Ntchito zopangira mafuta:

Ntchito pobowola mafuta chitsime zimagwiritsa ntchito pobowola ndondomeko pobowola ndi pambuyo akamaliza chitsime thandizo khoma, pofuna kuonetsetsa ndondomeko pobowola ndi ntchito yachibadwa chitsime lonse pambuyo completion.Chifukwa cha zinthu zosiyanasiyana zachilengedwe, mobisa nkhawa boma ndi zovuta, ndi zochita zonse za kumakokedwa, compressive, kupinda ndi torsional kupsyinjika pamwamba pa chitoliro lokha amaika kupsyinjika pamwamba pa chitoliro pawokha. imawonongeka chifukwa chazifukwa zina, imatha kupangitsa kuti chitsime chonsecho chichepetse, kapenanso zinyalala.

Mitundu ya botolo la mafuta:

Malinga ndi SY/T6194-96 "petroleum casing", ikhoza kugawidwa m'mitundu iwiri: chokopa chachifupi chokhala ndi ulusi ndi kolala yake ndi casing yayitali ndi kolala yake.

Muyezo wa posungira mafuta ndi ma CD:

Malingana ndi SY/T6194-96, chotchinga chapakhomo chiyenera kumangiriridwa ndi waya wachitsulo kapena lamba wachitsulo. Mbali yowonekera ya casing iliyonse ndi ulusi wa kolala iyenera kukulungidwa ndi mphete yotetezera kuteteza ulusi.

Chophimbacho chidzaperekedwa ndi ulusi ndi kolala molingana ndi API SPEC 5CT1988 kope loyamba kapena mumtundu uliwonse wa mapeto a chitoliro: mapeto athyathyathya, ulusi wozungulira wopanda kolala kapena kolala, kuchotsa ulusi wa trapezoidal kapena wopanda kolala, ulusi wowongoka, kukonza kwapadera kwapadera, kumanga mphete yosindikizira.

Chitsulo chachitsulo chamafuta a petroleum:

Oil casing zitsulo kalasi akhoza kugawidwa m'magulu osiyanasiyana zitsulo malinga ndi mphamvu ya zitsulo palokha, ndicho H-40, J-55, K-55, N-80, C-75, L-80, C-90, C-95, P-110, Q-125, etc.Kusiyanasiyana kwabwino, kuya kwakuya, kugwiritsa ntchito kalasi yachitsulo kumakhalanso kosiyana.Chombocho chimafunikanso kuti chisawonongeke m'malo owononga.M'malo omwe ali ndi zovuta za geological, casing imafunikanso kugonjetsedwa ndi kuphwanya.

Njira yowerengera kulemera kwa chosungira mafuta ndi motere:

KG/ m = (m'mimba mwake wakunja - makulidwe a khoma) * makulidwe a khoma * 0.02466

Utali wa botolo la mafuta:

Pali mitundu itatu yautali wotchulidwa ndi API: R-1 4.88 mpaka 7.62m, R-2 7.62 mpaka 10.36m, R-3 10.36m mpaka kutalika.

Mtundu wa buckle wa petroleum:

API 5CTMitundu ya zomangira zamafuta a petroleum imaphatikizapo STC (chingwe chozungulira chachifupi), LTC (chingwe chozungulira chachitali), BTC (chomangira chapang'ono cha makwerero), VAM (king buckle) ndi mitundu ina.

Kuyang'anira magwiridwe antchito a petroleum casing:

(1) Malinga ndi SY/T6194-96.Kuchita mayeso a flattening (GB246-97) tensile test (GB228-87) ndi hydrostatic test.

(2) hydrostatic test, flattening test, sulfide stress corrosion cracking test, hardness test (ASTME18 kapena E10 latest version), tensile test, transverse impact test (ASTMA370, ASTME23 and the latest version of the relevant standards) malinga ndi zomwe American Petroleum Institute APISPEC5CT1988 , determination1 version yaposachedwa ya mbewu ya OstME2 njira)

Kulowetsa ndi kutumiza kunja kwa botolo la mafuta:

(1) Mayiko ofunikira kwambiri opangira mafuta ndi awa: Germany, Japan, Romania, Czech Republic, Italy, United Kingdom, Austria, Switzerland, United States, Argentina, Singapore komanso kuitanitsa.Miyezo yolowera ku American Petroleum Institute standard API5A, 5AX, 5AC.Steel giredi ndi H-40, J-55, N-80, P-110, C-75, C-95 ndi zina zotero.Mafotokozedwe akuluakulu ndi 139.77.72R-2, 177.89.294-4. 244.510.03R-2, 244.511.05r-2, ndi zina zotero.

(2) Pali mitundu itatu yautali wotchulidwa ndi API: R-1 ndi 4.88 ~ 7.62m, R-2 ndi 7.62 ~ 10.36m, R-3 ndi 10.36m kutalika.

(3) Gawo lazinthu zomwe zatumizidwa kunja zimalembedwa ndi LTC, mwachitsanzo, malaya amtundu wa filament.

(4) Kuphatikiza pa miyezo ya API, chiwerengero chochepa cha bushing chomwe chimatumizidwa kuchokera ku Japan chimatsatira miyezo ya opanga ku Japan (monga Nippon Steel, Sumitomo, Kawasaki, etc.), manambala achitsulo ndi NC-55E, NC-80E, NC-L80, NC-80HE, etc.

(5) Pazifukwa zodzinenera, panali zolakwika zowoneka ngati zakuda zakuda, kuwonongeka kwa tayi, kupindika kwa thupi la chitoliro, chitsulo chosweka ndi ulusi wotalikirana ndi kulolerana, kugwirizanitsa mtengo wa J chifukwa cha kulolerana, ndi zovuta zamkati zamkati monga kusweka kwa brittle ndi mphamvu zochepa zokolola za casing.

Makina amtundu uliwonse wazitsulo zamafuta amafuta:
