Lub cev muaj zog
Lub slotted casing kav siv nyob rau hauv kev tshawb nrhiav roj tuaj yeem tiv thaiv 99% xuab zeb, txo 80% ntawm cov roj zoo hnyav, thiab ua kom lub zog ntawm cov roj zoo, kev ncaj ncees thiab kev ruaj ntseg ntawm kev khaws cov xuab zeb.Meanwhile, lub laser incision tech yuav ua rau lub qhov yuav du thiab precision.Cov qauv ntawm slotted casing yeeb nkab yog cov qauv, tab sis nws ua haujlwm zoo heev.
Kev ua cov raj xa dej yog nyob ntawm lub zog siab steel lub cev nrog txoj kev ua haujlwm txias lossis kub, txiav tawm ntau pua txhiab tus kab nrib pleb ntev, cov kab nrib pleb feem ntau siv rau: seam dav 0.15 3 hli, dav dav, qhov sib txawv ntev 50-200 mm.Cross seem hom yog: duab plaub, ntaiv zoo li tus, tshwj xeeb thiab ntau yam, kuj muaj ib lub voj voj voos npo, aperture txoj kab uas hla specifications thaj tsam 5-20 hli hauv meters.Slotted sieve raj qhov seam txiav zoo feem ntau yog nyob ntawm qhov precision seam dav, qhov seam cross- seem zoo zoo degree, ntawm ntug ntawm lub qhov seam smoothness thiab degree ntawm corrosion kuj ntawm qhov seam.
Ncaj Slots-Slots raug txiav nrog qhov dav sib npaug los ntawm phab ntsa ntawm cov yeeb nkab ob leeg ID thiab OD.Qhia meej qhov twg cov xuab zeb bridging ntawm lub qhov tsis yog qhov tseem ceeb, cov kab ncaj nraim yog hnav-tiv taus ntau dua li cov pob zeb tseem ceeb seamed thiab tsis tshua muaj nqi los tsim.Cov kev siv feem ntau ntawm Kev Ncaj Ncees Ncaj Ncees yog rau Cold Production thiab CBM kab rov tav qhov ntxiv rau SAGD cov qhov dej txhaj tshuaj.
Seamed Keystone Slots--yog milled wider ntawm cov yeeb nkab sab hauv thiab yog tus kheej tu los pab tiv thaiv plugging.Nqaim ntawm liner nto thiab nce nyob rau hauv dav ntawm sab hauv, lawv cia cov xuab zeb uas nkag mus tau yooj yim los ntawm cov slots yam tsis muaj ntsaws.
