Yog vim li cas qhov kawg hom yog ib tug cais Ordering khoom
API Spec 5CT npog casing, tubing thiab coupling Tshuag, thiab nws kho cov yeeb nkab lub cev thiab qhov kawg mob raws li ob halves ntawm ib yam khoom. Lub cev yog txhais los ntawm sab nraud txoj kab uas hla, phab ntsa thickness, steel qib thiab ntev ntau yam; qhov kawg yog txhais los ntawm daim ntawv xov, coupling thiab machining ntawm cov yeeb nkab kawg. Kev txiav txim los ntawm qib ib leeg tawm ntawm kev sib koom ua ke tsis tau txhais, uas yog vim li cas qhov kawg yam tshwm sim ntawm txhua kab ntawm kev txiav txim tubular. Qhov ntsuas tensile ntawm txoj hlua yog teem los ntawm qhov tsis muaj zog ntawm cov yeeb nkab lub cev thiab kev sib txuas.
Xov Ranges npog los ntawm API Spec 5CT
| Hom kawg | Kev piav qhia | Cov kev pabcuam |
|---|---|---|
| STC | Short round thread casing nrog coupling | Lub qhov dej ntiav, lub teeb loads |
| LTC | Ntev round xov casing nrog coupling | General casing Service |
| BTC | Buttress los yog stepped xov casing nrog coupling | Qhov dej tob, siab axial load |
| NU | Tsis yog - chim siab tubing | Nruab nrab dai load |
| EU | Sab nraud chim siab tubing nrog EUE xaus | hnyav loads, nquag tuav |
| IJ | Integrally txuas tubing | Txo coupling sab nraud txoj kab uas hla |
| XC | Ncaj los yog hwm kev sib txuas casing | Tshwj xeeb clearance thiab sealing xav tau |
Xov qhov ntev rau tag nrho cov ntaub ntawv no tau muab rau hauv API Spec 5B, thaum cov khoom xav tau rau cov khoom sib txuas thiab cov yeeb nkab lub cev tau muab rau hauv API Spec 5CT.
Coupling txoj kab uas hla thiab sawv ntsug -Tawm kev tshuaj xyuas
Thaum casing yog threaded los ntawm ib tug ua cov nroj tsuag es tsis yog los ntawm cov yeeb nkab zeb, lub sib dhos sib dhos yog soj ntsuam rau txoj kab uas hla ntawm ib tug taag deb ntawm qhov kawg ntawm lub coupling, thiab lub ntsuas yuav tsum tau pom zoo nrog tus nqi tabulated rau qhov luaj li cas. Kev ntsuas yog coj los ntawm lub zog- nruj sib koom ua ke, vim tias ib qho kev sib koom ua ke uas tsis tau ua tiav los ntsuas qhov loj thiab tus ntoo khaub lig- xov sib koom ua ke ntsuas me me. Stand-off yog nyeem tib lub sijhawm thiab qhia tias muaj kev koom tes ntau npaum li cas.
Tshawb xyuas txoj kab uas hla thiab sawv ntsug- tawm ntawm qhov ua- sib koom ua ke, tsis yog ntawm qhov sib txuas xoob.
Txheeb xyuas qhov sib txuas sab nraud txoj kab uas hla tawm tsam daim duab tabulated rau qhov loj thiab qhov hnyav.
Tsis lees txais cov pob qij txha uas nws sawv ntsug- tawm mus rau sab nraud ntawm qhov teev tseg, vim nws qhia tias cov xov puas lossis tsis sib haum.
Sau cov txiaj ntsig los ntawm tus lej xov tooj cua sov yog li tom qab tsis ua haujlwm tuaj yeem taug qab mus rau lub xov tooj ntawm tes.
Xim Xim thiab Cim Lub Cev
API Spec 5CT muab cov cim xim rau cov qib casing, tubing thiab coupling kom cov khoom tuaj yeem lees paub hauv lub vaj yam tsis tas txiav cov qauv. Cov yeeb nkab lub cev kuj yog ib qho stencil uas nws cov ntsiab lus thiab kev txiav txim raug kho. Cov kab ke sau los ntawm qhov ntev, qhov hnyav, zeb code, tus qauv, daim ntawv tso cai naj npawb, API monogram, hnub tsim khoom, specification, qib kev qhia, kev kho cua sov, txoj kev tsim khoom, cov kev xav tau ntxiv, hydrostatic test, xov hom, drift, furnace tooj, dov los yog kub kho batch thiab ceg los yog hloov tus naj npawb. Kev ua tiav tshwj xeeb yog cim nrog lub cim cais kom qhov sib koom ua ke nrog qhov tsis yog - tus qauv kawg yuav tsis ua yuam kev.
Ordering thiab Inspection Notes
Qhia qhov kawg hom, qhov ntev thiab seb cov couplings puas tau nkag nrog cov yeeb nkab thaum qhov kev nug raug tsa. Ntev ntev ua raws li R-1, R-2 thiab R-3 bands ntawm qhov tshwj xeeb, thiab cov qhab hloov ntau npaum li cas cov pob qij txha haum rau qhov kev pab cuam zoo. Ntawm daim ntawv txais nyiaj, txheeb xyuas cov stencil tiv thaiv daim ntawv pov thawj zeb, paub meej tias cov xim xim sib phim rau qib, thiab tawm cov xov tiv thaiv nyob rau hauv qhov chaw kom txog thaum txoj hlua npaj khiav.
FAQ
Q: Dab tsi yog hom kawg hauv API Spec 5CT?
Nws yog kev sib xyaw ua ke ntawm daim ntawv xov, lub coupling thiab machined yeeb nkab kawg. Qib txhais cov khoom siv, thaum kawg hom txhais li cas cov pob qij txha txuas.
Q: Cov xov twg yog API Spec 5CT npog?
Luv round thread casing, ntev round thread casing, buttress thread casing, non- chim siab tubing, sab nraud chim tubing, integrally txuas tubing thiab ncaj los yog hwm kev twb kev txuas casing.
Q: Qhov twg yog txoj kab uas hla tau soj ntsuam ntawm lub qhov sib txuas?
Ntawm qhov ua- sib koom ua ke, ntawm qhov ncua deb ntawm qhov kawg ntawm kev sib txuas, thiab qhov ntsuas yuav tsum pom zoo nrog tus nqi tabulated rau qhov loj ntawd.
Q: Puas muaj xim xim rau cov qib casing?
Yog lawm. Cov kev qhia tshwj xeeb muab cov cim xim rau cov qib casing, tubing thiab coupling, thiab cov xim yuav tsum pom zoo nrog qib stencilled ua ntej kev sib koom ua ke.
Q: Dab tsi yog qhov tshwj xeeb kawg ua cim cim?
Nws ceeb toom tias qhov kawg tau ua tiav dhau ntawm tus qauv yuav tsum tau ua, yog li kev sib koom ua ke yuav tsum tau ua thiab tshuaj xyuas rau cov lus qhia ntxiv uas tau muab nrog rau kev txiav txim.
