Kev faib tawm los ntawm Xov Hom (API Rotary Shouldered Connections)
Qhov no yog qhov kev faib ua feem ntau siv rau hauv qhov chaw rig, tsom rau kev sib raug zoo ntawm txoj kab nruab nrab (ID) ntawm kev sib koom tes thiab tus ID ntawm cov yeeb nkab lub cev.
IF (Internal Flush):
Nta:Tus ID ntawm cov cuab yeej sib koom ua ke yog raws li tus ID ntawm cov yeeb nkab chim siab thiab lub cev yeeb nkab.
Qhov zoo:Nws muaj qhov tsawg kawg nkaus tsis kam rau cov kua dej drilling, uas ua rau lub zog hydraulic tsawg tsawg.
Daim ntawv thov:Feem ntau siv hom. Niaj hnubNC (Numbered Connection)series zoo li NC38 thiab NC50 feem ntau hloov pauv tau nrog IF.
REG (Regular):
Nta:Sab hauv txoj kab uas hla ntawm qhov sib koom ua ke yog me dua li tus ID ntawm cov yeeb nkab lub cev.
Qhov zoo:Nws muaj cov phab ntsa tuab tshaj plaws, muab kev ua haujlwm siab tshaj plaws.
Daim ntawv thov:Feem ntau siv raudrill bits, crossover subs, thiab cov cuab yeej nuv ntses; nws tsis tshua muaj siv rau lub ntsiab laum yeeb nkab hlua.
FH (Full Hole):
Nta:Qhov sib koom ID yog nyob nruab nrab ntawm IF thiab REG, tsim kom muaj ib qho profile sab hauv.
Daim ntawv thov:Ib qho qauv qub uas tau hloov pauv los ntawm NC series niaj hnub hauv kev ua haujlwm drilling tam sim no.
API Drill Pipe Kev Sib Txuas Hom (RSC)
Cov lus no hais txog cov xov tsim ntawm lubCov cuab yeej sib txuaswelded mus rau qhov kawg ntawm lublaum cev.
| Hom kev sib txuas | Sib npaug NC | TPI (Thread Per Inch) | Taper | Tsim nta (ID vs. Pipe ID) | Cov ntawv thov tseem ceeb |
| IF (Internal Flush) | NC26, NC31, NC38, NC50 | 4 | 1:6 | Flush Bore:Joint ID=Siab ID=Pipe Body ID | Kev lag luam Standard.Tsawg khiav tsis kam; max hydraulic zog. |
| REG (Regular) | - | 4o5 ib | 1:4o 6 | Contracted Bore:Joint ID yog me dua li Pipe ID | Drill Bits, Crossover Subs, thiab cov cuab yeej nuv ntses (Thickest phab ntsa). |
| FH (Full Hole) | NC40, NC 46 | 4 | 1:4 | Stepped Bore:ID yog nruab nrab ntawm hom IF thiab REG | Legacy drilling rigs; loj hloov los ntawmNCseries. |
Classification los ntawm Upset Type
Qhov no yog hais txog yuav ua li cas qhov kawg ntawm cov yeeb nkab lub cev yog thickened ua ntej cov cuab yeej pob qij txha yog welded rau:
IU (Internal chim):
Cov yeeb nkab sab nraud txoj kab uas hla (OD) tseem nyob tas li thaum lub phab ntsa thickness nce nyob rau hauv. Qhov no ua rau cov kua dej ntau dua tab sis ua kom lub ntsej muag du.
EU (Sab nraud chim):
Cov yeeb nkab sab hauv txoj kab uas hla (ID) tseem nyob tas li thaum phab ntsa thickness nce sab nraud. Qhov no muab kev sib txuas siab zog tab sis ua rau muaj qhov loj dua sab nrauv ntawm cov pob qij txha.
IEU (Internal & External chim):
Ob tus ID thiab OD yog thickened. Qhov no yog qhovfeem ntau niaj hnub txoj kev, raws li nws muab qhov zoo tshaj plaws sib npaug ntawm kev sib txuas lub zog thiab cov kua dej ntws zoo.
Drill Pipe Upset Hom (API 5DP)
Cov lus no hais txog lub cev thickening ntawm lubLub cev lub cevxaus ua ntej welding cov cuab yeej pob qij txha.
| Txaus siab Code | Lub Npe | Internal Diameter (ID) Hloov | Sab nraud Diameter (OD) Hloov | Core Zoo |
| IU | Internal chim | Ua me (Internal phab ntsa thickened) | Tseem nyob tas li | Smoo sab nrauv; zoo tagnrho rau nruj- kev ua haujlwm tshem tawm. |
| EU | Sab nraud chim | Tseem nyob tas li | Ua loj dua ( Sab nrauv phab ntsa thickened) | Kev sib txuas siab zog; xoom hauv dej obstruction. |
| IEU | Internal & External chim siab | Ua me me | Ua loj | Feem ntau hom.Qhov zoo tshaj plaws sib npaug ntawm tensile lub zog thiab ntws efficiency. |

FAQ
Class 2 laum yeeb nkab yog dab tsi?
Class 2 laum yeeb nkab yog hais txog siv cov yeeb nkab laum nrog cov phab ntsa seem ntawm qhov tsawg kawg yog 65% ntawm cov phab ntsa qub. Unilateral hnav yog tso cai; Txawm li cas los xij, tag nrho cov ntoo khaub lig- ntu ntu yuav tsum sib npaug ntawm qib hwm, sib haum rau cov phab ntsa tuab tuab tsis tshaj 20%.
Ntev npaum li cas yog ib qho kev sib txuas ntawm cov yeeb nkab tho?
Tus qauv ntev ntawm ib leeg tho yeeb nkab sib koom ua ke feem ntau nyob ib ncig ntawm 9 meters; qhov no yog qhov tshwj xeeb tshaj plaws hauv kev ua haujlwm roj drilling thiab ntog hauv 9-10 meter ntau yam pom zoo los ntawm API cov qauv.
Hauv kev ua haujlwm hauv thaj chaw tiag tiag, cov kav dej laum txuas nrog ib qho los ntawm ib qho -hauv cov chav nyob hu ua "joints"- thiab qis rau hauv qhov dej. Peb qhov ntev tshaj plaws yog 6 meters, 9 meters, thiab 12 meters; ntawm cov no, 9-meter ntev yog cov qauv siv dav tshaj plaws, raws li nws ua rau muaj kev sib npaug ntawm kev ua haujlwm zoo thiab kev sib txuas ruaj khov ntawm lub taub dej.
