DRILL PIPE PRODUCTION PROCESS

Drill pipe production process

APPLICATION

Laum yeeb nkab yog cov yeeb nkab steel nrog ib txoj xov ntawm qhov kawg. Nws yog tsuas yog siv los txuas cov cuab yeej saum npoo ntawm cov khoom siv drilling mus rau cov khoom siv drilling thiab sib tsoo lossis cov cuab yeej hauv qab hauv qab ntawm lub qhov dej drilling. Nws lub ntsiab daim ntawv thov thaj chaw muaj xws li:

Kev Tshawb Fawb Roj thiab Roj

rill yeeb nkab ua lub luag haujlwm tseem ceeb hauv kev tshawb nrhiav roj thiab roj, tshwj xeeb tshaj yog nyob rau hauv drilling thiab ua tiav cov haujlwm, muaj peev xwm tiv taus kev ntxhov siab, kub thiab loads.

Coal mines

Cov kav dej laum kuj tau siv dav hauv kev ua haujlwm drilling hauv cov mines thee.

Yuav tsum kuaj dab tsi ntawm cov yeeb nkab tho?

hydrostatictest
Hydrostatic test yog ib qho kev ntsuas siab uas feem ntau siv hauv cov txheej txheem ntawm cov kav dej. Qhov kev kuaj no yog siv los kuaj xyuas cov dej xau hauv cov welds lossis cov yeeb nkab lub cev. Txhawm rau ua qhov kev sim, dej tau muab tso rau hauv cov yeeb nkab kom txog thaum lub siab tau mus txog qhov siab. Tom qab ntawd saib xyuas cov kav dej kom xau. Yog tias pom tias muaj qhov xau, cov kav dej yuav tsum tau kho lossis hloov. Kev ntsuam xyuas hydrostatic yog ib qho tseem ceeb ntawm kev tswj xyuas zoo uas yuav pab kom muaj kev nyab xeeb thiab kev ncaj ncees ntawm cov kav dej.

Khoov xeem
Kev kuaj khoov yog qhov kev tswj xyuas zoo tau ua thaum lub sij hawm tsim cov yeeb nkab steel. Lub hom phiaj ntawm kev xeem yog los xyuas seb puas muaj cov kab nrib pleb hauv cov welds thiab ntsuas lub zog ntawm cov hlau. Txhawm rau ua qhov kev sim, tus qauv ntev ntawm cov yeeb nkab yog khoov rau hauv U-puab. Tom qab ntawd tshuaj xyuas cov hlau rau cov kab nrib pleb lossis lwm yam cim ntawm kev qaug zog. Yog tias pom, tag nrho cov kav hlau steel yuav raug muab pov tseg thiab ua ib pawg tshiab. Txawm li cas los xij, yog tias qhov kev sim khoov tau ua tiav, cov yeeb nkab steel yuav raug pom zoo siv.

Flatten xeem
Qhov kev sim flattening yog ib qho kev ntsuam xyuas cov yeeb nkab steel uas ntsuas cov yeeb nkab steel muaj peev xwm tiv taus deformation thiab tawg hauv kev ntxhov siab. Qhov no yog ib qho tseem ceeb tswj kev ntsuas uas pab xyuas kom meej tias cov hlau siv nyob rau hauv cov yeeb nkab cov khoom yog qhov zoo tshaj plaws. Qhov kev sim no muaj kev siv lub siab rau cov yeeb nkab steel kom txog thaum nws deforms lossis tawg. Cov kev ntsuam xyuas flattening yuav qhia tau cov yeeb nkab ntev thiab cov kab nrib pleb tsis kam.

CVN impact test
CVN cuam tshuam kev ntsuas yog qhov ntsuas kub tau ua thaum lub sijhawm tsim cov yeeb nkab los xyuas kom meej cov khoom siv ntawm cov yeeb nkab. Cov kev ntsuam xyuas tau ua nyob rau ntawm peb qhov chaw sib txawv ntawm cov yeeb nkab: yeeb nkab lub cev, vuam seam thiab tshav kub- thaj tsam cuam tshuam. Cov txiaj ntsig kev sim yog siv los txiav txim siab Charpy V-qhov cuam tshuam ntawm lub zog ntawm cov yeeb nkab.

Yuav ua li cas tuav lub laum yeeb nkab?
1. Kev saib xyuas tsis tu ncua: Drill yeeb nkab yuav tsum tau khaws cia tsis tu ncua. Lub voj voog tu yuav tsum tau txiav txim siab raws li kev siv ib puag ncig thiab huab cua av noo, thiab tiv thaiv - xeb roj thiab hmoov av- pov thawj kev kho yuav tsum tau ua tsis tu ncua.
2. Kev siv tsim nyog: Laum yeeb nkab yuav tsum tau siv nyob rau hauv qhov ntsuas qhov deb ntawm qhov drilling rig. Raws li qhov kev ncua deb ntawm qhov drilling thiab cov kev tsis sib xws ntawm cov qauv drilling rig, xaiv cov yeeb nkab sib txuas.
3. Kev tshuaj xyuas thiab kev hloov pauv: Thaum khoov ntawm cov yeeb nkab laum tshaj li cov qauv yuav tsum tau lossis cov xov puas lawm thiab tsis tuaj yeem ua haujlwm li qub tom qab siv, nws yuav tsum tau muab pov tseg lossis rov qab mus rau lub Hoobkas kom kho raws sijhawm.
4. Ua tib zoo saib xyuas cov txheej txheem drilling: Thaum lub sij hawm drilling txheej txheem, koj yuav tsum nco ntsoov ua tib zoo saib xyuas qhov xwm txheej ntawm qhov drilling rig thiab laum yeeb nkab. Yog hais tias qhov kev sib tsoo los yog kev sib tsoo tshwm sim, qhov drilling yuav tsum tau nres tam sim ntawd los yog drilled rov qab thiab maj mam drilled kom ntseeg tau tias lub laum yeeb nkab tsis khoov lossis deform.
5. Acid thiab alkali ib puag ncig kev kho mob: Thaum ua haujlwm hauv thaj chaw acid thiab alkali, yuav tsum tau them nyiaj rau corrosion ntawm cov kav dej. Tom qab drilling ua tiav, qhov saum npoo ntawm lub cev pas nrig yuav tsum tau ntxuav nrog dej huv hauv lub sijhawm kom tshem tawm cov txheej txheem corrosion.
Yuav khaws cov yeeb nkab li cas?
1. Qhov chaw khaws cia: Qhov chaw khaws cia yuav tsum tiaj tus, zoo-drained, thiab zam kom tsis txhob muaj dej ntau, tshav ntuj ncaj qha, thiab noo noo los ntawm nag thiab daus. Lub laj kab yuav tsum tau teeb tsa rau ntawm qhov chaw nrog qhov siab tsis pub tsawg tshaj 2 meters los tiv thaiv cov neeg sab nraud los ntawm kev nkag mus thiab tiv thaiv cov yeeb nkab laum.
2. Txoj kev khaws cia: Thaum khaws cov yeeb nkab laum, nws yuav tsum tau muab tso rau hauv vertically thiab sim kom tsis txhob muaj cov yeeb nkab laum ntog los yog kab rov tav. Qhov no txo qis tus nqi dabtsi yog khoov thiab ua kom yooj yim rau kev soj ntsuam ntawm cov tho yeeb nkab ntev, txoj kab uas hla thiab cov duab.
3. Kev cia khoom: Lub laum yeeb nkab yuav tsum tau muab cia rau hauv qhov chaw qhuav, thiab hauv qab yuav tsum tau txhawb nqa ntawm ntau lub ntsiab lus kom tsis txhob deformation. Laum yeeb nkab yuav tsum tau khaws cia tsis tu ncua thaum lub sij hawm ntev - cia.
4. Kev tuav cov ntsaws ruaj ruaj: Yog tias cov yeeb nkab laum muaj cov ntsaws ruaj ruaj (xws li O-rings), yuav tsum tau them tshwj xeeb rau kev siv cov ntsaws ruaj ruaj. Thaum kev puas tsuaj, corrosion, thiab lwm yam tshwm sim, cov ntsaws ruaj ruaj yuav tsum tau hloov raws sij hawm. Tom qab drilling tiav, lub foob yuav tsum tau khaws cia thiab ntxuav.
5. Tsis txhob hnyav hnyav: Cov kav dej laum yuav tsum tsis txhob siv los ua lub platform txhawb nqa hnyav - lub luag haujlwm tail stacking, thiab cov kav dej laum yuav tsum tsis txhob muab tso rau hauv cov pob zeb lossis cov thee los yog muab tso ua ke.
