Vim li cas thiaj xaiv ERW Casing rau Dej Dej
- Tus nqi qis dua ib ko taw- ERW casing los ntawm coil feem ntau yog kev lag luam ntau dua li cov yeeb nkab seamless, uas tseem ceeb ntawm qhov dej tob uas ntau pua taw ntawm cov casing xav tau.
- Uniform roundness thiab phab ntsa thickness- pab xyuas kom muaj qhov sib npaug ntawm qhov chaw rau grouting thiab txo qhov kev pheej hmoo ntawm kev tshuaj ntsuam los yog twj tso kua mis misalignment.
- Teb-weldable pob qij txha- tiaj-kawg ERW casing tuaj yeem ua pob tw-welded rau ntawm qhov chaw kom ncav cuag qhov tob tob yam tsis muaj kev vam khom cov xov txuas, uas yog tus qauv coj los siv rau hauv nroog thiab cov dej ntws.
- Standard muaj nyob rau hauv cov qib- ASTM A53, API 5L, thiab EN 10219/10217 yog tag nrho cov siab - ntim, cov khoom lag luam dav dav, yog li qhov loj me thiab phab ntsa- cov kev xaiv tuab feem ntau muaj yam tsis muaj sij hawm ua cov hmoov txhuas ntev.
Qhov twg ERW Water Well Casing yog (thiab tsis yog) txoj kev xaiv
- ERW (High-Frequency Electric Resistance Welded) casing yog tsim los ntawm steel strip dov, siab-frequency solid-lub xeev vuam, weld hlaws tshem tawm, thiab ib qho tseem ceeb normalizing kev kho cua sov; Cov qauv siv tau suav nrog ASTM A53 Gr.B, API 5L Gr.B, AWWA C200.
- Qhov zoo: High phab ntsa thickness precision; Cov khoom lag luam txaus muaj rau cov kab loj loj; cov nqi tsim khoom 20% -40% qis dua seamless casing; du sab hauv phab ntsa kom ntseeg tau cov yam ntxwv zoo ntws; thiab zoo ib yam threading zoo.
- Cov kev txwv tsis pub muaj: Muaj qhov ntev ntawm qhov vuam seam, nrog lub tshav kub - cuam tshuam cheeb tsam (HAZ) ua qhov tsis muaj zog rau kev ntxhov siab lossis corrosion; tsis kam mus rau cyclic compression, kub kub, corrosion hnyav, thiab huab cua sab nraud yog qis dua li ntawm seamless casing.
| Judging Factor | Haum rau ERW Casing | Unsuitable (yuav tsum tau seamless casing) |
|---|---|---|
| Zoo Qhov tob | Tsawg dua los yog sib npaug li 600m | ≥800m qhov dej tob |
| Hydrostatic siab | Tsawg siab tsawg dua los yog sib npaug rau 10MPa | Siab siab ＞ 12MPa / fluctuating siab |
| Stratum mob | Homogeneous xuab zeb / av nplaum, zoo li txaj txaj tsis muaj qhov txhaum | Cov chaw tawg, pob zeb ntsev, pob zeb nthuav dav, siab hauv -situ stress |
| Cov dej hauv av zoo | Cov dej tshiab, TDS tsawg, tsis muaj roj corrosive | High chloride, H₂S, acidic siab -mineralized dej |
| Dej kub | Qhov ntsuas kub ruaj khov ＜60 degree | ＞ 100℃qhov dej kub hauv qhov dej, nquag kub -txias mus |
| Tsim Kev Pabcuam Lub Neej | Lub qhov dej ib ntus (3-8 xyoo), qhov dej ua liaj ua teb | Lub qhov dej tseem ceeb hauv nroog, 30+ xyoo ntev - lub qhov dej dej |
| Txoj kev tsim kho | Smooth rotary drilling txo qis | Rauj tsav tsheb, ntse khoov khoov |
Cov ntsiab lus
- Tus nqi zoo tshaj -Kev Ua Tau Zoo: ERW casing yog thawj qhov kev xaiv rau cov qhov dej ua liaj ua teb, cov qhov dej haus nyob deb nroog thiab cov qhov dej dewatering ib ntus hauv qhov tob ntawm 600m, nrog cov strata ruaj khov thiab tsis yog -cov dej hauv av corrosive.
- Kev txwv tsis pub muaj zog: ERW casing tsis pom zoo rau cov qhov dej tob tshaj 800m, txhaum- cov kab nrib pleb tawg, dej hauv av corrosive siab, siab - qhov kub kub hauv qhov dej kub, siab - qhov dej txhaj tshuaj thiab cov dej hauv nroog loj nrog 30+ xyoo tsim lub neej. Seamless casing muab kev ruaj ntseg ntau dua.
- Kev sib haum xeeb: Rau qhov nruab nrab - qhov tob tob nrog me me corrosion thiab siv nyiaj tsawg, tsuas yog cua sov- kho hnyav los tiv thaiv -corrosion siab- qib ERW casing tau txais, nrog rau cov phab ntsa tuab thiab tag nrho cov vuam tsis muaj - kev puas tsuaj.
Cov Lus Qhia Ua kom zoo rau ERW Casing Application
- Kev xaiv qib khoom: Txais HFI siab- zaus tshav kub- kho ERW casing nrog tag nrho weld normalizing; zam qis-qib ERW nrog yooj yim annealing nkaus xwb.
- Los tiv thaiv-Kev sib txuam ntawm kev sib tsoo: Cov dej haus dej tau txais cov epoxy hauv ob sab phlu + sab nraud kub-dip galvanizing / 3PE, nrog rau cov txheej txheej tuab ntawm cov cheeb tsam weld.
- Phab ntsa Thickness Upgrading: Rau nruab nrab siab los yog me ntsis corrosive formations, nce phab ntsa thickness los ntawm 1-2mm tshaj theoretical xam los them nyiaj txo weld zog.
- Tsis yog-Kev Ntsuas Kev Ua Phem: Tag Nrho- ntev weld ultrasonic UT tshuaj xyuas thaum xa khoom kom tshem tawm qhov tsis tiav fusion thiab slag suav nrog qhov tsis xws luag.
- Kev Tswj Xyuas Kev Tsim Kho: Tiv thaiv casing kev sib tsoo ntawm phab ntsa borehole thaum txo qis; txwv tsis pub quab yuam ntse bending ntawm casing seem.
Cov lus nug nquag nug (FAQ)
Q: Puas yog ASTM A53 lossis API 5L yeeb nkab tau txais kev pom zoo rau kev siv dej hauv qhov dej?
A: Tsis yog ASTM A53 lossis API 5L yog cov yeeb nkab - tshwj xeeb "dej zoo" tus qauv - lawv yog dav dav - lub hom phiaj welded steel yeeb nkab qauv. Kev siv lawv li cov dej hauv lub qhov dej yog qhov ntau, lees paub kev lag luam rau ntau lub qhov dej, tab sis nws yog tus neeg yuav khoom lossis tus kws ua haujlwm lub luag haujlwm kom paub meej txog cov cai hauv zos lossis qhov kev qhia tshwj xeeb tso cai rau tus qauv dav dav - cov qauv yeeb nkab es tsis xav tau cov dej tshwj xeeb - cov kav dej zoo.
Q: Qhov txawv ntawm ASTM A53 thiab API 5L casing yog dab tsi?
A: ASTM A53yog ib qho kev siv tshuab dav dav thiab qis / nruab nrab- cov kav dej siab feem ntau siv hauv kev tsim kho thiab kev pabcuam dej; API 5L yog cov qauv kev thauj mus los hauv cov raj xa dej nrog qee qhov kev siv tshuaj lom neeg nruj dua thiab cov kev xeem yuav tsum tau ua thiab siab dua - kev xaiv qib siab (X42, X52, thiab lwm yam). Rau qhov dej hauv qhov dej, tuaj yeem ua haujlwm -API 5LCov qhab nia feem ntau muaj qhov tsawg dua qhov muaj peev xwm ua tau zoo dua qhov twg qhov tseem ceeb.
Q: Puas yog ERW casing muaj kev nyab xeeb rau cov dej haus?
A: Standard carbon steel ERW casing yog dav siv nyob rau hauv potable dej qhov dej, tab sis yog hais tias qhov project tshwj xeeb yuav tsum tau NSF / ANSI 61 ntawv pov thawj (ntaus rau lub nroog mov qhov dej), paub meej tias cov txheej txheej thiab zeb certification tau ntawv pov thawj rau lub hom phiaj ntawd - tsis txhob xav tias tus qauv zeb{{2} tiav.
Q: Qhov loj casing kuv xav tau rau kuv lub qhov dej?
A: Casing txoj kab uas hla yog tsav los ntawm lub twj tso kua mis txoj kab uas hla thiab clearance, tsis yog los ntawm lub drilled borehole loj ib leeg. Ib txoj cai ntawm tus ntiv tes xoo yog tsawg kawg yog 2 ntiv tes ID loj dua lub twj tso kua mis, tab sis qhov loj me yuav tsum tau lees paub tawm tsam AWWA A100 kev taw qhia thiab koj cov chaw tsim khoom tshwj xeeb cov twj tso kua mis tshem tawm.
