Pup Joint yog dab tsi?
A Pup Jointyog ib qho khoom siv siv los kho tag nrho qhov ntev ntawm txoj hlua tubular (tubing, casing, lossis laum yeeb nkab) mus rau qhov tob tob. Txij li cov txheej txheem API cov yeeb nkab txuas feem ntau tuaj yeem ntev ntawm 28-32 ko taw (Range 2), cov pob qij txha pup - uas luv dua - tso cai rau cov kws ua haujlwm "qhov chaw tawm" txoj hlua kom cov khoom xws li cov packers lossis lub taub hau hangers zaum ntawm qhov xav tau qhov tob.

Classifications thiab Definitions
Pup pob qij txha feem ntau yog cais raws li hom hlua uas lawv txuas nrog:
Tubing Pup Joints:Siv nyob rau hauv cov tubing ntau lawm kab los pab txhawb cov ndlwg ntawm cov roj thiab roj los ntawm lub reservoir mus rau saum npoo.
Casing Pup Joints:Siv nyob rau hauv txoj hlua casing los kho txoj hauj lwm ntawm casing hangers los yog cov cuab yeej zoo.
Drill Pipe Pup Joints:Siv nyob rau hauv Lub Qhov Rooj Sib Tham Hauv Qab (BHA) los kho qhov hnyav - ntawm - ntsis lossis txoj haujlwm tshwj xeeb drilling cov cuab yeej.
Cov lus piav qhia ntxaws ntxaws
Txawm hais tias luv luv hauv qhov ntev, cov menyuam pob qij txha yog tsim los rau tib cov qauv nruj raws li tag nrho - ntev kav (API 5 CTlos yog API 5DP):
Khoom siv thiab lub zog:Pup pob qij txha yuav tsum tau ua los ntawm tib qib steel (piv txwv li, J55, N80, L80, P110) raws li tus so ntawm txoj hlua kom ntseeg tau tias cov khoom siv dag zog (lub zog tensile, lub cev tsis muaj zog, thiab tawg siab) tau zoo sib xws.
Kev tsim khoom:Lawv feem ntau yog machined los ntawmSeamless (SML)cov kav hlau. Cov xov raug txiav siv cov tshuab CNC precision kom ntseeg tau siab -kev ua tau zoo roj- nruj lossis kua- nruj seals.
Kev kho deg:Txhawm rau tiv thaiv corrosion thiab xov "galling" thaum pleev, xov yog feem ntauphosphatelos yog tooj liab -plated. Sab nrauv yog coated nrog xeb-cov xim tiv thaiv thiab cim nrog cov xim API tsim nyog.
Core Functions:
Kev kho qhov tob:Muab cov packers, twj, lossis sensors ntawm qhov tseeb geological qhov tob.
Wellhead Alignment:Xyuas kom lub sab saum toj sib koom ua ke ntawm txoj hlua mus txog qhov chaw ntawm qhov siab uas yuav tsum tau txuas mus rau tsob ntoo Christmas lossis BOP.
Kev Tswj Kev Nyuaj Siab:Ua haujlwm raws li kev hloov pauv lossis "tsis" ntawm cov khoom sib txawv ntawm txoj hlua.
