OCTG Casing Manufacturing Process|API 5CT Siab -Lub zog Oilfield Casing
Taw qhia rau API 5CT Standard
Casing thiab tubing nyob rau hauv ib tug roj & rojua haujlwm zoo li ib qho OCTG system. Covcasingcov hlua stabilize lub qhov, cais formations thiab tiv thaiv nto thiab av av, thaum lubcevmuab txoj hauv kev hloov pauv tau rau cov roj, roj lossis cov kua dej txhaj tshuaj. Thaum peb tsim ib qhoAPI 5CT casing thiab tubingqhov kev pab cuam, peb saib tag nrho txoj kev thauj khoom - tawg, tawg, nro thiab annular siab - yog li lub cev casing,
Octal Pipe ua haujlwm tshwj xeeb nrogAPI 5CT-licensed mills teev nyob rau hauv daim ntawv teev npe API Composite, guaranteeing traceable manufacturing, tshawb xyuas metallurgy, thiab ua tiav daim ntawv pov thawj ua raws liAPI 5CT (11th tsab)thiabAPI Q1 / ISO 9001: 2015kev tswj kom zoo.
Steel Qib thiab Mechanical Properties
API 5CT qib yog tsim los ua kom tau raws li ntau yam ntawm qhov dej zoo - los ntawm qhov tob, qis - cov roj qhov dej siab mus rau ultra- qhov tob HPHT roj.
Txhua qib muaj cov kev txwv tshwj xeeb rau kev tawm dag zog, lub zog tensile, thiab elongation, ua kom cov neeg kho tshuab ruaj khov nyob rau hauv compression, nro, thiab sab hauv siab.

Octal Pipe pab cov neeg ua haujlwm thiab EPCs nrogqib kev xaiv, kev sib tsoo thiab tawg tsis kam,thiabH₂S / CO₂ compatibility ntsuam xyuaskom ntseeg tau tias txhua txoj hlua ua tau raws li qhov project geological thiab tsim lub hnab ntawv.
API 5CT Casing thiab Tubing: Cov teeb meem ntawm thaj chaw cov neeg yuav khoom xav tiv thaiv
API 5CT casing thiab tubing kavtsis tau yuav "ua tau raws li tus qauv." Lawv tau yuav los ua kom muaj kev ruaj khov thiab ntws tawm - yam tsis muaj qhov xau, ntsaws ruaj ruaj, lub siab xav tsis thoob, lossis kev lees paubsuas tig mus rau downtime thiab rework.
Feem ntau ntawm cov nqi tsis yog los ntawm ib qho tsis ua haujlwm loj. Nws los ntawm kev twv ua haujlwm tau mob taub hau uas pib raws li qhov sib txawv me me ntawm PO.
1.Casing kev ncaj ncees thiab annular siab tsim-nce
Cov neeg ua haujlwm yuav pomtxawv txav annulus siab, sustained siab, los yog siab imbalance ntawm annuli. Cov txiaj ntsig yog feem ntauCov teeb meem kev ncaj ncees, kev sib cais tsis zoo, corrosion, lossis puas threads / couplings-thiab qhov teeb meem nce ntxiv vim nws dhau los ua kev cuam tshuam / kev sib raug zoo ntawm kev sib tham, tsis yog teeb meem ntau lawm.
2.Plug thiab txwv (wax/scale/sand/debris)
Thaum lub sijhawm nqa khoom lossis tsim khoom, kev txwv tsis pub tshwm simTus nqi poob qis, siab tsis ruaj khov, siab dua lub twj tso kua mis, lossis nquag ntxuav tawm. Lub hauv paus ua rau tsis tshua muaj "cov yeeb nkab zoo" ib leeg- nws yog kev sib xyaw ua ke ntawmFlow regime + deposits + internal roughness + khib nyiab tswj thiab huv.
3.Corrosion- tsav tsis ua hauj lwm (CO₂/H₂S, high chloride water cut)
Cov teeb meem Corrosion tsis zoo heev thaum tau txais. Lawv tshwm tom qab lipitting, to, thiab shortened khiav lub neej, tshwj xeeb tshaj yog nyob rau hauv qaub los yog ntub CO₂ kev pab cuam thaum metallurgy, hardness tswj, thiab soj ntsuam scope tsis meej sau rau hauv qhov kev txiav txim.
4.Ua- ncua sij hawm thiab hla- xov ntawm lub rig
Qhov tsis ua haujlwm kim tshaj plaws yog qhov tshwm sim thaum cov neeg ua haujlwm tos. Yog tias txoj hlua yuav tsis ua kom zoo, koj poob sijhawm sai. Tej yam ua rau:sib xyaw hom kev sib txuas, cov xov puas, cov ntaub ntawv pov thawj uas ploj lawm, lossis tsis paub meej qhov sib txuas.

Dab tsi koj tau txais nrog Octal Pipe
Octal Pipe ua haujlwm raws li Tuam Tshoj -raws li OCTG Casing thiab Tube chaw tsim tshuaj paus nrog cov tswv yim hauv zos kom zoo dua - nruj kev sib koom ua ke thoob cov yeeb nkab, threading thiab couplings, ntxiv rau lub Hoobkas- sab digital tswj kev cim, cov npe thiab kev taug qab- yog li cov pob casing tuaj txog khiav - kev tiv thaiv kev ncua thiab kev ncua ntawm rig.
Thaum koj yuavOCTG cev, "qhov zoo" tsis yog ib lo lus hais tias - nws yog tus neeg muag khoomkhoom siv thiab cov txheej txheem tswjtsis tu ncua tsim threads, couplings, thiab cov yeeb nkab lub cev uas dhau qhov kev lees txais thawj zaug. Nrog Octal Pipe, koj tau txais ib qho kev pab cuam tsim nyob ib ncig ntawm cov kauj ruam tswj tau thiab cov txiaj ntsig tau lees paub:
- Tswj threading ua rau rov ua dua -up:ntau lawm yog tsim nyob ib ncig ntawm kev ruaj ntseg threading kev coj ua thiab kev soj ntsuam rooj vag, yog li kev sib txuas koj xaj yog qhov kev sib txuas uas koj tau txais - txhawb nqa los ntawmxov gauging pov thawj thaum teev tsegthiab qhia meej txog kev sib txuas (STC/LTC/BTC; EUE/NUE; premium options).
- Couplings kho raws li ib feem tseem ceeb, tsis yog ib qho khoom siv:coupling processing yog tswj kom phim cov qib xaj thiab kev pabcuam, nrog rau cov chaw kuaj xyuas uas txo cov kev tsis txaus siab feem ntau hauv cheeb tsam -kev sib txuas- cuam tshuam txog kev tsis lees paub thiab kev hnav ntxov ntxov.
- Kev tshuaj xyuas muaj peev xwm ua tau raws li qhov tseeb ntawm qhov project:thaum koj PO/ITP hu rau nws, kev pov thawj tau ua tiav nrog cov txheej txheem teev tseg (txoj kev + kev pab them nqi + kev lees paub) thiab xa tawm raws li cov lus ceeb toom- yog li "NDT / hydrotest / drift" tsis yog cov lus lag luam tab sis ntsuas cov txiaj ntsig tau.
- Traceability ua rau hauv kev ua haujlwm:Thaum tshav kub kub/ntau daim ntawv qhia thiab cim yog nqa mus rau packing, thiab cov pob tso tawm (MTC 3.1/3.2, thib peb-kev soj ntsuam tog thaum xav tau) yog npaj rau QA/TPI tshuaj xyuas, tsis post- cov ntaub ntawv xa tuaj raws.
Ua haujlwm nrog Casing thiab Tubing Running Services tuam txhab
Feem ntau qeeb tshwm sim ntawm lub interface nrogcasing thiab tubing khiav kev pab cuam tuam txhab uas muag-tsis yog vim tias cov yeeb nkab qib tsis raug, tab sis vim tias txoj hlua tsis tuaj yeem tso tawm thiab ua haujlwm zoo: tally tsis phim cov pob khoom, xov tuaj txog qias neeg lossis puas tom qab rov ua dua - tuav, lossis drift / ua- qhov kev cia siab tsis tau kaw. Los ntawm kev pom kev yuav khoom, zooOCTG kav dej kev pabcuamnyob ntawm seb lub pob khoom puas tau teeb tsa rau rig- qhov tseeb hauv pem teb, tsis yog cov ntaub ntawv zeb xwb.
Octal Pipe tswj qhov kev xa khoom no ua ib feem ntawm kev xa khoom: kev xa khoom xa tuaj yog ntim thiab txheeb xyuas kom haum rau qhov kev sib tw khiav, cov xov raug tiv thaiv rau kev thauj mus los thiab kev txav mus los, thiab cov ntaub ntawv ntim tau npaj kom tau txais tuaj yeem tshem tawm ntau yam tsis muaj cov pov thawj uas ploj lawm. Lub hom phiaj yog qhov yooj yim-thaum cov neeg ua haujlwm khiav pib khaws cov pob qij txha, lawv tsis nres rov- xyuas IDs, rov- cov xov kom huv, lossis sib cav txog kev lees paub.
Ob yam los xauv rau ntawm PO (yog li cov neeg ua haujlwm khiav tsis poob sijhawm):
- Tally + txais kev qhuab qhia:Daim ntawv ID sib koom ua ke, kev sib koom ua ke, ntim khoom / kos npe sib dhos, thiab daim ntawv qhia kev taug qab (thaum teev hauv PO / ITP).
- Khiav-kev lees txais:drift lub hauv paus (API vs tshwj xeeb drift), hom kev sib txuas, thiab ib qho xov gauging / torque-tig pov thawj xav tau (thaum teev hauv PO/ITP).
OCTG Pipe Head Interface
- Casing thiab tubing head compatibility: Paub meej tias hanger thiab wellhead interface yuav tsum ntxov kom drift / ID thiab kev sib txuas xaiv tsis muaj teeb meem ntawm kev teeb tsa.
- Kev sib txuas thiab kev sib khi: Match OCTG yeeb nkab kev sib txuas hom rau lub taub dej thiab ua kom - xyaum ua kom tsis txhob xau thaum lub sij hawm siab - nce.
- Kev qhuab qhia hauv kev sib koom ua ke: Khaws cov khoom tiv thaiv thiab ntxuav cov xov los ntawm kev thauj mus los kom lub taub hau ua kom zoo- tsis txhob sib ntaus sib tua.
