3LPE anti-corrosive steel raj muab faib ua qib dav thiab ntxiv dag zog rau qib.Lawv lub hauv paus sib txawv nyob ntawm qhov sib txawv thickness.Rau cov kev qhia tshwj xeeb ntawm 219-478, lub thickness yog nyob ib ncig ntawm 2.0 hli, thiab qhov ntxiv dag zog ib ncig ntawm 2.7 hli.Lawv cov nqi muaj qhov sib txawv ntawm li 7 yuan ib square meter.Xaiv cov qib twg ntawm cov tshuaj tiv thaiv corrosive raws li cov neeg siv khoom tshwj xeeb.Yog hais tias siv raws li zoo tib yam sab nraum casing corrosion, hom qib yog ntau tshaj li txaus.Yog tias siv los hloov cov kua dej ncaj qha, xws li kua qaub thiab alkali lossis roj, ntxiv dag zog rau ib qho zoo dua.Txij li thaum 3 PE tiv thaiv corrosive kauv hlau tau tsim thoob ntiaj teb thawj-chav tsim khoom kom paub txog kev txuag hluav taws xob hauv Suav teb, peb lub Hoobkas tau cog lus los ua cov haujlwm ntawm kev txuag hluav taws xob xa hluav taws xob, kev tshawb fawb thiab kev loj hlob.Lub advent ntawm 3 PE anti-corrosive yeeb nkab yog qhov zoo tshaj plaws channel ntawm natural gas tsheb thauj mus los.Tab sis qhov xwm txheej ntawm cov yeeb nkab tsis sib haum hauv tsev tau nthuav tawm txawv teb chaws tau ua rau cov neeg caws pliav rau ntau xyoo.

3LPE anti-corrosion steel tube chaw tsim khoom siv tes ua khoom siv tes ua yog qib siab tiv thaiv corrosion uas tau qhia los ntawm txawv teb chaws thaum xyoo 1990.Nws lub npe tag nrho yog fusion bonded epoxy / extruded polyethylene tiv thaiv txheej txheej.3 PE anti-corrosion txheej tshuab colligates nplhaib oxygen thiab extruded polyethylene ob hom anti-corrosive txheej uas muaj kev ua tau zoo, nrog kev sib txuas ntawm cov khoom sib txuas ntawm epoxy txheej thiab tshuaj lom neeg cov yam ntxwv thiab qhov zoo ntawm extruded polyethylene anti-corrosive txheej tiv thaiv kev tiv thaiv. .Li no nws tuaj yeem txhim kho lawv txoj kev sib deev.Yog li, 3 PE txheej yog qhov zoo tshaj plaws ntawm faus cov kav dej sab nrauv tiv thaiv.Raws li cov ntaub ntawv pov thawj pom, lub neej ua haujlwm ntawm cov kav dej faus nrog 3 PE anticorrosive thev naus laus zis tuaj yeem ncav cuag 50 xyoo.Tam sim no, lub network tseem ceeb ntawm cov kav dej hauv Suav teb tau txais 3 PE tiv thaiv txheej sab nraud, ntau lub raj xa dej txawv teb chaws kuj tau txais cov thev naus laus zis no.

Tsis ntev los no, Ministry tau tshaj tawm Cov Lus Qhia Txog Kev Ua Haujlwm Txhawb Kev Txhim Kho Cov Ntaub Ntawv Loj ntawm Kev Siv Av thiab Kev Pabcuam.Thaum lub sij hawm "ntau qhov kev xaiv-thiab qhov tshwm sim loj heev-hauv" lub sijhawm, sib koom ua ke thaj av, vaj tse, geology thiab cov peev txheej ntxhia thiab lwm yam ntaub ntawv, tsim thiab txhim kho kev nthuav dav, tus qauv thiab kev sib koom ua ke ntawm cov ntaub ntawv ntawm thaj av thiab cov peev txheej.
