Kev tshuaj xyuasButtress Xov (BTC)yog ib txoj hauv kev tseem ceeb los xyuas kom meej cov txheej txheem kev ncaj ncees ntawm casing hauv qhov tob lossis siab - nro qhov dej. Tsis zoo li round threads (LTC / STC), Buttress threads muaj cov duab trapezoidal, xav tau cov cuab yeej tshwj xeeb thiab cov txheej txheem uas tau teev tseg los ntawmAPI Spec 5B.
Visual Thread Inspection (VDI)
Ua ntej siv cov ntsuas ntsuas, ua qhov kev kuaj pom zoo.
Qhov Defects:Saib rau "galling" (scratched / torn hlau), pits, xeb, los yog burrs.
Xov Form:Xyuas kom meej tias tsis muaj "tawg" lossis "mashed" threads, tshwj xeeb tshaj yog nyob rau thawj peb cov xov pib.
Qhov chaw "Run-out":Ntawm cov yeeb nkab (pin kawg), Buttress threads ploj mus rau hauv cov yeeb nkab lub cev. Xyuas tias qhov "khiav- tawm" thaj chaw no yog du thiab tsis muaj cov cuab yeej sib sib zog nqus.
Dimensional Measurement (Lub "Peb Loj")
API 5B yuav tsum ntsuas peb lub cev tshwj xeeb uas siv cov ntsuas ntsuas tshwj xeeb:
Lead (Pitch):Siv aLead Gaugelos ntsuas qhov kev ncua deb ntawm ib lub xov tooj mus rau lwm qhov dhau ntawm 1-nti ntu.
Vim li cas: Txhawm rau kom cov xov yuav kab zoo kawg nkaus nrog kev sib txuas.
Taper:Siv aSab nrauv / Internal Taper Gaugelos ntsuas qhov hloov ntawm txoj kab uas hla raws qhov ntev ntawm cov xov.
Yog vim li cas: Buttress threads yog tapered (1:16). Yog hais tias lub taper tsis ncaj ncees lawm, kev sib txuas yuav xoob dhau los yog yuav tsis ntsia hlau nyob deb txaus.
Xov Height:Siv aXov Height Gaugenrog ib tug ntse taw tes ntsuas qhov deb ntawm lub crest (sab saum toj) mus rau hauv paus (hauv qab).
Vim li cas: Qhov siab tsis raug ua rau cov khoom xa tawm tsis zoo thiab muaj peev xwm rub tawm - tawm.
Gauging Standoff (Tus "Master" Check)
Qhov no yog qhov kev sim zaum kawg kom paub meej tias cov xov raug txiav kom raug qhov loj.
Rau tus Pin (Pipe End):Ntsia rau ntawm ib qhoAPI Ua Haujlwm Ring Gauge(tes-tight). Ntsuas qhov deb ntawm qhov me me ntawm qhov ntsuas mus rau qhov kawg ntawm cov yeeb nkab. Qhov no yog hu uaStandoff.
Rau lub thawv (Coupling):Siv ibAPI Ua Haujlwm Plug Gauge.
Pass/Fail:Kev ntsuas yuav tsum poob rau hauv qhov kev zam tshwj xeeb uas tau teev tseg hauv API 5B cov lus rau cov yeeb nkab loj.
Daim duab peb sab Mark (Tshwj xeeb rau BTC)
Ntawm Buttress casing, aDaim duab peb sab Markyog stamped rau ntawm cov yeeb nkab kawg.
Daim tshev:Thaum lub sijhawm tshuaj xyuas, xyuas kom meej tias daim duab peb sab nyob ntawm qhov chaw API cov lus qhia.
Lub hom phiaj:Thaum lub sij hawm kev teeb tsa (ua- nce), lub ntsej muag ntawm qhov sib txuas yuav tsum xaus rau ntawm lub hauv paus lossis apex ntawm daim duab peb sab. Yog tias daim duab peb sab nyob rau hauv qhov tsis ncaj ncees lawm, cov neeg coob yuav dhau - zawm lossis qis dua - zawm cov yeeb nkab.
Profile Template Check
Siv aButtress Profile Gauge(ib daim hlau me me nrog cov xov zoo li txiav tawm).
Daim tshev:Muab tso rau hauv cov xov thiab tuav nws mus rau ib lub teeb.
Yuav nrhiav dab tsi:Yuav tsum tsis muaj teeb pom kev sib txawv ntawm qhov ntsuas thiab cov xov. Qhov no lees paub cov ces kaum ntawm "load flank" thiab "stab flank" yog lawm.
Daim ntawv teev npe rau Inspectors
| Parameter | Cov cuab yeej siv | API Requirement |
| Pom kev | Qhov muag / Magnifying iav | Tsis muaj galing, xeb, los yog mashed threads |
| Coj | Lead Gauge | Qhov tseeb hauv ± 0.002 txog 0.003 nti |
| Taper | Taper Gauge | Yuav tsum ua raws li 0.0625 nti / nti nqes hav |
| Qhov siab | Xov Height Gauge | Nws txawv ntawm cov yeeb nkab loj (feem ntau yog 0.062 ") |
| Standoff | Ntiv nplhaib / Plug Gauge | Yuav tsum phim API 5B Standoff Tables |
| Kev sib tw | Profile Template | Tsis muaj teeb ci; cov ces kaum yuav tsum muaj tseeb |

FAQ
Puas yog BTC txuas roj- nruj rau siab - cov qhov dej siab?
Txheem BTC yog rau cov kua / kua sealing. Yog tias qhov project cuam tshuam rau siab - pa roj, qhiaBTC nrog lub nplhaib fooblos yog aKev sib txuas hwm hwmnrog ib tug hlau - mus rau - hlau foob.
Dab tsi yog qhov kev kho deg rau cov couplings? Puas yog Manganese Phosphated?
Paub meej tias cov couplings tau dhau losManganese Phosphating. Qhov no txo kev sib txhuam, tiv thaiv galling, thiab pab cov xov compound (pipe dope) ua raws li zoo dua.
Koj puas muab cov khoom hnyav-cov khoom tiv thaiv? Kuv txhawj xeeb txog xov puas thaum lub caij hla hiav txwv.
Guarantee sivHlau -Plastic Composite Protectors. Cov no yog tsim los tiv thaiv cov dej hiav txwv ntev thiab kev tuav ntau yam ntawm qhov chaw nres nkoj.
