ʻana i ke kino o ka paipu, ka haki ʻana a me ke kaula paʻa i waho o ka hoʻomanawanui, ka hoʻopili ʻana i ka waiwai J ma waho o ka hoʻomanawanui, a me nā pilikia o loko e like me ka haki ʻana a me ka ikaika haʻahaʻa o ka pahu.

Nā waiwai mīkini o kēlā me kēia papa kila o ka pahu ʻaila:
